摘要： The telephone switching system comprises a plurality of speech path units, a juncture switch unit for interconnecting the speech path units, a central processing unit for controlling the speech path units and the junctor switch unit. Each speech path unit comprises a time switch which shifts a signal which is time-division-multiplexed from time slots of a plurality of incoming highways to other time slots on a plurality of outgoing highways, a digital trunk circuit for processing a register signal received by the time slot and other control signals, and a speech path control equipment which receives and distributes a control signal between the time division switch, the digital trunk circuit and the central processing unit. The junctor switch unit is constructed to change the connections between the speech path units by using a plurality of time slots as one group, whereby the change of connection between respective speech path units by the junctor switch and effects changes in terms of a group units of a plurality of time slots when the number of the speech path units is varied.
