The purpose of the present invention is to provide a switchboard control system that enables efficient operation of a switching network by setting a connection route that is different from that of a general call only, and then changing the connection route to the same as that of a general call after the call begins. That is.

That is, the present invention provides a switching network consisting of a switching center A having a plurality of switchboards providing switchboard services and a plurality of switching centers B including a plurality of switching boards, in which the switching center BVC, the switching center A call is received on the person trunk between the personified interface call trunk, the incoming trunk and outgoing trunk of exchange B, and the board trunk connected to the above interface call trunk via the main switch, and exchange A. A communication control device that communicates call information of a switchboard service request call, and a processing device that controls the call control device and switching center B, and
an interface call trunk connected to the interface call trunk of , a plurality of switchboards connected to the interface call trunk via a main switch to provide switchboard services, and a communication control unit connected to the call control device of the above-mentioned exchange B. a device, the communication control device, and a processing device that controls exchange waste input, and provides a switchboard service for a switching center B that does not have a switchboard at the switchboard that is under the control of the switching center A. This is the one I configured to do this.

Hereinafter, the present invention will be explained based on the embodiments shown in the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. The switchboard control system of the present invention shown in the figure is applied to a switchboard B that does not have a switchboard and a switchboard A that has a switchboard that provides switchboard services.

Exchange B includes a main switch 14 and incoming trunks 11 . An outgoing trunk 12, an interface call trunk 15, a board trunk 13 having three input/output terminals 13ae, 13be, and 13c and housed in the main switch 14, a communication control device 17, an exchange B, and a communication control device 17. and a processing device 16 that controls the processing.

On the other hand, the replacement waste container is connected to the main switch 24, the incoming trunk 21 and the outgoing trunk 2 accommodated in the main switch 24.
2 and the interface call trunk 15 of the exchange B
an 8-talk interface trunk 25 connected to the main switch 24, a switching board 28 that is housed in the main switch 24 and provides various services to the operator, and three input/output terminals 23m and 23b.

23c and is accommodated in the main switch 24, a communication control device 27 connected to the communication control device 17 of the exchange B, and the exchange A and communication f/li control device 27. and a processing device 26.

In such a configuration, when a switchboard service request call from within the switching center B area arrives at the incoming trunk 11, the communication path of the incoming call is from the incoming trunk 11 to the main switch 14.
Board trunk 130 input/output terminal 13b, board trunk 13t, its input/output terminal 13C, main switch 14.
Interface Call Trunk 15. Interface call trunk 25. Main switch 24. It is connected through the route of the switchboard 28. The call information of the above-mentioned incoming call necessary for this connection is sent to the processing device 16. Communication control device 179 Communication control device 2
7. The processing unit 26 notifies the exchange AK.

Upon completion of the connection of the communication path, the called subscriber is called by the operator of the switchboard 28.

The call path at this time is switchboard 28. Main switch 2
4. Interface call trunk 25. Interface Call Trunk 15. Main switch 14, input/output terminal 13C of board trunk 13, board trunk 13. Its input/output terminal 13a, main switch 14. Exit trunk 1
2 routes to the called party. The connection information at this time is communicated between the communication control devices 17 and 27 as described above.

When the call path is completed, the call becomes a champion call under the control of the board trunk 13#i and the processing device 160, and the switchboard 28 is disconnected from the dead call after the operator confirms the call. The separation information is communicated between the communication control devices 17 and 27 in the same manner as described above. In this state, the call is incoming trunk 11. The main switch 14° is connected to the called subscriber via the outgoing trunk 12 route, and exchange service calls within the exchange B area are communicated with the called party through the same trunking as general calls, without bypassing the exchange AK. The path is set.

In the above embodiment, there is one exchange B and 1. Although an example has been given of an exchange AK having one exchange, this is merely an example for explanation, and the present invention is applicable to a plurality of exchanges BK and an exchange AK having a plurality of exchanges. It can also be applied.

As explained above, the present invention installs a switching center having a switchboard that provides switchboard services in common to a plurality of predetermined regions, and If a station is configured to accept calls requesting switchboard service and connect the calls to a switchboard having the above-mentioned switchboard via a board trunk, then from K, it is possible to install the switchboards in a concentrated manner in a certain area, and the division loss is reduced. In addition, switchboard service and service request calls from the above-determined areas are connected via a different connection route from general calls only at the time of reception, and after the call begins, the connection route is the same as that for general calls.
