COMMUNICATION BUS FOR D-CHANNEL INFORMATION OPERATION

摘要

This system provides an interprocessor communication bus to perform a multi-bus structure and a function of bus control section. In a subscriber mode of ISDN being comprised one master node and multi-slave nodes, and in interprocessor communication means sending signal and data clock for information transmission, the bus includes a clock loop line (a) which provides the control clock to the slave nodes, the 1st data loop line (b) which provides data from the master node to the slave nodes, and the 2nd data loop line (c) which provides data from the slave nodes to the master node.
