Command Usage
This command sets the noise margin that transceivers must achieve
with a Bit Error Rate (BER) of 10
-7 or better to successfully complete
initialization. It indicates the maximum amount by which the reference
crosstalk noise level can be increased during a BER test without
causing the modem to fail the BER requirement.
Example
The following sets a targeted SNR of 15 dB on Port 1.
