This indicates bandwidth(Peak Cell Rate) in cells per second from the local end i.e in the ingress direction of the PVC. For AAL2 PVCs, the PCR to be specified has to be computed based on: a) The no. of channels multiplexed on an AAL2 PVC b) The Codec (Compression Algorithm) used. c) The VAD factor d) Partial fill factor. For a AAL2 bearer PVC, the max value is 60,000 cps on E1 card and 50,000 cps on T1 card, and for a signaling PVC, the max value is 400 cps. This parameter can not be changed when there are calls active on the PVC. For variable bit rate connections the minimum value of PCR is 15.
