T1/E1 DACS Administrators’ Reference Guide
Introduction
You may configure the digital cross connect (DACS) by using its internal HTTP/HTML Administration
Pages. However, to enter into the HTTP/HTML pages, you must first define the LAN Address Technique,
LAN IP Address, and LAN Subnet Mask for the DACS. If you have not done so, please refer to the Getting
Started Guide that came with your DACS.
Logging into the HTTP/HTML Administration Pages
To log into the HTTP/HTML Administration pages, you must enter the 4-octet Internet Protocol (IP) (for
example, http://your.server.ip.address) address as the Universal Resource Locator (URL) into a World-Wide Web
(WWW) browser. After you enter the IP address, the DACS will ask for your user name and password as
Figure 1. DACS login window
Your DACS will accept the following default administrative passwords:
• superuser—this password carries full permission to change and view any parameters in the DACS
• monitor—this password allows full viewing of any non-password oriented variables.
Note For security reasons, we recommend that you change these passwords
immediately after initial configuration.
HTTP/HTML and SNMP Object Format
In this document, we shall describe the variables found on each of the internal HTTP/HTML pages. This
description will include brief definitions of the Patton Enterprise MIB or SNMP MIB II object identifiers
wherever applicable. The format of the variables will resemble figure 2.

Saving HTTP/HTML Object Changes
Sometimes you will need to save changes that you have made in the HTTP/HTML pages. Do the following to
make changes to read/write variables:
1. Select the appropriate Modify screen.
2. Make changes to the desired parameter.
3. Click on the Submit Query button.
4. Return to the HOME screen.
5. Click on the Record Current Configuration button.
Note Make sure you follow steps 1 through 5 when modifying the HTTP/
HTML pages. Otherwise, your changes will be lost when the DACS
is power-cycled.

Introduction
This chapter describes the HOME window—the first Administration Page that you see after logging into the
changes, or reset the system without power-cycling the DACS.
Note Clicking on the HOME link in the Configuration Menu pane will
return you to the HOME page from any other page.
The HOME window is divided into two panes: the Configuration Menu pane on the left-hand side and the con-
figuration/information pane (see figure 3). The Configuration Menu contains the links to the various DACS
subsystems, while the configuration/information pane is where you can view status and other information, or
make changes to the system configuration. Unlike the Configuration Menu pane, which looks the same no
matter which subsystem page you are viewing, the configuration/information pane contents will change as you
move from one subsystem page to another.

Operating Status Variables
There are seven system variables which describe the immediate operating status of the DACS. These variables
Figure 4. STATUS menu
% CPU Idle (boxIdleTime)
This is an indication of the amount of system CPU power which is not being utilized by the Model 2604. The
return value is a percentage of free CPU cycles since the last time the variable was read.
Running Since Last Boot (sysUpTime)
The time (in hundredths of a second) since the DACS was last power-cycled.
Total System Alarms (alarmTotal)
Total number of alarms currently active in the system.
Immediate Actions
There are several immediate actions (see figure 5) in superuser mode which will cause the DACS to operate
according to the descriptions in the following sections.
Figure 5. Immediate Actions buttons
Record Current Configuration (storeConfig(1))
This feature saves the current configuration in permanent FLASH memory. In other words, configuration
changes made in the subsystem web pages become permanent when you select Record Current Configuration.
1. Configuration changes in the DACS are made in the subsystem web pages by clicking Submit Query.
This stores the configuration in volatile DRAM (Dynamic RAM) only. Since the Submit Query changes
take immediate effect, the administrator can test different configuration parameters without needing to
change the FLASH configuration at this moment.

2. Without clicking on Record Current Configuration, all configuration changes will be lost if the power
is recycled. After doing the Record Current Configuration save, the current configuration of the DACS
will not be lost with power cycling.
Note The most important step after completing the configuration is to save it in
permanent memory by clicking on Record Current Configuration.
Hard Reset (hardReset(2))
This button causes the DACS to perform a cold restart. When you select Hard Reset, the DACS requests con-
firmation for the execution of this command. Then, the DACS will disconnect all current sessions, re-initialize
the interfaces, and re-load configuration parameters from FLASH.
Set Factory Default Configuration (forceDefaultConfig(3))
This button clears out the configuration in FLASH and loads the factory default parameters into FLASH
memory. The factory default settings will not execute on the DACS until it is re-booted, for example by doing
a Hard Reset.
Note Set Factory Default Configuration will delete the DACS’s Ether-
net IP address and any other site specific settings made for your par-
ticular installation. You will have to re-enter the DACS’s Ethernet IP
address and netmask using the front panel control port in order to use
the HTTP/HTML Management pages.

T1/E1 DACS Administrators’ Reference Guide
Introduction
The Import/Export function enables you to make a backup (or export) copy of your DACS’s configuration
parameters. By exporting the configurations, the saved files can quickly be loaded, or imported, into a replace-
ment DACS—greatly speeding up the installation process should a DACS need replacing.
Note All actions for Import/Export require superuser access privileges.
To import or export a configuration, click on Import/Export under the Configuration Menu to display the
Figure 6. Import/Export main window
Export Configuration
Note The exported configuration file is a text-format file. Do not try, how-
ever to edit the operating characteristics contained in the file.
Note The parameters that will be exported are the power-up settings as
they are stored in flash memory and may not be the current operating
parameters. To ensure that you export the most current parameters,
go to HOME, then click on the Record Current Configuration button
under Immediate Actions.

Import Configuration
To import a configuration file into the DACS, type the complete path and filename for the configuration file
you wish to load or click on the Browse… button to select the desired file, then click on the Submit Query but-
Upon successfully importing the file, the DACS will display Configuration Load Complete, indicating that the
new operating parameters have been loaded into flash memory.
Click on HOME under the Configuration Menu, then click on the Hard Reset button under Immediate Actions.
Note Do not select Record Current Configuration after importing configu-
ration parameters because the configuration is imported directly into
non-volatile FLASH memory. Upon doing a Hard Reset the
imported configuration is now the operational software is RAM.

T1/E1 DACS Administrators’ Reference Guide
Introduction
The DACS has an extensive alarm reporting system which enables users to configure, monitor, and test major
and minor alarms. The alarm system can be set to notify of equipment failures (for example, a power supply
failure) or T1/E1 port malfunctions. There are 83 alarms that can be configured by the system administrator to
generate alerts based on the condition of the DACS.
Displaying the alarms window
Note The system administrator can manually generate a specific alarm for
testing purposes or clear the alarm counters from the main window.

