adsl2LineStatusSnrMarginUs
Module: ADSL2-LINE-MIB
OID (symbolic): ADSL2-LINE-MIB::adsl2LineStatusSnrMarginUs
OID (numeric): 1.3.6.1.2.1.10.238.1.1.1.1.19
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Upstream SNR Margin is the maximum increase in dB of the noise power received at the ATU-C, such that the BER requirements are met for all downstream bearer channels. It ranges from -640 to 630 units of 0.1 dB (physical values are -64 to 63 dB). A special value of 0x7FFFFFFF (2147483647) indicates the SNR Margin is out of range to be represented. A special value of 0x7FFFFFFE (2147483646) indicates the SNR Margin measurement is currently unavailable.
What is adsl2LineStatusSnrMarginUs?
This OID stores the upstream signal-to-noise ratio margin, measured in 0.1 dB units (ranging from -64 to 63 dB), indicating how much additional noise the line can tolerate while maintaining data quality. Network engineers monitor this to detect line degradation or impending connection dropout. A value of 200 means the link has a 20 dB safety margin before errors occur; values below 50 (5 dB) typically indicate a failing or marginal line.
