摘要：There is disclosed a control channel interface circuit for interfacing a portprocessor of a distributed multiprocessor communication system to a common timedivision multiplexed bus. The detection, extraction and synchronization of controlmessages passed between a central processor and port processor via a TDM bus arehandled by the interface unit thereby relieving a port processor of this burden. A groupof control time slots within a system frame are dedicated for the transfer of controlmessages between port processors and a central processor. The interface unit alsomonitors the operability of a respective port processor and automatically disables afaulty processor.