4 • Alarms
The T1/E1 DACS Multiplexer has four methods to notify an alarm condition:
1. Front panel LED—The front panel ALARM LED has three states that indicate the presence and severity
of an alarm. The states are:
- Off—No alarm present
- Solid—Minor alarm
- Flashing—Major alarm.
Note The POWER LED will flash if a power supply failure alarm is
present.
2. Administration web page indication—The Alarms window of the administration page uses red highlight-
ing to indicate which items are in an alarm state (see figure 10).
Figure 10. Sample alarm indication
3. SYSLOG/SNMP—For external notification, the DACS can be configured to send a SYSLOG message or
an SNMP TRAP to an external management host. To configure the alarm response for either SNMP Traps
4. Alarm Relay—Located on the rear of the chassis, the Alarm Relay is a 3-position terminal block. The
Alarm Relay may be configured to indicate when a major alarm, a minor alarm or both major and minor
alarms occur. It may also be disabled. The 3-position terminal block numbers its pins from 1 to 3 from left
to right. When no alarms are indicated, pins 1 and 2 are normally closed and pins 2 and 3 are normally
open. Upon the occurrence of an alarm—the type is configured as major, minor, or both—pins 1 and 2 are
open and pins 2 and 3 are closed.
Besides enabling a user to view current alarm status, you may manually generate an alarm as a test and clear the
alarm time and count variables. The Alarms main window also contains links to the following:

Relay Response
The relay of the Alarm Port on the rear of the chassis will be activated when a major, minor, or both major and
minor alarm is generated. The Alarm Port may also be disabled.
Minor Alarm SYSLOG Priority (minSyslogPriority)
Sets the priority of the minor alarm SYSLOG message that will be generated upon the occurrence of a minor
alarm.
Major Alarm SYSLOG Priority (majorSyslogPriority)
Sets the priority of the major alarm SYSLOG message that will be generated upon the occurrence of a major
alarm.
Minor Alarm SNMP Trap IP [address] (minorTrapIp)
Displays the IP address of a SNMP management station for receiving the SNMP trap messages upon the
occurrence of an active minor alarm. The SNMP trap messages are sent in UDP datagrams. When the IP
address is set to 0.0.0.0, no trap messages will ever be sent.
Major Alarm SNMP Trap IP [address] (majorTrapIp)
The same function as the Minor Alarm Trap IP except for only the occurrence of active major alarms.
Temperature Threshold
An alarm will be generated when the box temperature exceeds this temperature value in degrees Celsius.
Current Box Temperature
The internal temperature in the box in degrees Celsius.
Clear All Alarms
Click on this button to clear all the alarms (that is, to reset all the alarms). This clearing action will, for all the
alarms, reset the alarm, reset Time Since Alarm to 0.00 seconds, and reset the Alarm Count to 0 (zero).

The Alarm Status Table on the Alarm System main page displays the current alarm status. You may also man-
ually generate an alarm as a test and clear the alarm, the alarm time and the alarm count variables.
• Alarm ID—The Alarm ID identifies the alarm numerically. E.g., Alarm ID #2 identifies the alarm named
“Box: Power Supply I Failed.”
• Alarm Name—The alarm items are grouped into two categories: Box and WAN alarms. The Box alarm
group contains the alarms “Over Temperature” and “Power Supply Fail” for each of the two power supplies.
The WAN alarm group includes yellow and red alarms.
• Alarm Severity—For each alarm, it shows whether the alarm is disabled or configured to generate a major,
minor, major self-clearing, or minor self-clearing alarm.
• Time Since Alarm—Elapsed time since the alarm occurred.
• Alarm Count—The number of times this alarm has occurred since it has been cleared. It is also for moni-
toring self-clearing alarms.
• Generate Alarm—For testing a particular alarm, click on Generate Alarm. This activates the alarm as if the
actual trigger event had occurred.

Types of Alarms
• Box Alarm Group
- Box: Over Temperature—When the internal box temperature exceeds the temperature threshold under
Modify Response…, an alarm will be generated.
- Box: Power Supply I – II Fail—An alarm will be generated when a power supply fails.
• WAN Alarm Group
- WAN 1 – 4: Yellow Alarm—When a WAN port sees a yellow alarm, the specific WAN alarm will be sent.
- WAN 1 – 4: Red Alarm—When a WAN port sends a red alarm, the specific WAN alarm will be sent.
Modify Response—Configuring the alarm response system
The alarm response outputs refer to points of external notification. Note that the front panel Alarm LED and
the web administration pages will always indicate an occurrence of an active alarm. To configure each alarm
response output, click on Modify Response. The Alarm Response System page appears (see figure 11). Choose
the alarm response output that you want to configure with the pull down menu. After configuring a specific
alarm response output, remember to click on Submit Query before going to the next alarm response output;
otherwise the change will not occur.
Relay Response
The relay may be set to go active for minor alarms, major alarms, or both. It may also be disabled with the
parameter “none.”
Minor Alarm Syslog Priority & Major Alarm Syslog Priority
When a minor/major alarm occurs, a message of the selected priority is sent to the Syslog engine. The Priority
levels are priorityDisable(100), prioritySystem(80), priorityService(60), priorityOddity(40), priorityInfo(20),
priorityDebug(10), and priorityVerbose(5). For more information on Syslog messages, refer to Chapter 16,
Minor Alarm SNMP Trap IP [address] (minSyslogPriority)
Upon the occurrence of a minor alarm, an SNMP Trap message is sent to a host system (or a management sta-
tion). This parameter is the IP address of the host running the SNMP Trap daemon. When the IP address is set
to 0.0.0.0 no SNMP Trap message will be sent.
Major Alarm SNMP Trap IP [address] (majorSyslogPriority)
This parameter functions in the same manner as the Minor Alarm SNMP Trap IP [address] except it applies to
major alarms. Upon the occurrence of a major alarm, an SNMP Trap message is sent to a host system (or a
management station). This parameter is the IP address of the host running the SNMP Trap daemon. When the
IP address is set to 0.0.0.0 no SNMP Trap message will be sent.

Temperature Threshold
An alarm message is generated when the internal box temperature exceeds this threshold value (degrees Cel-
sius). You can change the threshold temperature, but we recommend that you use the factory default.
Modify Alarms—Configuring alarm severity levels
Clicking on Modify Alarms window (see figure 12) displays a table listing each individual alarm. From this
page you can configure the severity for each alarm (such as major, minor, major self-clearing, and minor self-
clearing). Each alarm can be disabled as appropriate for your application.
Figure 12. Modify Alarms settings window
There are 83 alarms that can be independently configured to generate alarm messages. Each alarm item can be
set for one of the following severity levels:
• Ignore(0)—Do not generate an alarm.
• Minor(1)—Generate a minor alarm that will not reset until the administrator manually clears it.
• Major(2)—Generate a major alarm that will not reset until the administrator manually clears it.

• MinorSelfClearing(3)—Generate a minor alarm that automatically clears after a fixed period of time. If the
alarm condition has not ceased, the alarm will be automatically cleared, but another alarm will be immedi-
ately generated. If the alarm condition has ceased, the alarm will be automatically cleared after the same
fixed period of time.
• MajorSelfClearing(4)—Same as MinorSelfClearing(3) except that it is a Major alarm instead of Minor.
Note For maximum application flexibility, the administrator shall choose
which constitute major or minor alarm. Some examples of typical
major and minor alarms include:
- Box: Over Temperature—Major Alarm
- WAN 1: Red Alarm—MajorSelfClearing
- WAN 1: Yellow Alarm—MinorSelfClearing

Help (DACS help information)
Clicking on the Help button displays the DACS Help Information window (see figure 14). The purpose of
this window is to help the user learn how to add DS0 connections using the DACS HTML pages. This win-
dow define all of the parameters available within this web page. If you are using the Command Line Format to
make connections, scroll down the window to the heading Command Line Format. The information contained
in the Help window is also covered in this chapter.
Figure 14. Example DACS Help Information window
Static Connection
Pull Down Menus
Each pull down window signifies part of a connection. Each connection is made up of an "A" side and a "B"
side. These names have been arbitrarily chosen and do not signify the direction that data will travel. All data
will be bi-directional. There are three parameters that need to be defined for each connection, they are:
• Device Type
• Device Number
• Device Slots
ID
Then ID number identifies each mapping with a unique number. The number is automatically assigned
sequentially when a static connection is entered. The ID number begins at “1.”
Device Type
The Device Type specifies the physical interface that you will be connecting. Within the 2604 the user has the
option of selecting either a T1/E1 WAN line or a DACS. While the one side may be a T1/E1 WAN line and
the other a DACS, note that both sides of the connection can be T1/E1 or both sides can be iDSL. The two
Device Types are t1-e1(1) and t1-e1(2).
Device Number
The next step in creating a connection through the DACs is to select the port that you would like to use. This
corresponds to the Port Number for the devices selected in the previous step. For example, if you would like to
make a connection to port 3 (referring to DACS #3), then select "Port 3" in the "Device Number" field. Note
that there are only four t1-e1 ports so you may not select t1-e1 ports 5 - 24. This will generate an error in the
system. Since there are 24 DACSs within the 2604, you may choose any of the 24 ports.

