Module: ADSL2-LINE-MIB
OID (symbolic): ADSL2-LINE-MIB::adsl2LConfProfMaxSnrmUs
OID (numeric): 1.3.6.1.2.1.10.238.1.5.1.2.1.18
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-create
Description: The maximum Noise Margin the ATU-C receiver shall try to
sustain. If the Noise Margin is above this level, the ATU-C shall request that the ATU-R reduce the ATU-R 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 adsl2LConfProfMaxSnrmUs?
This parameter holds the maximum upstream noise margin threshold in 0.1 dB units (0-310 for 0-31 dB; special value 2,147,483,647 disables the limit). Engineers configure this to cap upstream power and protect equipment from overly aggressive modulation. A value of 150 (15 dB) caps the modem's upstream signal quality at 15 dB, even if conditions would support higher quality.
