Chapter One: Introduction  
Introducing the DIVA LAN ISDN Modem 10  
Introducing the DIVA LAN ISDN Modem  
The DIVA LAN ISDN Modem is a powerful networking solution for SOHO (small office/home office) and  
branch office users. It creates a complete networking, phone, fax, and data communications system in one box.  
The DIVA LAN ISDN Modem is easy to install, use, and maintain, without the need for technical support from  
the remote, corporate office.  
The DIVA LAN ISDN Modem can be used in a variety of applications. This section presents a brief overview  
of some of the more common applications, and their features.  
Creating your own LAN for resource sharing  
The DIVA LAN ISDN Modem has a built-in 10 Mbps Ethernet hub with four ports. By connecting computers  
(or other devices, such as printers) to these ports, they become part of a LAN (local area network), and can  
share data and resources with each other.

How it works: You connect the DIVA LAN ISDN Modem to an ISDN line (which is part of the telephone network).  
You also set up an account with an ISP (Internet Service Provider), obtaining the necessary phone numbers, user  
name, and password. Once the DIVA LAN ISDN Modem is configured with this information, it automatically calls  
the ISP and uses its services to send and receive data on the Internet.

Corporate Network  
How it works: You connect the DIVA LAN ISDN Modem to an ISDN line (which is part of the telephone  
network). You also contact the corporate network and obtain its ISDN phone number and associated user  
names and passwords. Once the DIVA LAN ISDN Modem is configured with this information, it automatically  
calls the remote site to send data to it, for example, when a local users sends e-mail, or shares folders with  
Windows Network Neighborhood.  
Note You cannot connect to a corporate network if it is also using a DIVA LAN ISDN Modem.  
Creating a VPN  
Connect branch offices and telecommuters into an enterprise-wide Virtual Private Network (VPN) over the  
Internet. This eliminates the long-distance charges, network management problems, and security  
responsibilities associated with traditional WANs.

Attaching telephones and fax machines  
The DIVA LAN ISDN Modem is available in a version that features two analog ports for the connection of  
telephones, fax machines, and analog modems. The DIVA LAN ISDN Modem takes advantage of the  
flexibility of ISDN to enable you to make or receive phone calls or faxes, while at the same time connecting to  
the Internet or a corporate network with your computers. This can eliminate the need to install additional  
analog phone lines.

In this example, all computers can share the ISDN link to exchange data, send e-mail, or surf the Web. There is  
no need for multiple modems, phone lines, or ISP accounts.  
Note Two DIVA LAN ISDN Modems cannot be connected in this manner.  
Total network security  
The Network Address Translation (NAT) feature keeps local IP addresses hidden so that your computers are  
invisible to the outside world.  
Password security, filtering, and the ability to disable support for incoming calls prevents intruders from  
breaking into the DIVA LAN ISDN Modem itself.  
Compression for faster throughput  
The DIVA LAN ISDN Modem provides data compression to achieve throughput rates of up to 512 kbps. That's  
four times the ISDN remote access speed of 128 kbps.

The DIVA LAN ISDN Modem's bandwidth-on-demand feature automatically monitors data traffic and  
engages the second B-channel only when needed, reducing ISDN costs.  
Advanced ISDN tariff management  
The DIVA LAN ISDN Modem can be configured to:  
• Disable ISDN access during peak tariff rates or limit the total line usage in minutes for a given time  
period.  
• Set a maximum number of connections for a given period.  
• Filter out specific IP protocols which consume a lot of bandwidth.  
• Control broadcast traffic such as NetBEUI and TCP from reconnecting the ISDN line.  
Advanced diagnostics  
• On-screen display of B-channel status.  
• Significant events are recorded in the Event Viewer.  
• Events trigger visual or audible alarms.  
• Common errors are described in non-technical language inside the Event Viewer, so that users don’t need  
to analyze PPP or ISDN traces.  
• Detailed ISDN information for the last two calls is retained.  
• Reports list ISDN diagnostics in plain language along with help information. This is particularly useful  
for solving ISDN line provisioning problems.  
• Detailed traces (including ISDN (Q.931), PPP, X.25, LAPD) are available enabling technical personnel to  
isolate complex communications problems.  
Unsupported configurations  
The DIVA LAN ISDN Modem cannot be used in the following configurations:  
• Two DIVA LAN ISDN Modems cannot be interconnected (daisy-chained) via their Ethernet ports.  
• The DIVA LAN ISDN Modem cannot be used on both sides when connecting to a corporate network. The  
corporate network must have its own gateway.

To configure the DIVA LAN ISDN Modem  
The computer you are going to use to configure the DIVA LAN ISDN Modem must have:  
• Web browser software (Netscape 3.01 or later, or Internet Explorer 4 or later).  
Internet Explorer 4 is included on the DIVA LAN ISDN Modem CD for computers running Windows 95,  
Windows 98, or NT 4.0 or later. NT 4.0 requires SP3 or SP4 available on the DIVA LAN ISDN Modem CD.  
• The Web browser must be configured as follows:  
• Connect to the Internet via a local area network (LAN).  
• Do not to connect through a proxy server.  
To run the Modem Monitor software  
The Modem Monitor software provides an easy way to manage the DIVA LAN ISDN Modem. To install and  
run this software you need:  
• IBM-compatible 486, or Pentium-based computer running Microsoft Windows 95/98/NT4.0 or later  
• CD-ROM drive  
To use the advanced configuration options  
For the advanced user, the DIVA LAN ISDN Modem offers additional configuration options. These options  
and their requirements are as follows:  
• The command line interface (CLI) gives you complete access to all the DIVA LAN ISDN Modem  
configuration parameters. To access this interface you require Telnet software or a terminal emulation  
program.  
• TFTP (trivial file transfer protocol) gives you access to all configuration files on the DIVA LAN ISDN  
Modem. You need TFTP client software to use this option. A TFTP program is included on the DIVA LAN  
ISDN Modem CD.  
• The DTMF interface enables you to define certain DIVA LAN ISDN Modem configuration settings using  
a ordinary touch tone phone.  
See Chapter Ten for more information on these configuration options.

3. Choose a connection protocol 20  
3. Choose a connection protocol  
The usage of the ISDN link is governed by the type of connection protocol you choose. The connection  
protocol defines the rules by which ISDN channels are enabled and disabled. The type of protocol you choose  
to use depends on the type of connections you plan to make.  
Important ISDN concepts  
Before you can decide on a connection protocol, you must become familiar with the following ISDN concepts.  
ISDN channels  
ISDN lines are defined in terms of channels, with each channel supporting a specific type of communication.  
The DIVA LAN ISDN Modem supports two ISDN channel types:  
• D-channel: The Device channel is used to control the setup of ISDN connections on the other channels.  
They can also be used to transmit packet data traffic. The D-channel has a transmission speed of 16 kbps.  
• B-channel: Bearer channels are used to carry data or voice traffic. They have a transmission speed of 56  
or 64 kbps.  
ISDN access interfaces  
An access interface is the physical connection between you and an ISDN network. It defines the number of D-  
and B-channels that are available to you and the total transmission speed of the connection. The DIVA LAN  
ISDN Modem supports a single Basic Rate Interface (BRI), which is comprised of one D-channel (16 kbps)  
and two B-channels (64 kbps) for a total user bit rate of 144 kbps.  
Each ISDN B-channel can have its own telephone number. Although in some cases you will only get one  
number for both channels unless you order supplementary services.  
ISDN channel usage  
The following diagram shows all the potential connections a DIVA LAN ISDN Modem could make, if it was  
configured to support an Internet connection, a corporate network connection, incoming data calls, and analog  
calls on both PHONE ports.  
Internet Connection  
ISDN BRI Line  
Corporate Network Connection  
Incoming Data Call Connection  
PHONE port #1  
D-channel  
1st B-channel  
2nd B-channel  
PHONE port #2  
All connections, both data and voice, are carried on the B-channels. (AO/DI enables you to also use the  
D-channel for data connections, but this exception will be discussed later.) The DIVA LAN ISDN Modem  
dynamically assigns B-channels on-demand. Therefore, there is no guarantee which B-channel a specific  
connection will receive. The same is true for your ISDN phone numbers and your SPIDs. Your first phone  
number does not necessarily map to ISDN channel B1.  
Connections are mapped as follows:  
• PHONE port 1 always uses the first ISDN phone number (and SPID).  
• PHONE port 2 always uses the second ISDN phone number (and SPID).  
• To help avoid conflicts, the DIVA LAN ISDN Modem always tries to establish data connections using  
phone number 2 first, in an attempt to leave PHONE port 1 free. Of course, if phone number 2 is in use,  
the data connection is established using phone number 1.  
• When an analog or data connection is established, the first available ISDN B-channel is assigned to it.

Chapter Two: Getting Started  
3. Choose a connection protocol 21  
Choosing a connection protocol  
Since the DIVA LAN ISDN Modem supports so many potential connections, a set of rules is needed to control  
how the two ISDN B-channels are shared between connections. These rules are based on the type of  
connection protocol you decide to use for your data traffic. The DIVA LAN ISDN Modem supports the two  
protocols: PPP and V.120.  
• PPP is a widely-used standard for transferring data on point-to-point links. The DIVA LAN ISDN Modem  
supports four variations of the PPP protocol: PPP, Multilink PPP, Multilink PPP+BACP, and Multilink  
PPP+AO/DI. Each version has its own specific features as detailed later in this section.  
• V.120 was designed to allow non-ISDN devices to communicate with the ISDN network. The DIVA LAN  
ISDN Modem provides support for V.120, so you can connect with such legacy systems. For example, in  
many countries around the world, Compuserve offers access to their network over ISDN, using the V.120  
protocol.  
By choosing the correct protocol variation for your connection, you control how the ISDN channels are  
assigned and how the DIVA LAN ISDN Modem provides support for analog calls.  
PPP  
PPP operates on a single ISDN B-channel. Since two B-channels are available, the DIVA LAN ISDN Modem  
can support two PPP connections at the same time. This is useful if you need to have two connections that need  
to be established at the same time. For example, to maintain a connection to the Internet and to a remote  
corporate network, or if you intend to support incoming data calls.  
By default, the DIVA LAN ISDN Modem is configured to support call bumping. However, a PPP connection  
will never be disconnected to allow an incoming or outgoing analog call to connect. If two PPP connections are  
active, no analog calls can be made or received.  
Multilink PPP  
When you activate multilink PPP (MLPPP), the DIVA LAN ISDN Modem combines both your B-channels  
into a single 128 kbps communications link. Both B-channels remain in use as long as the connection is active,  
which may result in excessive ISDN connection charges if the link is frequently idle.  
MLPPP reserves both B-channels for its exclusive use. This means that if your Internet connection uses  
MLPPP, you will not be able to make or receive other data calls.  
Analog calls, however, are governed by a different set of rules. By default, the DIVA LAN ISDN Modem is  
configured to support call bumping. Call bumping causes MLPPP to drop one B-channel when you make or  
receive an analog call. This reduces the throughput of the data call to 64 kbps. When the analog call is done,  
MLPPP re-establishes the second B-channel, returning the data connection to 128 kbps.  
Only one PHONE port can be used when an MLPPP connection is active. This can be either PHONE 1 or  
PHONE 2.  
Multilink PPP + BACP  
To save on communications charges, you can use BACP in combination with MLPPP. The DIVA LAN ISDN  
Modem uses BACP to monitor incoming and outgoing traffic, and to open or close the second B-channel as the  
traffic volume warrants. This reduces your communications charges by ensuring that two ISDN channels are  
never active when one is sufficient. For information on how to configure BACP, see “Configuring BACP” on  
page 61.  
As with MLPPP, MLPPP + BACP reserves both B-channels for its exclusive use. This means that if your  
Internet connection uses MLPPP + BACP, you will not be able to make or receive other data calls.  
As with MLPPP, call bumping causes MLPPP + BACP to drop one B-channel (if both are active), when you  
make or receive an analog call.

