Authentication Protocol:

Default is Chap(Auto). Your ISP will advise you whether to use Chap or Pap.

Connection:

~

Always on:

If you want the router to establish a PPPoE session when starting up and to

automatically re-establish the PPPoE session when disconnected by the ISP.

~

Connect on Demand:

If you want to establish a PPPoE session only when there is a packet

requesting access to the Internet (i.e. when a program on your computer attempts to access the

Internet).

Idle Timeout:

Auto-disconnect the broadband firewall gateway when there is no activity on the line for a

predetermined period of time.

~

Detail:

You can define the destination port and packet type (TCP/UDP) without checking by

timer. It allows you to set which outgoing traffic will not trigger and reset the idle timer.

RIP:

RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.

MTU:

Maximum Transmission Unit. The size of the largest datagram (excluding media-specific headers)

that IP will attempt to send through the interface.

Advanced Options (PPPoE)

LLC Header:

Selects encapsulation mode, true for using LLC or false for using VC-Mux.

Create Route:

This setting specifies whether a route is added to the system after IPCP (Internet Protocol

Control Protocol) negotiation is completed. If set to

enabled

, a route will be created which directs packets

to the remote end of the PPP link.

Specific Route:

Specifies whether the route created when a PPP link comes up is a specific or default

route. If set to

enabled

, the route created will only apply to packets for the subnet at the remote end of the

PPP link. The address of this subnet is obtained during IPCP negotiation.

Subnet Mask:

sets the subnet mask used for the local IP interface connected to the PPP transport. If the

value

0.0.0.0

is supplied, the netmask will be calculated from the class of the IP address obtained during

IPCP negotiation.

Route Mask:

Sets the subnet mask used by the route that is created when a PPP link comes up. If it is

set to

0.0.0.0

, the subnet mask is determined by the IP address of the remote end of the link. The class of

the IP address is obtained during IPCP (Internet Protocol Control Protocol) negotiation.

MRU:

Maximum Receive Unit. This is negotiated during the LCP protocol stage.

Discover Primary / Secondary DNS:

This setting enables/disables whether the primary/secondary DNS

server address is requested from a remote PPP peer using IPCP. The default setting for this command is

enabled

.

Give DNS to Relay:

Controls whether the PPP Internet Protocol Control Protocol (IPCP) can request the

DNS server IP address for a remote PPP peer. Once IPCP has discovered the DNS server IP address, it

automatically gives the address to the local DNS relay so that a connection can be established.

Give DNS to Client:

Controls whether the PPP Internet Protocol Control Protocol (IPCP) can request a

DNS server IP address for a remote PPP peer. Once IPCP has discovered the DNS server IP address, it

automatically gives the address to the local DNS client so that a connection can be established.

Give DNS to DHCP Server:

Similar to the above, but gives the DNS server address to the DHCP server.

Discover Primary NBNS / Discover Secondary NBNS:

This setting enables/disables whether the

primary/secondary NBNS server address is requested from a remote PPP peer using IPCP. The default

setting for this command is disabled.

Discover Subnet Mask:

Specifies if the subnet mask given by IPCP negotiation process is to be used.

Give Subnet Mask To DHCP Server:

Enable to change your DHCP Server settings by using the given

information in IPCP negotiation process.

DNS

A Domain Name System (DNS) contains a mapping table for domain name and IP addresses. On the

Internet, every host has a unique and user-friendly name (domain name) such as www.helloworld.com

and an IP address. An IP address is a 32-bit number in the form of

xxx.xxx.xxx.xxx

, for example

192.168.1.254. You can think of an IP address as a telephone number for devices on the Internet, and the

DNS will allow you to find the telephone number for any particular domain name. As an IP Address is hard

to remember, the DNS converts the friendly name into its equivalent IP Address.

You can obtain a Domain Name System (DNS) IP address automatically if your ISP has provided it when

you logon, check the

Enable

box. Usually when you choose PPPoE or PPPoA as your WAN - ISP

protocol, the ISP will provide the DNS IP address automatically. You may leave the configuration field

blank.

