ABSTRACT:
An ATM switch system performs a DMA (direct memory access) transfer of a command and status data between a call processor and a processor of a communications control device via a peripheral interface. An inter-processor DMA transfer controller of the communications control device controls a DMA transfer between its memory and the main memory of a call processor for expediting communications between the two processors.
