Abstract
A system for managing data communication between physical layer devices and ATM layer devices in a cell based ATM network is disclosed. A plurality of low speed physical layer devices a high speed physical layer device are connected to a bus. A bus interface device is coupled to the bus, the low speed physical layer devices, and the high speed physical layer device. The bus interface device is operable to provide equal opportunities to access the bus to any connected physical layer device. An arbiter is coupled to the low speed physical layer devices, the high speed physical layer devices, and the bus interface device. The arbiter is operable to provide the high speed physical layer device with disproportionately frequent access to the bus.