T1/E1 DACS Administrators’ Reference Guide
Device Slots
The "slots" input identifies the DS0 channels—each DS0 channel is 64 kbps—that you would like to con-
nect. Each time slot in a T1 or E1 WAN port has 24 or 31 DS0 channels, respectively. When selecting the
slots you must select the same number of slots on the "A" and "B" side of the connection. The slots are selected
by entering a string that represents the slots. For a WAN port configured as a T1, the available slots are num-
bered from 1 - 24. For a WAN port configured as an E1, the available slots are 1 - 31. The following notation
should be used for entering the slots. Several examples are given below.
• dash: (-) 1 - 4
• comma: (,) 1,4,9
• combo: 1 - 2, 3,6 - 7
For example, to connect a T1 Port using timeslots 1,2, 5, 6, 7, and 15, you can input any of the following
strings:
1,2, 5-7, 15
1 - 2, 5,6,7,15
1 - 2, 5 - 6, 7, 15
Configuration
The user can make connections in the box using two different methods. The easiest way is by using the pull
down windows provided. But the user can also add connection using the command line format by entering a
text string. To input a static connection into the box using the text string. Use the following convention:
• DeviceA:PortA:SlotsA/DeviceB:PortB:SlotsB
Device Options - The interface that you would like to select
t1-e1
Port Options - The Port Number (starting at 1) may be one of the four WAN ports. To configure Slots
(DS0 channels), choose the slots that you would like to use. The following notations are allowed:
1) dash (-): 1 - 4
2) comma (,): 1,4,9
3) combination of dashes and commas: 1 - 2, 3,6 - 7
Example: To connect a T1 line, Port 1, timeslots 1 and 2 to a T1 line, Port 2, timeslots 5 and 6, input the
following string:
t1-e1:1:1-2/t1-e1:2:5-6

Introduction
Click on Clocking in the Configuration Menu to display the System Clocking Configuration main window
Figure 15. System Clocking Configuration window
The Clocking window is where the primary and secondary clocking sources that synchronize all DS0 channels
are configured. The DACS uses a single clock source for all DS0 channels. You select the clock for the DS0
channels from the following clock sources:
• An internal oscillator
• Any of the WAN ports
• An external clock (accessed via the Ext. Clock 3-position terminal block located on the rear panel of the
DACS.”
The Main Reference setting determines the clock source if this source is operational. If the Main Reference
clock source fails, the Fallback Reference becomes the clock source to synchronize all DS0 channels. The
clock source is the system clock for the entire DACS.
Configuring the System Clock Settings
The following sections describe configuring the clock settings.
Main Reference (daxClockMainRef)
The Main Reference and Fallback Reference parameters have the same selections for system clock. Make sure
you choose different clock sources for the Main Reference and Fallback Reference. The following settings

8 • Filter IP
T1/E1 DACS Administrators’ Reference Guide
Introduction
The DACS software provides an IP filtering system that enables you to set up security for the internal manage-
ment system.
Each filter is a defined list of parameters based upon attributes in the IP, TCP, and UDP headers. There are two
major steps to filter creation: first defining the filter, then applying it to a user connection. The same filter can
be shared by several users.
The DACS enables 20 separate filters to be defined, of which up to 10 can be used during a single user connec-
tion. Since the IP connections in the 2604 are only for the superuser and the monitor user, these will be the
only two users. The application of the filters is done on the Filter IP main web page.
Figure 17. Filter IP main window
Defining a filter
This section gives a brief summary on defining a filter. For a complete discussion with filter examples, see the
final section.
To define a new filter, select an ID number and a name, then click on the Submit Query button to submit the
request. The ID number and name must not already exist in the IP FILTER list, and the number must be an
integer between 1 and 20. To delete a filter, enter just the ID number without a name and click on the Submit
Query button.
Note Block filters take priority, therefore any applied and matching block
filters will drop the packet. Next, pass filters are examined, if PASS fil-
ters have been defined, then at least one of them must match or else
the packet will be dropped. After the block and pass filters are exam-
ined, the WRAP filter, if it exists, will be applied.

• inbound(1)—Relates to packets coming into the DACS
• outbound(2)—Relates to packets leaving the DACS
• both(3)—Specifies both inbound and outbound operation
Action (filterIpAction)
Specifies the action to effect the packet. The action decides whether to block or pass the packet. The following
options are available:
• pass(0)—If pass is selected, checking will continue on to other filters until either a match occurs, a block
occurs, or there are no more filters remaining to check.
Note If there are any applied PASS filters, then at least one of them must
match or the packet will be dropped.
• block(1)—If a filter has block set and the filter matches the block, the packet is discarded and no further
processing is done.
• wrap(2)—All packets received on the specified link will be encapsulated in an extra IP header as defined in
RFC2003. The destination IP address of the wrapper is given by the destination IP setting in the filter. The
source IP address of the wrapper is the ethernet address of the DACS.
All wrap filters are inbound only.
Source IP (filterIpSourceIp)
This is the Source IP address in the IP header, it is used when comparing a packet’s source address.
Source IP Mask (filterIpSourceMask)
This is the Source IP Mask (filterIpSourceMask) used when comparing a packet’s source address. Bit positions
that are set to 1 will be compared and 0’s will be ignored. Thus, a setting of 0.0.0.0 will have the effect of dis-
abling source IP address comparison.
Destination IP (filterIpDestinationIp)
This is the destination IP address in the IP header used when comparing a packet’s destination address.

Destination Mask (filterIpDestinationMask)
This is the destination mask used when comparing a packet’s destination address. Bit positions that are set to 1
will be compared and 0’s will be ignored. Thus, a setting of 0.0.0.0 will have the effect of disabling destination
IP address comparison.

whether the source port in the IP packet is not compared, equal, less than, or greater than the Source Port des-
ignated in the filter.
Action (filterIpSourcePortCmp)
Specifies the Action (filterIpSourcePortCmp) that the DACS compares. The source port action determines
whether the source port in the IP packet is not compared, equal, less than, or greater than the Source Port des-
ignated in the filter.
• noCompare(0) – No Comparison to the source port in the IP packet.
• equal(1)—The port in the source IP packet is the same
• lessThan(2)—The port in the source IP packet is less than
• greaterThan(3)—The port in the source IP packet is greater than
Destination Port (filterIpDestinationPort)
Specifies the destination port number which the DACS compares. The destination action functions similarly
to the Source Port and its Action defined above.
Action (filterIpDestinationPortCmp)
Specifies the action (TCP or UDP) which the DACS compares. The destination action will determine how the
destination port is treated.
• noCompare(0)—No Comparison to the destination port in the IP packet.
• equal(1)—The port in the destination IP packet Is the same
• lessThan(2)—The port in the destination IP packet is less than
• greaterThan(3)—The port in the destination IP packet is greater than
Protocol (filterIpProtocol)
Specifies the IP Protocol number to use for filtering. Some examples of protocol numbers are 1 for ICMP; 6
for TCP; and 17 for UDP. A list of protocol numbers can be found in RFC 1340. A setting of 0 disables pro-
cessing based on protocol number.
TCP Established (filterIpTcpEstablished)
Specifies whether the filter should match only those packets which indicate in the TCP header flags that the
connection is established. The following choices are available:
• anyPackets(0)—Applies the filter to all packets
• onlyEstablishedConnections(1)—Only applies the filter to established TCP connections

