Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an announcement machine, particularly of the recording and editing type used in electronic transducers.

(Prior art) Conventionally, in telephone exchanges, callers are asked to change numbers, line failures, etc.
Information services such as weather forecasts were provided, and tape recorders with pre-recorded data on Endless Chee 1 were used for these services, but recently, in order to provide even more detailed services, recording and editing type announcement machines have been used. There is Retsu.

This recording/editing type announcement machine records multiple words and phrases in advance in an IC memory, etc. by PCM encoding, etc., receives editing information from a switchboard, and sends out the edited version. It can be used as an analog voice signal, and without being demodulated by a digital exchange (
Many transmit 1'CM codes as they are.

(Problem to be Solved by the Invention) Accordingly, this announcement machine has its output terminal connected to one of the call terminals of the call path switch of the exchange, and obtains editing data and control signals directly from the central control unit of the exchange. It is configured to do this.

Therefore, when installing an announcement machine, a connection device with the central control device is required.Furthermore, this connection device must be changed depending on the exchange, which requires a lot of versatility.Furthermore, the announcement machine is separated from the exchange. The problem is that in order to install it at a certain location, all the equipment must be used at a distance corresponding to the distance.

The purpose of the present invention is to eliminate the above-mentioned problems, and to use in-band multi-frequency signals as control signals for editing data, so that it can be easily connected to any converter and can be connected remotely from the exchange. To provide an announcement machine that does not depend on a part of the machine even if it is installed.

(Means for Solving the Problem) The announcement machine of the present invention uses a recorder-type audio signal connected to one (sending side) of a set of communication path terminals of a communication path switch of a four-wire exchange. A transmitting circuit, an in-band multi-frequency signal receiver connected to the other end of the communication line terminal (receiver (111)), and a control circuit that performs editing control of the audio signal transmitting circuit according to the signal received by this receiver. It is composed of:

In this configuration, the central control unit of the exchange connects the in-band multi-frequency transmitter installed as general equipment and the in-band multi-frequency receiver of this announcement machine via the communication path switch, and transmits the multi-frequency signal. Control information such as data is sent from the device to the announcement machine using a multi-frequency signal, and then the serviced line and this announcement machine are connected via a communication path switch. The Seco Announcement Machine repeats editing and playback according to the data obtained from the multi-frequency receiver until this connection is released.

Furthermore, if the 4-wire switch is a time-division digital switch, the voice signal sending circuit is a multiplexed PCM voice signal sending circuit that matches the multiplicity of this digital switch, and the in-band multi-frequency signal receiver also has a multiplicity. Multiplexed PC with the same
As an M multi-frequency receiver, the control circuit performs multiple control, thereby constructing a multiplexed announcement machine.

The operation in this case is the same as when sending an audio signal to a single line as described above in terms of line correspondence.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention, showing a case where the connected exchange is of an analog type, and also shows a part of this exchange necessary for explaining the embodiment. In the figure, an announcement machine (hereinafter referred to as ANN) 1 includes a recording/editing type voice signal sending circuit (hereinafter referred to as VSSDR) 11 and a push button dial signal receiver (hereinafter referred to as VSSDR), which is a type of in-band multi-frequency signal receiver.
The control circuit 13 receives a received signal from the PBFLEC 12 and controls the VSSDRII. On the other hand, the output of VSSDRII is connected to the sending side of a set of communication path terminals of the communication path switch (hereinafter referred to as NW) 21 of the exchange, and the receiving side of this communication path terminal is P
Connected to the input of BREC12. In addition, NW21 has multiple line circuits (hereinafter referred to as LC) 22, PBREC2
4. Contains normal communication line equipment such as push button dial signal transmitter (hereinafter referred to as PBSDR) 25, and these equipment are connected to the NW.
21 constitutes an ordinary four-wire electronic exchange controlled by a central control unit (hereinafter referred to as CC) 26. Furthermore, LC
22 has a 4-wire to 2-wire conversion circuit, and a telephone 23 is connected via a subscriber line.

In the above configuration, ANM is sent to the telephone 23 that made the call.
When making an announcement from 1, CC26 first
Connect PBSDR25 and ANMI via W21. Next, the CC 26 sequentially transfers code numbers corresponding to words, phrases, etc. predetermined by ANMI to the PBSDR 25 according to the content of the announcement. Therefore, PB8DR
25 sends out this code number in the form of a push button dial signal. This dial signal is received by PBREC12 and given to C0NT13 as a code number string. C0
When the NT13 receives the final code provided in the code number string, for example, after 0.2 seconds, the code numbers are sequentially transferred to VSSDR.
.

11 to send out an audio signal. On the other hand, when CC26 finishes sending out all dial signals from PBSDR25, it immediately disconnects the communication path between ANMI and FBSDR25,
VSSD to set up the communication path between ANML and LC22
The voice signal from the RII is transmitted to the telephone set 23. This audio signal is sent to the on-hook LC22 of the telephone 23 by cc26.
The recovery code number is sent repeatedly until the PB8DR25 and ANMl are connected and the recovery code number is sent to ANMl.

Although the above embodiment assumes that the exchange is of an analog type, the announcement machine shown in FIG. 1 can be used even if the exchange is a digital exchange with a time-division switch. Furthermore, if the communication path switch handles multiplexed PCM codes, the audio output circuit in FIG.
The push-button dial signal receiver is also a multiplexed PCM push-button dial signal receiver used in this type of exchange, and the control circuit is also time-divisionally controlled. It is clear that announcements can be made independently of the lines.

Furthermore, in the above embodiments, the announcement transmission is terminated by an instruction from the central control device, but it is also possible to set a time limit and terminate the announcement, or to set a number of announcements and terminate the announcement. do not have.

(Effects of the Invention) As described above in detail, according to the present invention, the announcement machine can be connected as a terminal device housed in a communication path switch without directly connecting the announcement machine and the central control device. Therefore, it can be installed regardless of the exchange model, and the installation location is not limited to the installation location of the exchange.