Chapter Two: Getting Started  
3. Choose a connection protocol 22  
Only one PHONE port can be used when an MLPPP + BACP connection is active. However, since MLPPP +  
BACP may only be using one B-channel, either PHONE 1 or PHONE 2 may not be available. For example, if  
PHONE 2 was in use when the data connection was established, the data connection uses telephone number 1.  
Even though telephone number 2 becomes available when PHONE 2 hangs up, the data connection does not  
switch over. If you try to use PHONE 1, you will get a busy signal.  
Multilink PPP + AO/DI  
Always On/Dynamic ISDN uses the ISDN D-channel to maintain a permanent connection to your ISP or  
corporate network. This connection operates at 9.6 kbps using the X.25 protocol. It can be used to send and  
receive low-bandwidth data, such as e-mail or web-based push content.  
AO/DI incorporates BACP, and uses it to monitor incoming and outgoing traffic. When traffic volume  
warrants, it enables one or two B-channels to meet the demand. For information on AO/DI, see “Configuring  
AO/DI” on page 63.  
As with MLPPP, MLPPP + AO/DI reserves both B-channels for its exclusive use. This means that if your  
Internet connection uses MLPPP + AO/DI, you will not be able to make or receive other data calls.  
MLPPP + AO/DI can drop both B-channels, allowing you to make or receive two analog calls. Since the data  
connection is still active on the D-channel, you can use both phone ports at any time. Note, however, that the  
speed of the D-channel (9.6 kbps) is much slower than a B-channel (64 kbps).  
V.120  
V.120 was designed to allow non-ISDN devices to communicate with the ISDN network. The DIVA LAN  
ISDN Modem provides support for V.120, so you can connect with such legacy systems. For example, in many  
countries around the world, Compuserve offers access to their network over ISDN, using the V.120 protocol.  
V.120 operates on a single ISDN B-channel. Since two B-channels are available, the DIVA LAN ISDN Modem  
can support two V.120 connections at the same time. In general, you should use V.120 only when the site you  
are connecting to requires it. Once the V.120 connection is active, the DIVA LAN ISDN Modem automatically  
establishes a PPP connection on top of it. This is why you will see this option listed as PPP over V.120 on the  
configuration screens.  
A V.120 connection will never be disconnected to allow an incoming or outgoing analog call. If two V.120  
connections are active, no analog calls can be made.  
Summary  
The following summary will help you determine how ISDN channels are assigned by the various connection  
protocols. This summary assumes that call bumping is enabled.  
• If a data connection using any MLPPP-related protocol is connected, it reserves both ISDN B-channels.  
This means that no other data call can be established.  
• If a data connection using MLPPP is connected, only one PHONE port can be used at a time.  
• If a data connection using MLPPP-BACP is connected, one PHONE port (in most cases PHONE 2), will  
not be available.  
• If a data connection using MLPPP-AO/DI is connected on one or both ISDN B-channels, one or both  
B-channels will be dropped to allow an incoming or outgoing analog call to connect.  
• Data connections using PPP or V.120 are established first on telephone number 1, then on telephone  
number 2. If two PPP or V.120 data connections are active, no PHONE ports are available.  
• If both PHONE ports are in use, no data calls can be established. Unless you are using AO/DI, which can  
make use of the D-channel.

4. Order an ISDN Line 23  
4. Order an ISDN Line  
Call your local phone company and order an ISDN Basic Rate line.  
To make ordering an ISDN line easier, Bellcore, in conjunction with the North American ISDN User’s Forum  
(NIUF) and Local Exchange Carriers (LEC), have created several pre-defined ISDN packages which you can  
order by simply specifying an ISDN ordering code (IOC).  
Ordering Code  
Features  
EZ-ISDN 1 or  
IOC: “U”  
Offers voice and data on both ISDN channels and supports advanced calling features such  
as call conference, call transfer, and caller ID on the first ISDN number. You may have to  
request these features individually, and there may be an additional charge for each one.  
EZ-ISDN 1A or  
Same as EZ-ISDN 1, but adds Voice Mail support.  
IOC: “V”  
IOC: “S”  
Offers voice and data on both B-channels, but without any advanced calling features. If  
you select this package, be sure to get Additional Call Offering (ACO). ACO is required  
for call bumping (also known as dynamic bandwidth allocation) and call waiting to work  
correctly. IOC “S1” includes ACO, however it is not supported everywhere.  
EZ-ISDN 3 or 3A  
If you want to use Always On/Dynamic ISDN (AO/DI).  
Capability Package AB Same as IOC U, but with advanced calling support on both channels and support for  
AO/DI.  
Capability Package AC Same as IOC V, but with advanced calling support on both channels and support for  
AO/DI.  
Information to record when ordering your line  
Item  
Description  
ISDN phone number(s) The phone number assigned to your ISDN line. Some providers will give you two phone  
numbers—one for each ISDN channel.  
SPID(s)  
SPIDs (service profile IDs) identify the set of features and services provided by the ISDN  
switch to which the ISDN device is connected.  
When you subscribe to an ISDN line your provider allocates a SPID in the same way they  
allocate an ISDN phone number. In some cases, the SPID is the same as the phone  
number, in other cases it is the phone number with other digits added to it. It depends on  
your provider.  
Find out if your ISDN line supports AutoSPID. AutoSPID is a new National ISDN  
protocol feature that enables the DIVA LAN ISDN Modem to automatically configure all  
parameters for your ISDN line.  
However, even if your ISDN line supports AutoSPID, it is a good idea to write down your  
SPIDs.  
Switch type  
The type of ISDN switch used by your provider. During configuration, the DIVA LAN  
ISDN Modem automatically tries to detect the switch type your line is connected to.  
However, if auto-detection fails, you need to manually specify the switch type. Three  
types are supported: National ISDN-1, AT&T 5ESS, or AT&T 5ESSPP (5ESS  
Point-to-Point).  
Billing intervals  
Find out how your provider bills for ISDN usage. With this information on hand you can  
configure the DIVA LAN ISDN Modem to minimize your connection costs. See

V.120 scripting  
To successfully log on to your ISP, you will need to define a script to automatically execute the log on process  
for you. The DIVA LAN ISDN Modem contains a pre-defined script that should work in the majority of cases.  
However, you may need to modify this script for your installation.  
To modify this script, you need to determine the sequence of events that occur when logging on to your ISP,  
and the input that must be sent. For example:  
• Step 1: Your ISP issues the prompt “Login:” and expects you to send your user name, then press Enter.  
• Step 2: Your ISP issues the prompt “password:” and expects you to send your password, then press Enter.

The Web-based Configuration Interface  
The DIVA LAN ISDN Modem uses a single ISDN link to provide communications services for all  
your connected devices. It manages incoming and outgoing data calls from your computers, as well  
as incoming and outgoing analog calls from connected telephones and/or fax machines.  
To accomplish all this, the DIVA LAN ISDN Modem implements a number of important ISDN  
features that enable complex communications requirements to be supported on a single link. When  
you define your setup with the Internet wizard, a number of parameters are set to default values that  
give good results for most cases. However, due to the number of options that are available, the Internet  
wizard cannot fine tune all settings for your particular installation. For optimal performance, or to  
define a custom setup, you must manually adjust the configuration of the DIVA LAN ISDN Modem.  
The web-based configuration interface provides you with an easy way to manage the configuration  
of the DIVA LAN ISDN Modem, and perform other tasks like viewing status and statistics on your  
connections, and updating your system firmware.  
This chapter explains how to access the web-based configuration interface, and gives step-by-step  
instructions for some common tasks.

Minimizing ISDN Charges  
ISDN billing practices vary from flat-rate monthly services to per-call billing to per-minute usage  
fees. To help you reduce your ISDN charges, the DIVA LAN ISDN Modem provides you with several  
cost-cutting configuration options. Use this chapter to find the best options for use on your ISDN line.

The Cost Control page 59  
The Cost Control page  
For your convenience, the DIVA LAN ISDN Modem groups the most commonly used options for reducing  
your ISDN charges on the Cost Control page.  
To define Cost Control settings  
Click Cost Control on the Manual configuration menu. The DIVA LAN ISDN Modem displays the following  
page:  
Idle timer  
Each profile has its own idle timer. The idle timer controls how long a data call stays connected when no traffic  
is being sent or received. When the idle timer expires, the DIVA LAN ISDN Modem disconnects the call at the  
end of the next billing interval.  
If you set the idle timer to 0, the call will never be disconnected due to an absence of traffic, and you will have  
to disconnect the call manually. This can be useful for AO/DI connections.  
To set the idle timer  
1. On the Cost Control page, click the name of the profile you want to adjust the idle timer for. The DIVA  
LAN ISDN Modem displays the Connection profile parameters page.

2. Set the Idle timer.  
3. Click Finish.  
4. Click Save.  
5. Click Reset.  
Data call thresholds  
By defining data call thresholds, you are able to limit the total number of calls or total length of calls made by  
any one profile during a set period of time. This is especially useful as a safety measure if you have devices that  
may inadvertently generate a large number of calls or may stay connected indefinitely.  
The threshold monitoring interval is set in days. During this interval, the DIVA LAN ISDN Modem tracks the  
duration and number of calls each profile makes. You can set two different limits to watch for:  
• Maximum duration of calls: Sets the maximum number of hours a profile can be connected during the  
threshold monitoring interval. Range: 0 (disabled), 1 to (24 * number of days in the interval).  
• Maximum number of calls: Set the maximum number of calls a profile can make during the threshold  
monitoring interval. Range: 0 (disabled) to 1000  
If a profile exceeds either limit, all profiles are disabled. You must reset the DIVA LAN ISDN Modem to  
re-activate the profiles (or dial them manually to connect). Doing either also resets the threshold interval. (To  
determine if a profile has been disabled, click Connection Profiles on the Configuration main menu.)  
ISDN billing intervals  
A billing interval is the minimum amount of connection time your ISDN provider recognizes. For example,  
many ISDN providers use a one minute interval, which means you pay the same amount whether you are  
connected for ten seconds, or sixty seconds. Sometimes, two intervals are used, one for the first minute, and  
one for each subsequent minute.  
It is to your advantage to stay connected for the entire length of your billing interval. This helps avoid  
situations where a connection is established to transmit or receive a small amount of data, taken down, then  
immediately brought up again moments later.  
The DIVA LAN ISDN Modem has two timers that let you manage your billing intervals.  
• Initial Billing Interval: Sets the minimum amount of time that an ISDN B-channel will be enabled.  
• Recurring Billing Interval: Sets the minimum amount of time that an ISDN B-channel remains enabled  
after the Initial Billing Interval expires.  
These timers should be set to match the billing intervals used by your ISDN provider. For example, if your  
ISDN provider charges a flat fee for the first minute, and then bills every 40 seconds thereafter, you would set  
the intervals as follows.  
• Initial Billing Interval = 60 seconds  
• Recurring Billing Interval = 40 seconds  
This ensures that each time an ISDN B-channel is enabled, it stays active for at least 60 seconds. This avoids a  
situation where a B-channel is enabled only for 30 seconds, dropped, then enabled again a few seconds later. If  
a B-channel is up for more than 60 seconds, then the interval is reduced to 40 seconds.  
The billing interval timers work in conjunction with the idle timer. When the idle timer expires, the B-channel  
is dropped at the end of the next billing interval.