T1/E1 DACS Administrators’ Reference Guide
Introduction
When networking problems or undesirable conditions occur, the ICMP protocol is used for communicating
control or error information plus testing. The statistics listed on the DACS ICMP window (see figure 19) com-
prise those contained in RFC 792—Internet Control Message Protocol (ICMP). Implementation of the ICMP
group is mandatory for all TCP/IP networks. RFC 1312—ICMP Group of MIB-II Variables—provides the
definitions of these variables. It is important to remember that any RFC can be superseded by a newer.
Figure 19. ICMP window
Click on ICMP under the Configuration Menu to monitor DACS ICMP statistics.
Block ICMP redirects (boxBLockIcmpRedirects)
The two options for “Block ICMP Redirects” either allow the reception of ICMP Redirect messages [allowre-
directs(0)] or block the reception of ICMP Redirect messages [stopredirects(1)]. The recommended configura-
tion is to block the ICMP redirect messages because in some instances they could alter the routing table with
undesirable effects, which is considered a breach of security.
ICMP Receive/Send Messages window
The ICMP window displays the ICMP message counters. ICMP messages are displayed in the window as col-
umns comprising two types of messages:
• Messages received by the DACS (InMibVariable)
• Messages sent by the DACS (OutMibVariable)
The numbers following the parameters can be a good source of what is happening on the network to point out
potential problems. Both gateways (routers) and hosts can send ICMP messages.
Total Received (icmpInMsgs)
The total number of ICMP messages which the 2604 DACS has received. Note that this counter includes all
those counted by icmpInErrors (see “w/Errors (icmpInErrors, icmpOutErrors)” on page 57).

T1/E1 DACS Administrators’ Reference Guide
9 • ICMP
Total Sent [imcpOutMsgs]
Similar to icmpInMsgs, Total Sent represents the total number of ICMP messages which the 2604 has
attempted to send. This variable includes all ICMP messages counted by icmpOutErrors (see “wo/Errors [icm-
w/Errors (icmpInErrors, icmpOutErrors)
The number of ICMP messages which the Model 2604 received/sent but having ICMP-specific errors (for
example, bad ICMP checksums, bad length, or non-routable errors).
wo/Errors [icmpOutErrors]
The number of ICMP messages which the Model 2604 did not send due to problems discovered within ICMP
such as a lack of buffers. It does not include errors discovered outside the ICMP layer like the inability of IP to
route the resultant datagram.
Destinations Unreachable (IcmpInDestUnreachs, IcmpOutDestUnreachs)
The number of ICMP destination unreachable messages received/sent. For instance, if the information in a
gateway’s routing table determines that the network specified in a packet is unreachable, the gateway will send
back an ICMP message stating that the network is unreachable. The following conditions will send back an
unreachable message:
• The network is unreachable
• The host is unreachable
• The protocol is not available to the network
• The port on the host is unavailable. a specified source route failed
• A packet must be fragmented (that is, broken up into two or more packets) but the packet was sent anyway
with instructions not to be fragmented.
Times Exceeded (icmpInTimeExcds, icmpOutTimeExcds)
The number of ICMP time exceeded messages received/sent. Each time a packet passes through a gateway, that
gateway reduces the time-to-live (TTL) field by one. The default starting number is defined under the IP sec-
tion. If the gateway processing a packet finds that the TTL field is zero it will discard the packet and send the
ICMP time exceeded message. Time exceeded will also be incremented when a host which is reassembling a
fragmented packet cannot complete the reassembly due to missing packets within its time limit. In this case,
ICMP will discard the packet and send the time exceeded message.
Parameter Problems (icmpInParmProbs, icmpOutParmProbs)
The number of ICMP parameter problem messages received/sent. If while processing a packet, a gateway or
host finds a problem with one or more of the IP header parameters which prohibits further processing, the gat-
way or host will discard the packet and return an ICMP parameter problem message. One potential source of
this problem may be with incorrect or invalid arguments in an option. ICMP sends the parameter problems
message if the gateway or host has discarded the whole packet.
Source Quenchs (icmpInSrcQuenchs, icmpOutSrcQuenchs)
The number of ICMP source quench messages received/sent. A gateway will discard packets if it cannot allo-
cate the resources, such as buffer space, to process the packet. If a gateway discards the packet, it will send an
ICMP Receive/Send Messages window

9 • ICMP
T1/E1 DACS Administrators’ Reference Guide
ICMP source quench message back to the sending device. A host may send this messages if packets arrive too
fast to be processed or if there is network congestion. The source quench message is a request to reduce the rate
at which the source is sending traffic. If the DACS receives a source quench, it will wait for acknowledgement
of all outstanding packets before sending more packets to the remote destination. Then it will begin sending
out packets at an increasing rate until the connection is restored to standard operating conditions.
Redirects (icmpInRedirects, icmpOutRedirects)
The number of ICMP redirect messages received/sent. A gateway sends a redirect message to a host if the net-
work gateways find a shorter route to the destination through another gateway.
Echos (icmpInEchos, icmpOutEchos)
The number of ICMP echo request messages received/send. The ICMP echo is used whenever one uses the
diagnostic tool ping. Ping is used to test connectivity with a remote host by sending regular ICMP echo
request packets and then waiting for a reply. Received echos (icmpInEchos) will increment when the DACS is
pinged.
Echo Replys (icmpInReps, icmpOutReps)
The number of ICMP echo reply messages received/sent. An echo reply is a response to an echo request. Send
echos (icmpOutEchos) will increment when the DACS sends an echo reply message in response to a ping.
Time Stamps (icmpInTimestamps, icmpInTimestamps)
The number of ICMP time stamp messages received/sent. Time stamp and time stamp replies were originally
designed into the ICMP facility to allow network clock synchronization. Subsequently, a new protocol—Net-
work time protocol (NTP) has taken over this function. Normally, this number will be zero.
Time Stamp Replys (icmpInTimestampsReps) (icmpOutTimestampsReps)
The number of ICMP timestamp reply messages received/sent. This message is part of a time stamp (see “Time
Stamps (icmpInTimestamps, icmpInTimestamps)”) request. Normally, this number will be zero.
Address Mask Requests (icmpInAddrMasks) (icmpOutAddrMasks)
The number of ICMP address mask request messages received/sent. this message is generally used for diskless
workstations which use this request at boot time to obtain their subnet mask. This number will increase if there
are hosts on the network which broadcast these requests.
Address Mask Replys (icmpInAddrMasksReps) (icmpOutAddrMasksReps)
The number of ICMP address mask reply messages received/sent. Normally, this number will be zero.

