れる。To achieve this objective, the connection scheme according to the invention:
When a calling party calls a called terminal in another exchange network, it first sends out the special trunk connection number of its own exchange, and then sends out the calling number of the called terminal. When the exchange is activated and a special trunk connection is made, the special trunk receives the calling number of the called terminal, and transfers the exchange number located at the beginning of the called number of the called terminal to the local adjacent to the exchange. Translated into the exchange number within the exchange network. The special trunk adds the connection number of the trunk connecting to another exchange (hereinafter referred to as the other exchange trunk) to the translation number,
It is sent to the own exchange and connected to other exchange trunks of the exchange via the own exchange network. When the above connection is completed, the calling number of the called terminal is sent as an audio frequency signal from the special trunk to the other switched trunk. The other exchange trunk converts the calling number of the called terminal received as an audio frequency signal into information that drives the exchange that accommodates the called terminal, such as a dial pulse, and sends it to the exchange to make the call. A terminal is connected to a called terminal in another switched network.

以上述べたように本発明によれば、異なる電話交換網間
の接続が、自交換網を経由してモきるので、経費的にま
たは品質的に有利な接続が可能となる。The present invention will be explained below with reference to the illustrated embodiments. FIG. 1 shows a conventional connection system, and FIG. 2 shows an embodiment of the present invention. In the first and second time,
People are one exchange network, B is a different exchange network,
1 is a calling terminal, 2.5.7.11 is a switching network, 3 is another switching trunk, 4.6.10 is a trunk line, 9 is a special trunk, and 8 is a called terminal. First, in FIG. 1 showing the conventional connection system, when calling a calling terminal 8 in a different switching network B from a calling terminal 1 in an exchange network, dialing a special number such as O, The exchange 5 is connected to the exchange trunk 3 and activated via the trunk line 4, and then the dial pulse sent from the calling terminal is relayed by another exchange trunk 3 and received by the exchange 5. Thereafter, in a known manner, the exchange 5 drives the exchange 7 via the trunk line 6, and is connected to the target called terminal 8. In this way, the calling number of the called terminal in switched network B is not passed through switched network A. However, exchange network B
As mentioned earlier, it is more advantageous to connect the called number of the called terminal within exchange network A to the exchange that accommodates the called terminal via exchange network A. There are many cases. FIG. 2 shows an embodiment of the present invention that solves the above problem. When a calling terminal 1 of an exchange operator calls a calling terminal 8 of an exchange network B, the calling party dials a special number, for example, 9. do. With this dial 9, the exchange 2 connects the calling terminal 1 to a special trunk 9, which is connected to a known second
A dial tone is sent to the calling terminal 1. When the calling party hears the second dial tone, he dials the calling number of the called terminal, and the special trunk 9 receives and stores this and dials the number in the switching network B'' located at the beginning of the calling terminal number. Exchange machine 7
The number is translated into the number of the exchange 11 in the exchange network A adjacent to the own exchange, and the call number of the other exchange trunk is added to the translated number to drive the exchange 2. Thereafter, the exchange 2 is connected to another exchange trunk 3 by driving the exchange 11 via the trunk line 10 in a known manner. When the special trunk 9 is connected to the other exchange trunk 3 through the above route, the other exchange trunk 3 sends a response signal to the special trunk 9, so the special trunk 9 receives this and sends the previously stored called call signal. The calling number of the terminal is transmitted as an audio frequency signal. When the other exchange trunk 9 receives the calling number of the called terminal sent as the audio frequency signal, it converts it into a dial pulse that drives the exchange 7 and sends it to the exchange 7. Connect to the called terminal 8. Next, the above connection operation will be explained with reference to FIGS. 3 and 4. Figure 3 is an example of the block configuration of a special trunk.
The figure shows an example of a block configuration of an alternate switching trunk. The operation of the special trunk shown in Figure 3 is as follows:
1 receives an incoming call, the second dial tone generation circuit 22 sends out a second dial tone. Next, when the called number of the called terminal is received, the pulse reception storage circuit 23 receives and stores it, and the translation circuit 24 translates the number of the exchange accommodating the called terminal into the number of the adjacent exchange within the local exchange network. Then, the signal is sent out from the signal sending circuit 26 through the output terminal 28. When a response signal is received from the called exchange, response signal receiving circuit 2
7, the audio signal conversion circuit 25 is activated to convert the calling number of the called terminal stored in the reception storage circuit 23 into an audio frequency signal, and the signal is sent from the signal sending circuit 26 to the output terminal 2.
8. The operation of the other exchange trunk in FIG. 4 is such that when a call arrives at the input terminal 31 from the exchange, a response signal is sent out from the response signal sending circuit 36. Then, the calling number of the called terminal sent as an audio frequency signal is received by the audio signal receiving circuit 32, converted into a dial pulse by the pulse converting circuit 33, and sent from the pulse sending circuit 34 through the output terminal 35. . [Effects of the Invention] As described above, according to the present invention, connections between different telephone exchange networks can be made via the local exchange network, which enables connections that are advantageous in terms of cost and quality. .
