A free use service signal is sent out from the audio signal sending circuit. Then, the audio output circuit outputs the audio based on the free use service signal.

(Embodiment) FIG. 1 is a block diagram of a notification service system showing an embodiment of the present invention.

In the figure, POS is the telephone of a subscriber who has a contract for the notification service, LINE is the subscriber's line, and NW is the exchange. CE is an in-home device that is connected to the subscriber line LINE on the telephone manufacturer side (subscriber side). OE is an in-office device that connects the subscriber line LIN on the exchange NW side (office side).
It is connected to E.

The in-home device CE includes a subscriber-side vacancy detection circuit VDET1, a key human power device KEY, a service instruction output path SE, an amplifier circuit AMPI, and a speaker SP.

The subscriber side vacancy detection circuit VDETI constitutes a relay, and when the subscriber line is vacant, its relay contacts SWI, S
Close the WI and open it when a call is made or received. The contents of the request for the air utilization service are manually input into the key input device KEY by the subscriber. Service instruction sending circuit SE
sends a request instruction signal for an air utilization service based on the input contents of the key to the in-office equipment OE via the subscriber line LINE. The amplifier circuit AMPI receives and amplifies an audio signal, which will be described later, from the in-office device OE, and outputs the audio from the speaker SP. The amplifier circuit AMPI and the speaker SP constitute an audio output circuit.

The station equipment OE includes an office-side empty detection circuit VDET2, an instruction signal receiving circuit REC, a control circuit C0NT, and a clock circuit TI.
M, an audio signal sending circuit VE, and an amplifier circuit AMP2.

The office-side vacancy detection circuit VDET2 detects the vacancy of the subscriber's line and detects call origination or incoming call. The instruction signal receiving circuit REC receives the request instruction signal for the free use service sent from the service instruction sending circuit SE, and transmits it to the control circuit C0NT. The control circuit C0NT constitutes an instruction signal discrimination circuit, and when the office-side vacancy detection circuit VDET2 detects that the subscriber line LINE is vacant, the changeover switch SW2 is switched to the in-office device C.
E side, and when an outgoing or incoming call is detected, switches to the NW side of the exchange, and the instruction signal receiving circuit REC.
VE receives a request instruction signal, determines the request instruction signal, and transmits the determination result to the audio signal sending circuit VE when the clock circuit TIM indicates the time according to the time instruction.
to communicate. Based on the above-mentioned determination result, the audio service provider Michide circuit VE extracts and outputs the corresponding audio signal from among the audio signals of the air utilization service prepared in advance. The amplifier circuit AMP2 amplifies the audio signal and sends it to the subscriber line LINE.
The data is sent to the home device CE via the .

The operation of the above configuration will be explained below.

The subscriber line LI is detected by the subscriber side empty detection circuit VDETI.
When NE vacancy is detected, relay contact SWI is closed. When the office-side vacancy detection circuit VDET2 similarly detects vacancy, the result is transmitted to the control circuit C0NT, and the changeover switch SW2 is switched to the in-office device CE side. The above conditions will enable air utilization services from now on.

When the subscriber inputs the service number, service time, etc. from the key input device KEY on the home device CE side, a service request instruction signal is sent from the service instruction sending circuit SE to the subscriber line LINE.

On the intra-office device CE side, an instruction signal receiving circuit REC receives the request instruction signal and sends it to the control circuit C0NT. The control circuit C0NT analyzes and registers the service number, service time, etc. based on the request instruction signal. When the current time sent from the clock circuit TIM reaches the service time, the office side vacancy detection circuit VDET2 confirms whether the subscriber line LINE is vacant. When the availability of the subscriber line LINE is confirmed, the registered service number causes the audio signal sending circuit VE to generate an audio signal with the service content corresponding to the service number, and the amplifier circuit AMP2 generates an audio signal with the service content corresponding to the service number.
The signal is amplified and sent to the subscriber circuit LINE.

When a call is made or received during these services, the subscriber-side vacancy detection circuit VDETl and the office-side vacancy detection circuit VDET2
When an outgoing or incoming call is detected, the relay contact SW
1 is opened, the switching contact SW2 is switched to the exchange NW side, and the fact that the subscriber line LINE is in use is transmitted to the control circuit C0NT. Control circuit C0NT
Since the subscriber port GL I N E is in use, it instructs the audio signal sending circuit VE and the amplifier circuit AMP2 to stop the service, thereby stopping the service.

Addendum: When the registered time arrives, subscriber line LIN
If E is not vacant, the control circuit C0NT waits for it to become vacant and starts the service when it becomes vacant.

When the subscriber receives voice from these services, he sends out a confirmation signal using the key manual device KEY. When the control circuit C0NT receives the confirmation signal via the instruction signal receiving circuit REC, the service ends. However, if a call is made or received without this confirmation signal, the service waits for a free space and starts the service again. do.

(Effects of the Invention) As explained above, according to the present invention, by transmitting a request instruction signal for airspace service according to the instruction of the subscriber, an audio signal for airspace service is output, and the service is received by voice. This eliminates the need for a consignor. In addition, each element for providing airspace service is connected to the subscriber's line without going through an exchange, resulting in excellent economic efficiency in terms of facility usage and service.
