cpIwfIsdnBriPortB2DroppedOctets

Module: CPIWF-MIB

OID (symbolic): CPIWF-MIB::cpIwfIsdnBriPortB2DroppedOctets

OID (numeric): 1.3.6.1.4.1.353.5.10.1.1.8.1.6

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 cpIwfIsdnBriPortB2DroppedOctets?

This read-only Counter32 counts total PCM payload octets dropped due to buffer overflow on the B2 channel, excluding octets already substituted by filler because they arrived late. It flags overflow-related loss specific to the B2 bearer channel, distinct from underflow issues tracked by the B2 filler-octet counter. A rising value here while B1's equivalent counter stays flat isolates a buffer-overflow problem to the B2 channel alone.
