    摘要： A method and system are provided for concentrating calls for a packet switching system in a hierarchical communication network. A plurality of terminals communicate with an associated plurality of packet concentrators that, in turn, communicate with switching equipment. The system and method comprise initiating a call at a call terminal to be communicated to the packet concentrator and identifying the call terminal by associating a line number communicating the terminal with the concentrator with a first logical channel number for communication from the packet concentrator to the switching equipment. The logic channel number is recorded in association with the first number line at the packet concentrator whereby call communication back to the call terminal can be made on the proper line number by relating the line number with the logic channel line of the call and thereby avoiding the need to switch logic channels between the concentrator and the switching equipment to avoid costly call processing at the concentrator. Further benefits provided by executing of the general call processing at the switching equipment including tariff control.

    摘要： 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.

    摘要： In a packet network which includes a plurality of packet switching stations and in which a packet including in its header portion a VPI (Virtual Path Indentifier) for identifying one of logical paths multipliexed on a transmission line and a VCI (Virtual Connection Identifier) for identifying one of logical connections multiplexed on one logical path is communicated between the switching stations, each switching station preliminarily designates a VCI to be given to a packet directed to that station when a logical connection is to be set up between that station and another station. When receiving an information packet from the other station, the each station makes access to header label conversion tables on the basis of a VCI included in the received packet to read internal routing information necessary for a packet switching operation and a VCI to be given to a packet to be delivered.
