Now mononilla outlet 11. phone 1'j1 connected to
When the handset 12 is raised, the switching contact r1 of the outside line switching relay Ryl l is connected to the a contact side, that is, the cross point switch 21 side, so the hook dial pulse detection unit 30+ is turned off. is detected and a detection signal is input to the control circuit 31. The control circuit 31 turns on the X slo of the cross point switch 21 and sends a pseudo transmission signal of 400 Hz through the date G to the modular outlet 11. Send to. At the same time, the control circuit 31 controls the display I/F attenuation drive unit 29 to output a voltage signal that lights up the light emitting diode for indicating that an outside line is busy, which is connected to each mononilar outlet 111. At this time, the same thing happened) 11.・
The light emitting diode provided at . . . to indicate that the extension line is busy is turned off.

This transmission continues until the input of the dial signal, and the first dial signal (■) is sent to the dial pulse detector 30. (
If it is a bush dial type, when the bush dial signal receiving section 162) detects it, the control circuit 31 stops outputting the pseudo call signal and stores the dial data in the built-in buffer memory. Then, I set the 3-second timer for my office job to work. If the second dial signal (■) is detected while this timer is operating, it is determined that an outside call has been made. If the second dial signal ■ is not input within these 3 seconds, it is determined that the call is an extension call, and the extension call processing is performed.In the case of an outside call, the data of the dial signal to be input subsequently is sequentially stored in the buffer memory. At the same time, a signal for operating the DC closing section 17 is output.

When the line is closed, the outside line dial tone detection unit 28 detects the outside line dial tone and the detection signal is input to the control circuit 31, and the control circuit 31 sequentially reads out the dial data stored in the buffer memory from the first dial data to the switch element. Activate S3 and push button earer 23 or operate dial relay Ryd to sequentially send dial signals to outside #I.
5. At the same time, the data of the dial signal inputted from the telephone set 12 is stored in the buffer memory.7 In this way, the dial data from the telephone set 12 is stored in the buffer memory at the same time as the dial signal is sent to the external AS. Then, when the dial data stored in the buffer memory is used up and a certain period of time has elapsed, the next call is made to an outside line. Incidentally, when sending the dial signal to outside #i5, the line connection is interrupted. Of course, whether to operate the push button ringer 23 or the dial relay Ryd is determined by the type of line. , switching contact r0, of which 88. This will be done through.

Next, the operation when making an extension call 1 will be explained.

First, a dial signal is input from the telephone 8!12 connected to the 11゜ outlet, and after the pseudo call signal is output, if the next dial signal is not input within 3 seconds, the input dial data will be The extension number (for example, mononira console) 112) and f1 are set, and the control circuit 31
turns off the X5IO of the cross point switch 21 that is turned on from off-hook, disconnects the outer M5, and also disconnects the inner #I8. Turn on Xs to set the call bus to .

1g from the earth's off-hook, the light emitting diodes of each monofilament outlet 11 that were lit turn off, and at the same time a voltage signal is output from the 1/F display drive unit 29 that lights up the light emitting diodes indicating that the extension line is busy. let Further, the control circuit 31 controls the sound source generating section 27 to output an audio signal for calling an extension. This audio signal is extension 8□...
・It is also sent out through the cross point switch 2J.
For example, the signal M1 of the notification unit 9□ is transmitted through X5o5 of
2 is superimposed and transmitted. Note that these transmissions are performed alternately.6 Now, the notification unit 9□ to which the audio signal has been sent emits a ringing tone from the speaker. This ringing causes the phone fi! connected to the modular outlet 11□! 2
When the handset is taken off, the hook/dial pulse detection section 302 detects this off-hook and sends a detection signal to the control circuit 31.The braking circuit 31 stops generating the audio signal based on this off-hook. and Xs2 of the cross point switch 21. Turn on the telephone 12 and connect the extension 81 of the modular outlet 111 and the extension 82 of the modular outlet 112 to make a call.The telephone 12 has since been disconnected from the modular outlet 111.
A call can be made between the telephone connected to the modular outlet 11□ and the telephone 12. At this time, the external line switching relay RVz remains connected to the 7 terminals, 1 to 8, and the α side after switching.

In addition, when making a general call, a sound signal is sent from the sound source generator 27 through each signal [7] to the notification units 9 and 10 to the modular outlet 11 connected to the corresponding telephone 8!12 other than the telephone 12 that made the call. The speaker and the speaker 43 of the notification unit 10 make a call, emit a sound, and then the phone that makes the call! f! 12
The multiple audio signals are superimposed and sent to each signal line 7 through the cross point 21, and are sent to the respective notification units 9 and 10.
It will be more replayed and audible. At this time, if the telephone 12 connected to any of the modular outlets 11 is picked up, an extension call can be made. Also, set the volume to i1M! If you want to adjust the amount, you can save $119 by switching the changeover switch SW1 of the notification unit 10, for example.

