3.5.1.5 SNR margin<br />
SNR margin is an index of line connection quality. You can see the actual SNR margin in<br />
STATUS SHDSL.bis. The larger is SNR margin; the better is the line connection quality.<br />
For example, if you set SNR margin in the field to 5, the SHDSL.bis connection will drop and<br />
reconnect when the SNR margin is lower than 5. The device will reduce the line rate and<br />
reconnect for better line connection quality.<br />
The range of SNR margin setting are -10 to 21.<br />
