Abstract
A SONET path/ATM physical layer transmit/receive processor ASIC for OC-48 makes use of a 32-bit wide interface between a source/destination and the rest of the processor. Adjacent the interface is an ATM cell processor, and between the ATM cell processor and a transmission medium is a SONET payload processor. Selectors are located between the transmission medium and the SONET payload processor, the SONET payload processor and the ATM cell processor, and the ATM cell SONET path/ATM physical layer path, an ATM physical layer path or a fast FIFO buffer path according to the configuration of the selectors determined by user commands from a command logic circuit coupled to each of the interface, ATM cell processor and the SONET payload processor.
