SIGNAL BUFFING SYSTEM

摘要

PURPOSE:To avoid the loss of signals in case of fault by using a memory which can be referred to from both a signal ink control processor and a signal network control processor and storing the buffers for transmission/reception signals and retransmission signals in said memory. CONSTITUTION:Signal link control processors SLC1-SLCn and a signal network control processor SNC can refer to double port memories M1-Mn. Then the buffers for transmission/reception signals and retransmission signals are stored in those double port memories. Thus the signals sent from the processor SNC and stored in a buffer can be collected even in a faulty mode of processors SlC1-SLCn.