The bandwidth allocation protocol (BACP) works in conjunction with the MLPPP connection protocol to  
regulate usage of your ISDN line. The DIVA LAN ISDN Modem uses BACP to monitor incoming and  
outgoing traffic, and to open or close the second ISDN B-channel as the traffic volume warrants. This reduces  
your communications charges by ensuring that two ISDN channels are never active when one is sufficient.  
You customize how BACP opens and closes B-channels by setting the following parameters.  
• Delay for opening the 2nd B-channel: Sets the amount of time data traffic on the first ISDN B-channel  
must exceed the specified Threshold value, for BACP to bring up the second B-channel.  
• Threshold for opening the 2nd B-channel: Sets the percentage of total bandwidth on the first B-channel  
that must be exceeded.  
• Delay for closing the 2nd B-channel: Sets the amount of time data traffic on the first ISDN B-channel  
must be below the specified Threshold value, for BACP to drop the second B-channel.  
• Threshold for closing the 2nd B-channel: Sets the percentage of total bandwidth on the first B-channel  
that traffic must be below, for BACP to drop the second B-channel.  
The relationship between these parameters is best illustrated with an example. Assume the parameters are set  
as follows:  
• Delay for opening the 2nd B-channel: 5  
• Threshold for opening the 2nd B-channel: 50  
• Delay for closing the 2nd B-channel: 5  
• Threshold for closing the 2nd B-channel: 40  
When traffic on the first B-channel exceeds 32 kbps (50% of 64 kbps) for five seconds, BACP enables the  
second B-channel. The second B-channel remains active until traffic on the first B-channel falls below 25.6  
kbps (40% of 64 kbps).  
To configure BACP  
Each profile that uses BACP will have its own BACP settings. To configure BACP for a profile, do the  
following:  
1. On the Configuration main menu, click Connection Profiles.  
2. Click Edit for the profile you want to configure BACP for. You will see the following page.  
3. If you have not selected MLPPP + BACP as the Protocol, do so now.

Configuring AO/DI 63  
Configuring AO/DI  
AO/DI lets you maintain a permanent connection to the Internet or a corporate network, without tying up an  
expensive ISDN B-channel. AO/DI accomplishes this by using the ISDN D-channel to establish a  
low-bandwidth (9.6 kbps) connection with your ISP or corporate network. When incoming or outgoing traffic  
exceeds the capabilities of the D-channel, AO/DI automatically invokes one or more B-channels to handle the  
increased traffic.  
Some advantages of AO/DI include:  
• Makes maintaining a permanent connection to the Internet more cost effective. With such a connection,  
remote users can connect with the DIVA LAN ISDN Modem from any remote location that has Internet  
access. This eliminates the need to dial in via ISDN. (To make the connection permanent you must set the  
idle timer to 0. See page 59.)  
• Ideal solution for connecting to a remote corporate network, because low-bandwidth keep alive traffic can  
use the D-channel, instead of constantly bringing up a B-channel.  
You customize how AO/DI opens and closes B-channels by setting the following parameters.  
• Delay for opening the 1st B-channel: Sets the amount of time data traffic on the ISDN D-channel must  
exceed the specified Threshold value, for AO/DI to bring up the first B-channel.  
• Threshold for opening the 1st B-channel: Sets the percentage of total bandwidth on the D-channel that  
must be exceeded, for AO/DI to bring up the first B-channel.  
• Delay for closing the 1st B-channel: Sets the amount of time data traffic on the ISDN D-channel must be  
below the specified Threshold value, for AO/DI to drop the first B-channel.  
• Threshold for closing the 1st B-channel: Sets the percentage of total bandwidth on the D-channel that  
traffic must be below, for AO/DI to drop the first B-channel.  
• Delay for opening the 2nd B-channel: The amount of time data traffic on the first B-channel must  
exceed the specified Threshold value, for AO/DI to bring up the second B-channel.  
• Threshold for opening the 2nd B-channel: Sets the percentage of total bandwidth on the first B-channel  
that must be exceeded, for AO/DI to bring up the second B-channel.  
• Delay for closing the 2nd B-channel: Sets the amount of time data traffic on the first B-channel must be  
below the specified Threshold value, for AO/DI to drop the second B-channel.  
• Threshold for closing the 2nd B-channel: Sets the percentage of total bandwidth on the first B-channel  
that traffic must be below, for AO/DI to drop the second B-channel.  
• Mode: Determines ISDN line usage when AO/DI is enabled.  
• D-Channel Only: Data is only transferred on the D-channel.  
• Normal: Data is transferred on the D-channel, plus both B-channels if required.  
• Dial prefix: Specifies the prefix to dial when making a call. For example, 1 to call long distance, or 9 to  
obtain an external line  
• X.25 transmit queue threshold: Specifies the transmit queue threshold, in bytes, for X.25 on the  
D-channel. When queued data exceeds this limit, for the period of time specified for the parameter Delay  
for opening the 1st B-channel, the first B-channel is brought up. This parameter performs a similar  
function to Threshold for opening the 1st B-channel, and can be used concurrently with that parameter.

Configuring AO/DI 65  
X.25 on the D-channel  
During normal ISDN operation, the D-channel is used for signalling traffic purposes (call setup, call take  
down, caller ID, etc.) However, the full bandwidth of the D-channel is not needed for this. AO/DI takes  
advantage of the extra 9.6 bps that is available to establish an X.25 packet-switched connection to a remote site.  
Therefore, to take advantage of AO/DI, the remote site must support X.25 and you must properly configure the  
following X.25 settings on the DIVA LAN ISDN Modem.  
The following parameters should be set based on the values supplied by your ISP or remote corporate network.  
• Local DTE address: Sets the X.25 DTE address assigned to the DIVA LAN ISDN Modem. Specify  
up to 15 digits.  
• Maximum window size: Defines the maximum number of X.25 packets that can be outstanding (not  
acknowledged by the remote). When this number is reached, transmission is paused. Maximum  
window size can never be exceeded. If a larger window size is requested when the call is established,  
it is negotiated downward so that the Maximum window size is respected.  
• Default window size: The window size used when a X.25 call is made. This value cannot be larger  
than the value of Maximum window size.  
• Maximum packet size: The maximum size of an X.25 packet. Maximum packet size can never be  
exceeded. If a larger packet size is requested when the call is established, it will be negotiated down-  
ward so that the Maximum packet size is respected.  
• Default packet size: The packet size used when a X.25 call is made. This value cannot be larger than  
the value of Maximum packet size.  
• Number of VCs: Specify the number of two-way virtual circuits supported on your D-channel. The  
DIVA LAN ISDN Modem supports up to four VCs.  
• ISDN TEI type: Determines how TEI assignment takes place.  
• Dynamic: TEIs are dynamically assigned by the switch.  
• Shared: Enables TEI sharing. Some switches only make two TEIs available for an ISDN line.  
Therefore, enable this option if you need three dynamically assigned TEIs (two B and one D).  
This shares the TEI between channels B1 and D. Requires AO/DI.  
• Static: Lets you manually specify the TEI assignment for the D-channel.  
• Static TEI number: If static was selected for ISDN TEI type, enter the TEI number you want to  
assign to the D-channel.

Spoofing NetBIOS services 68  
Spoofing NetBIOS services  
The NetBIOS protocol is used by Windows 95/98/NT to support Microsoft Windows Network Neighborhood,  
the MAP NETWORK option in Windows Explorer, and various DOS-based networking commands (such as  
net use, net view, and net logon). To maintain these services, NetBIOS regularly exchanges bookkeeping  
messages between connected systems. This can cause increased ISDN charges as the line is brought up just to  
transfer these messages.  
The DIVA LAN ISDN Modem provides several options that let you choose the level of NetBIOS support you  
want to maintain.  
• All: The DIVA LAN ISDN Modem forwards all NetBIOS traffic to the remote site. No cost savings is  
achieved.  
• Intelligent: The DIVA LAN ISDN Modem spoofs (replies to without forwarding) all unnecessary traffic  
NetBIOS messages to reduce usage of the ISDN line. This option provides full support for all Network  
Neighborhood functions.  
• Minimal: The DIVA LAN ISDN Modem reduces NetBIOS traffic to a minimum. This options does not  
support Network Neighborhood functions. However, it does provide support for the MAP NETWORK  
option in Windows Explorer and DOS-based networking commands such as net use, net view, and net  
logon.  
• None: The DIVA LAN ISDN Modem discards all NetBIOS traffic. NetBIOS services are not supported  
across the ISDN link.

Data compression 69  
Data compression  
Data compression increases the effective throughput of a B-channel by encoding data so that fewer bits are  
required to represent it. Popular compression algorithms typically reduce the size of the data by 50 percent,  
effectively doubling the rate at which it is transmitted.  
However, not all types of data lend themselves to such high compression ratios. If you are transmitting ZIP  
files, JPG or GIF images, MPEG files, or other data that has already been storage-optimized, activating  
compression can have very little effect on throughput. This occurs because the compression algorithm can only  
achieve a small reduction in file size, which is offset by the processing overhead required for the sender to  
compress the file and the receiver to uncompress it. Therefore, you should determine if the traffic on your link  
is suitable for compression before you enable it.  
The compression algorithm used is automatically negotiated by the DIVA LAN ISDN Modem and the remote  
site when the connection is established. The DIVA LAN ISDN Modem supports most popular compression  
standards, including: Ascend, MPPP, MS-STAC, STAC1, and STAC3.  
You can enable/disable compression for each connection profile individually.  
1. On the Configuration main menu, click Connection Profiles.  
2. Click Edit for the profile you want to configure compression for.

