SHDSL SNR margin:

The margin range is from 0 to 10.

 

SNR margin is an index of line connection. You can see the

 

actual SNR margin in STATUS SHDSL. The larger the SNR

 

margin, the better the line connection.

 

If you set the SNR margin in the field to 2, the SHDSL

 

connection will drop and reconnect when the SNR margin

 

is lower than 2. I.e., the device will reduce the line rate and

 

reconnect for better line connection.

The screen will display the parameters that will be written to EPROM. Check the parameters before writing to

EPROM.

Press Restart to restart the router with the new parameters or press Continue to setup other parameters.
