VCC

virtual channel connection

A VCC is the series of cross-connections used to traverse an ATM network end-to-end. This ATM concept describes a type of path through an ATM network, defined by its VPI and VCI values.

VCCs represent a specific instance of a PVC, SPVC, or SVC. They are formed as a concatenation of one-hop connections that are cross-connected on workgroup switches. VCCs are unidirectional. They do not use bandwidth if there is no data to transmit.