Restricting analog calls 71  
Restricting analog calls  
Generally, most of the activity on the ISDN line will be created by data traffic. That is why the most of the  
settings in this section are targeted at data calls. However, in some cases, you may want to place some  
restrictions on analog use of the ISDN line.  
Each phone port has a type of calls setting which you can use for cost control purposes. It allows you to restrict  
traffic as follows:  
• allow incoming calls only  
• allow outgoing calls only  
• allow all calls  
• do not allow any calls  
To restrict analog calls  
1. On the Manual Configuration menu, click ISDN and phone ports. The DIVA LAN ISDN Modem displays  
the ISDN parameters page.  
2. Select the phone port you want to restrict calls on. The DIVA LAN ISDN Modem displays the ISDN

Network address translation 78  
Network address translation  
The DIVA LAN ISDN Modem uses network address translation (NAT) to “hide” the local LAN it creates from  
all external resources. The benefits of this are the ability for all connected computers to access the Internet  
using one Internet address and ISP account. For example, when communicating with the Internet, these four  
computers share the dynamically assigned address 222.182.22.39.

NAT operates transparently, translating internal addresses to a single external one for all data traffic. There is  
no effect on throughput.  
Most applications will work with NAT. For a list of applications that have been tested by Eicon Technology, see  
the release notes on the DIVA LAN ISDN Modem CD.  
NAT is enabled by default, and it is recommended that you do not turn it off unless you have a specific  
requirement to do so.  
(For more information on IP addressing see “About IP addresses” on page 120.)  
Security benefits  
An additional benefit of NAT is increased network security. Like a firewall, NAT restricts access to the  
computers that reside on the local LAN. By default, no computer on the internal LAN is visible to the external  
network the DIVA LAN ISDN Modem is connected to. This applies to the Internet, as well as a corporate  
network. Computers on the internal network cannot act as FTP or web servers, nor can they share their drives  
using Windows Network Neighborhood. These security features can be weakened if you use NAT static  
mappings.  
NAT static mappings  
For those cases where you want to create an FTP or web server, or need a computer on the internal LAN to be  
visible to the external network, the DIVA LAN ISDN Modem provides a solution. You can define NAT static  
mappings.  
How it works  
NAT static mappings allow you to designate specific computers on the internal LAN to receive certain  
incoming network traffic. For example, you could designate a computer to receive all incoming HTTP traffic,  
essentially allowing it to function as a web server. However, the actual IP address of this computer is still  
hidden by NAT. Therefore, remote users must specify the address of the DIVA LAN ISDN Modem to gain  
access to the web server.  
When you create a NAT static mapping, the DIVA LAN ISDN Modem routes all traffic for the protocol you  
specify to the designated computer. This includes traffic normally handled by the DIVA LAN ISDN Modem  
itself. This leads to the following restrictions:  
• Remote access to the configuration interfaces on the DIVA LAN ISDN Modem via the ISDN link can be  
disrupted. For example, if you designate a computer to receive HTTP traffic, remote access to the web  
configuration interface will be disrupted. Local access via Ethernet will still be possible however.  
• Only one computer on the internal LAN can be designated to receive the traffic for a specific protocol.  
This means, for example, you can cannot create multiple web servers or FTP servers.

Chapter Six: Security  
Network address translation 79  
Default NAT server  
When the DIVA LAN ISDN Modem receives incoming datagrams containing protocols it does not handle, it  
discards them. For example, if an incoming datagram contains an FTP request and no FTP server has been  
defined using a static mapping, the data is discarded.  
In some cases, you may want to forward these datagrams to a specific computer. The DIVA LAN ISDN  
Modem calls this computer, the default NAT server.  
To define a default NAT server, enter the IP address of the device that should receive these datagrams into the  
Default NAT server parameter on the IP Parameters panel (see page 80).  
Note The DIVA LAN ISDN Modem handles traffic with the following protocols: HTTP, Telnet, TFTP, ECHO  
(UDP port 7), and SNMP. Only traffic that does not contain these protocols will be forwarded to the default  
NAT server. To forward these protocols you must define a NAT static mapping for each one.  
Running a web or FTP server  
Two of the most common reasons to use NAT static mappings are to run a web server or FTP server on a  
computer connected to the DIVA LAN ISDN Modem.  
Use the following diagram as a reference as you examine the NAT mapping examples that follow:

Configuring a NAT static mapping for a web server  
Web traffic is carried on TCP port 80. Therefore, the following NAT mapping is required:  
To access the web server, a remote computer uses the URL: HTTP://223.132.212.39/  
The DIVA LAN ISDN Modem forwards all web traffic to the appropriate computer on the internal LAN.  
Note Setting up a web server disables remote access (via the ISDN line) to the DIVA LAN ISDN Modem web  
interface. Local computers can still log in.  
Configuring a NAT mapping for an FTP server  
FTP traffic is carried on TCP ports 20 and 21. Therefore, the following two NAT mappings are required:

Remote management 81  
Remote management  
By default, the DIVA LAN ISDN Modem does not allow remote devices to access its configuration interfaces  
via the ISDN link. This prevents unauthorized tampering when the DIVA LAN ISDN Modem has dialed out  
and is connected to the Internet or a remote corporate network.  
To accomplish this security, all incoming HTTP and Telnet traffic on the ISDN line is automatically dropped.  
This effectively blocks remote computers from using the web-based interface, as well as the CLI (via Telnet).  
This does not affect traffic on the local LAN created by the DIVA LAN ISDN Modem. Therefore, if the local  
LAN is connected to other networks, these computers will have access to the DIVA LAN ISDN Modem.

Incoming data calls 83  
Incoming data calls  
By default, the DIVA LAN ISDN Modem refuses all incoming ISDN data calls. This effectively shuts the door  
on unauthorized systems dialing-in. (Voice calls are not blocked by this setting.)  
When support for incoming data calls is activated and an incoming call is received, the DIVA LAN ISDN  
Modem compares the user name and password supplied by the remote site against the remote user name and  
remote password configured for each connection profile. If a match is found, the call is accepted. Otherwise,  
the call is rejected. Therefore, to accept incoming data calls you must define call authentication settings for the  
appropriate profile (as explained in the steps below).  
Note Since the DIVA LAN ISDN Modem checks the ISP profile first, if both profiles have the same remote user  
name, the incoming call will always connect with the ISP profile.  
Incoming data calls can only be received if there is an available B-channel. To keep a free channel, you must  
use PPP (or V.120) for your existing connection. If you are using MLPPP, you will only be able to receive  
incoming voice calls if no data call is active. See “Choose a connection protocol” on page 20 for more  
information.  
Note When you enable callback support (page 88) using the web configuration interface, the DIVA LAN ISDN  
Modem automatically enables support for incoming data calls.  
Incoming calls and IP addressing  
For an incoming call to successfully connect, you must define a proper IP addressing scheme for the profile  
that will handle the connection. This means setting the following three parameters: IP address, Subnet mask,  
and Remote IP address.  
Generally, when you configure the DIVA LAN ISDN Modem to connect to the Internet, you set the IP address  
parameter to 0.0.0.0, which means that the address will be dynamically assigned by the ISP when the profile  
connects. When you receive an incoming call however, it may be the responsibility of the DIVA LAN ISDN  
Modem to assign an IP address to the caller. In this case, the static address you set for Remote IP address  
would be adopted by the caller.  
The following diagram illustrates the effects of potential addressing schemes. (The subnet mask is omitted  
from this discussion, but should be set to match the IP address. See“About IP addresses” on page 120 for more  
information on masks.)

Incoming data calls 84  
Notes on the diagram  
1. The DIVA LAN ISDN Modem provides an IP address to the remote computer.  
2. Both the DIVA LAN ISDN Modem and the remote computer have their own fixed IP addresses so no  
assignments are made.  
3. Both the DIVA LAN ISDN Modem and the remote computer have their own fixed IP addresses AND have  
specified remote addresses. This means they will only be able to connect if the remote addresses match  
the IP addresses of the other device.  
4. The remote computer provides an IP address to the DIVA LAN ISDN Modem.  
5. The remote computer has no IP address and the DIVA LAN ISDN Modem is not configured to supply one.  
6. The DIVA LAN ISDN Modem has no IP address and the remote computer is not configured to supply one.  
7. Neither device has an IP address and neither is configured to supply one.

Call authentication 87  
Call authentication  
Call authentication enables ISDN devices, like the DIVA LAN ISDN Modem, to validate the identity of the  
device at the other end of the line. Authentication works through the exchange of usernames and passwords. It  
can be one-way (either the caller gets validated or the callee gets validated) or two-way (both sides validate  
each other).  
Generally, authentication is one-way, with the caller getting validated. For example:  
• When the DIVA LAN ISDN Modem calls an ISP or a corporate network, it will be authenticated (i.e., it  
must supply a username and password to log on).  
• When a remote computer calls the DIVA LAN ISDN Modem, it will be authenticated (i.e., it must supply  
a username and password for the call to be accepted).  
To successfully use call authentication it is important that both devices are configured to support the same  
authentication options.  
To set up call authentication  
1. On the Configuration main menu, click Connection Profiles.  
2. Click Edit for the profile you want to configure.  
3. Click Authentication on the menu bar. You will see the following page:  
4. Specify the Local username and Local password this profile will send to the remote site during the  
authentication process. For example, the ISP profile uses these values to log on to your ISP account.  
Note Local username and Local password are case-sensitive.  
5. Specify the type of password the DIVA LAN ISDN Modem will send to the remote: encrypted or any  
(unchecked). If the remote is not using the same type of encryption, the call will be rejected.  
Note This setting applies to outgoing calls only.  
6. Enable Always authenticate the remote if you want the DIVA LAN ISDN Modem to ask the remote to  
identify itself with a username and password. The DIVA LAN ISDN Modem will compare the values the  
remote sends against the settings you make for Remote username and Remote password. Remote  
username and Remote password are case-sensitive.  
Note This setting applies to outgoing calls only. The DIVA LAN ISDN Modem always authenticates the  
remote when receiving an incoming call.

