Status

DSL Connection

This page shows the DSL line connection status as below:

Line Mode

:

The ADSL Router supports multi-mode standard.

DS (Downstream)/US (Upstream) Speed

: The downstream/upstream speed of the DSL line.

DS/US Latency

:

Displays whether a fast or interleaved latency path is specified.

Trellis coding

:

Indicates trellis coding is enabled or disabled. Trellis coding is a method of providing better

performance in a noisy environment. It helps to transmit at faster line rates with lower error rates,

thus providing a faster overall throughput in a moderately noisy environment.

Line Attenuation

: Indicates the signal attenuation caused by line length. It increases with line length and frequency

and decreases as wire diameter increases.

Noise Margin

:

Signal to noise ratio. The ratio of good data (signal) to bad (noise) on the line that is expressed in

decibels (dB).

Loss of Signal /Frame

: Indicates the loss of signals or frames detected.

CRC Error

:

Cyclic Redundancy Checksum generated.

Line Up Count

:

The number of times that you connect to.

Line Up Time

:

The duration time of the line connecting.

Error Second

:

The accumulated seconds of the seconds during which packet error message occur.

System

Up Time

: The time from system startup.

WAN Connection

This page shows all the ATM PVC interfaces you defined. For each ATM PVC interface, it shows the parameter you

defined for ATM PVC name, VPI/VCI values, Mode, Encapsulation Type and Local WAN IP address.

shows the

Host

Name

,

MAC Address

,

IP Address

and the

Lease Time

.

Wireless Client

This page shows wireless clients that associated to the router. For each client, it shows the

Configuration

DSL Configuration

DSL Line Mode

: The ADSL Router supports multi-mode standard:

Auto

,

G.lite

,

G.dmt

and

ANSI T1.413

. Choose

an appropriate line mode according to the setting of DSLAM in central office and then click

Apply

.

The DSL line mode you specify will be applied to the entire ADSL Router unit. All ATM PVC profiles created will

use the same line mode. Consult your ISP to find out which option applies to your DSL line.

LAN Configuration

For the LAN Configuration, there are two types that you have to know, IP Address and DHCP Server.

IP Address

LAN Configuration allows you to define the public/private IP address over the LAN interface.

Chapter 5: Web Configuration

41

Primary IP Address:

Private IP address is used for the purpose of system management. When it is assigned, PC on

the LAN is able to use the specified address to access this ADSL Router through Ethernet.

By default, the IP address and subnet mask is

192.168.100.100

and

255.255.255.0

respectively.

This will give you an available range of IP addresses from 192.168.100.2 to 192.168.100.254

that can be assigned to PCs on the LAN.

Secondary IP Address:

If you applied for multiple IP address from your ISP, you will have a range of IP address for

the ADSL Router and other network devices on the LAN. You can fill in the IP address

assigned by ISP in the public IP address field.

DHCP Server

This page allows you to enable DHCP server on LAN interface and then your router can assign IP addresses to those

PCs connected to your router.

The ADSL Router implements a built-in DHCP (Dynamic Host Configuration Protocol) server, which dynamically

assigns IP addresses and DNS server to the PCs on the LAN. DHCP function spares you the hassle of manually

assigning a fixed IP address to each PC on the LAN. It is probably you already have a DHCP server on your network

and you do not enable this function. By default the DHCP Server is enabled on private LAN interface

(192.168.100.0).

Choose the

Enabled

radio button and click

Configure

to get advanced settings. Enter the requiring information and

click

Apply

to invoke the configurations that you set. Below is the web page for setting DHCP server.

ADSL Router User Manual

Interface:

Select the interface for the connection of DHCP server. The default one is Primary LAN.

Start IP Address:

Decides the start point of the IP range for this connection.

End IP Address:

Decides the end point of the IP range for this connection.

DHCP lease time

:

Type in the time that a network device can lease a private IP address before the ADSL Router

reassigning the IP address.

Report this host as the default gateway:

Check this box to enable this function.

Default Gateway:

You check the

Report this host as the default gateway

box to use this host as the default

gateway or fill in an IP address as the default gateway.

Report this host as DNS server:

Check this box to enable this function.

Primary DNS server address:

Type in the first DNS server address that you get from your ISP.

Secondary DNS server address:

Type in the second DNS server address that you get from your ISP.

Domain Name Servers

: You can check the

Report this host as the DNS server

box to use this host as the default

DNS. Or you can uncheck the box and manually set up the DNS IP address in the

Primary/Secondary DNS IP address

fields. The DNS server addresses will be passed to the

DHCP clients along with the IP addresses. The DHCP clients use the DNS to map a domain

name to its corresponding IP address and vice versa.

Configuration for Relay Agent

If you want the DHCP server to have the function of relay, please set the Relay Agent for the server. Click the

Relay

Agent

button from the DHCP Server page to get advanced settings. Please enter the IP address for the DHCP Server

and click

Apply

to invoke the configurations.
