PURPOSE: To enable to control one stage constitution spatial switch having greater outgoing and incoming line allcation, by correcting a signal delay time and signal transmission/reception between basic modules.
CONSTITUTION: An m×m one stage constitution spatial switch 10 consists of basic modules A20, 30, B40 and 50. The A20 has time correction sections 24, 26, 27 and a buffer 28 for intra-module signal transmission/reception. An intra- module switch control information and an intra-module connecting information are stoned in a memory section 22. When a switch gate is controlled with the intra-module switch control information and a buffer 25 is controlled depending of this information is effective. The buffer 28 is controlled with the intra-module connection information and the information from incoming line 11 or 12 is transmitted to an outgoing line 13 with the intra-module connecting information.