Callback 88  
Callback  
Callback is another effective method to control access to the DIVA LAN ISDN Modem. When callback is  
enabled, the DIVA LAN ISDN Modem functions as a callback client, and the remote site being called  
functions as a callback server.  
The client calls the server, the connection is dropped or disconnected, then waits for the server to call back to  
re-establish the connection. While waiting for the server to call back, the DIVA LAN ISDN Modem may  
accept incoming calls that are not from the server. To ensure that only calls from the server are accepted you  
can use call authentication (set the always authenticate remote option as shown on page 87) to validate the  
incoming call.  
The DIVA LAN ISDN Modem can only function as a callback client.  
Note When you enable callback using the web configuration interface, the DIVA LAN ISDN Modem  
automatically enables support for incoming data calls (page 83).  
Callback modes  
Two callback modes are available. Each provides different features. For callback to work, both client and  
server must use the same mode.  
Callback control protocol  
This is a Microsoft-developed solution. It is used by NT4, and devices from Cisco, Ascend, and other vendors.  
NCP enables you to specify a time delay before the server calls back, and supports both the user specified and  
administrator specified options.  
ISDN callback  
Unlike the callback control protocol, the server does not answer the initial call from the DIVA LAN ISDN  
Modem when using ISDN callback mode. Therefore, there is no charge for the call. This can be advantageous  
if you are making a lot of calls without a flat-rate package, or are making long distance calls.  
ISDN modem only works with Cisco IOS. It uses caller ID information to return the call. Therefore, caller ID  
must be enable on your line to use this mode.  
Callback options  
Two callback options are available: user specified and administrator specified.  
User specified  
This option requires that the DIVA LAN ISDN Modem supply the server with the callback number to use. If  
the server is on a PBX, or must dial long distance, you may need to include appropriate dialing prefixes.  
Contact the system administrator of the server to determine the exact requirements.  
The main advantage of this option is that if you change the DIVA LAN ISDN Modem’s ISDN phone numbers,  
you do not have to inform the server, since you supply the phone number with each call.  
Administrator specified  
With this option, the DIVA LAN ISDN Modem does not supply the server with a number to dial. Instead, the  
remote identifies the DIVA LAN ISDN Modem by its caller ID or information supplied during call  
authentication. The server then consults a pre-configured table to determine the number to dial.  
The main advantage of this option is centralized security. The server maintains a list of all valid clients, with  
their physical phone numbers and security information.  
Note It may not always be possible to support an MLPPP connection with the administrator specified option.  
The reason for this is that the server will only have one number configured for callback. When it tries to  
establish the second channel, it gets a busy signal. The solution is to use user specified, and send the server the  
two numbers that are required.

Chapter Six: Security  
Callback 89  
Delay before host calls back  
This option is only supported by the callback control protocol. It allows you to specify the amount of time the  
server waits before calling back. The DIVA LAN ISDN Modem proposes the delay during callback  
negotiation. The server can either accept or reject it.  
Timeout waiting for callback  
Sets the amount of time the DIVA LAN ISDN Modem waits for the server to call back. During this time, the  
DIVA LAN ISDN Modem may accept calls that are not from the callback server unless you use call  
authentication (set the always authenticate remote option as shown on page 87) to validate the incoming call.  
To set up callback  
Note When you enable callback using the web configuration interface, the DIVA LAN ISDN Modem  
automatically enables support for incoming data calls (page 83).  
1. On the Configuration main menu, click Connection Profiles.  
2. Click Edit for the profile you want to configure callback for.

Manual dialing 90  
Manual dialing  
The DIVA LAN ISDN Modem automatically establishes the ISDN link whenever there is outgoing data traffic.  
There may be certain situations where this is not desirable and you will want to have manual control of ISDN  
usage. The manual dialing option gives you this control.  
Each profile can be configured to use manual dialing only. If you enable this option and password protect the  
DIVA LAN ISDN Modem, you effectively put ISDN access under direct manual control of authorized users.

Call bumping 95  
Call bumping  
Call bumping, more formally known as dynamic bandwidth allocation (DBA), allows you to share the ISDN  
line between data and analog calls. This enables you to send and receive faxes, or make phone calls, while at  
the same time downloading data from the Internet with your computers.  
How it works  
When you enable call bumping, incoming or outgoing analog calls can bump one B-channel of an active data  
connection to gain access to the ISDN line. This ensures that a line is almost always available for your voice or  
fax calls.  
A sample call bumping scenario  
• A data connection using MLPPP is in progress. It is currently using both ISDN channels to transfer a large  
database (both B-channel LEDs are green).  
• Suddenly, that important phone call you were expecting arrives. As soon as the phone rings, the data  
connection automatically drops one of the ISDN B-channels, reducing throughput from 128 kbps to 64  
kbps, and the voice call is connected. One of the B-channel LEDs will change from green to orange,  
indicating a voice call is active.  
• When the call is done you hang up the phone. Automatically, the data connection re-establishes the  
second B-channel and brings throughput back up to 128 kbps.  
Call bumping works in the same manner if you pick up the phone and place an outgoing call.  
Requirements  
To support call bumping:  
• you must be using Multilink PPP (MLPPP), as your connection protocol. See the section “Choose a  
connection protocol” on page 20 for more information on MLPPP.  
• your ISDN line must support the Call Waiting supplementary service.  
To enable call bumping  
1. On the Manual Configuration menu, click ISDN and phone ports. The DIVA LAN ISDN Modem displays  
the ISDN line parameters page.  
2. Click the Enable Call Bumping check box.

Restricting analog calls 96  
Restricting analog calls  
Generally, most of the activity on the ISDN line will be created by data traffic. That is why the most of the  
settings in this section are targeted at data calls. However, in some cases, you may want to place some  
restrictions on analog use of the ISDN line.  
Each phone port has a type of calls setting which you can use for cost control purposes. It allows you to restrict  
traffic as follows:  
• allow incoming calls only  
• allow outgoing calls only  
• allow all calls  
• do not allow any calls  
To restrict analog calls  
1. On the Manual Configuration menu, click ISDN and phone ports. The DIVA LAN ISDN Modem displays

Supplementary services  
The supplementary services described in this section only work if they are supported by your ISDN service  
provider and if they are enabled on your ISDN line. Contact your ISDN service provider for more information  
on the calling features that are available in your area and the provisioning of your ISDN connection.  
If you attempt to use a calling feature that is not available to you, you will hear four beeps (called the service  
failure tone) through your telephone handset.  
• Call Forwarding  
• Call Waiting  
• VoiceMail  
• Caller ID  
• Three-way Conference Calling  
• Call Transfer  
Note If you did not use EZ-ISDN or IOC to order your line, verify that the DIVA LAN ISDN Modem's default  
settings are compatible with those of your ISDN provider before using this feature. See “Feature Key values”  
on page 99 for more information.  
Note To use Calling Features, your ISDN line must support the following: Additional Call Offering (ACO)  
and Flexible Calling (FC). If you ordered your ISDN line using the proper EZ-ISDN code, you should have  
access to these features.  
Note Calling Features are accessed via codes (for example, *72). The codes you use will differ depending on  
your ISDN Service Provider. Contact your ISDN Service Provider for more information.  
To enable supplementary services  
1. On the Manual Configuration menu, click ISDN and phone ports. The DIVA LAN ISDN Modem displays  
the ISDN phone line parameters page.  
2. In the Define settings for box, choose the phone port you want to enable calling features for. DIVA LAN

Call Forwarding  
Call Forwarding automatically transfers incoming calls to wherever you are so you never miss a customer call  
even when you’re away from your home office. Call Forwarding is accessed by dialing a simple code (e.g.,  
72#<forward number>). Not all ISDN Service Providers use the same dial codes. Ask your ISDN Service  
Provider for the codes you should use.  
Note Some ISDN Service Providers use *70 to activate Call Forwarding. If you press *70, but call forwarding  
does not get activated, try using **70. Contact your ISDN Service Provider if problems persist.

Supplementary services 98  
If your ISDN service conforms to EZ-ISDN 1A or EZ-ISDN 3A, you will also have VoiceMail. If the number  
to which you have forwarded your calls is busy or does not answer, the call will automatically be forwarded to  
your VoiceMail. With VoiceMail, the DIVA LAN ISDN Modem also supports Visual Message Waiting  
Indicator.  
Call Forwarding supports Reminder Ring. Reminder Ring causes your telephone to ring once (for about ½ a  
second) whenever it forwards a call. If your phone has Caller ID (see “Caller ID” on page 98), it will display  
details of the forwarded call.  
Call Waiting  
Call Waiting alerts you to an incoming call when you're already on the phone. You can put one call on hold  
while you accept another, so you'll never miss a customer call. It works as follows:  
If you receive a second call while on a call, a beep sounds. To answer the second call, press the Flash/Link  
button. The first call is then put on hold and the second call is answered. You can press the Flash/Link button to  
toggle between the two calls.  
The call waiting beep is repeated 10 seconds later if the second incoming call is not answered.  
Call Waiting can be disabled by using a code before dialing a number (e.g., *70). Not all ISDN Service  
Providers use the same dial codes. Ask your ISDN Service Provider for the codes you should use.  
If your phone is a Type II phone with Caller ID, the phone will display the number of the second incoming call  
(the call waiting).  
If you hang up while a call is on hold, the phone will ring for 30 seconds before disconnecting the call. It is  
limited to 30 seconds as charges may apply for the call on hold.  
VoiceMail  
VoiceMail allows you to receive voice messages when you cannot answer a call (for example you are away  
from your desk, or if your line is busy with a voice or data call). All unanswered callers will be forwarded to  
your VoiceMail box, where they can leave a voice message.  
VoiceMail supports Visual Message Waiting. With Visual Message Waiting, a flashing light on the phone set  
indicates that there is a new message in your voice mail box. This feature requires a “Class R” phone with a  
Message Light.  
Caller ID  
Caller ID lets you know who's calling before you answer, so you can decide how to handle the call.  
Caller ID also works with Call Waiting, by displaying the number of the second incoming call (a Type II Caller  
ID phone is required), and with Call Forwarding by displaying the details of the forwarded call.  
Three-way Conference Calling  
Three-way Conference Calling lets you speak with up to two people at the same time so you can accomplish  
more with fewer phone calls. It works as follows:  
While connected to the first person, press the Flash/Link button (this places the first party on hold). Dial the  
second person's number. After the second person answers, press the Flash/Link button. You and the two other  
people will all be connected. If you want to drop the last party added to the call, press the Flash/Link button.  
Service Failure Tone  
If get a service failure tone every time you start a conference call, and you did not use EZ-ISDN or ISDN codes  
when ordering your line, check the assignment of the Three-way Conference feature key (See “Feature Key  
values” on page 99).

Call Transfer  
Call Transfer allows you to disconnect from a Three-Way Conference call and leave the other two people  
connected. It works as follows: Establish a Three-Way call as described in the section above. Hang up. The  
other two people remain connected.  
Feature Key values  
To access calling features, the DIVA LAN ISDN Modem supplies the ISDN switch with certain codes called  
Feature Keys. Not all ISDN providers use the same Feature Keys (unless you are using an EZ-ISDN or IOC  
line). Ask your ISDN service provider for a list of Feature Key values that your DIVA LAN ISDN Modem  
should use.  
Note Some ISDN providers allow you to specify which Feature Key values you want to use. If this is the case,  
you can supply the DIVA LAN ISDN Modem default values, and no further configuration is necessary. If your  
ISDN provider supports user supplied Feature Key values, supply them with the values in the following table.  
The default values for the DIVA LAN ISDN Modem are as follows:  
Feature Key  
Value  
60  
3-Way Conference  
Call Drop  
62  
Message Waiting Indicator  
63  
If the Feature Key values supplied by your ISDN provider do not match, you must configure your DIVA LAN  
ISDN Modem to use the proper values. The Feature Key values can only be changed via the CLI. See Chapter  
Ten for details on how to use the CLI.

