2. Description of the Related Art A conventional multi-connector will be described below with reference to FIGS. FIG. 4 is an example of multi-link connection of repeaters. FIG. 5 shows a concrete example of the striking circuit, which is the striking circuit in the repeater.

In FIG. 4, reference numerals 1 and 2 denote terminal devices,
The terminal device 1 is provided with a meeting circuit 1a for transmitting and receiving the set meeting information, and the terminal device 2 is also provided with the same meeting circuit 2a. The terminal device 1 and the terminal device 2 are provided with a function of multiplexing / demultiplexing transmission information.

Further, 3-1 to 3-4 are, for example, four-stage relay repeaters installed at regular intervals (about 40 to 80 kilometers) between the terminal device 1 and the terminal device 2, and each repeater is
3-1 to 3-4 are digital amplifiers 3a and 3b for reproducing / amplifying transmission information and separating / multiplexing transmission information and meeting information.
And a meeting circuit 3c for transmitting and receiving the set meeting information.

In FIG. 5, 31a and 31b are multiplexing parts for transmission information and meeting information, and 32a and 32b are separating parts for separating meeting information from transmission information. Reference numerals 33a to 33c are first to third selectors having switching contacts.

Reference numeral 34 is an encoder having an analog / digital conversion function, and 35 is a decoder having a digital / analog conversion function. Further, 36 is a microphone for transmitting, and 37 is a speaker for receiving.

In FIG. 4, for example, when voice information is transmitted from the terminal device 1 on the west side to the terminal device 2 on the east side, the terminal device 1
The analog signal is digitally converted by the encoder in the meeting circuit 1a to be coded, and then multiplexed in the multiplexing section to form transmission information, and the transmission information is sent out on the line.

The repeater 3-1 adds the transmission information from the terminal device 1 via the line to the digital amplifier 3a to reproduce and amplify it, and then the multiplexing information in the separating section in the communication circuit 3c. And the digital-to-analog conversion is decoded by a decoder to generate a strike sound from a speaker.

On the other hand, the repeater 3-1 performs analog-to-digital conversion of the meeting voice by the encoder in the meeting circuit 3c to code it, and multiplexes the coded meeting information in the multiplexing unit, and then the digital amplifier 3a. Via repeater 3-2.

Similarly, the repeaters 3-2 to 3-4 also sequentially reproduce / amplify the transmission information from the preceding stage, separate / multiplex the meeting information, and decode / encode the meeting voice, and finally the final stage. The transmission information from the repeater 3-4 is passed to the terminal device 2.

The terminal device 2 separates the meeting information from the transmission information, decodes the meeting information by digital / analog conversion in the meeting circuit 2a, and receives the meeting voice. In contrast to the above, for example, when voice information is transmitted from the terminal device 2 on the east side to the terminal device 1 on the west side, the terminal device 2 encodes the meeting voice by analog / digital conversion by the encoder in the meeting circuit 2a. After that, it is multiplexed in the multiplexing unit to form transmission information,
The transmission information is sent out on the line.

The repeater 3-4 adds the transmission information from the terminal device 2 via the line to the digital amplifier 3a to reproduce and amplify it, and then the multiplexing information in the separation section in the communication circuit 3c. And the digital-to-analog conversion is decoded by a decoder to generate a strike sound from a speaker.

On the other hand, the repeater 3-4 performs analog-to-digital conversion by a coder on the meeting voice in the meeting circuit 3c to code it, and multiplexes the coded meeting information in a multiplexer before the digital amplifier 3a. Via repeater 3-3.

Similarly, the repeaters 3-3 to 3-1 sequentially perform reproduction / amplification of transmission information from the preceding stage, separation / multiplexing of the meeting information, decoding / coding of the meeting voice, and the final stage. The transmission information from the repeater 3-1 is passed to the terminal device 1.

The terminal device 1 separates the meeting information from the transmission information, performs digital / analog conversion decoding of the meeting information in the meeting circuit 1a, and receives the meeting voice. For example, in FIG. 4, when voice communication is performed from the repeater 3-2 side to the repeater 3-4 side, a strike voice from an unillustrated microphone provided on the side is sent to the strike circuit 3c of the repeater 3-1. Then, the meeting circuit 3c performs coding by analog / digital conversion to create meeting information, the digital amplifier 3a multiplexes the meeting information with the transmission information, and the repeater 3-3 passes the transmission information through the repeater 3-3. -Send to -4.

The repeater 3-4 separates the meeting information from the transmission information by the digital amplifier 3a, decodes it by the digital / analog conversion by the meeting circuit 3c to create a meeting voice, and adds it to a speaker (not shown). To listen.

From the repeater 3-4 side, the repeater 3-
When sending a conferencing voice between the two parties, the procedure opposite to the above procedure can be used for sending and receiving. These operations are shown in FIG.
More specifically, the repeater 3-2 turns on the b side of the contacts of the first selector 33a and the third selector 33c.

Then, the meeting sound passed through the microphone 36 is coded by analog / digital conversion by the encoder 34 to create meeting information, and the meeting information is sent to the multiplexer 31b via the first selector 33a. In addition, the repeater 3 is multiplexed with the transmission information.
Send to side 4.

Also, the meeting information from the repeater 3-4 side is separated by the separating section 32b, and the separated meeting information is added to the decoder 35 via the third selector 33c and decoded by digital / analog conversion. To make a meeting voice and make a speaker
Listen at 37.

On the other hand, when the repeater 3-2 communicates with the repeater on the terminal device 1 side, the a side of the contacts of the second selector 33b and the third selector 33c is turned on. This enables transmission / reception between the repeater 3-1 and the repeater 3-4, for example.

Similarly, in the repeaters 3-1, 3-3, 3-4 shown in FIG. 4, when using a meeting line for a line test, for example,
The line settings are switched as shown in FIG.

[0022]

Therefore, in the case of making a call using the conventional meeting circuit, the call can be made by selecting the first selector and the third selector when talking with the direction of the terminal device 1 side. However, at the same time, a call cannot be made with the terminal device 2 side. In addition, there is a problem that it is necessary to switch the first selector 33a to the third selector 33c when talking with the direction of the terminal device 2 side.
