ABSTRACT:
A multiplexer function maintains a transmission table of all link control frames sent to a physical layer for transmission to a receiver. The transmission table includes a list of frames from various link control entities in the order in which they were multiplexed together to form a stream of frames. At the receiver, when a frame is detected that is in error, the physical layer sends an indication to its associated demultiplexer function, which sets a timer. When the timer expires, the demultiplexer function issues a message, such as a negative acknowledgement message, directly to the sender via the physical layer. The message includes information about the link control frames preceding and following the errant frame. The identified frames may be associated with different link control entities, and are preferably provided in the order in which they were received. The multiplexer function compares the identified frames in the message to the list of frames in the transmission table to identify the errant frame or frames and operates to effect retransmission of the errant frame.
