Module: ADSL2-LINE-MIB

OID (symbolic): ADSL2-LINE-MIB::adsl2LConfProfMaxSnrmDs

OID (numeric): 1.3.6.1.2.1.10.238.1.5.1.2.1.17

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-create

Description: The maximum Noise Margin the ATU-R receiver shall try to sustain. If the Noise Margin is above this level, the ATU-R shall request that the ATU-C reduce the ATU-C transmit power to get a noise margin below this limit (if this functionality is supported). The maximum noise margin ranges from 0 to 310 units of 0.1 dB (physical values are 0 to 31 dB). A value of 0x7FFFFFFF (2147483647) means that there is no maximum.

What is adsl2LConfProfMaxSnrmDs?

This OID specifies the maximum downstream noise margin in 0.1 dB steps (0-310 for 0-31 dB, or 2,147,483,647 to disable the limit) the modem should maintain. You set this ceiling to prevent the modem from maximizing power at the expense of heat, interference, or power consumption. Setting this to 200 (20 dB) means if the noise margin improves beyond 20 dB, the modem will reduce its transmit power to stay below the ceiling.
