TELECOMMUNICATION SWITCHING SYSTEM

摘要

A telecommunication switching system in which a required number of switching arrays or matrixes are divided together and the switching arrays or matrixes are divided into a group having in a predetermined ratio outlets of non-multiple connection and outlets of multiple connection and a group having outlets of multiple connection. whereby to obtain a desired concentration ratio without using new exclusive switching arrays or matrixes or rendering some inlets of the switching arrays or matrixes no use. In the selection or hunting of outlets of the switching arrays or matrixes, the selection or hunting starts with the outlets of non-multiple connection so long as an idle outlet exists, and thereby improve the traffic characteristics of switching system.
