Abstract

PURPOSE:To reduce the load of call given to a time division switch, by connecting arbitrary channels in a PCM line at the front stage of a time division switch fixedly. CONSTITUTION:When a channel (i) of the #M PCM line and a channel (j) of the #N are connected fixedly as an exclusive line, signals from a PCM line are given to a control circuit DTIC via an interface DTI and signals of Mi, Nj are picked up at a fixed path connecting switch SW for mutual switching. On the other hand, the control information relating to the Mi, Nj is re-inserted to a signal bit location corresponding to the opposing channel at a signal pickup/ insertion circuit DI. The SW is provided with information representing exclusive line in advance.
