ABSTRACT:
A scheme for using a virtual UNI (user network interface) to allow standards-based signaling protocols (e.g., Q.2931) to be used to manage the addition and deletion of AAL2 channel identifiers (CIDS) associated with sub-multiplexed AAL2 common part sub-layer cells is described herein. An ATM node is configured to dynamically establish ATM adaptation layer 2 (AAL2) channel identifiers (CIDS) on a call-by-call basis using standards-based call control signaling protocols mapping CIDs to a virtual path/virtual channel (VP/VC) within an ATM standard call control protocol.
