Abstract
A method and system for processing a High level Data Link Control (HDLC) message despite the occurrence of a frame slip event in an Asynchronous Transfer Mode (ATM) receiver avoiding re-transmission of an HDLC message when a frame slip event occurs during reception of an HDLC message. In one embodiment, an ATM receiver receives an ATM cell, where the ATM cell carries one or more T1 payloads. Each T1 payload contains a plurality of timeslots, including an HDLC timeslot. The HDLC timeslot is read for each T1 payload prior to unloading each T1 payload from the ATM cell. The plurality of timeslots within each T1 payload are sent to a switch matrix, where the timeslots are de-multiplexed. The HDLC message is carried in the HDLC timeslot over a plurality of ATM cells and the HDLC message is processed despite the occurrence of a frame slip event.
