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 the line connection quality.
For example, if you set SNR margin in the field to 5, the SHDSL.bis connection will drop and
reconnect when the SNR margin is lower than 5. The device will reduce the line rate and
reconnect for better line connection quality.
The range of SNR margin setting are -10 to 21.
3.5.1.6 Line Probe
For adaptive mode, you can setup the Line Probe to Enable. The EFM modem will adapt the
data rate according to the line status. If you want to set a fixed rate, set to Disable.
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 other parameter.
