First, in the guide message storage process, the operator inputs a message input selection of a guidance message to be stored, a number and a playback time of a message using a message input selection key, a message number key and a message time key of the key input unit 151 And the like.

At this time, if the message input selection is a telephone, the voice data from the extracting unit 154 is used. If the voice input from the A / D converting unit 155 is a microphone or a cassette tape, (155) is controlled by the guidance broadcast control unit (152) and is switched.

At this time, if the message input selection is a microphone or a cassette tape, the operator inputs the guidance message through the microphone to the input terminal of the A / D conversion unit 153 or plays the cassette tape to input the guidance message.

Then, the voice of the guidance message is modulated into digital voice data in the A / D conversion section 153 and applied to the switch section 155.

On the other hand, if the message input selection is a telephone, the operator's voice data from the telephone set receiving the telephone number set for recording the guidance message (which can be operated by adding a password to protect the access of the general subscriber) Is allocated to the time slot channel, is output to the time switch 130 after being loaded on the sub-highway, and the above-described extraction unit 154 receives the same.

Then, the extracting unit 154 extracts the voice data stored on the predetermined time slot channel on which the guidance message is placed under the control of the announcement control unit 152, and applies the extracted voice data to the switch unit 155.

Then, the serial voice data outputted from the switch unit 155 is converted into parallel voice data of a predetermined bit (8 bits) again by the serial / parallel converter 156 and outputted.

Next, the parallel voice data is temporarily stored in the temporary storage unit 157 under the control of the announcement control unit 152, and is read and applied to the guidance message storage unit 158. [

Next, the guidance message storage unit 158 stores the parallel voice data from the temporary storage unit 157 at the corresponding position set corresponding to the message number based on the control from the guidance broadcast control unit 152, The message time from the control unit 152 is also stored together.

Meanwhile, when the guide messages are stored in the guide message storage unit 158 for each type, the exchange transmits a corresponding announcement message to the corresponding subscriber's phone according to the situation to perform announcement broadcasting. .

First, the announcement control unit 152 reads a guidance message based on control of an upper processor (not shown). First, the guidance message storage unit 158 is controlled to read out the guidance message.

Then, the parallel voice data read out from the guidance message storage unit 158 is converted into serial voice data in the P / S converter 159, and then applied to the output unit 160 again.

The output unit 160 outputs the frame synchronization signal from the timing position 130 and the voice data from the parallel / serial conversion unit 159 on the basis of the reference clock signal to the corresponding The subscribers can listen to the announcement messages to the receiver of the telephone based on the time slot interchange of the time switch 130 by transmitting them to the time switch 130 via the sub highway cable.

As described above, according to the present invention, it is possible to conveniently record a guidance message used in the entire electronic exchanger at a remote place remote from the exchange using a general subscriber telephone connected to the exchange.