Using the corporate connection 107  
Using the corporate connection  
The DIVA LAN ISDN Modem automatically dials out and establishes the ISDN link to your corporate network  
as required. You simply launch the applications you use to do your work, such as a web browser or e-mail  
program, and you are automatically connected.  
You can also establish your connections manually, dialing and hanging up connections as you see fit. See page  
45 for details.  
How long will the line stay connected?  
By default, the DIVA LAN ISDN Modem will stay connected until the line has been idle for two minutes. To  
adjust this setting, see “The Cost Control page” on page 59.  
Support for Microsoft Network Neighborhood  
If you are connecting to an Microsoft NT network, see “Spoofing NetBIOS services” on page 68 for  
information on supporting Network Neighborhood functions.  
NetBIOS name resolution  
If you use Microsoft networking, then you will need to be able to resolve NetBIOS names to IP addresses. If  
you allow the Microsoft WINS client to use DNS as a method of resolving names (Windows NT), then it could  
result in persistent ISDN calls being generated. In general, it is recommended that you make entries in the  
LMHOSTS file of each computer connected to the DIVA LAN ISDN Modem to resolve NetBIOS names.  
Consult the Microsoft documentation for your operating system for more information on how to do this.  
Timeouts  
To save communications charges, the DIVA LAN ISDN Modem will drop the ISDN line when it is idle.  
Although this may not cause problems for most applications, it can cause difficulties for the corporate server  
you are connected to. If the server implements TCP keep alives, then the server will hang up your TCP/IP  
session if the ISDN line is down when the keep alives are sent. Thus, when the DIVA LAN ISDN Modem  
reconnects (i.e., the client sends more data), the session will have been aborted.  
Dynamic IP addressing  
If the corporate network uses dynamic IP address assignment, it is possible that each time the DIVA LAN  
ISDN Modem connects it will be given a different IP address. This can cause problems for some session-based  
applications when the DIVA LAN ISDN Modem drops the ISDN link due to inactivity. When the link is  
re-established, the server has given the DIVA LAN ISDN Modem a new IP address. When the application  
attempts to continue using the previous session, it is refused because of the address change.  
Although applications may not themselves timeout when the DIVA LAN ISDN Modem drops the line due to  
inactivity, the IP stack on the corporate server you are connected to may.

Installing on an existing LAN 112  
Installing on an existing LAN  
Installing the DIVA LAN ISDN Modem on an existing LAN can be extremely simple, or quite challenging,  
depending on the complexity of your existing LAN setup. To help you successfully integrate the DIVA LAN  
ISDN Modem into your setup, this section presents an installation strategy that should work in the majority of  
cases. However, due to the wide range of networking equipment and topologies that are in use worldwide, your  
configuration needs may fall outside the strategy presented here. In this case, you should contact your network  
administrator, or other support person to help you with your installation.  
Using Modem Monitor  
Modem Monitor greatly simplifies the task of installing the DIVA LAN ISDN Modem on a LAN. If at least  
one of the computers on your LAN is running Windows 95/98/NT, follow the instructions in Chapter Two to  
install and configure the DIVA LAN ISDN Modem. However, make the following exceptions:  
• Instead of connecting the DIVA LAN ISDN Modem directly to your computers, connect it to the LAN.  
Do this by connecting any one of the DIVA LAN ISDN Modem’s ETHERNET ports to a port on your  
LAN hub.  
If your hub has a cross-over switch or cascade port, you can use the supplied blue Ethernet cable to make this  
connection. If not, you will need a special cross-over Ethernet cable to make this connection.  
Try connecting the supplied blue cable to the hub, if the green Ethernet light on the DIVA LAN ISDN  
Modem does not light up, you need a special cross-over cable.  
• Install the Modem Monitor software on a Windows 95/98/NT computer that is connected to the LAN.  
Modem Monitor will automatically detect the DIVA LAN ISDN Modem and let you adjust its IP settings  
for proper operation on the LAN.  
Once installation is complete, you may need to adjust the configuration settings of the computers on your  
LAN. See “Adjusting configuration settings on the LAN” on page 114 for complete details.  
Manual installation  
Follow these steps to install the DIVA LAN ISDN Modem on a LAN if you are unable to run Modem Monitor  
on a computer on your network.  
1. Determine how IP addresses are assigned on the LAN.  
• Static: Each computer on your LAN has a fixed address. If this is the case, then determine the IP  
address and subnet mask that will be assigned to the DIVA LAN ISDN Modem.  
• Dynamic: Addresses are assigned by a DHCP server (such as a Windows NT server).  
It is recommended that before you install the DIVA LAN ISDN Modem on your LAN, you should install  
and configure it for use with a single non-networked computer. This lets you verify that your ISDN line is  
functioning and that you are able to successfully communicate with the DIVA LAN ISDN Modem.  
2. Disconnect a computer from your LAN.  
3. Follow the instructions in Chapter Two to install and configure the DIVA LAN ISDN Modem. Pay  
particular attention to section “Verify the configuration of your computers” on page 18. If you need to  
change the settings of your computer, make sure you record the existing settings before you change them.  
4. Once installation and configuration are complete, confirm that your ISDN line works and that you have  
access to the Internet.  
5. Start the Web-based configuration interface.

6. Click LAN on the Manual Configuration menu. The DIVA LAN ISDN Modem displays the LAN  
parameters page.  
7. Set the IP address to a free address on your LAN. If your LAN uses dynamic addressing (DHCP server)  
make sure that the address you choose is outside the range of dynamically assigned ones, or that you  
reserve the address. For background information on IP addresses, see “About IP addresses” on page 120.  
8. Set the Subnet mask according to the requirements of your LAN.  
9. Click Save. Do not reset the DIVA LAN ISDN Modem.  
By default, the DIVA LAN ISDN Modem is configured to act as a DHCP server. If a computer on the LAN  
is already providing this function (such as a Windows NT server), you need to disable this feature on the  
DIVA LAN ISDN Modem.  
10. Click IP on the Manual Configuration menu.  
11. Click DHCP. The DIVA LAN ISDN Modem displays the LAN Parameters page.  
12. Uncheck the DHCP server enabled option.

Modem does not light up, you need a special cross-over cable.  
17. Press the Reset button on the back of the DIVA LAN ISDN Modem.  
18. Restore your computer’s network configuration settings and reconnect it to the LAN.  
19. Start your Web browser and enter the new IP address you assigned to the DIVA LAN ISDN Modem. Your  
browser should display the Log In page.  
20. You may need to adjust the configuration settings of the computers on your LAN. See “Adjusting  
configuration settings on the LAN” on page 114 for complete details.  
Adjusting configuration settings on the LAN  
Depending on your setup, you may have to adjust configuration settings on your computers in order to  
communicate with the DIVA LAN ISDN Modem. Due to the diversity of networking equipment and  
topologies, this section can only cover several of the most common setups. If you setup is more complex,  
contact your network administrator, or other support person to help you with your installation.  
If your LAN uses static addressing  
Configure TCP/IP on each computer that will communicate with the DIVA LAN ISDN Modem as follows:  
• Set Default Gateway to the address of the DIVA LAN ISDN Modem.  
• Set DNS Server to the address of the DIVA LAN ISDN Modem.  
If your LAN has a DHCP server  
Configure your DHCP server to return the address of the DIVA LAN ISDN Modem as the Default Gateway  
and DNS Server to all clients.  
If your LAN has a router  
If you have a router on your LAN, it is likely configured as the default gateway for your computers. In this  
case, you will need to configure the routing table on your router to re-direct the appropriate traffic to the DIVA  
LAN ISDN Modem. And add a route on the DIVA LAN ISDN Modem to direct appropriate traffic to the  
router.  
Consider the following example:

Creating a virtual private network 116  
Creating a virtual private network  
A virtual private network (VPN) is an interconnection between two networks that uses the PPTP  
(point-to-point tunneling protocol). By using the Internet to transport data, a VPN can eliminate long distance  
charges associated with traditional dial-up solutions. And, since PPTP provides a secure connection, network  
security is not compromised.

Concurrent Internet and Intranet connections 119  
Concurrent Internet and Intranet connections  
The DIVA LAN ISDN Modem can support both an Internet connection and an intranet connection to your  
corporate network. This section explains how to install and configure such a setup.  
Selecting a connections protocol  
One of the primary considerations is choice of connection protocol. If you want to have both connections active  
at the same time, you must assign PPP to each connection. The reason for this is that any MLPPP-related  
protocol reserves both ISDN channels for its exclusive use, even if they are not active. Therefore, the only way  
to share the two ISDN channels between two data connections is to use PPP for each.  
Defining routes  
If you have two active connections, it is important to define routes so that the DIVA LAN ISDN Modem can  
send data to the proper connection. In most cases, you will want to send certain specific traffic to your  
corporate network, and route all other traffic to the Internet.  
For a complete discussion of routing issues, see “IP routes” on page 120.  
Installation and configuration procedure  
1. Use the Internet wizard, as described in Chapter 2, to define your Internet connection.  
2. The Internet wizard will automatically add a default route to the routing table. The default route is defined  
as 0.0.0.0 with a mask of 0. This is a catch-all route. Any traffic which does not match any other route,  
will match the default route, and thus be sent to the Internet.  
3. Next, create a connection to your corporate network as described in Chapter Eight.  
• Choose PPP as the connection protocol.  
• When you reach the routing table, you should configure it as outlined in the section “Multiple  
connections” on page 124.  
4. You should now be able to use both connections.

IP routes 120  
IP routes  
This section provides background information on why IP routes are needed and explains how to define them.  
However, before you can understand routing, you must be familiar with IP addressing and how the DIVA LAN  
ISDN Modem assigns them.  
About IP addresses  
IP addresses identify the computers (and other devices) on an IP network. Each address is composed of 32 bits.  
To make things easier to understand, addresses are written out as four decimal numbers separated by dots. The  
numbers can range in value from 0 to 255. For example: 192.168.1.1 or 222.182.22.39  
Using masks  
IP addresses are composed of two parts: the network address and the host address. A host is any computer (or  
other device) on a network that is capable of transmitting or receiving data. To determine which portion of the  
address identifies the network and which portion identifies a host, a mask is used.  
Masks are specified in bits. A logical bitwise AND operation is performed between the address and the mask to  
extract the network address. To simplify, consider that each of the four decimal numbers that make up an  
address is represented by 8 bits. This leads to the following network addresses and their corresponding masks:  
Mask  
Mask  
Source  
Extracted  
(# of bits)  
(in decimal)  
IP address  
network address  
8
255.0.0.0  
222.182.22.39  
222.182.22.39  
222.182.22.39  
222.182.22.39  
222.0.0.0

32  
255.255.0.0

222.182.22.39  
255.255.255.0  
255.255.255.255  
This table also illustrates how the mask is used to extract the network address for a given source address. Note  
that when the mask is 32 bits, the extracted address is identical to the source address, and refers to a single host  
computer rather than a network.  
Static vs. dynamic addresses  
IP addresses can be either dynamic or static. Static addresses are fixed, and must be changed manually. They  
are used by computers that are permanently connected to the Internet (a web server, for example), and  
sometimes by computers on a LAN.  
Dynamic addresses can change. They are assigned using a special protocol such as DHCP or PPP (IPCP). For  
example, when connecting to the Internet, the IP address assigned to the DIVA LAN ISDN Modem by your  
ISP is usually dynamic, assigned by PPP (IPCP). It changes each time the DIVA LAN ISDN Modem connects.  
The DIVA LAN ISDN Modem and IP addresses  
The DIVA LAN ISDN Modem can have up to three IP addresses assigned to it. One address in used on the  
internal LAN it creates. The other two are used to communicate externally with remote sites.  
Internal LAN addresses  
By default, the DIVA LAN ISDN Modem is configured to act as a DHCP server. This means it is responsible  
for assigning IP addresses to each computer connected to it. To receive an address, each computer must be  
configured to obtain their IP addresses automatically from a DHCP server (see Chapter Nine).

