Module: Fore-DS3-MIB
OID (symbolic): Fore-DS3-MIB::ds3PlcpYellows
OID (numeric): 1.3.6.1.4.1.326.2.2.1.1.3.2.2.1.8
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of seconds in which Yellow alarm errors were detected by the PLCP (Physical Layer Convergence Protocol) receiver. Yellow alarm is asserted when 10 consecutive yellow signal bits are set to logical 1. Yellow signals are used to alert upstream terminals of a downstream failure in order to initiate trunk conditioning on the failure circuit.
What is ds3PlcpYellows?
A read-only counter of seconds in which the PLCP receiver detected a Yellow alarm, asserted after 10 consecutive yellow signal bits and used to alert the upstream terminal of a downstream failure so it can begin trunk conditioning. Seeing PLCP yellow seconds tells the admin the fault is downstream of this device rather than local.