Forwarding (ipForwarding)
The indication of whether this entity is acting as an IP gateway in respect to the forwarding of datagrams
received by, but not addressed to, this entity. IP gateways forward datagrams, IP hosts do not (except those
source-routed via the host).
Note For some managed nodes, this object may take on only a subset of the
values possible. Accordingly, it is appropriate for an agent to return a
“badValue” response if a management station attempts to change this
object to an inappropriate value.
The following conditions can be displayed:
• forwarding(1)—acting as a gateway and will forward IP datagrams to other gateways
• not-forwarding(2)—not acting as a gateway so it will discard IP datagrams destined for other gateways
Default Time-To-Live (ipDefaultTTL)
The default value inserted into the time-to-live field of the IP header of datagrams originated at this entity,
whenever a TTL value is not supplied by the transport layer protocol.
Total Datagrams Received (ipInReceives)
The total number of input datagrams received from interfaces, including those received in error.
Discarded for Header Errors (ipInHdrErrors)
The number of input datagrams discarded due to errors in their IP headers, including bad checksums, version
number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options,
and so on.
Discarded for Address Errors (ipInAddrErrors)
The number of input datagrams discarded because the IP address in their IP header’s destination field was not
a valid address to be received at this entity. This count includes invalid addresses (e.g., 0.0.0.0) and addresses of
unsupported Classes (e.g., Class E). For entities which are not IP Gateways and therefore do not forward data-
grams, this counter includes datagrams discarded because the destination address was not a local address.
Forwarded Datagrams (ipForwDatagrams)
The number of input datagrams for which this entity was not their final IP destination, as a result of which an
attempt was made to find a route to forward them to that final destination. In entities which do not act as IP
Gateways, this counter will include only those packets which were source-routed via this entity, and the source-
route option processing was successful.
Discarded for Unknown Protos (ipInUnknownProtos)
The number of locally-addressed datagrams received successfully but discarded because of an unknown or
unsupported protocol.
Discarded w/No Errors (ipInDiscards)
The number of input IP datagrams for which no problems were encountered to prevent their continued pro-
cessing, but which were discarded (for example, due to lack of buffer space).

Note The Discarded w/No Errors counter does not include any datagrams
discarded while awaiting re-assembly.
Total Deliveries (ipInDelivers)
The total number of input datagrams successfully delivered to IP user-protocols (including ICMP).
Out Requests (ipOutRequests)
The total number of IP datagrams which local IP user-protocols (including ICMP) supplied to IP in requests
for transmission.
Note The Out Requests counter does not include any datagrams counted
in ipForwDatagrams.
Out Discards (ipOutDiscards)
The number of output IP datagrams for which no problem was encountered to prevent their transmission to
their destination, but which were discarded (e.g., for lack of buffer space).
Note The Out Discards counter would include datagrams counted in
ipForwDatagrams if any such packets met this (discretionary) discard
criterion.
Discarded for No Routes (ipOutNoRoutes)
The number of IP datagrams discarded because no route could be found to transmit them to their destination.
Note The Discarded for No Routes counter includes any packets counted
in ipForwDatagrams which meet this “no-route” criterion. This
includes any datagrams which a host cannot route because all of its
default gateways are down.
Reassembly Timeout (ipReasmTimeout)
The maximum number of seconds which received fragments are held while they are awaiting reassembly at this
entity.
# of Reassembled Fragments (ipReasmReqds)
The number of IP fragments received which needed to be reassembled at this entity.
# Successfully Reassembled (ipReasmOKs)
The number of IP datagrams successfully reassembled.
Reassembly Failures (ipReasmFails)
The number of failures detected by the IP reassembly algorithm (for whatever reason: timed out, errors, etc).
Note The Reassembly Failures value is not necessarily a count of discarded
IP fragments since some algorithms (notably the algorithm in
RFC 815) can lose track of the number of fragments by combining
them as they are received.

Routing Information
The IP Routing Information window (see figure 24) displays information required to route IP datagrams,
including the IP address, subnet mask, next-hop router, and interface for each network interface defined in the
DACS.
The IP Routing Information window also has a link to the O/S forwarding table where the forwarding param-
eters are displayed (“O/S forwarding table window” on page 68).
Figure 24. IP Routing Information window
Destination (ipRouteDest)
The destination IP address of this route. An entry with a value of 0.0.0.0 is considered a default route. Multiple
routes to a single destination can appear in the table, but access to such multiple entries is dependent on the
table-access mechanisms defined by the network management protocol in use.

Mask (ipRouteMask)
Indicates the mask to be logical-ANDed with the destination address before being compared to the value in the
ipRouteDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value
of the ipRouteMask by determining whether the value of the corresponding ipRouteDest field belongs to a
Class A, B, or C network, and then using the appropriate mask from table 3.

Gateway (RouteGateway)
Specifies the IP address to which the packets should be forwarded.
Cost (RouteCost)
This is the cost of the route as defined by RIP standards. Cost is sometimes considered to be number of hops.
A cost of 16 is considered to be infinite. A cost can be given to user-entered routes so their preference in rela-
tion to learned routes can be calculated.
Interface (ipRouteIfIndex)
The index value that identifies the local interface through which the next hop of this route should be reached.
The interface identified by a particular value of this index is the same interface as identified by the same value
of ifIndex.
State (RouteState)
• invalid(1)—This setting deletes the route.
• active(2)—A valid route is in use.
• nopath(3)—No route is available to the specified gateway. The gateway is not known to local networks.
• agedout(4)—Invalid route (soon to be removed).
• costly(5)—A valid route, but not in use because of it’s higher cost.

O/S forwarding table window
The O/S forwarding table window lists forwarding information for all routes.
Figure 25. IP Routing Forwarding Table
Destination (ipRouteDest)
The destination IP address of this route. An entry with a value of 0.0.0.0 is considered a default route. Multiple
routes to a single destination can appear in the table, but access to such multiple entries is dependent on the
table-access mechanisms defined by the network management protocol in use.
Mask (ipRouteMask)
Indicates the mask to be logical-ANDed with the destination address before being compared to the value in the
ipRouteDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value
of the ipRouteMask by determining whether the value of the correspondent ipRouteDest field belongs to a
Class A, B, or C network, and then using the appropriate mask from table 3 on page 67.
Next Hop (ipRouteNextHop)
The IP address of the next hop of this route. (In the case of a route bound to an interface which is realized via
a broadcast media, the value of this field is the agent's IP address on that interface.)
Interface (ipRouteIfIndex)
The index value that identifies the local interface through which the next hop of this route should be reached.
The interface identified by a particular value of this index is the same interface as identified by the same value
of ifIndex.

• direct(3)—route to directly connected (sub-)network
• indirect(4)—route to a non-local host/network/sub-network
Note The values direct(3) and indirect(4) refer to the notion of direct and
indirect routing in the IP architecture. Setting this object to the value
invalid(2) has the effect of invalidating the corresponding entry in the
ipRouteTable object. That is, it effectively disassociates the destina-
tion identified with said entry from the route identified with said
entry. It is an implementation-specific matter as to whether the agent
removes an invalidated entry from the table. Accordingly, manage-
ment stations must be prepared to receive tabular information from
agents that corresponds to entries not currently in use. Proper inter-
pretation of such entries requires examination of the relevant
ipRouteType object.
Protocol (ipRouteProto)
The routing mechanism via which this route was learned. Inclusion of values for gateway routing protocols is
not intended to imply that hosts must support those protocols.
• unknown(0)
• local(1)—Added by the DACS to support an interface. For example, adding a route for a new dial-in user.
• user(2)—Added by an administrator on the IP Routing Information table or via SNMP management tools.
• dspf(3)—Not currently implemented.
• rip(4)—Learned via reception of RIP packet.
• icmp(5)—Learned via reception of ICMP packet.
• radius(6)—Provided in RADIUS response packet.
Info (ipRouteInfo)
A reference to MIB definitions specific to the particular routing protocol which is responsible for this route, as
determined by the value specified in the route’s ipRouteProto value. If this information is not present, its value
should be set to the OBJECT IDENTIFIER { 0 0 }, which is a syntactically valid object identifier, and any
conformant implementation of ASN.1 and BER must be able to generate and recognize this value.