DIVA LAN ISDN Modem  
By default, the DIVA LAN ISDN Modem uses the mask 255.255.255.0 when assigning addresses. This means  
that the network portion of the address is: 192.168.1.0  
Note that the DIVA LAN ISDN Modem has its own address on the LAN: 192.168.1.1  
External addresses  
When the DIVA LAN ISDN Modem establishes a connection to a remote site, it needs to be identified with an  
IP address. This address is associated with the profile making the connection. Since, two profiles are supported,  
two IP addresses are required.  
Generally, these external addresses are dynamic, and are automatically negotiated when the DIVA LAN ISDN  
Modem connects with the remote site. For example, when establishing a link with an ISP, the ISP will  
generally assigns an IP address to the DIVA LAN ISDN Modem. This address will change each time the DIVA  
LAN ISDN Modem reconnects.

IP routes 123  
Why routes are needed  
Data on an IP network is carried in small packages called datagrams. Each datagram contains the IP address of  
its source and destination. In order to send datagrams to their proper destination, the DIVA LAN ISDN Modem  
requires a list of destinations and the addresses that are associated with it. This information is stored in a route.  
Since more than one route is generally required, they are grouped together in a routing table. Each time the  
DIVA LAN ISDN Modem sends or received a datagram, it consults the routing table to determine the target  
destination for the datagram.

Routes  
Route 1 = 0.0.0.0 with a mask of 0. Assigned to Internet connection.  
Since there is only one destination for outgoing data (the Internet), only one route is required. This route needs  
to match all addresses. The special address 0.0.0.0 does this. The same would be true for a Corporate  
connection. If you want to route all data to the corporate network, specify a single route using the special  
address 0.0.0.0.  
There can be only one default route on the DIVA LAN ISDN Modem. The default route always uses the special  
address 0.0.0.0.

This scenario requires three routes:  
Route 3 is used to route traffic to the Corporate network (201.163.0.0). It is assigned to the Corporate  
connection.  
Notice that two subnetworks are directly connected to the Corporate network. Since one of these subnetworks  
has the same network address (201.163), traffic addressed to users on this subnet will be properly routed.  
Route 2 is required to send traffic to the second subnet (215.199.99.1). It is assigned to the Corporate  
connection.  
Route 1 is the default route. It is assigned to the Internet connection. It matches any address. Therefore, any  
traffic that is not routed by Route 2 or 3 is routed by Route 1 to the Internet.

Routing on the local LAN  
The DIVA LAN ISDN Modem lets you create your own local area network. In some instances, this network, or  
the DIVA LAN ISDN Modem itself, will be connected to another network via a bridge or router. Consider this  
scenario, which adds another LAN to the previously discussed example:

Route 4 = 150.150.0.0 with a mask of 16. Assigned to the LAN interface. Gateway address is 192.168.1.5  
Assuming that RIP (discussed in the next section), is not being used on the LAN, this scenario requires an  
additional route.  
Route 4 is used to route traffic to the new LAN connected to the computer with address 192.168.1.5 This route  
is assigned to the LAN interface, which means that instead of traffic being sent onto the ISDN link, it is  
forwarded onto the LAN. The LAN address of the destination is required, because unlike the ISDN link, where  
only one device exists at the other end of the connection, more than one device is connected to the LAN. So,  
the gateway address for this route is 192.168.1.5, which is the computer that provides access to the destination  
LAN. Of course, this computer must be properly configured to forward the datagrams it receives onto the other  
LAN.

IP routes 126  
The Routing Information Protocol (RIP)  
RIP permits the DIVA LAN ISDN Modem to automatically discover routes for itself, by listening to routing  
broadcasts from other networks. If your corporate LAN broadcasts RIP updates, the DIVA LAN ISDN Modem  
will be able to discover routes to all subnets connected to it. For example, if a subnet does not have the same  
network address as your corporate network (as above), you need to create a specific route to support it.  
However, since RIP is enabled by default, all you need to do is specify a single route to the corporate network.  
The DIVA LAN ISDN Modem will listen for RIP broadcasts and define the needed routes.  
RIP also works on the local LAN created by the DIVA LAN ISDN Modem. If this LAN is connected to other  
LANs, RIP will discover the routes to these LANs (if they are configured to broadcast RIP routing  
information).  
Defining routes for the DIVA LAN ISDN Modem  
You always need to have at least one route. When you use the Internet wizard, the default route (0.0.0.0) is  
automatically created for you.  
In some cases, it may be necessary to manually add a route, even though RIP is enabled. To edit the routing  
table, do the following:  
1. Start the Web configuration interface and log in.  
2. Click Manual Configuration.  
3. Click IP.  
4. Click Routes to display the following page. If you previously ran the Internet wizard, the routing table  
should have at least one entry in it, the default route 0.0.0.0.  
Note Only one default route can be defined for the DIVA LAN ISDN Modem, and its network address is  
always 0.0.0.0. Since the Internet wizard automatically creates a default route for the ISP profile, you  
must delete this route if you want to use a default route with the Corporate profile.  
Use the explanations below to guide you in defining more routes.  
• Network address: Specifies the IP address of datagrams that should be routed. The address you set  
here is compared against the destination address in all datagrams that pass through the DIVA LAN  
ISDN Modem. If a match is found, the datagram is routed to the profile specified under Interface.  
• Mask: Lets you specify the number of bits that are checked when the DIVA LAN ISDN Modem  
compares the address of a datagram to that specified by the Network Address parameter. See “About  
IP addresses” on page 120 for more information.

Chapter Nine: Advanced Installations  
IP routes 127  
• Gateway address: Only used if the Interface is set to LAN. This is the address of the device you  
want to send the routed traffic to. This will usually be the address of a bridge or router.  
• Interface: Choose the name of the profile you want to send the routed data to. The profile you  
choose should establish a connection to the proper destination so that routing is successful. If you  
select LAN, data is routed onto the local Ethernet LAN created by the DIVA LAN ISDN Modem.  
• Metric: Metric determines the weight of a route. If two identical routes exist, then the DIVA LAN  
ISDN Modem uses the route with the lower metric.

Output from filter stack  
Each profile has its own filter stack. However, note that once any filter is activated, all incoming and  
outgoing data passes through the filter stack. By default, the DIVA LAN ISDN Modem defines three filters.  
This means, unless you turn these filters off, all incoming and outgoing data passes through the filter stack.  
Note More sophisticated filters can be defined using the command line interface. See Chapter Ten for more  
information.

Chapter Nine: Advanced Installations  
IP filters 129  
Default filters  
By default, the DIVA LAN ISDN Modem defines the following three filters for the ISP profile:  
The first two filters prevent outside access to the web-based configuration interface and the CLI by discarding  
incoming HTTP and Telnet traffic. When you enable remote management, these filters are deleted.  
The last filter is required because, by default, any traffic that is not forwarded is discarded when it reaches the  
bottom of the stack. This filter must be set to operate on all traffic (incoming and outgoing) because, once a  
filter is activated, all traffic passes through the filter stack.  
What is a datagram?  
Data on an IP network is carried in small packages called datagrams. Along with the data it is carrying, each  
datagram contains the IP address of its source and destination.  
To define a filter  
Filters become active immediately after they are defined. You do not have to reset the DIVA LAN ISDN Modem  
to activate them. If you are defining a filter that affects your connection to the DIVA LAN ISDN Modem, you  
will lose contact immediately after saving.

IP filters 132  
• any well known: Applies the filter to any protocol using TCP or UDP ports in the range 0 to 1023.  
See RFC 1700 for the complete list of protocols.  
• UNIX: Applies the filter to any protocol using TCP or UDP ports in the range 512 to 1023. See RFC  
1700 for the complete list of protocols.  
• TCP: Many protocols (such as HTTP, FTP, Telnet, News) make use of TCP. If you filter all TCP  
traffic you will prevent the use of these protocols. Note that access to the web configuration interface  
occurs via HTTP and access to the command line interface (CLI) occurs via Telnet.  
• UDP: Many protocols (such as SNMP, Time, TFTP, BOOTP) make use of UDP. If you filter all UDP  
traffic, you will prevent the use of these protocols.  
• FTP: Applies the filter to all datagrams containing the file transfer protocol.  
• Web (HTTP): If you filter all HTTP traffic, you may not be able to reach the web configuration  
interface. Filtering outgoing HTTP traffic can be used to prevent users from browsing on the Internet.  
• Mail (SMTP): Applies the filter to all datagrams containing the mail (SMTP) protocol.  
• Mail (POP3): Applies the filter to all datagrams containing the mail (POP3) protocol.  
• Telnet: If you filter all Telnet traffic, you will not be able to reach the command line interface (CLI).  
• TFTP: The DIVA LAN ISDN Modem can function as a TFTP server to support uploading and  
downloading of configuration files. If you filter TFTP traffic, you will not be able to use this feature.  
• DNS: Domain name system. Filtering DNS datagrams can cause disruptions in the ability to access  
remote sites.  
The following options are also available: NFS/RPC, News, Time (NTP), BOOTP, SNMP, ICMP, Ping  
(ICMP), Ping Reply, ICMP Redir. For a description of these protocols, consult the appropriate RFC at the  
site www.faqs.org.  
8. Activate the filter by clicking the box that appears to the right of the EDIT button.  
9. Click Save. This makes the filter operational.  
Note Unlike other configurations settings, you do not have to reset the DIVA LAN ISDN Modem to make  
filters operational.  
IP filtering examples  
The examples in this section illustrate how to use filters to:  
• Dropping incoming traffic from a specific network  
• Allowing incoming traffic only from a specific network  
• Blocking web surfing  
Note These examples assume that you have not enabled remote management. If enabled, the default filter  
stack you see will only contain the single filter: “Forward all datagrams being sent from anywhere that contain  
any protocol.“ If no filters are present, the only visible filter will be "Drop All". The "Forward all" filter is  
active but invisible.  
Dropping incoming traffic from a specific network  
This example defines a filter to make sure that no traffic is accepted from a specific network. Assume the  
network has the IP address 213.112.12.0.  
Since the filter is applied against data from the Internet, it is defined for the ISP profile. Place this filter in the  
third position in the stack.

