Type: Unsigned32

Access: read-create

Description: The minimum Noise Margin the ATU-C receiver shall tolerate. If the noise margin falls below this level, the ATU-C shall request that the ATU-R increase the ATU-R transmit power. If an increase of ATU-R transmit power is not possible, a loss-of-margin (LOM) defect occurs, the ATU-C 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.

What is adsl2LConfProfMinSnrmUs?

This parameter defines the minimum acceptable upstream noise margin in 0.1 dB increments (0-310 units, equivalent to 0-31 dB) before line failure. Network engineers set this to prevent the connection from limping along on a degraded upstream path. A value of 25 (2.5 dB) causes the modem to fail and restart if upstream signal quality falls below 2.5 dB for a sustained period.
