This counter tallies SVC VCCs established at this signalling entity for incoming connections. Because this counts successfully completed setups rather than attempts, pairing it with ciscoatmSigDetectSetupAttempts gives the real incoming call success rate for this signaling entity, a number worth tracking over time to catch a gradual degradation in call success even if no individual failure-cause counter is spiking. This counter holding steady while ciscoatmSigDetectSetupAttempts slowly rises over weeks would reveal a creeping decline in call success rate that no single failure-cause counter alone would clearly show.
