Abstract
A method and apparatus are provided to transport private line traffic over an ATM network. A first plurality of TDM private line traffic links, such as T1 or E1 circuits, are multiplexed to create a first rt-VBR virtual circuit such that the bandwidth of the first rt-VBR virtual circuit is not limited. A second plurality of TDM private line circuits are multiplexed to create a second rt-VBR virtual circuit such that the bandwidth of the second rt-VBR virtual circuit is not limited. This may be done by AAL2 multiplexing with substantially large SCR, PCR and MBS values and the removal of T1 frames that do not contain data (that is, frames that contain only frame delimiters). The first and second rt-VBR virtual circuits are combined for transport over a link in the ATM network. An overload control process may be performed based on the ATM network link utilization.
