Abstract

A method and apparatus are disclosed for communicating between devices in a network. The invention allows the combination of TDM and ATM signals in a frame for communication over a communications link. In accordance with the method of the invention, a frame is formed in a first device. The frame comprises a predetermined number of bytes. Some of the bytes carry time division multiplexed time slot data while other bytes carry asynchronous transfer mode cell data. The frame is sent to a second device over a communications link.
