4.6.4.2 <NM> & <LINKNM> Command
The <NM> command displays the ITU-T G.991.2 Noise Margin. It means the maximum possible
increase in the Noise Margin for which the BER is expected to be not less than 10
-7
[dB].
CO_FMM>NM
Channel: DSL1 DSL2 DSL3 DSL4
SHDSL NM: 10.5 11.5 10.5 10.0 dB
The number of columns is equal to the number of SHDSL channels of the device.
The <LINKNM> command displays the noise margin of a complete link (CO, RR and CP).
A normal quality of a SHDSL data transmission is possible for NM ≥ 6 dB.
4.6.4.3 <STATUS> Command
The <STATUS> command displays the actual status of the SHDSL transceiver.
