Next, the operation of the entire system shown in FIG. 1 will be explained based on the circuit shown in FIG.

Now Monular Consensus) 11. When the handset of the telephone 12 connected to is raised, the outside line switching relay R,
After switching Y++, the hook/dial pulse detector 30 detects off-hook and sends the detection signal to the control circuit, since it is connected to the A contact side, that is, the cross-point switch 21 side. 31. The control circuit 31 turns on XS+o of the crosspoint switch 21 and sends a pseudo transmission signal of 400 Hz through the date G to the modular outlet 11. through the crosspoint switch 21 and extension 8I. At the same time, the control circuit 31 controls the display ■/F display 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 installed in each modular outlet 11. Consen) 111...
The light-emitting diode provided at the terminal to indicate that the extension line is busy is controlled to be turned off.

This transmission continues until the dial signal is input, and the first dial signal ■ is sent to the hook 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 home job 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. 21 within the last 3 seconds! If there is no input of the dial signal ■, 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 that is subsequently input is sequentially stored in the buffer memory, and the DC connection section Outputs a signal to operate 17.

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.The control circuit 31 sequentially reads out the dial data stored in the buffer memory from the first one and searches for the switch. child S, and push-button earphone 23 or dial relay Ryd to sequentially send dial signals to outside line 5.
to be sent to. At the same time, the data of the dial signal input from the telephone set 12 is stored in the buffer memory.

In this way, the dial data from the telephone 12 is stored in the buffer 7 memory at the same time as the dial signal is sent to the outside line 5. When the dial data stored in the buffer anomaly is exhausted and a certain period of time has elapsed, the next call is made to an outside line. Incidentally, when sending the dial signal to the outside line 5, the Mffl connection is interrupted. Operate push button earer 23 or dial relay Ryd
Of course, whether or not to operate it depends on the type of line.

The telephone call is then carried out through the coupling transformer 14, the mute switch element S4, the cross point switch 21, the switching contact r3, the extension line 8. This will be done through.

Next, the operation when calling an extension will be explained.

First, a dial signal is input from the telephone W112 connected to the Moziera outlet 11°, and after a pseudo call signal is output, if the next dial signal is not input within 3 seconds, the input dial data will be transferred to the extension number ( For example, the control circuit 31 determines that the cross point switch 21 is connected to the monofilament outlet 11□) and turns it on from off-hook.
Turn off the Turn on Xsl to set a call path.

Further, the light-emitting diodes of the mono-radial outlets 111, which have been lit since off-hook, are turned off, and at the same time, the display 17F display drive section 29 outputs a voltage signal that turns on the light-emitting diodes indicating that the extension line is busy. 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□...
For example, the signal line 7 of the notification unit 92 is sent out through the X gos of the cross point switch 21.
It is sent superimposed on □. Note that these transmissions are performed alternately. Now, the notification unit 92 to which the audio signal has been sent emits a ringing tone from the speaker. When the handset of the telephone 12 connected to the moziera outlet 112 is picked up due to this ringing, the hook/dial pulse detection section 302 detects this off-hook and sends a detection signal to the control circuit 31.

The control circuit 31 stops the generation of the audio signal based on this OFF switch, and also closes the cross point switch 2.
1 x 82? Turn on the modular outlet 111
extension 8. and Ms2 of the modular outlet 112 are connected to establish a talking state.

From now on, things 1 la outlet 11. The telephone 12 connected to the
J! 112 can be made. At this time, the external line switching relay RFz maintains the switching contact "," connected to the a contact side.

In addition, when making a simultaneous call, if the corresponding telephone is connected to a telephone other than the telephone 12 that made the call! Monogram outlet 11 connected to 12
A sound signal is sent from the sound source generator 27 to the notification units 9 and 10 through each signal M7, and a ring tone is emitted from the speaker 43 of each notification unit 9 and the notification unit 10. After that, the telephone that made the call is The audio signals from 12 are sent through the cross point 21 to be superimposed on each signal M7, and are reproduced and audible by the respective notification units 9 and 10. At this time, if you pick up the telephone fi 12 connected to one of the monofila outlets 11, you can make an extension call. Further, when adjusting the volume, it can be done by switching the changeover switch SW of the notification unit 10, for example.

