| Description | The minimum Noise Margin the xTU-R receiver shall tolerate.
If the noise margin falls below this level, the xTU-R shall
request that the xTU-C increase the xTU-C transmit power.
If an increase to xTU-C transmit power is not possible, a loss-
of-margin (LOM) defect occurs, the xTU-R shall fail and attempt
to reinitialize and the NMS shall be notified. The minimum noise
margin ranges from 0 to 310 units of 0.1 dB (physical values are
0 to 31 dB). A value of 0 means that there is no minimum. |
