adsl2LConfProfMinSnrmDs

Module: ADSL2-LINE-MIB

OID (symbolic): ADSL2-LINE-MIB::adsl2LConfProfMinSnrmDs

OID (numeric): 1.3.6.1.2.1.10.238.1.5.1.2.1.19

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-create

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

What is adsl2LConfProfMinSnrmDs?

This OID stores the minimum tolerable downstream noise margin in 0.1 dB units (range 0-310, representing 0-31 dB) before the link is considered failing. When conditions drop below this floor, the modem signals a loss-of-margin defect and initiates line recovery. For instance, setting this to 30 (3 dB) means if downstream noise margin falls below 3 dB, the modem will trigger a reconnection attempt.