When an incoming call signal is input from the outside line 5 during standby, the incoming call detection section 13 detects this incoming call signal and sends the incoming call detection signal to I#l.
It is output to the l111 circuit 31. When this incoming call detection signal is input, the control circuit 31 switches each outside line switching relay Ryl+...
Stop the excitation of ・and switch each switching contact ``1...'' to the B contact side. Therefore, each monoera outlet 11...
The telephone R12 connected to . When the handset of the telephone 12 connected to the monoera receptacle 111 is raised due to this ringing, for example, a communication current will flow through the line. This communication current is detected by the communication current detection circuit 13, and upon this detection, the control circuit 31 detects that one of the telephones 12 is turned off, turns on the DC connection section 17, and simultaneously switches on the outside line switching relay Ry, . ..., and each switching contact "
Switch 1... to the a contact side. As a result, the 7-guyal pulse detection section 30. ..., off-hook can be detected, and the control circuit 31 connects the monoera outlet 11. detects that the handset of the telephone 12 connected to is picked up, and at the same time as this detection turns on X5lo of the cross point switch 21, connects the outside line 5 and M81 of the monoera outlet 111, This allows you 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 12 during an outside line call is not on-hook and a dial signal corresponding to hold, for example 0@, is sent from the telephone 81T, the 'III control circuit 31 reads this dial data and processes the hold. It is determined that this is the case, and the process is put on hold.

In other words, the cross point switch 21, Xsl. Turn off and turn on X s + l + X s I 7. Then, the on-hold tone generating section 15 is operated to send out the on-hold tone melody signal to the outside 11A3 via the coupling transformer 14, and the process shifts to a call process in which the DC closing section 17 is maintained in the on state.

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

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 mononilla outlet 11. ... to the respective notification units 91... and v10 via the signal line...
It is designed to make people more aware. To release the hold, it is sufficient to send a 0'' dial signal from any 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 control each part to return to the original outside line call state.

Also, when designated dial data for a doorbell call is input after being put on hold, the control circuit 31 controls the doorphone call processing. First, the designated dial data of 0" is input and corresponds to the outside line of the crosspoint switch 21. Xs+
. is turned off, and further the X St corresponding to the extension line is turned off.
y 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 I/F drive section 29 generates a voltage signal that also lights up a light emitting diode to indicate that the extension line is busy. . . , to light up the light emitting diodes for inner #I attenuation display and outer line display, respectively. This is a hold process, and when the dial data of 17" is input, the control circuit 31 determines that it is a doorphone call and turns off the crosspoint switch 21 X5ll, and at the same time crosspoint switch 2 corresponding to the doorphone call line.
Turn on X9+t of 1. Then, for example, the switch element Sl is turned on to connect the door phone 5 to the door phone call circuit 26 to enable a door phone call.

The DC closing portion 17 continues to be in the on state and maintains the #lWi connection. Also, the external line switching relay RF++... is the switching contact r
1... is connected to the a contact side and maintained in the negative state.

In addition, when there is a call from the door intercom slave device 6, the audio signal of the chime sound of the door intercom call generated from the sound source generator 27 is transmitted to the signal line 71 under the action of the control circuit 31, cross point 21, etc.・Through each Hochi Uni y) 9+
[Effects of the Invention] When a call is received from an outside line, the present invention forms a communication path between the telephone connected to the extension and the outside line, and also transmits the call from the telephone connected to the extension to the extension. When there is a call, a signal line is connected to the exchange unit that forms an extension communication path and sends audio and voltage signals via the signal line when the extension is called, when all telephones connected to the extension are called, when the extension is called, etc. In the notification unit of the telephone exchange system, which is equipped with a speaker that is connected to the main body block and broadcasts the audio signal sent through the signal line, the speaker is internally installed in the main block, and the surface of the main block is covered with a decorative cover. Because it is a cover, you can use a decorative cover with a design that matches the interior of the place where it will be installed or a design of your choice, without being tied to the design of the main body cover.Moreover, during installation, the decorative cover can be removed from the main body. Since the net can be removed for installation, accidents such as damage to the net or damage to the decorative cover can be prevented.
