This table defines the CAC success or failure statistics. CAC functionality is applied on a per PVC(Permanent virtual circuit) basis for accepting the new calls in a switching model (i.e when CRCX(CreateConnection) message is received from the call agent) and when adding a new binding between a CID(Channel Identifier) and a PVC in the AAL2 trunking application ('addcid' command). In both switching and trunking models, the CAC functionality is applied for upspeeding the connections due to the detection of fax/modem tone on a connection configured with voice compression. The entries in this table are implicitly created and deleted with the creation and deletion of entries in vismChanCnfGrpEntry (defined in CISCO-VISM-CONN-MIB MIB).
