ABSTRACT:
A packet switching system which includes a device for setting, between a tandem unit and a destination local unit, the same logic channel as that between an originating local unit operative for information transfer and the tandem unit in respect of a call destined for a local unit other than the originating local unit and a device, operable in the originating-side local unit for information transfer, for inserting output port information of a self-routing switch inside the tandem unit into a packet destined for the local unit other than this local unit; in the tandem unit, setting of logic channel conversion information is not required to be done and even when any control signal packet from the originating local unit arrives at the tandem unit, the packet is transferred to the destination local unit without undergoing termination of packet and concomitant call processing control.
