Dynamic adjustment of AAL2 TIMER_CU in voice and data multiplexing over AAL2 connections

A method for determining at least one parameter for a particular AAL2 channel identifier (AAL2-CID), according to which the behavior of the transmission of the user information stream is determined per application. Preferably, the present invention enables the QOS (quality of service) for the user application to be determined by setting a plurality of such parameters for a specific AAL2 CID. The present invention preferably encompasses the ability to determine any parameter that is usually set for the ATM channel to instead be set for the CID separately. Example of such parameters include, but are not limited to, traffic type, priority, any type of QOS parameter, timing parameters, and so forth.
