4.6.4.2 <NM> command
The
<NM>
command displays the ITU-T G.991.2 Noise Margin performance parameters.
(The maximum possible increase in the noise margin at which the BER is expected to be less
that 10
-7
.)
The action of the <NM> command terminates by entering any other command or by pressing
“enter”.
