Command Usage
This command sets the minimum noise margin the receiver can
tolerate. If the noise margin falls below this level, the receiver will ask
the sender to increase its transmit power. If it is not possible to
increase the transmit power, a loss-of-margin defect occurs, the link
will fail and the receiver will attempt to re-initialize.
