Abstract
The invention is a method for transporting a voice band signal with channel-associated signaling over an ATM system. The method comprises converting the signal into ATM cells so that the sequence numbers in the cells correspond to the location of the signaling in the cells. After transmission over the ATM system, the ATM cells are converted back into the signal using the sequence numbers in the cells to locate the signaling in the cells. The convergence sublayer indication bit of a segmentation and reassembly protocol data unit header of an ATM adaption layer 1 ATM cell can be used as a portion of the sequence numbers so that the sequence numbers can use a repeating 12-count sequence.
