1. INTRODUCTION
Thank you for choosing the VC-412 VDSL Managerial Switch for your MDU Solution.
PLANET has been on the forefront of VDSL (Very High Bit-Rate Digital Subscriber Line)
technologies since their inception, and will always strive to create quality, cost-effective
solutions for VDSL users and installers.
Fiber all the way to the home (FTTH) is very expensive therefore another alternative is a
combination of fiber cables to Optical Network Units (ONUs) or otherwise called the Fiber
to the Neighborhood (FTTN) as the connection point between fiber and existing or new
copper wire. One of the enabling technologies for FTTN is Very high rate Digital
Subscriber Line, or VDSL. In simple terms, VDSL transmits high speed data over short
reaches of twisted-pair copper telephone lines, with a range of speeds depending upon
actual line length.
By choosing the VC-412 VDSL Managerial Switch, you have enabled your network to
have the superb speed and manageability. VC-412 offers 12 VDSL ports, 12 POTS/ISDN
ports and 4 Ethernet ports for your VDSL solutions.

2. INSTALLATION
2.1 Connecting VC-412
The VC-412 has the ability to provide up to 12 remote VDSL connections. The VC-412
serves as a VDSL Managerial Switch, it can connect up to 12 sets of PLANET remote
VDSL modems such as the VC-101S.
The VC-412 connects to the PBX through the POTS/ISDN ports to provide telephone
services to the remote ends. The VC-412 VDSL ports then connect to the remote VDSL
modems via telephone wires with a maximum distance up to 1.5 km.
The VC-412 takes approximately 15 seconds to start, therefore when connecting the
VC-412 to a remote modem such as the VC-101S, it will take 15 seconds for link to be
established.
VC-412 Ethernet Port-D can serve as an uplink or a regular Ethernet port on, when the
Uplink button is pressed down it serve as an uplink port, when the Uplink button is
released it serve as a regular Ethernet port. Hence when connecting the VC-412 to
WAN via regular Cat. 5 cable on Port-D press down the Uplink button.

2.2 Console Port Setup
7
Download from Www.Somanuals.com. All Manuals Search And Download.
VC-412 User’s Manual
The VC-412 contains a powerful management interface accessible through the Console
Port. This section will discuss connecting to the switch through Console Port or Telnet.
For connection to the VC-412 via the console port, you must use the included DB-9 to
DB-9 cable.
Once out of the box and powered on, you must use the Console Port to setup the switch
core settings. Some of the basic settings include:
• Switch Management Module IP Address
• Gateway Address
• Subnet Mask
• Password Settings
To setup Console connection, use the DB9-to-DB9 cable to connect the VC-412 Console
port to PC COM port.
Once the VC-412 Console port is connected to the PC COM port, start any terminal
application. Subsequently, configure the terminal application settings with following
variables:
Baud Rate
Data Bits
Parity
Stop Bits
Flow Control
19200bps
8
None
1
None
Once connected, password authentication is required. The default password is admin.
Console and Telnet share similar interfaces, the main difference between them is that
Console connects to the Switch directly through a cable. Telnet connects to the switch
remotely via an IP Address. Therefore, to use Telnet to access to the Switch, you will first
need to assign a valid IP address to the Switch through the Console. Otherwise use the
factory default IP address listed in the Appendix A. Web-Based interfaces also required
the same Switch IP, however the interfaces are different from Console and Telnet. (This
will be discussed in the Chapter 3.)
To assign an IP address to the Switch:
1. Select Management Configuration option from the Main Menu.
2. Select System Configuration option from the Submenu.
3. Select IP Address option.
4. Enter valid IP address.
5. When setting up Gateway Address and Subnet Mask repeat Step 2 and select
the appropriate option in the menu. Refer to your network administrator for your
appropriate Gateway Address and Subnet Mask.

