pwTDMPerfCurrentJtrBfrUnderruns
Module: PW-TDM-MIB
OID (symbolic): PW-TDM-MIB::pwTDMPerfCurrentJtrBfrUnderruns
OID (numeric): 1.3.6.1.2.1.186.1.5.1.3
Node type: OBJECT-TYPE
Type: PerfCurrentCount
Access: read-only
Description: Number of times a packet needed to be played out and the jitter buffer was empty.
What is pwTDMPerfCurrentJtrBfrUnderruns?
Counts the number of times, during the current 15-minute interval, that a packet needed to be played out to the TDM circuit but the jitter buffer was empty. Rising counts suggest the configured pwTDMCfgJtrBfrDepth may be too small for the observed PSN delay variation.
