ATM communication system and method for utopia interface

摘要

The invention is a kind of ATM communication interface, named Pseudo-UTOPIA interface. By this interface, an ATM device can communicate with standard UTOPIA PHY devices through a high-speed transmission medium with a most efficient way (minimum transmission delay) and without the need of any extra devices. The Pseudo-UTOPIA interface can be used in both the UTOPIA Level 2 and Level 1 mode. The cost can thus be significantly reduced.
