Chapter 2 Installation
2.1 Rear Panel Connectors
There are four connectors on the rear panel. To make a connection with these
connectors, refer to Section.2.3.
2.2 Preparing for Installation
Make sure the following equipment is ready before installing the router.
nVT-100 Compatible Terminal –
This terminal is essential to perform the initial configuration of the router.
This is normally a terminal with a VT-100 emulation program, such as
Telix and HyperTerminal Edition5.
nConsole Port Cable –
An RS-232, DB9-to-DB9 straight-through cable is required to connect the
terminal to the device. For pin definitions, please refer to Appendix C.
nAC power adapter-
A suitable power adapter is shipped with the router. It is used to provide
the necessary power for the router’s operation.
nAn optional LAN connection cable –
To connect to the hub, use a straight-through RJ45 cable. To connect to a
PC, use a crossover RJ45 cable. Refers to Appendix C for pin definitions
of the LAN port.
nAn optional RJ11 cable –
An RJ11 cable is needed to connect the LINE port.

2.3 Installation Procedures
Figure 2-1 illustrates possible connections to the backplane connectors.
Figure 2-1Installation
Step 1 Connect the Line port to the phone line.
Step 2 Connect the LAN port to a hub with a straight-
through RJ45 cable, or
connect the router to a PC with a crossover RJ45 cable.
Step 3 Connect the Console port to the VT-
100 compatible terminal with a
RS232 straight-through cable for local management.
Step 4 Connect the Power
jack to the power cord with the shipped power
adapter cord.
Step 5 Attach the power adapter to the wall outlet or other AC source.
Step 6 After power on, the router performs a self-
test. Waiting for a few seconds
until the test is finished, the router will be ready to operate.
Caution 1: If the router fails to power on, or it
malfunctions, first verify that the
power supply is correctly connected. Then power it on again. If
the problem persists, contact our technical support engineers.
Caution 2:
Always disconnect all telephone lines from the wall outlet before
servicing or disassembling this equipment.

Chapter 3 Accessing the Router
This chapter introduces how to access and manage the router. Initial configuration
of the router is covered in Chapter 4, Initial Configuration. There are two methods
to access the router: console and Telnet. Either of these methods can be used to
access, configure, operate or monitor the router.
3.1 Access by Console
For access by console, the console PC should be installed with a standard VT-100
emulation program, such as HyperTerminal 5 or Telix. The following steps describe
how to establish the console session.
Step 1 Start a standard VT-100 program such as HyperTerminal (Ver. 5 is
recommended), or Telix in the local terminal; and select an open
com port.
Step 2 Enter the following port settings:
nBaud rate: 9600
nData bits: 8
nParity: none
nStop bit: 1
nFlow control: none
Step 3
After the session parameters are set up, as shown in Step 2, press
the ESC key.
You can start operating the router now. [General
operation procedures are described in Section 3.4.]

9
Step 4
Note:
Use the up/down-arrow
keys to select the utility item you want
and then use the right-arrow
key to enter the menu you will
configure.
To configure the router for Telnet and Web access, complete the
procedures belo
w to change the necessary parameters. If you do not
require Telnet or Web access you can go directly to step 13,
in
which case you will be using the following default values:
LAN IP address: 210.65.231.206
Read-write access password
nLogin: root
nPassword: root
Step 6 To change the LAN IP address, enter the MAIN/QC/LAN menu.
Step 7
To set WAN IP addresses, enter the ATM interface menus, e.g.,
MAIN/QC/ATM/ATM1 [Refer to Section 4.2.2 ATM Interface details].
Step 8 Hold down the Ctrl-S keys to save the settings.
Step 9 To change the passwords, enter the MAIN/CONF/SYSTEM menu.
Step 10
You can enable the console password check function in the Console
PasswordCheck field. Then, a visitor will be requested to enter the
password.
Step 11 Enter a new password for ADMINISTRATOR in the
New
Administrator Password
field and retype the password to confirm.
Step 12 Enter a new password for USER in the New User Password
field and
retype the password to confirm.
Step 13 Return to the main menu and select WRITE
to write these
configurations to the flash memory, and then reboot the system.
Step 14 In less than one minute, the sentence Press ESC key to enter
console mode configuration displays on your screen.
Note:
After changing the parameters, save them to flash memory and then
reboot the system before you quit, or you will lose the new
parameters.

