Information About

Virtual Channel Identifier




ATM switches use the VPI/VCI fields to identify the virtual channel link {VCL} of the next network that a cell needs to transit on its way to its final destination. The function of the VCI is similar to that of the data-link connection identifier DLCI in Frame Relay and the Logical Channel Number & Logical Channel Group Number in X.25 .
