hwAdslnniLineStatusSnrMarginDs
Module: HUAWEI-ADSLNNI-MIB
OID (symbolic): HUAWEI-ADSLNNI-MIB::hwAdslnniLineStatusSnrMarginDs
OID (numeric): 1.3.6.1.4.1.2011.6.143.1.1.3.1.12
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Downstream SNR Margin is the maximum increase in dB of the noise power received at the ATU-R, 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 hwAdslnniLineStatusSnrMarginDs?
This read-only Integer32, in units of 0.1 dB (physical range roughly -64 to 63 dB), is the downstream SNR margin -- how much extra noise the ATU-R could tolerate and still hit the required bit-error rate. A margin dropping toward zero on a line that used to run comfortably above it is an early warning of upcoming CRC errors or a dropped sync.
