What is acTrunkV5NumberOfCChannels?

This unsigned 1-bit value indicates whether the V5 trunk uses a D-channel (1) for signaling or operates voice-only (0). Administrators set this when provisioning V5 interface lines between access networks and exchanges. Setting to 1 dedicates timeslot 16 to V5 signaling control.
