  • Method and system for multiplexing/demultiplexing asynchronous transfer mode interprocessor communication (ATM IPC) cell in exchange
    Patent number: 6175567
    Abstract: A system for multiplexing/demultiplexing an ATM IPC cell in an ATM exchange. The system includes an IPC cell multiplexing/demultiplexing circuit connected between an operation and maintenance processor, first to third subscriber control processors and an ATM switch. The IPC cell multiplexing/demultiplexing circuit reads a virtual path identifier (VPI) value of an IPC cell received from the ATM switch to select a processor to transfer the IPC cell to, transfers the received IPC cell to the corresponding processor at a speed of 100 Mbps, and multiplexes the IPC cell received from a specific processor among the operation and maintenance processor and the first to third subscriber control processors.
