Description: This object keeps track of AAL2 CPS packets dropped in the egress direction due to invalid length field.
What is vismChanAal2CpsInvLenPkts?
This Counter32 tracks AAL2 CPS packets dropped in the egress direction due to an invalid length field. An invalid length field means the packet's declared size doesn't match its actual content, which points to a framing or corruption issue in the AAL2 stream for that channel. An engineer isolating dropped voice packets on a specific channel would check this counter to see whether length-field corruption, rather than CID or UUI mismatches, is the cause.