VC-412 User’s Manual
.
Once you have assigned a valid IP address to the Switch, proceed to chapter 4 for an
explanation of the menu systems and commands.
2.3 Telnet Setup
Once you have setup the switch IP address via the Console Port, you are ready to access
the management functions from any station on your network via Telnet. To connect,
simply start your telnet client and enter the address you configured into the switch
(Device IP Address). Below you can see an example of using the standard Windows®
Telnet client. Before using Telnet, you must first know your Switch device IP address. The
IP should have been set earlier in the Console setup section. If the IP address has not yet
been set, refer to the quick installation guide.
For Windows 95/98/NT/2000/XP:
A. Press on Start Menu, then on RUN, type in telnet and the device IP address. For
example, if the IP address is 192.168.0.1, type “telnet 192.168.0.1” and hit enter.
B. Connection will initiate and you will be prompt to enter password.
C. The default password is admin, unless it has been changed previously.
Once you have logged into the switch, proceed to the next section for an explanation on
issuing ICD commands.

this is an easy method, you do not have the full flexibility and control granted as you
would under Telnet or Console. The HTTP interface allows basic functions, such as Reset
Unit Counters. However, we recommend users to perform modifications through Console
or Telnet interfaces. The Web browser interface also allows VDSL ports and Ethernet
(trunk) ports monitoring, providing feedback on network statuses.
To log on to the VC-412 via HTTP you must first provide the IP address to the VC-412.
The IP address should have been set earlier in the Console setup section. If your IP has
not been set, please refer to the Console port section or the Defaults section in the
Appendix A.
Note: Please use MS Internet Explorer 5.5 or above to access to the VDSL Web page.
A. Launch your Web browser.
B. Enter the corresponding VDSL Managerial Switch IP Address in the address
field and press Enter.
C. You will be able to select your language preferences in the upper-right corner.

Note:
There are three VLAN modes: ON, OFF and USER DEFINED. When the VLAN mode is
OFF, all VDSL and Ethernet ports can communicate each other. When VLAN
mode is ON, the switch will automatically create the following 13 VLANs. All
VDSL ports cannot communicate each other and can only connect to port A and D.
When VLAN mode is USER DEFINED, you can use VG command to create your
own VLAN settings.
VLAN settings when VLAN is ON:
Group 01 - 1,A,D

5.3 Setting VLAN Functionality
The VLAN function offers security and flexibility of controlling each port’s access to one
another. This feature is useful in MDU and hotel situations where you would not want
each computer to be able to “see” all other computers connected to the VC-412. However,
in some situation you may need to have a few ports with the capability of communicating
with one another. Such situations may arise for sharing files, collaboration software,
faster multi-player gaming, etc.
Activating the VLAN function allows each port to be individualized, and
34

VC-412 User’s Manual
non-communicative to the other ports on the VC-412 in regards to local traffic.
Deactivating VLAN allows the switch to act as a normal Ethernet VC-412, by passing
along multicast and broadcast traffic to each port. Disabling this feature would be useful
when installing the VC-412 in office settings and for file/print sharing.
Within the ICD command interface or web interface, you can turn the VLAN function on or
off. In ICD simply type “VO” to activate the VLAN function, and “VF” to deactivate the
VLAN function.
Note that when VLAN is on, group 1 to 12 is categorized by one VDSL port and two
Ethernet ports (port-A and port-D). Hence, Ethernet port-B and port-C will not grant any
bandwidth to VDSL ports. Therefore, trunking can be only done via port-A and port-D.
Turning VLAN off will enable all four Ethernet ports accessible to all VDSL ports, however,
it sometimes causes the switch to halt since the Ethernet port-B and port-C are designed
for different purposes.
VC-412 also allows VLAN Grouping, which enables user to define ports to communicate
with each other, while remaining isolated from the other ports (outside the defined range)
traffic. The VC-412 supports up to 16 different groupings, and can only be set within the
ICD Command Interface. The ICD Command for VLAN Grouping is VG.
The command line format is as follow:
[VG] [Group]-[port1,…,portN]
Syntax
Description
[VG]
Command string.
[Group]
Group number, from 01 to 16.
Command string
[-]
List of ports to be included in the group
separated by commas, the VDSL ports are
numbered with 01 to 12 and Ethernet ports are
ordered from A to D.
[port1,…,portN]
Important: Same ports can exist in different groups, however each invocation of the VG
for the same group will overwrite the previously saved list for that group.
Examples:
To group VDSL port-1, port-2, and Ethernet port-A together you will need to issue the
following commands:
35

