Contact your ISP to make sure that these parameters are correct.

Modulation:

There are 7 modes “G.Dmt”, “G.lite”, “T1.413”, “ADSL2”, “AnnexL”, ”ADSL2+”, “AnnexM”

that user can select for this connection.

Phone line pair

Apply to confirm the settings.

Click

to future configure DSL.

Select the Test Mode, or leave it as default.

Tone Selection: This should be left as default or be configured by an advanced user.

The frequency band of ADSL is split up into 256 separate tones, each spaced 4.3125 kHz apart.

With each tone carrying separate data, the technique operates as if 256 separate modems were

running in parallel. The tone range is from 0 to 31 for upstream and from 32 to 255 for downstream

。

SNR

Signal-to-noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering

that compares the level of a desired signal to the level of background noise. It is defined as the ratio of

signal power to the noise power.

SNR

: Change the value to adjust the DSL link rate, more suitable for an advanced user.

System

Internet Time

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

to get the most current time from an NTP server.

NTP is a protocol for synchronization of computers. It can enable computers synchronize to the NTP

server or clock source with a high accuracy.

Choose the NTP time server from the drop-down menu, if you prefer to specify an NTP server other

than those in the drop-down list, simply enter its IP address in their appropriate blanks provided as

shown above. Your ISP may also provide an SNTP server for you to use.

Choose your local time zone from the drop-down menu. After a successful connection to the Internet,

the router will retrieve the correct local time from the NTP server you have specified. If you prefer to

specify an NTP server other than those in the drop-down list, simply enter its IP address in their

appropriate blanks provided as shown above. Your ISP may also provide an NTP server for you to

use.
