摘要：
An asynchronous transfer mode (ATM) layer (10) is coupled to one or more physical layers (PHY layer) (12) via a plurality of conductors (14 and 16). The conductors (14 and 16) allow bi-directional communication of ATM data cells between the layers (10 and 12) using the UTOPIA protocol. In addition, the ATM layer (10) and the PHY layer (12) can communicate one or more status bytes and one or more physical identification (PHY ID) bytes to each other prior to the communication of an ATM data cell. This addition of the communication of one or more status bytes and one or more physical identification (PHY ID) bytes is fully compatible with the currently accepted UTOPIA standard and therefore adds new ATM functionality without compromising the widely-accepted UTOPIA standard for ATM.
