Module: ADSL-MIB
OID (symbolic): ADSL-MIB::usrAdslMeanSqError
OID (numeric): 1.3.6.1.4.1.429.4.26.8

Description: Received signal to noise ratio.
What is usrAdslMeanSqError?
This OID reports the signal-to-noise ratio (SNR) as a measure of received signal quality on the ADSL line. Engineers monitor SNR to predict line stability and potential dropout events, as low SNR often precedes connection failures. A value of 10 dB indicates marginal line quality, while 20 dB or higher is considered good for stable ADSL service.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.429.4.26.8 snmpwalk -v2c -c public <target> ADSL-MIB::usrAdslMeanSqError
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.429.4.26.8.1 snmpget -v2c -c public <target> ADSL-MIB::usrAdslMeanSqError.1
