Snr Margin; Line Probe - netsys G.SHDSL.bis 3010E User Manual

3.5.1.5 SNR margin

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

For adaptive mode, you can setup the Line Probe to Enabled. The EFM modem will adapt the data rate
according to the line status. Otherwise, setup to Disabled.
The screen will prompt the parameters that will be written in NVRAM. Check the parameters before writing in
NVRAM.
Press Restart to restart the EFM modem working with new parameters or press continue to setup another
parameter.
