It is connected to the door phone call circuit 44 via. The door phone call circuit 44 is connected to a cross point switch 45 which will be described later.
It is connected to.

The coupling transformer 40 is connected to the output end of the hold tone generator 46 and the input end of the outside line dial tone detector 47, and is further connected to the push button earer 48 via the analog switch S3.
The output of the pushbutton/dial signal receiving section 501 and the external line input end of the cross point switch 45 are connected via analog switch S.

Furthermore, a sound source generator 5 outputs an audio signal such as a melody signal to a cross point switch 45 via an amplifier 7A.

Then, the audio signal from the sound source generator 51 is sent to the cross point switch 4.
7 amplifiers A1 to A are provided for amplification when superimposing the control line 6 on the control line 6, . The control circuit 57 processes the signal transmission and reception between these circuits, and is composed of a microcomputer or the like. In addition, G in Figure 4,・
... is a date circuit.

Next, the operation of this embodiment will be explained.

First, in this embodiment, when the power is turned on and the system starts, the control circuit 57 consisting of a one-chip microcomputer performs initial settings, and then enters a standby state to determine hook-off and further determine whether there is an incoming outside call. and processes an external line call, determines whether or not there is a doorphone call, and processes the doorphone call, determines whether or not there is an extension call, processes the internal line call, processes an external line call, and so on. Now, when you raise the handset of the general standalone telephone WiT to make an outside call, at this time, the switching contact 42B of the outside line switching relay Ryll is connected to the A contact side, that is, the cross point switch 45 side. Therefore, for example, the corresponding hook/guy pulse detection unit 55 detects the off-hook current generated by direct current connection by the telephone and inputs the detection signal to the control circuit 57. ,
. is turned on, and a pseudo transmission signal of 400 Hz is sent to the crosspoint switch 45 and the slave device 10 through the extension 5 through the date G3. At the same time, the control circuit 5
7 controls the slave device I/F display drive section 56 to display each slave device 1.
0... and notification unit) A's discrimination circuit 14 outputs a voltage signal that lights up a light emitting diode La for indicating that an outside line is busy. At this time, the light emitting diode Lb indicating 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 dial pulse detector 55. (
If the button dial type is used, when the button dial signal receiving section 50□) detects the signal, the control circuit 57 stops outputting the pseudo call signal and stores the dial data in the internal buffer memory.

Then, activate the 3 second timer. If the second dial signal (■) is detected while this timer is operating, it is determined that an outside call has been made. Second dial signal within these 3 seconds■
If there is no input, it is determined that the call is an extension call, and the extension call processing is performed. Now, 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 a signal for operating the DC connection section 39 is output.

When the line is closed, the outside line dial tone detection unit 47 detects the outside line dial tone and the detection signal is input to the control circuit 57.The control circuit 57 sequentially reads out the dial data stored in the buffer memory from the first one and switches the analog switch. The S controller and button dialer 48 are operated, or the dial relay Ryd is operated to sequentially send dial signals to the outside #12. At the same time, the data of the dial signal input from the general standalone telephone T is stored in the buffer 7 memory. In this way, the dial data from the general standalone telephone fiT is stored in the buffer memory at the same time as the dial signal is sent to the outside #12. Then, the dial data stored in the buffer memory runs out for a certain period of time (for example, a 5 second timer is activated and these 5 seconds are set as a certain period of time).
Once the time has elapsed, the next call will be made to an outside line. Incidentally, when sending the dial signal to the outside 4I2, the line connection is interrupted.

Of course, whether to operate the push button earer 48 or the dial relay Ryd is determined depending on the type of line.

For telephone calls, a coupling transformer 40, a mute analog switch S4, a cross point switch 45, a switching contact 42. ..., inside #! This will be done via 5.

By the way, after a dial signal is input from a general standalone telephone T connected to the remote control unit 10 and a pseudo call signal is output, if the next dial signal is not input within 3 seconds, the input dial data will be used as an extension number. Judgment and control circuit 5
7 is cross point switch 45 XS, which is turned on from OFF 7. X s3. Turn on. In addition, the light emitting diode La of each remote control unit 10 and notification unit A that had been turned on since off-hook is turned off, and at the same time, a voltage signal is sent to the remote control unit 1/F display drive unit to turn on the light emitting diode Lb indicating that the extension line is busy. output from 56. Further, the control circuit 57 controls the sound source generating section 51 to output an audio signal for calling an extension. This audio signal is sent out through the inner R5, and is superimposed and sent out through the cross point switch 45 Xs, .

Note that these transmissions are performed alternately. Now that the audio signal has been sent to the speaker 10 and the notification unit) A, the speaker 1
A ringtone will sound from 5. When the handset connected to the mobile phone 10 connected to the telephone number T is picked up by this ringing, the 7tsukuφ dial pulse detection unit 55□
detects this off state and sends a detection signal to the control circuit 57. The control circuit 57 switches the cross point switch 45 to XS2. is turned on, and #i5 of the remote control unit 10 on the calling side is connected to the extension 5 of the remote control unit 10 on the called side to establish a conversation state. And control #X6 glue, L,
Turn off the output of the audio signal for the extension call to the other #X5
A voice signal indicating that the extension line is busy is sent.

From now on, the general standalone phone f connected to the calling party's remote station 10
A call can be made between the iT and the general standalone telephone ff1T connected to the remote telephone 10 on the called side. At this time, after switching the external line switching relays Ry, 421 is maintained connected to the a contact side.