Alternatively, your ISP may provide you with an IP address of their DNS. If this is the case, you must enter

the DNS IP address manually.

If you choose one of the other three protocols

─

RFC1483 Routed/Bridged and IPoA check with your ISP,

it may provide you with an IP address for their DNS server. You must enter the DNS IP address if you set

the DNS of your PC to the LAN IP address of this router.

ADSL

Connect Mode:

This mode will automatically detect your ADSL line code, ADSL2+, ADSL2, G.dmt,

G.lite, T1.413, AnnexM2 and AnnexM2+. But in some area, multimode cannot detect the ADSL line code

well. If it is the case, please adjust the ADSL line code to G.dmt or T1.413 first. If it still fails, please try the

other values such as ALCTL, ADI, etc.

If you still having trouble with the line, please check with your ISP

for line connect information.

Note:

If you have subscribed ADSL1 T1.413 mode line, you may go to the Advanced Options for more connection

module combinations.

Activate Line:

Aborting (false) your ADSL line and making it active (true) again for taking effect with

setting of

Connect Mode

.

Coding Gain:

It reduces router’s transmit power which will effect to router’s downstream performance.

Higher the gain will increase the downstream rate but it sometimes causes unstable ADSL line. The

configurable ADSL coding gain is from 0 dB to 7dB, or automatic.

Tx Attenuation:

It is the ADSL transmission power that the modem is using. The lower the power the

better performance in router’s upstream.

Configurable value is between 0~12.

DSP Firmware Version:

Current ADSL line code firmware version.

Connected:

Display current ADSL line sync status.

Operational Mode:

Display current ADSL mode standard (Operational Mode) your Router is using when

ADSL line has sync.

Annex Type:

ADSL Annex A, which works over a standard telephone line. Annex B, which works over an

ISDN line.

Upstream:

Display current upstream rate of your ADSL line.

Downstream:

Display current downstream rate of your ADSL line.

Advanced Options

ADSL Parameters help to interpret your ADSL line statistics.

SNR Margin:

It is known as Signal to Noise Ration Margin. It is the relative of DSL strength to Noise ratio.

This margin is measured in decibels (dB).

Higher the dB figures better the DSL strength and better

chance to get faster speed. THE HIGHER THE BETTER

Line Attenuation:

it measures the signal loss in decibel (dB) between the CO DSLAM. Lower the

attenuation dB figures better the DSL strength/speed.

THE LOWER THE BETTER.

CRC Errors:

It is known as Cyclic Redundancy Check Error.

Its checksum is to detect the transmission

error.

Latency:

It includes two channels, Fast and Interleaved. It displays the channel adapted by your ISP.

Capability:

There are more combinational ADSL modulation modes to be selected.

~

GDMT:

ADSL connection will be limited to ADSL1 (G.DMT / G.Lite) only.

~

BIS+:

ADSL connection will be limited to ADSL2+ only. (If you are ADSL1 subscriber DO NOT

select this option).

~

System

Here are the items within the

System

section:

Time Zone, Remote Access, Firmware Upgrade,

Backup/Restore, Restart

and

User Management.

Time Zone

The router does not have a real time clock on board; instead, it uses the Simple Network Time Protocol

(SNTP) to get the current time from an SNTP server outside your network. Choose your local time zone,

click

Enable

and click the

Apply

button. After a successful connection to the Internet, the router will

retrieve the correct local time from the SNTP server you have specified. If you prefer to specify an SNTP

server other than those in the list, simply enter its IP address as shown above. Your ISP may provide an

SNTP server for you to use.

Daylight Saving

is also known as

Summer Time Period.

Many places in the world

adapt it during

summer time to move one hour of daylight from morning to the evening in local standard time.

Check

Automatic

box to auto set your local time.

Resync Period

(in minutes) is the periodic interval the router will wait before it re-synchronizes the

router’s time with that of the specified SNTP server. In order to avoid unnecessarily increasing the load

on your specified SNTP server you should keep the poll interval as high as possible – at the absolute

minimum every few hours or even days.