When done, the filter stack should look like this:  
Allowing incoming traffic only from a specific network  
This example shows how to allow the DIVA LAN ISDN Modem to only receive incoming data from a specific  
network (112.111.212.0) on the Internet. Data from all other networks is dropped. However, outgoing traffic is  
not affected.  
This requires defining two filters. Since these filters are applied against data from the Internet, they are defined  
for the ISP profile.  
1st filter  
Define the 1st filter to forward only incoming traffic from 112.111.212.0. Place this filter in the third position  
in the stack.  
2nd filter  
Define the 2nd filter to forward all outgoing traffic. The easiest way to do this is to edit the existing filter that is  
set to “Forward all datagrams being sent from anywhere that contain any protocol.” Change it to “Forward  
outgoing datagrams being sent from anywhere that contain any protocol.”

Making a V.120 connection 136  
Making a V.120 connection  
V.120 was designed to allow non-ISDN devices to communicate with the ISDN network. The DIVA LAN  
ISDN Modem provides support for V.120, so you can connect with such legacy systems. For example, in many  
countries around the world, Compuserve offers access to their network over ISDN, using the V.120 protocol.  
In general, you should use V.120 only when the site you are connecting to requires it. Once the V.120  
connection is active, the DIVA LAN ISDN Modem automatically establishes a PPP connection on top of it.  
This is why you will see this option listed as PPP over V.120 on the configuration screens.  
To make a V.120 connection you must do two things:  
• Configure the V.120 protocol for the profile that will make the connection.  
• Define a V.120 script to automatically log on to your ISP. The DIVA LAN ISDN Modem contains a  
pre-defined script that should work in the majority of cases. However, you may need to modify this script  
for your installation.  
To configure the V.120 protocol  
1. On the Configuration main menu, click V.120. You will see the following page:  
2. Define the V.120 parameters to match the settings of the remote site you are going to connect to. For  
information on each parameter consult the online help by clicking the parameter name.  
3. Click Save.  
4. On the Configuration main menu, click Connection Profiles.  
5. Click Edit for the profile that will make the V.120 connection.  
6. Click Connection on the menu bar.  
7. Select PPP over V.120 as the Protocol.

connection is established, this script is automatically run to complete the log in process. Consult your ISP  
to determine the sequence of events that occur during the log in process. Then modify this script  
accordingly. The following commands are available:  
• Send: Sends the specified text to the remote. Enter up to 33 alphanumeric characters.  
• Send username: Sends the Local username (set on the Authentication page) to the remote.  
• Send password: Sends the Local password (set on the Authentication page) to the remote.  
• Wait for: Pause script execution until the specified text is sent by the remote system. Enter up to 33  
alphanumeric characters.  
• Delay: Pauses script execution for the specified number of seconds. Range: 1 to 255 seconds.  
• Timeout: If the next script event does not complete within the time specified, the script is aborted.  
Range: 1 to 255 seconds.  
• Abort: End the script.

SecurID support 138  
SecurID support  
When establishing a connection to a SecurID server, a special username and password must be supplied to log  
on. The server will request this information during authentication. In order to reply to the request, the DIVA  
LAN ISDN Modem must obtain the log on information from the user that initiated the connection. To support  
the dynamic collection of username and password, the Eicon SecurID Client application must be installed on  
the user’s computer.  
For example:

DIVA LAN ISDN Modem  
The user on computer C attempts to access a resource on Network 1. Before the DIVA LAN ISDN Modem  
places the call, it requests a SecurID username and password from the Eicon SecurID Client on computer C,  
which causes the Eicon SecureID Client to display a dialog box to the user. The user fills in the appropriate  
information and clicks OK. The Eicon SecurID Client forwards the information to the DIVA LAN ISDN  
Modem, which then places the call. When the SecurID server asks for authentication, the DIVA LAN ISDN  
Modem sends the SecurID username and password. If correct, the connection is established.  
Note Once the connection to the SecurID protected server is established, all users on the internal LAN have

Chapter Ten: Other Configuration Tools  
Command line interface (CLI) 148  
About configuration context  
The command line interface identifies the configuration context you are in by changing the prompt. When you  
first activate the CLI interface you are in the General configuration context, which is identified by a plain  
prompt (>). All other contexts are identified by a label added to the prompt.  
About profiles  
To make the configuration of the DIVA LAN ISDN Modem easier, the parameters that control its operation  
have been combined into groups according to function. These groups are called profiles. When you want to  
customize the operation of the DIVA LAN ISDN Modem, you use a CLI command to change the setting of a  
parameter in one of its profiles. To do this, you must set the focus (also called the configuration context) of the  
command line interface to be on the profile.  
Connection profiles  
Certain profiles define the characteristics of a connection, instead of just operational settings for the DIVA  
LAN ISDN Modem. For example, the ISP profile defines a connection that enables the DIVA LAN ISDN  
Modem to connected to an Internet service provider. When the profile is active, the features and functions  
defined by the profile are active. In the case of the ISP profile, it means the DIVA LAN ISDN Modem will dial  
and connect to the ISP whenever a computer attempts to browse the Internet.  
Default profiles  
The DIVA LAN ISDN Modem has following default profiles:  
• ISP: This profile is created by the Internet Wizard. It defines the settings for a connection to the Internet.  
• Corporate: This profile can be used to define the settings for the connection to a remote corporate site.  
• LAN: This is an internal profile that is part of the default configuration of the DIVA LAN ISDN Modem.  
It defines the settings for the LAN created by the Ethernet hub built into the DIVA LAN ISDN  
Modem.You can change the settings of this profile, but you cannot deactivate it.  
• Incoming: This is an internal profile that is part of the default configuration of the DIVA LAN ISDN  
Modem. It defines how the DIVA LAN ISDN Modem handles incoming data calls.You can change the  
settings of this profile. By default, support for incoming calls is disabled.  
Command line reference  
See Appendix C for a complete list of all CLI commands and their descriptions.  
Loading firmware with the CLI  
The DIVA LAN ISDN Modem firmware is the program that resides on the modem and controls all its  
functions. Periodically, Eicon Technology may make new versions of the firmware available that improve the  
performance of the modem or add additional features. To take advantage of these updates you must retrieve the  
appropriate firmware module and load it on the DIVA LAN ISDN Modem.  
Note This section describes how to update the firmware using the CLI interface. The firmware can also be  
easily upgraded using the web-based configuration interface and your web browser. See “Upgrading the DIVA

Appendix B: Technical Information  
Termination 161  
Termination  
If you are in North America or Australia and you are installing a DIVA LAN ISDN Modem with an S/T  
interface, you must connect the terminating resistor to ensure the proper operation of your equipment.  
Determining termination requirements  
Termination requirements vary depending on the number of devices connected to an external NT1 and the  
distance between these devices and the NT1.  
Single ISDN device  
If the DIVA LAN ISDN Modem is the only device connected to the external NT1, then determine the length of  
the cable linking the two devices.  
If the cable is longer than 75 meters (250 feet):  
• Connect the included terminating resistor.  
• Set the NT1 to provide 100 ohms of resistance. Consult the manual provided with the NT1 for more  
detailed instructions.  
Note Some NT1s do not support connections over 75 meters (250 feet). Check your user documentation to  
determine the distance supported.  
If the cable is shorter than 75 meters (250 feet):  
• Do not connect the included terminating resistor.  
• Set the NT1 to provide 50 ohms of resistance. Consult the manual provided with the NT1 for more  
detailed instructions.  
Multiple ISDN devices  
If the NT1 is connected to more that one ISDN device, determine the length of cable connecting the DIVA  
LAN ISDN Modem to the NT1.  
If the cable is longer than 75 meters (250 feet):  
• Connect the included terminating resistor.  
• Set the other ISDN devices to 100 ohms of resistance. Consult the manuals provided with these devices  
for more detailed instructions.  
• Set the NT1 to no termination. Consult the manual provided with the NT1 for more detailed instructions.  
Note Some NT1s do not support connections over 75 meters (250 feet). Check your user documentation to  
determine the distance supported.  
If the cable is shorter than 75 meters (250 feet):  
• Do not connect the included terminating resistor.  
• Set the other ISDN devices to no termination. Consult the manuals provided with these devices for more  
detailed instructions.  
• Set the NT1 to provide 50 ohms of resistance. Consult the manual provided with the NT1 for more  
detailed instructions.  
Installing the resistor  
If termination is required, install the 100 ohm terminating resistor that is included in your package as follows:  
1. Insert the RJ-45 end of the ISDN cable into the resistor

Appendix C: Command Line Reference  
Callback 166  
Callback  
SET CALLBACK MODE type option [number1 number2]  
Valid context: Profile/PPP  
Several callback modes are available. Each provides different features. For callback to work, both client and  
server must use the same mode. The DIVA LAN ISDN Modem can only function as a callback client.  
type: NONE, NCP, ISDN  
NONE: No callback.  
NCP: Supports both the USERSPEC and ADMINSPEC options. This is a Microsoft-developed solution. It is  
used by NT4, and devices from Cisco, Ascend, and other vendors. NCP enables you to specify a time delay  
before the server calls back.  
ISDN: The server does not answer the initial call from the DIVA LAN ISDN Modem (thus there is no charge  
for the call). The remote uses caller ID information to return the call. Only works with Cisco IOS.  
option: USERSPEC, ADMINSPEC  
USERSPEC: (user specified) The DIVA LAN ISDN Modem must supply the server with the callback number  
to use. The number must include the appropriate dialing prefixes.  
ADMINSPEC: (administer specified) The DIVA LAN ISDN Modem does not supply the server with a number  
to dial, instead the server maintains its own table of numbers. The server identifies the DIVA LAN ISDN  
Modem by its caller ID or user ID (supplied during call authentication). The server then uses this information  
to determine which number to dial for callback.  
number1: USERSPEC only. This is the first number that the server dials when calling back. It should be the  
first ISDN number assigned to the DIVA LAN ISDN Modem, and include all required dialing pre-fixes.  
number2: USERSPEC only. This is the second number that the server dials when calling back. For example, if  
you have two ISDN numbers, and you want to establish an MLPPP connection, the server must call in twice,  
once to establish each channel.  
SET CALLBACK TIMEOUT seconds  
Valid context: Profile/PPP  
Sets the amount of time the DIVA LAN ISDN Modem waits for the server to call back. During this time, the  
DIVA LAN ISDN Modem will refuse incoming calls that are not from the callback server on the phone number  
that was configured for callback.  
seconds: Length of delay in seconds. Range: 20 to 240. Default: 30.  
SET CALLBACK DELAY seconds  
Valid context: Profile/PPP  
Callback control protocol only. Sets the amount of time the server waits before calling back. The DIVA LAN  
ISDN Modem proposes the delay during callback negotiation. The server can either accept or reject it.  
seconds: Length of delay in seconds. Range: 1 to 30. Default: 5.  
SHOW CALLBACK CONFIGURATION  
Valid context: Profile/PPP  
Displays the current setting of all callback parameters for the current profile.