IP Routing Destination window
Figure 26. Routing Destination window
Route Destination (ipRouteDest)
The destination IP address of this route. An entry with a value of 0.0.0.0 is considered a default route. Multiple
routes to a single destination can appear in the table, but access to such multiple entries is dependent on the
table-access mechanisms defined by the network management protocol in use.
Mask (ipRouteMask)
Indicates the mask to be logical-ANDed with the destination address before being compared to the value in the
ipRouteDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value
of the ipRouteMask by determining whether the value of the corresponding ipRouteDest field belongs to a
Class A, B, or C network, and then using the appropriate mask from table 3 on page 67.
Interface (ipRouteIfIndex)
The index value which uniquely identifies the local interface through which the next hop of this route should
be reached. The interface identified by a particular value of this index is the same interface as identified by the
same value of ifIndex.
Protocol (ipRouteProto)
The routing mechanism via which this route was learned. Inclusion of values for gateway routing protocols is
not intended to imply that hosts must support those protocols.
• unknown(0)
• local(1)—Added by the DACS to support an interface. For example, adding a route for a new dial-in user.
• user(2)—Added by an administrator on the IP Routing Information table or via SNMP management tools.
• dspf(3)—Not currently implemented.
• rip(4)—Learned via reception of RIP packet.
• icmp(5)—Learned via reception of ICMP packet.
• radius(6)—Provided in RADIUS response packet.

Seconds Since Updated (ipRouteAge)
The number of seconds since this route was last updated or otherwise determined to be correct.
Tag (RouteTag)
An identifier associated with the route. This can have different meanings depending on the protocol. For exam-
ple, this gives the tag that was passed with a learned RIP route.
Gateway (RouteGateway)
Specifies the IP address to which the packets should be forwarded.
Cost (RouteCost)
This is the cost of the route as defined by RIP standards. Cost is sometimes considered to be number of hops.
A cost of 16 is considered to be infinite. A cost can be given to user-entered routes so their preference in rela-
tion to learned routes can be calculated.
State (RouteState)
Defines the state which a route may be in during its lifetime.
• invalid(1)—This setting deletes the route.
• active(2)—A valid route is in use.
• nopath(3)—No route is available to the specified gateway. The gateway is not known to local networks.
• agedout(4)—Invalid route (soon to be removed).
• costly(5)—A valid route, but not in use because of it’s higher cost.
Address Translation Information
The IP address translation table window (see figure 27) contain the IP address to physical address equivalences.
Some interfaces do not use translation tables for determining address equivalences (for example, DDN-X.25
uses an algorithmic method)—if all interfaces are of this type, then the Address Translation table is empty (zero
entries).

Interface (ipNetToMediaEntry)
Each entry contains one IP address to physical address equivalence.

Physical (ipNetToMediaPhysAddress)
The media-dependent physical address.
Type (ipNetToMediaType)
The type of mapping. Setting this object to the value invalid(2) has the effect of invalidating the corresponding
entry in the ipNetToMediaTable. That is, it effectively disassociates the interface identified with said entry
from the mapping identified with said entry. It is an implementation-specific matter as to whether the agent
removes an invalidated entry from the table. Accordingly, management stations must be prepared to receive
tabular information from agents that corresponds to entries not currently in use. Proper interpretation of such
entries requires examination of the relevant ipNetToMediaType object.

T1/E1 DACS Administrators’ Reference Guide
Introduction
Transmission Control Protocol (TCP) is in the Transport layer of the OSI model and sits on top of IP. It is one
of the more widely used protocols among the TCP/IP suite. The TCP subsystem web pages of the 2604
DACS provides management and statistical information on TCP. Detailed information regarding the SNMP
MIB variables may be downloaded from RFC1213: Management Information Base for Network Management
of TCP/IP-based internets: MIB-II.
Click on TCP under the Configuration Menu to display the TCP main window (see figure 28) to monitor TCP
statistics.

Retransmit-Timeout Algorithm (tcpRtoAlgorithm)
The algorithm that determines the timeout value used for retransmitting unacknowledged octets.
Retransmit-Timeout Minimum (tcpRtoMin)
The minimum value permitted by a TCP implementation for the retransmission timeout, measured in milli-
seconds. More refined semantics for objects of this type depend upon the algorithm used to determine the
retransmission timeout. In particular, when the timeout algorithm is rsre(3), an object of this type has the
semantics of the LBOUND quantity described in RFC 793.
Retransmit-Timeout Maximum (tcpRtoMax)
The maximum value permitted by a TCP implementation for the retransmission timeout, measured in milli-
seconds. More refined semantics for objects of this type depend upon the algorithm used to determine the
retransmission timeout. In particular, when the timeout algorithm is rsre(3), an object of this type has the
semantics of the UBOUND quantity described in RFC 793.

Maximum Connections (tcpMaxConn)
The limit on the total number of TCP connections the entity can support. In entities where the maximum
number of connections is dynamic, this object should contain the value -1.
Active Opens (tcpActiveOpens)
The number of times TCP connections have made a direct transition to the SYN-SENT state from the
CLOSED state.
Passive Opens (tcpPassiveOpens)
The number of times TCP connections have made a direct transition to the SYN-RCVD state from the LIS-
TEN state.
Attempt/Fails (tcpAttemptFails)
The number of times TCP connections have made a direct transition to the CLOSED state from either the
SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct
transition to the LISTEN state from the SYN-RCVD state.
ESTABLISHED Resets (tcpEstabResets)
The number of times TCP connections have made a direct transition to the CLOSED state from either the
ESTABLISHED state or the CLOSE-WAIT state.
Current ESTABLISHED (tcpCurrEstab)
The number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT.
Total Received (tcpInSegs)
The total number of segments received, including those received in error. This count includes segments
received on currently established connections.
Total Sent (tcpOutSegs)
The total number of segments sent, including those on current connections but excluding those containing
only retransmitted octets.

TCP (Details)
From this screen you can view port details for remote and local TCP connections (see figure 29).
Figure 29. TCP Details window
Local Port (tcpConnLocalPort)
The local port number for this TCP connection.
Remote Address (tcpConnRemAddress)
The remote IP address for this TCP connection.
Remote Port (tcpConnRemPort)
The remote port number for this TCP connection.
State (tcpConnState)
The state of this TCP connection. The only value which may be set by a management station is dele-
teTCB(12). Accordingly, it is appropriate for an agent to return a ‘badValue’ response if a management station
attempts to set this object to any other value.
If a management station sets this object to the value deleteTCB(12), Transmission Control Block, then this has
the effect of deleting the TCB (as defined in RFC 793) of the corresponding connection on the managed node,
resulting in immediate termination of the connection. As an implementation-specific option, a RST segment
may be sent from the managed node to the other TCP endpoint (note however that RST segments are not sent
reliably).