10
3.2 Access by Telnet
The device permits a maximum of one ADMINISTRATOR, and two COMMON users to
telnet to the system at the same time. The following steps show the configuration.
Step 1: Telnet to the router with the LAN IP address or WAN IP address
[refer to Section 3.1, Steps 6 and 7 on setting the LAN/WAN IP
addresses]. The default LAN IP address is 210.65.231.206
Step 2: You will be requested to enter the login name and password as
follows.
Login: root
Password: ****
To have full access privileges as an ADMINISTRATOR, type root
in
the Login field, and root in the password field; or if the defaul
t
password was changed, type the password that was set in the
console session [refer to Section 3.1 Steps 9-12.]
To have read-only access as a common USER, type user
in the Login
field and user
in the password field; or if the default password was
cha
nged, type the password that was set in the console session
[refer to Section 3.1 Steps 9-12].
Step 3
The main menu should appear. The menus in a Telnet session are
the same as in the console session.

3.3 Keyboard Operations
↑The upward arrow key moves the cursor upward in the menu
↓The cursor moves downward in the menu.
←Returns to the previous menu. If you are in a leaf menu you may
need to push ^S first (to save the information)
→Skips to the next menu.
^S Hold down the Ctrl-S keys simultaneously to perform different
actions such as Save, Add, Delete and Go.
^X In the leaf menu, hold down the Ctrl-
X keys simultaneously to return
to the previous menu.
^L Hold down the Ctrl-L keys simultaneously to return to the Home
Menu
^T Hold down the Ctrl-T keys simultaneously to reset the value or
statistics counted.
^R Hold down the Ctrl-R keys simultaneously to refresh or restore the
menu.
Q Press the Qkey to stop certain actions, such as software
downloading.
Tab In the leaf menu, some configuration fields are marked, TAB. It
means you need to press the TAB key to scroll through and select
the pre-defined options.
The following backup keys can be used if your software
doesn’t support arrow keys
^W Moves the cursor upward [equal to the up arrow key]
^Z Moves the cursor downward [equal to the down arrow key]
^A Return to the previous menu [equal to the left arrow key]
^D Enter the selected item [equal to the right arrow key]

12
3.4 Menu Layout
The operating menu of the router follows a tree-structured design with three
categories: main menu, branch menu and leaf menu. You can select each menu
item by using the up, down, left and right arrow keys in the main and branch
menus. The leaf menu is used to program each parameter. The layout of a menu
includes messages, such as software version, model name, and keyboard
instructions.

3.5 Configuration Steps in Console/Telnet
This section will briefly explain the steps involved to configure your router from the
console or from Telnet. For ease of use, when describing configuration procedures in
this document, the full path name is given, e.g.,> MAIN/QC/LAN. For example, if
you want to configure the LAN interface of the router, complete the following
procedures.
Step 1:
Enter the main menu. You can verify you are in the main menu, by
checking the text at the bottom-left of the screen reads: Path>Main.
If you are not in the main menu, use the key commands as e
xplained
in Section 3.4 to access the Main Menu.

14
Step 2:
Use the up or down arrow keys to select an item. In this case, select
QC. Press the right arrow key to go to the MAIN/QC
menu. The
text at the bottom-left of the screen, should read: PATH> MAIN/QC
to
indicate the directory of the current operating menu.
Step 3:
Use the up or down arrow key to select an item. In this case, select
LAN
and press the right arrow key to enter the leaf menu. The text at
the bottom-left of the screen, should read: PATH> MAIN/QC/LAN
Step 4:
Enter a parameter in each field. For fields that include the word:
TAB, e.g., Network Type (TAB)
, press the TAB key to select a
parameter from the pre-
defined values. Then save the settings in
RAM by holding down the Ctrl-S keys.