VG 1-1,2,A
Add port-4, port-8 and port-D to group 1 from previous example
VG 1-1,2,4,8,A,D
Delete port-2 and port-8, port-A of group 1 from previous example
VG 1-1,4,D
Empty group 1
VG 1-
Add port-1, port-3, port-6, port-10, port-B, port-C, port-D to group 5
VG 5-1,3,6,10,B,C,D
You can verify the VLAN groups through the “V” command.
5.4 VDSL Command
For VDSL local and remote connections to establish, local switch and remote modem
must adjust to a corresponding rate. However if the distance between VC-412 and the
remote VDSL modem is too far then connection may not establish with high stream rates.
Therefore the VC-412 VDSL Managerial Switch and the VDSL remote modem are factory
set to the lowest stream rate; 4 Mbps downstream and 1 Mbps upstream. Once
connection between the VC-412 and the remote modem is established the switch will try
to adjust the stream rate to the next higher speed mode. If the next new stream rate failed
then it will go back to speed level-A (LWD mode) and progressively adjust to the last
highest effective rate. It will take approximately 10 seconds for the VC-412 to recalibrate
to LWD mode. This is called auto-speed.
In some situations higher stream rate is reachable but line quality might be poor due to
environmental factors or/and bad line conditions. In such circumstances, administrators
will want to define the maximum steam rate to a more stable rate. For example, if you
want to define the maximum speed on port-5 to speed level-B (5 Mbps symmetric) then
you can issue LR 5-B in the ICD command interface. Doing so will preset port-5
maximum speed to level-B therefore it will establish connection from speed level-A and if
succeeded, it will progress to level-B and stays at that point if it is reachable.
You can also manually set the port speed for testing purposes. To experiment, you must
first manually set the remote modem to a desired speed and then set the speed on the

VC-412 User’s Manual
connected port of the VC-412 to the same speed. The reason you need to set the speed
on the remote modem first is when you adjusts the speed on the remote modem,
connection with end since speeds on both sides will be different. After setting the VC-412
port to the same speed as the remote modem, connection will re-establish if it is within
the distance limitation. For example if you want to test the quality of transmission with the
stream rate speed at speed level-B (5 Mbps symmetric). You will enter the following
commands in the ICD command interface.
RT 10-B
Connection will end
LT 10-B
Connection will re-establish if within the range.
If connection does not establish with new speed level, reset the switch and wait
approximately 47 seconds for the switch and the remote modem to recalibrate.
5.5 Port Command
The “P” command displays all the VDSL ports status including its speed and speed mode.
AUT represents Auto-speed mode, PRE represents preset speed and MAN represents
manual set speed. At the speed column you will see a representation of preset speed and
the current speed of each port. The numerator is preset speed (“*” means not applicable)
and the denominator is current speed. Please refer to the ICD Command Index table for
reference.

APPENDIX B – UPDATE VC-101S FIRMWARE TO
R4.5 REMOTELY THROUGH VC-412
The purpose of this appendix is to upgrade older versions of VC-101 (R2 or R4) into the
newest version (R4.5) remotely through VC-412. The new version will contain
auto-speed function which can seek the maximum transmission speed automatically.
The default speed of version R4.5 VC-412 Mbps downstream/1 Mbps upstream but the
default speed of version R2 is 11 Mbps symmetric and default speed of version R4 is 15
Mbps downsteam/17 Mbps upstream. Therefore you will need to adjust both VC-412 and
VC-101S to a complementary speed in order to establish link. You can perform these
procedures remotely via VC-412 console or telnet.
1. Login to the VC-412 via console or telnet.
2. Access to the ICD Command interface.
3. Adjust the speed on VC-412 to the remote modem’s speed with the following
command:
LT <port>-<speed of remote modem>
For example if port-2 is connected to a version R4 VC-101S the command would be:
LT 2-Q
If it is connected to a version R2 VC-101S then use the command would be:
LT 2-P
Note: Connection will establish after issue above command. Please note this setting

4. Now set the remote modem’s speed to A which is the LWD mode.
Command Description: RT <port>-<LWD speed mode>
Command: RT 2-A
Important: Setting the remote modem’s speed first is very important since connection
will end once the remote modem’s speed differs from the local switch.
5. Now set the speed of VC-412 back to LWD mode.
Command Description: LT<port>-<LWD speed mode>
Command: LT 2-A
Note: Connection will re-establish.
6. Save remote modem’s setting so it will not be lost upon power cycling.
Command Description: SR <port>
Command: SR 2
7. Adjust the VC-412 back to auto-speed mode.