Introduction
The RIP Version 2 main window (see figure 31) describes routing information as defined by the Routing Infor-
mation Protocol (RIP). All object identifiers described in this chapter comply with those contained in RFC
1724: RIP Version 2 MIB Extension.
Figure 31. RIP Version 2 window
Click on RIP Version 2 under the Configuration Menu to display the RIP Version 2 main window.
RIP Version 2 main window
The RIP Version 2 window describes routing information as defined by the Routing Information Protocol
(RIP). The window also contains the following links:
• Statistics—Clicking on the Statistics link displays the RIP Version 2 Status window (see “RIP Version 2
(Statistics)” on page 87). In this window you can view each subnet IP address, Bad Packets, Bad Routes,
Sent Updates, and Status.
• Address (xxx.xxx.xxx.xxx)— After adding a RIP address, click on the IP Address under the Address column
to display the RIP Version 2 Configuration window. You can modify the configuration here. (see “RIP Ver-
Route Changes Made (rip2GlobalRouteChanges)
The number of route changes made to the IP Route Database by RIP. This does not include the refresh of a
route's age.
Responses Sent (rip2GlobalQueries)
The number of responses sent to RIP queries from other systems.
Adding a RIP address
Do the following:
1. Enter the IP network address of the interface on the 2604 DACS that you want to enable RIP. This will
be the LAN IP address, in other words, the IP address of the 2604. This is not the IP address of the device
you want to direct RIP packets to.

T1/E1 DACS Administrators’ Reference Guide
Domain (rip2IfConfDomain)
Value inserted into the Routing Domain field of all RIP packets sent on this interface.
Authentication Type (rip2IfConfAuthType)
The type of Authentication used on this interface.
• noAuthentication (1)
• simplePassword (2)
Authentication Key (rip2IfConfAuthKey)
This value is used as the Authentication Key whenever Authentication Type (rip2IfConfAuthType) has a value
other than noAuthentication(1). A modification of Authentication Type does not change the value of Authenti-
cation Key. If the Authentication Key string is shorter than 16 octets, it will be left justified, then padded to 16
octets with nulls (0x00) on the right.
Reading this object always results in an octet string of length zero. Authentication may not be bypassed by
reading the MIB object.
Send (rip2IfConfSend)
Send is what the router sends on this interface. ripVersion 1 implies sending RIP updates compliant with RFC
1058. There are four options, doNotSend(1), ripVersion1(2), rip1Compatible(3), and ripVersion2(4).
rip1Compatible implies broadcasting RIP-2 updates using RFC 1058 route subsumption rules. ripVersion2
implies multicasting RIP-2 updates. ripV1Demand indicates the use of Demand RIP on a WAN interface
under RIP Version 1 rules. ripV2Demand indicates the use of Demand RIP on a WAN interface under Version
2 rules.
• doNotSend (1)
• ripVersion1 (2)
• rip1Compatible (3)—rip1Compatible implies broadcasting RIP-2 updates using RFC 1058 route sub-
sumption rules
• ripVersion2 (4)—ripVersion2 implies multicasting RIP-2 updates
Receive (rip2IfConfReceive)
This indicates which version of RIP updates are to be accepted. Note that rip2 and rip1OrRip2 implies recep-
tion of multicast packets.
• rip1 (1)
• rip2 (2)
• rip1OrRip2 (3)
• doNotRecieve (4)
Metric (rip2IfConfDefaultMetric)
This variable indicates the metric that is to be used for the default route entry in RIP updates originated on this
interface. A value of zero indicates that no default route should be originated; in this case, a default route via
another router may be propagated.

PCs running on a Microsoft Windows local area network. The system administrator assigns a range of IP
addresses to DHCP and each client PC on the LAN has its TCP/IP software configured to request an IP
address from the DHCP server. The request and grant process uses a lease concept with a controllable time
period. More information can be found in the Microsoft documentation on NT Server.

T1/E1 Link Activity main window
The T1/E1 Link Activity window has three main sections that display the following T1/E1 parameters:
• Line Status—Shows the configuration of the T1/E1 Interface and service provided on each user time slot.
• Near End Line Statistics—Show error statistics collected from the near-end of the T1/E1 line.
• Far End Line Statistics—Show statistics collected from the far-end T1/E1 line. Far End Line Statistics can be
used by devices that support the facility data link (FDL)
Link (dsx1LineIndex)
This object identifies a DS1 Interface on a managed device. If there is an ifEntry directly associated with this
DS1 interface, it must have the same value as ifIndex. Otherwise, the value exceeds ifNumber, and is assigned a
unique identifier by following this rule: inside interfaces (equipment side) with even numbers and outside
interfaces (network side) with odd numbers.
Type (dsx1LineType)
This variable indicates the type of DS1 line using the circuit. The circuit type determines the bits-per-second
rate that the circuit can carry and how it interprets error statistics. The values are as follows:
• dsx1ESF—Extended Superframe DS1
• dsx1D4—AT&T D4 format DS1
• dsx1E1—Based on CCITT/ITU G.704 without CRC
• dsx1E1-CRC—Based on CCITT/ITU G.704 with CRC
Circuit ID (dsx1CircuitIdentifier)
This is the transmission vendor’s circuit identifier. Knowing the circuit ID can be helpful during
troubleshooting.

Line Status (dsx1LineStatus)
This variable indicates interface line status. It contains loopback, failure, received alarm and transmitted alarm
information. If any condition other than No Alarms exists, you can click on the Alarms Present link to view
Figure 43. Line Status Alarms window
The alarms currently present on the line will be indicated by the ACTIVE label next to the alarm type.
Failure States
The following failure states are reported in the dsx1LineStatus object. The items listed in this section comprise
those contained in RFC 1406—Definitions of Managed Objects for the DS1 and E1 Interface Types.
Far End Alarm Failure
Far End Alarm failure is also known as a Yellow Alarm in the T1 case or Distant Alarm in the E1 case.
For D4 links, the Far End Alarm failure occurs when bit 6 of all channels has been zero for at least 335 ms. The
alarm is cleared when bit 6 of at least one channel is non-zero for a period T, where T is usually less than 1 sec-
ond and always less than 5 seconds. The Far End Alarm failure is not declared for D4 links when a Loss of Sig-
nal is detected.
For ESF links, the Far End Alarm failure is declared if the Yellow Alarm signal pattern occurs in at least 7 out of
10 contiguous 16-bit pattern intervals. The alarm is cleared when the Yellow Alarm signal pattern has not
occurred for 10 contiguous 16-bit signal pattern intervals.
For E1 links, the Far End Alarm failure is declared when bit 3 of time-slot zero is received set to 1 on two con-
secutive occasions. The Far End Alarm failure is cleared when bit 3 of time-slot zero is received set to zero.

Alarm Indication Signal (AIS) Failure
The Alarm Indication Signal failure is declared when an AIS defect is detected at the input and the AIS defect
still exists after the Loss Of Frame failure (which is caused by the unframed nature of the all-ones signal) is
declared. The AIS failure is cleared when the Loss Of Frame failure is cleared.
Loss Of Frame Failure
For T1 links, the Loss Of Frame failure is declared when an OOF or LOS defect has persisted for T seconds,
where 2 ≤ T ≤ 10. The Loss Of Frame failure is cleared when there have been no OOF or LOS defects during
a period T where 0 ≤ T ≤ 20. Many systems will perform hit integration within the period T before declaring or
clearing the failure (for more information, see TR 62411 [16]).
For E1 links, the Loss Of Frame Failure is declared when an OOF defect is detected.
Loss Of Signal Failure
For T1, the Loss Of Signal failure is declared upon observing 175 +/- 75 contiguous pulse positions with no
pulses of either positive or negative polarity. The LOS failure is cleared upon observing an average pulse density
of at least 12.5% over a period of 175 75 contiguous pulse positions, starting with the receipt of a pulse.
For E1 links, the Loss Of Signal failure is declared when greater than 10 consecutive zeroes are detected (see
O.162 Section 3.4.4).
Loopback Pseudo-Failure
The Loopback Pseudo-Failure is declared when the near end equipment has placed a loopback (of any kind) on
the DS1. This allows a management entity to determine from one object whether the DS1 can be considered to
be in service or not (from the point of view of the near end equipment).
TS16 Alarm Indication Signal Failure
For E1 links, the TS16 Alarm Indication Signal failure is declared when time-slot 16 is received as all ones for
all frames of two consecutive multiframes (see G.732 Section 4.2.6). This condition is never declared for T1.
Loss Of MultiFrame Failure
The Loss Of MultiFrame failure is declared when two consecutive multiframe alignment signals (bits 4 through 7
of TS16 of frame 0) have been received with an error. The Loss Of Multiframe failure is cleared when the first cor-
rect multiframe alignment signal is received. The Loss Of Multiframe failure can only be declared for E1 links
operating with G.732 [18] framing (sometimes called Channel Associated Signalling mode).
Far End Loss Of Multiframe Failure
The Far End Loss Of Multiframe failure is declared when bit 2 of TS16 of frame 0 is received set to one on two
consecutive occasions. The Far End Loss Of Multiframe failure is cleared when bit 2 of TS16 of frame 0 is
received set to zero. The Far End Loss Of Multiframe failure can only be declared for E1 links operating in
Channel Associated Signalling mode.