When an incoming call signal is input from outside #I5 during standby, the incoming call detection section 13 detects this incoming call signal and outputs an incoming call detection signal to the control circuit 31. When the control circuit 31 receives this incoming call detection signal, it stops the excitation of each outside line switching relay RylI... and switches each switching contact r1... to the b contact side. Therefore, each mononilla consen)11. Telephone W112 connected to ... is connected to outside lI! through extension 8゜...
5, and a built-in bell will ring in each telephone 12. This ringing can cause, for example, the modular outlet 11. When the handset of the telephone 12 connected to the telephone 12 is raised, speech current will flow through the line. This call current is detected by the call current detection circuit 13, and the control circuit 3 detects that one of the telephones 12 is turned off.
1 is detected, turns on the DC closing section 17, and at the same time excites the external line switching relays Ry, . . . , and switches each switching contact r,
...Switch to the a contact side. As a result, the 7-turn/Guillard pulse detection section 30. Off-hook can be detected in . and an outside line 5 and a modular outlet 11. Of these, M8. ... to make it possible to make outside calls.

Furthermore, if you want to make an extension call during an outside line call or make a doorphone call, you can put the call on hold.

First, when the handset of the telephone W112, which is in the middle of an outside line call, is not on-hook and a dial signal, for example 0'', corresponding to a hold is sent in advance from the telephone T, the control circuit 3
In step 1, this dial data is read, it is determined that it is a hold process, and the hold process is performed.

That is, the cross point switches 21, Xs, , are turned off, and X S 1+ * X S ) 7 is turned on. Then, the held music generator 15 was operated to send the held music melody signal to the outside line 5 via the coupling transformer 14, and the DC closing unit 17 was kept in the ON state! Shifts to i-ma call processing.

After entering the above-mentioned hold state, if the input dial data is other than "7" specifying an intercom call, an extension call is made and the extension number is connected to the modular outlet 11 by the extension process described above.

In addition, if the hold state continues for a certain period of time or more, the sound source generator 27 generates an audio signal of a hold alarm sound,
Each modular outlet 11. Signal #iI to ...
and the respective notification units 9゜... and 1
It is designed to be notified starting from 0. To release the hold, all you have to do is send a dial signal of "NO" from one of the off-hook telephones 12, and the control circuit 31 that detects the dial data of 0" stops the operation of the hold tone generator 15 and returns to the original state. It controls each part to make an outside line call.

Further, when designated dial data for a doorphone call is input after being put on hold, the control circuit 31 controls the doorphone call processing. First, the specified dial data of 0" is input, and the X s corresponding to the outside line of the cross point switch 21 is input.
Io is turned off, and Xs corresponding to the extension line is
, 7 and Xs corresponding to the extension tone line are turned off, and the hold tone generator 15 is operated to transmit the hold tone.

At the same time, the display r/F drive section 29 generates a voltage signal that also lights up the light emitting diode that indicates that the extension line is busy, and applies it to signal #171... to light up the light emitting diodes for the extension line display and the outside line display, respectively. Let it happen. This is a hold process, and when the dial data of 7'' is input, the control circuit 31 determines that it is a doorbell call and turns off the crosspoint switch 21, X3., and at the same time switches the crosspoint switch corresponding to the doorphone call line. 2
Turn on X513 of 1. For example, a switch element S.

is turned on to connect the door phone 5 to the door phone call circuit 26 to enable door phone calls.

The DC connection unit 17 continues to be in the on state and maintains the connection of the line 7. Also, the external line switching relay Ryz... is the switching contact r1...
・Keep the state connected to the a contact side.

Further, when there is a call from the doorphone remote control unit 6, under the action of the control circuit 31, cross point 21, etc., the audio signal of the chime sound of the doorphone call generated from the sound source generator 27 is transmitted to the signal line 7. ... through each notification unit 91
... and 10 to report [Effect of the Invention 1] The present invention provides a component storage section for storing components such as speakers in the center, and a mounting frame section is integrally connected to both ends of the component storage section. , consists of a main body block in which the back surfaces of the component storage part and the mounting frame part that come into contact with the exposed mounting surface are formed on the same surface, and the mounting frame part has a mounting hole that corresponds to the embedded box that is commonly used for ready-made wiring devices, and an embedded hole.
