Abstract
In an Asynchronous Transfer Mode (ATM) communications network which operates over a shared media a method of addressing and access control between a central transceiver and multiple transceivers in a residence is required. A device identifier is placed in the in the Generic Flow Control (GFC) field of the ATM cells to indicate that cells are designated for a particular transceiver or transceivers in the residence. In the reverse direction, transceivers in the residence use the GFC field to indicate that they are attempting to sign onto the network. The GFC bits are returned to zero prior to passing the ATM cells to the ATM processing layer.
