SNR

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.

Click Apply to apply your settings.
