Chapter 1

Getting Started

I. Overview

X8122r is multi-mode ADSL Router, compliant with ANSIT1.413
Issue 2, ITU G.992.1 (G.dmt) Annex A/B, G.992.2 (G.lite). X8122r
provides high-speed Internet access via one WAN port over ATM over
ADSL, and also connects to a corporate network via four-10/100BaseT
Ethernet ports. Interchangeable between both routing and bridging,
X8122r offers convenient configuration and management. X8122r
allows service providers to deploy ADSL rapidly over existing wire
infrastructure (POTS or ISDN line).

X8122r

and the other end to the ADSL wall outlet.

2. Use a RJ-45 cable to connect one end to the Ethernet port of
X8122r, and the other end to the LAN or a PC with an Ethernet
adapter installed.

3. Use a 9-pin RS-232 cable to connect the Console port to a
serial port of a terminal such as PC with data terminal
emulation software (Hyper Terminal) installed, in order for local
management.

4. Plug in the AC adapter to the AC power socket, and the other

VI. Management

X8122r supports simple, flexible, and easy-to-operate methods for
management purposes. X8122r can be managed via the following
paths:

 Console port – use the RS-232 cable for connecting

X8122r to a console terminal or a PC running a terminal
emulation program, such as Hyper Terminal. (For further

details, See Chapter 1: IX Console Setup)

 Local Ethernet Port (Telnet) – connect the Ethernet port to

your local area network or to directly to a PC. “Telne t”
X8122r from any workstation in the LAN. The default local
Ethernet IP address is “192.168.1.1”.

 Local Ethernet Port (Web Browser) – connect the Ethernet

port to your local area network or directly to a PC. Launch
your web browser and enter default local Ethernet IP
address “192.168.1.1” into the address bar.

 ADSL Port from Remote Site – while the ADSL connection

is in service, you may remotely “Telnet” X8122r from a
workstation connected to the CO equipment.

Note: As operating an ADSL device requires technical know-how and
experience. It is recommended that only qualified technical staffs
manage X8122r. Therefore, a password authentication is required when
you enter the web interface. To obtain the password, see the Default
Values section.

VIII. Software Upgrade

You may easily upgrade X8122r embedded software by obtaining
the compressed upgrade kit from the service provider then following
the steps:

1. Extract the ZIP file for updated firmware.

2. Connect X8122r via one of the four local ports or remote ADSL
link. Make sure that X8122r 4 port IP address and your terminal
are properly configured, then you can successfully “ping”
X8122r. The default local IP address is 192.168.1.1.

3. Under DOS prompt, execute FTP command “open <IP
address of X8122r>”, then input user name and password.

4. Execute upload command “put tepatch.bin“.

5. This upgrading process might last as long as 60 seconds.

6. Then reboot X8122r with new software.

Note 1: X8122r software may also be upgraded through the web interface.
See Chapter 2: G. Admin, 3. Image Upgrade

Note 2: Strictly maintain stable power to X8122r while upgrading its
software. If the power fails during the upgrading process, contents in the
memory could be destroyed, and the system may hang. In such a case,
you must call the dealer or system integrator for repairs.

Web Interface Management

I. Overview

The Web management is provided in order to manage the ADSL
device as easily as possible. It provides a very user-friendly
configuration and graphical interface through a Web based platform.
You can configure a bridge or a router, as you feel appropriate. In the
section below, each configuration item is described in detail.

II. Preparation

1) Please refer the hardware installation procedure to install
modem.

2) You should configure the PC to the same IP subnet as the
modem.
For example: The modem: 192.168.1.1

Your PC: 192.168.1.x

3) Let your PC access the modem, and make sure that the
PING function is working properly. The default IP address of
this modem could be found in the default settings section.

4) Open the Web browser (Internet explorer or Netscape), enter
the default IP address “192.168.1.1” for the website address
to access the web management page.
