CHANNEL SWITCH CONTROL SYSTEM

摘要

PURPOSE:To make the initial set easy and to avoid induced noise, by providing a memory for storage circuit storing control information to all cross points of a channel line matrix and writing control information of cross point in the matrix in this circuit. CONSTITUTION:Control information of all cross points 311-3lm in a channel matrix 5 connected among incoming lines 11-1l and outgoing lines 21-2m, is stored in storage memories 51-5l as a storage circuit. All horizontal cross point are written in one address in a memory 6 for switch control and a gate signal written in the memories 51-5l is transmitted from a signal forming circuit 7 in synchronizing with the transmission information of the memory 6. All the addresses are transmitted from the memory 6 within a prescribed period to the memories 5a-5l as control information repetitively, a gate signal synchronized with the circuit 7 is transmitted, the control of the cross points 311- 3lm of the matrix 5 is done with the memories 51-5l to facilitate initial setting.
