Method and apparatus for dynamic bandwidth allocation for voice and data multiplexing over AAL-2 connections

A method comprising:

• receiving a traffic-type parameter and one or more predefined parameters for an ATM Adaptation Layer type 2 (AAL-2) connection:
• segmenting in run-time a frame of user information received over said AAL-2 connection into a Common Part Sublayer (CPS) service data unit whose length is determined according to said traffic-type parameter and according to one or more of said predefined parameters;
• and
• calculating an available bandwidth for a current CPS protocol data unit (CPS-PDU),
• wherein receiving said predefined parameters comprises receiving a maximum data size threshold parameter;
• and
• wherein segmenting said frame comprises:
• comparing said available bandwidth to said maximum data size threshold parameter;
• and
• extracting said CPS service data unit with a length equivalent to said maximum data size threshold parameter if said available bandwidth has a value greater than said maximum data size threshold parameter.
