Abstract

PURPOSE:To listen to preceding information during recording by providing a recording terminal and a reproducing terminal for a talkie service device to a channel switch of a wired broadcast telephone exchange and providing a trunk connected to the terminals and two tape recorders. CONSTITUTION:When a specific telephone set 6 hooks off to send a specific telephone number and a special dial, a central processing unit 2 connects the specific telephone set 6 and a channel terminal 11 to give a recording command to a control circuit 31. When the telephone set 6 hooks on, the central processing unit 2 gives a command of the end of recording to the control circuit 31. The control circuit 31 changes over a switch SA to a switch SB. The state of the switches SA and SB is held till the command of the end of recording comes by the controller 31. When a specific telephone number for talkie service is sent from a general subscriber telephone set 9, the central processing unit connects the telephone set 9 to the channel terminal 12 to give a command of reproduction to the control circuit 31. Then the talkie service is executed from a take recorder having recording.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a talkie service device, and more particularly to a talkie service device in a cable broadcast telephone exchange system using an electronic exchange.

[Conventional technology]

Conventionally, in this type of talkie service equipment, a wire broadcast telephone exchange is equipped with a tape recorder for recording and playback, and recording is performed by sending a specific telephone number and special dial from a specific telephone. By transmitting the above-mentioned specific telephone number from another general subscriber's telephone, the recorded contents can be played back and listened to from this tape recorder. That is, a recording/playback trunk is connected to one terminal of the communication path switch of the exchange, and a tape recorder is connected to this trunk.

[Problem that the invention seeks to solve]

However, the talkie service equipment of the conventional cable broadcast telephone exchange system described above uses one trunk and performs recording and playback via one tape recorder.
If a request to play back the recorded content is received from a general subscriber's phone while a recording is being accepted from a specific phone, the recording will take priority and playback will not be possible, and a busy tone will be played to the person who wishes to listen to the playback. The drawback is that it requires connection to another tape recorder and a voice prompt such as ``Currently recording, please call again later''.

SUMMARY OF THE INVENTION An object of the present invention is to provide a talkie service device that is equipped with a telephone line trunk of a cable broadcasting telephone exchange and two tape recorders, thereby making it possible to listen to information during and before recording.

[Means for solving problems]

The talkie service device of the present invention is used in a cable broadcast telephone exchange system using an electronic exchange, and provides a first communication terminal for switching and connecting one communication path terminal of a communication path switch of the electronic exchange to the recording inputs of two tape recorders. a second changeover switch that switches and connects another communication path terminal of the communication path switch to the playback output of the two tape recorders; The tape recorder is configured to include a control circuit that controls the connection to the tape recorder by the first and second changeover switches differently from each other, and the two tape recorders.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. In the figure, 1 is a call path switch of an electronic exchange for cable broadcasting, 2 is a central processing unit of the electronic exchange for cable broadcasting, 3 is a talkie service trunk connected to two communication path terminals 11 and 12 of the communication path switch 1; 4 and 5 connect the recording input terminals 41 and 51 respectively to the talkie service trunk 3.
Tape recorder A and tape recorder B, 6, which have playback output terminals 42 and 52 respectively connected to the two input terminals of switch SB of talkie service trunk 3, are connected to the two output terminals of switch SA of The specific connected telephone 7 is a general subscriber telephone connected to the call path switch 1. Also, the central processing unit 2
It has a storage for storing processing programs for ordinary cable broadcast telephone exchange and for performing exchange operations, and a control program for the talkie service trunk 3. Yet another talkie
The service trunk 3 has a control circuit 31, which controls the holding and switching of the switches SA and SH and the tape recorders A4 and B5 under instructions from the central processing unit 2.

In the above configuration, when a specific telephone 6 makes a call and sends out a specific telephone number and special dial, the central processing unit 2 connects this specific telephone 6 and the call path terminal 11 in the same manner as before. , gives a recording instruction to the control circuit 31.

The control circuit 31 immediately gives a recording instruction to, for example, a tape recorder A4 connected by the switch SA. When a specific telephone 6 goes on-hook, the central processing unit 2 gives an instruction to the control circuit 31 to end recording. Therefore, the control circuit 31 returns the tape recorder A4 to the starting point, confirms that the tape recorder B5 is not in use, and switches the switches SA and SB. The states of the switches SA and SB are maintained until an instruction to end recording is received from the control device 31. Further, when a specific telephone number for talkie service is sent from the general subscriber telephone 9, the central processing unit 2 connects the telephone 9 to the communication path terminal 12 and gives a reproduction instruction to the control circuit 31. There, a talkie service is provided from a recorded tape recorder.

〔Effect of the invention〕

As explained above, the present invention uses a talkie service trunk that is connected to two communication line terminals and has two sets of changeover switches and their control circuits, and two tape recorders, thereby performing conventional processing. The advantage is that the talkie service in the cable broadcast telephone exchange can be continued without interruption even during recording, with almost no changes.
