本発明は制御情報伝送方式、特に同一国内に設置された
複数の国際電話交換機の間における回線群等の制御情報
の伝送のために使用される制御情報伝送方式に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a control information transmission method, particularly a system used for transmitting control information such as a group of lines between a plurality of international telephone exchanges installed in the same country. This invention relates to a control information transmission method.

送装置を設けて上記の情報の送受を行なっている。Conventionally, this type of control information transmission has been carried out by obtaining in advance information such as the busy state of all outgoing lines or failure status of other international telephone exchanges in the same country, and transmitting the control information via that international telephone exchange. This is used to prevent requests for international connection from being made repeatedly even though connection is not possible when attempting to establish an international connection. Therefore, although the amount of information is small compared to the total amount of control information for each call, it is essential for efficiently handling switching connections. Therefore, the domestic common line signaling system is used between international telephone exchanges to send and receive information on line groups, but if the national common line signaling system is not adopted, digital communication is carried out between these exchanges. Although the speed is relatively low, a dedicated data transmission device such as a data line or an analog data line using a modulator/demodulator is provided to send and receive the above information.

云う問題点を有している。However, the conventional dedicated data transmission equipment described above requires dedicated equipment such as transmitting/receiving equipment connected to the line and input/output equipment installed in the exchange, and furthermore, it is relatively easy to introduce these equipment. Even in exchanges using the storage program control system, which are considered to be the same, there is a problem in that it requires significant changes or additions to the programs for controlling these devices.

る。FIG. 1 is a block diagram of an embodiment of the present invention, in which a domestic trunk line is provided between two international telephone exchanges installed in the same country, and both exchanges have at least one line group to the same destination. In Figure 9, which shows a case in which the status of line groups is communicated to each other, two international telephone exchanges (hereinafter referred to as AGS and BGS) 1 and 2 are ordinary electronic exchanges for international telephone exchanges. , each call route switch network (hereinafter referred to as 5W) 10 is equipped with a trunk device for domestic lines (

ると、ＣＰｔＪ１４に送信準備の完了を伝える。The operation of transmitting control information in FIG. 1 will be explained below. For example, when transmitting control information from B5G2 to AGS1, the CPU 14 of B5G2 is designated for transmitting control information with vacant 5DR12. TRK
II via 5WIO. This BGS2 T
Since the RKII is connected to the 5DR12, it sends a start signal to the TRKII of the AGS 1 in the same way as a normal domestic line, and when it receives the start completion signal from the TRKII of the AGSI, it informs the CPtJ14 of completion of transmission preparation.

ととなる。On the other hand, when the TRKII of the AGSI receives the activation signal from the partner TRKII, it notifies the CPU 14 of activation. Therefore, this CPU 14 knows that it is the activation of TRKII for transmitting control information, and connects TRK 11 and the vacant REC 13 via 5WIO, and also connects this RECl 3
The CPU processes the received signal as control information.
An identification code is added to the state memory corresponding to the REC 13 provided in the REC 14. Also, AGSI's TRKII is R
By being connected to ECl3, it sends a start-up completion signal to the other TRK 11. Next, CPU14 of BGS2
Instructs the 5DR12 to transmit the blockage information of the line group to be transmitted according to the format shown in Figure 2. At this time, the number of digits sent from the 5DR12 is 4 digits per line group times the number of line groups to be transmitted. , which is different from the normal number of selected numbers. Further, in the AGSI, the numbers received by REClB are sequentially sent to the CPU 14, and the CPU 14 obtains the blockage information of the line group according to the format of the control information.

く少なくて済むと云う効果がある。As explained above, the present invention does not require the installation of dedicated data transmission equipment, and uses just one or two trunk devices for inter-office calls, which are usually installed in large numbers in one exchange, for this purpose. This makes it possible to transmit a relatively small amount of control information by reusing the selection signal, which has the effect of requiring almost no additional equipment and fewer changes to the processing program. .
