Module: CPIWF-MIB

OID (symbolic): CPIWF-MIB::cpIwfIsdnBriPortB1DroppedOctets

OID (numeric): 1.3.6.1.4.1.353.5.10.1.1.8.1.3

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: Total number of PCM payload octets dropped due to buffer overflow on this port/channel. Octets that are dropped because they arrived late, and which have already been substituted by filler PCM octets, shall not be counted.

What is cpIwfIsdnBriPortB1DroppedOctets?

This read-only Counter32 counts total PCM payload octets dropped due to buffer overflow on the B1 channel, excluding octets already substituted by filler because they arrived late. It flags the opposite jitter-buffer failure mode from the filler-octet counter, specific to the B1 channel. A rising count here on B1 while B2 stays clean tells the admin the overflow problem is isolated to that one bearer channel.
