This read-only Integer32, expressed in Kbps, reports the aggregate rate of all voice channels configured on this OC-3 port, counting a channel as configured whenever a ComPort with a voice channel is assigned to a VLAN riding this port, regardless of whether that ComPort has actually acquired service, and the rate applies identically to both upstream and downstream. It gives an administrator the total provisioned voice-service capacity demand on this optical trunk. For example, an operator planning to add more voice subscribers behind this OC-3 uplink would check this configured aggregate against the trunk's overall bandwidth budget.
