pbcCmtsIfUpstreamMER
Module: PBC-CMTS-MIB
OID (symbolic): PBC-CMTS-MIB::pbcCmtsIfUpstreamMER
OID (numeric): 1.3.6.1.4.1.5987.2.2.1.3.2.1.5
Node type: OBJECT-TYPE
Type: TenthdB
Access: read-only
Description: Upstream channel's modulation error ratio expressed in dB.
What is pbcCmtsIfUpstreamMER?
This read-only value reports the upstream channel's modulation error ratio (MER) in tenths of a dB, a measure of signal quality — higher values mean a cleaner signal. An admin uses a dropping MER on a channel as an early warning of plant noise or ingress before it causes modem flaps.