By the way, when an incoming call signal is input from outside #i2, the incoming call detection section 38 detects this incoming call signal and outputs an incoming call detection signal to the control circuit 57. When the control circuit 57 receives this incoming call detection signal, it stops the excitation of each outside line switching relay Ry, . . . and switches each switching contact 42 . ...Switch to the b contact side. Therefore, the general stand-alone telephone Iso T connected to each remote 10... is connected to the external line 2 through the extension 5, and each telephone fi
At T, the built-in bell will ring. At this time, the sound source generator 51 generates an audio signal indicating an incoming call, and sends it out via the crosspoint switch 45 and the control line 6, L, to the speaker 15 of each remote control 10 and notification unit A. Incoming calls can be notified more easily. Now, when the handset of the general standalone telephone fiT connected to a certain child center 10 is raised due to the ringing of a bell or a notification from the speaker 15, a communication current will flow through the line. This call current is detected by the call current detection circuit 41, and upon this detection, the control circuit 57 detects that one of the general standalone telephones T is turned off, and turns on the DC closing section 39.
At the same time, the external line switching relay Ryll... is energized to switch each switching contact 42,... to the a contact side. As a result, off-hook can be detected by the hook/dial pulse detection section 551..., and the control circuit 57 detects that the handset of the general standalone telephone T connected to the remote telephone 10 is picked up, and also detects this. At the same time, cross point switch 45 Xs.

0, connect outside #I2 and extension 5 of child separation 10,
This allows you to make outside calls.

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

First, when the handset of the fiT phone that 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 from the fiT phone, the control circuit 5
At step 7, this dial data is read, it is determined that it is a hold process, and the hold process is performed. In other words, cross point switch 4
5, turn off X5lo and turn on Xsz+Xs+y.

Then, by operating the hold music generating section 46, the coupling transformer 40
The hold tone melody signal is sent to the outside line 2 via the on-demand melody signal, and the call process is started while the DC connection section 39 is kept in the on state.

After entering the above-mentioned hold state, if the input dial data is other than "7" which designates an intercom call, an extension call is made and connection to the extension number corresponding to the extension number is made by the above-described extension processing. In addition, if the hold state continues for a certain period of time or more, the sound source generator 51 generates a hold alarm audio signal and sends the sound signal to each child separation unit 10... and notification unit A via control #16. The sound is transmitted and sounded from each speaker 15. To release the hold, it is sufficient to send a dial signal of "0" from any off-hook telephone T, and the control circuit 57 that detects the dial data of "0" stops the operation of the hold tone generator 46. , to control each part in the below outside line call state.

Now, when designated dial data for a door phone call is input after being put on hold, the control circuit 57 controls the door phone call processing.When transitioning from an outside line call state to a hold or door phone call, dial data of 0'' is input. Then, the Xsl corresponding to the outside line of the cross point switch 45 is turned off, and at the same time, the child separation I/F display drive unit 56 generates a voltage signal that also lights up the light emitting diode Lb that indicates that the extension line is busy. Apply to control M6 and separate 1 from each child.
0...and notification unit) A's light emitting diodes La, L
b are turned on respectively.

This is a hold process, and when the dial data of 7'' is input, the control circuit 57 determines that it is a doorphone call, turns off the Xs++ of the crosspoint switch 45, and at the same time turns off the Xs of the crosspoint switch 45 corresponding to the doorphone call line. Then, for example, the analog switch SI is turned on to connect the door phone 3 to the door phone call circuit 44 to enable a door phone call.

Note that the DC closing section 39 continues to be in the on state to maintain line closure. Also, the external line switching relay Ry, , is the switching contact 42. a
Maintain the state connected to the contact side.

By the way, in the process of making the above-mentioned doorphone call, the hold dial data "0" is sent out first, but the general standalone telephone T that is in the middle of an outside line call simply sends the dial data "7" and the doorphone call is sent after the hold process. You can also take calls.

In other words, when dial data "7" is detected, the control circuit 5
7 is a cross point switch 45, Xs.

is turned off, and Xs, , Xs, 3 are turned on. Then, operate the hold tone generation g46 to output the hold melody signal.
i1M and at the same time turn on the analog switch S to connect the door phone 3 to the door phone call circuit 44 and enable door phone calls.

Also, from the remote r/F display drive unit 55, the extension line is busy.
A voltage signal that also lights up the light emitting diode Lb that displays l0 is generated and applied to the control line 6, and the mustard 'a10...
and notification unit) light-emitting diodes La%Lb of A are turned on, respectively.

Incidentally, the DC closing section 39 continues to be in the on state as in the case described above, and performs various line closing operations.

The above explanation was about the call operation, but when a security signal or an emergency push button operation signal is input, the control circuit 57 causes the sound source generator 51 to generate an alarm audio signal, and each child's remote control 10... It is also possible to send an alarm sound to the notification unit A via the cross point switch 45 and the control line 6, L, and the respective speakers 15.

The connection terminal 34 of the notification unit A in the above embodiment is composed of a terminal 34a and a terminal screw 34b, but as shown in FIG. It may also be configured with a connecting terminal.

In the embodiments shown in FIGS. 2 and 7 above, the dimensions of the unit main body were made to correspond to the dimensions of three modules of ready-made wiring equipment, but even with one module as shown in FIG. Of course, two modules may be used as shown in FIG. 9.

[Effects of the Invention 1] The present invention provides a notification unit for a telephone system as described above, in which the unit main body is composed of a body and a cover, the above-mentioned speaker is built into the body, and the external dimensions of the unit main body are adjusted to the same size as a ready-made wiring device. In addition, the unit body is equipped with means for attaching to the mounting frame, and the unit can be attached to an embedded box using the mounting frame, so the user can be notified of the usage status of the line by voice.
