Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-create

Description: The Downstream Down-Shift Noise Margin value, to be used when adsl2LConfProfRaModeDs is set to dynamicRa. If the downstream noise margin is below this value and stays below that for more than the time specified by the adsl2LConfProfRaDsTimeDs, the ATU-R shall attempt to decrease the downstream net data rate. The Downstream Down-Shift Noise Margin ranges from 0 to 310 units of 0.1 dB (physical values are 0 to 31 dB).

What is adsl2LConfProfRaDsNrmsDs?

This OID holds the noise margin threshold in units of 0.1 dB (range 0-310, representing 0-31 dB) below which the modem should reduce downstream speed. System administrators set this to protect against unstable links running at excessive speeds when conditions are marginal. For instance, a value of 50 (representing 5 dB) tells the modem to prepare for a speed reduction if the noise margin drops below 5 dB.