This variable contains the transmission vendor’s circuit identifier, for the purpose of facilitating
troubleshooting.
Line Type (dsx1LineType) Type (dsx1LineType)
This variable indicates the type of DS1 Line implemented on this circuit. The type of circuit affects the num-
ber of bits per second that the circuit can reasonably carry, as well as the interpretation of the usage and error
statistics. The values, in sequence, are:
• other(1) —Link is disabled
• dsx1ESF(2)—Extended Superframe DS1
• dsx1D4(3)—AT&T D4 format DS1

• dsx1E1(4)—Based on CCITT/ITU G.704 without CRC
• dsx1E1-CRC(5)—Based on CCITT/ITU G.704 with CRC
Line Coding (dsx1LineCoding)
This variable describes the type of Zero Code Suppression used on the link, which in turn affects a number of
its characteristics.
• dsx1JBZS(1)—Jammed Bit Zero Suppression, in which the AT&T specification of at least one pulse every 8
bit periods is literally implemented by forcing a pulse in bit 8 of each channel. Thus, only seven bits per
channel, or 1.344 Mbps, is available for data. This feature is not currently implemented.
• dsx1B8ZS (2)—The use of a specified pattern of normal bits and bipolar violations which are used to
replace a sequence of eight zero bits.
• dsx1HDB3(3)
• dsx1ZBTSI(4)—May use dsx1ZBTSI, or Zero Byte Time Slot Interchange. This feature is not currently
implemented.
• dsx1AMI(5)—Refers to a mode wherein no zero code suppression is present and the line encoding does not
solve the problem directly. In this application, the higher layer must provide data which meets or exceeds
the pulse density requirements, such as inverting HDLC data.
• other(6)—This feature is not currently supported.
Receive Equalizer (linkRxEqualizer)
This variable determines the equalization used on the received signal. Long haul signals should have the equal-
ization set for more. Short haul signals require less equalization.
• linkRxEqualizerOff(1)
• linkRxEqualizerOn(2)
Line Build Out (linkLineBuildOut)
This variable is used in T1 applications to adjust the T1 pulse shape at the cross connect point. Select the pulse
strength needed to minimize distortion at the remote T1 receiver end. The default is t1pulse0dB, which
should be adequate for most situations.
• triState(0)
• e1pulse(1)
• t1pulse0dB(2)—Strong pulse amplitude.
• t1pulse-7dB(3)—Medium pulse amplitude.
• t1pulse-15dB(4)—Weak pulse amplitude.
Yellow Alarm Format (linkYellowFormat)
This variable identifies which standard will be used to transmit and identify the Yellow Alarm.
• link YellowFormatBit2(1)—Bit-2 equal zero in every channel
• YellowFormatDL(2)—FF00 pattern in the Data Link

• YellowFormatFrame12FS(3)—FS bit of frame 12
FDL (dsx1FDL)
This describes which implementation of FDL is being used, if any. FDL applies only to T1 circuits.
• other(1)—Indicates that a protocol other than one following is used.
• dsx1Ansi-T1-403(2)—Refers to the FDL exchange recommended by ANSI.
• dsx1Att-54016(3)—Refers to ESF FDL exchanges.
• dsx1Fdl-none(4)—Indicates that the device does not use the FDL.
Test Settings
This portion of the WAN Circuit Configuration window contains information described in the following
sections.
Force Yellow Alarm (linkYellowForce)
This variable identifies which standard will be used to transmit and identify the Yellow Alarm.
• linkYellowAuto—Do not force the transmission of a yellow alarm. But, yellow alarm may be automatically
transmitted.
• linkYellowOn—Force the transmission of a yellow alarm even if the received signal is in frame.
• linkYellowDisable—Do NOT transmit a yellow alarm even if the received signal is out of frame.
Loopback Config (dsx1LoopbackConfig)
This variable represents the loopback configuration of the DS1 interface. Agents supporting read/write access
should return badValue in response to a requested loopback state that the interface does not support. The val-
ues mean:
• dsx1NoLoop—Not in the loopback state. A device that is not capable of performing a loopback on the
interface shall always return this as it's value.
• dsx1PayloadLoop—The received signal at this interface is looped through the device. Typically the received
signal is looped back for retransmission after it has passed through the device's framing function.
• dsx1LineLoop—The received signal at this interface does not go through the device (minimum penetra-
tion) but is looped back out.
• dsx1OtherLoop—Loopbacks that are not defined here.
Send Code (dsx1SendCode)
This variable indicates what type of code is being sent across the DS1 interface by the device. The values mean:
• dsx1SendNoCode—Sending looped or normal data
• dsx1SendLineCode—Sending a request for a line loopback
• dsx1SendPayloadCode—Sending a request for a payload loopback
• dsx1SendResetCode—Sending a loopback termination request
• dsx1SendQRS—Sending a Quasi-Random Signal (QRS) test pattern

Line Status Alarms web page. The “Line Status Alarms” page gives the status of the T1/E1 WAN port. This is
the same web page seen under the T1/E1 Link Activity page in the T1/E1 Link subsytem.
Under each WAN port column group are four columns named Slot, Device, Port #, and Slot #.
Slot
Slot refers to the time slot in the T1/E1 port. Whether you have chosen T1 or E1, all 31 channels will be dis-
played although in T1, only those numbered 1–24 are applicable.
Device
Device (daxWAN0DeviceType, daxWAN1DeviceType, daxWAN2DeviceType, daxWAN3DeviceTyp)
refers to the device type to which the WAN slot connects. The device type options are:
• open(0)
• t1-e1(1)
Note There are four variables for Device Type where
daxWAN0DeviceType applies to those in WAN Port 1. Similarly
daxWAN1DeviceType applies to those in WAN Port 2. Likewise for
the others.
Port #
Port # (daxWAN0DeviceNumber, daxWAN1DeviceNumber, daxWAN2DeviceNumber,
daxWAN3DeviceNumber) refers to the port number of the Device Type in the second sub-column. Since there
are only four WAN ports, the Device Number (Port #) may be chosen from port1(1) to port4(4).
Slot #
Slot # (daxWAN0DeviceSlot, daxWAN1DeviceSlot, daxWAN2DeviceSlot, daxWAN3DeviceSlot) refer to the slot
number (or time slot) of the Device. For t1-e1 Device Types, Slot# may vary from 1 to 31.
