B ₆ , and emit the light for displaying the inside busy line. Output a voltage signal to turn off the diode.

The transmission of the pseudo outgoing signal of 400 Hz continues until the dial data is input, and when the first dial data is detected by the dial pulse off-hook detector 31a (PB receivers 24, 25, 26 in the case of push dial type). The control circuit unit 1 stops the output of the pseudo transmission signal of 400 Hz and stores the dial data in the built-in buffer memory. Then, the control circuit unit 1 operates the built-in 3-second timer. When the second dial data is detected during the operation of the 3-second timer, the control circuit unit 1 determines that the call is an outside line. If the second dial data is not input within this 3 seconds, the control circuit unit 1 determines that the call is an extension call and performs an extension call process. In the case of an outside line call, the control circuit unit 1 sequentially stores dial data to be input subsequently in a buffer memory and sends a signal for operating the DC closing unit 6.

When the dial tone detection unit 9 detects an external line dial tone due to line closure and inputs the detection signal to the control circuit unit 1, the control circuit unit 1 reads the dial data stored in the buffer memory from the first. sequentially reading, and how to operate the or dial pulse transmitting unit 10 operates the analog switches S _3, S ₄ and PB dialer 21 sends sequentially dial signal to the outside line L. At the same time, the control circuit unit 1 stores the dial data input from the general single telephone F ₁ in the buffer memory. That is, at the same time as sending the dial signal to the outside line L, the general single telephone F ₁
The dial data from is stored in the buffer memory. Then, when the dial data stored in the buffer memory is lost and a fixed time (for example, a 5-second timer is operated to set 5 seconds as the fixed time) elapses, the external telephone call is started.

When sending the dial signal to the outside line L, the control circuit section 1 interrupts the circuit closing. Either operate the analog switch S _3, S ₄ and PB dialer 21, or, whether to operate the dial pulse transmitting unit 10, it is set by the type of line. And the call is

Circuit part 1
To enter. Then, the control circuit unit 1 detects from the detection signal that the facsimile F ₆ has automatically arrived, turns off the excitation of the outside line switching relay 36c, connects the switching contact 36c ₁ to the b contact side, and connects the facsimile F ₆ to the facsimile F ₆ . It is connected to the external line L via the internal line W _1a of the child device B ₆ .

The facsimile F ₆ connected to the outside line L sends an incoming signal to the other facsimile via the outside line L.
The partner facsimile machine starts sending data after receiving the incoming signal. The facsimile machine F ₆ opens the DC connection when it finishes receiving the data. Then, the polarity reversal detection unit 4 detects that the current has stopped flowing to the outside line L and outputs it to the control circuit unit 1, and the control circuit unit 1 causes the outside line switching relay 36.
The excitation of c is turned on to connect the switching contact 36c ₁ to the contact a side, and the DC closing part 6 is turned off.

[0036] By the way, if, generally single line telephone F ₁ by the pseudo incoming _signal, ... the fifth ringing tone of the F ₅ to until you have Hatsuna, for example Taking the general single line telephone F ₁ handset, dial pulse off-hook detection part 31a detects the current caused by the DC閉結by general single line telephone F _1, and inputs the detection signal to the control circuit unit 1. Then, the control circuit unit 1 detects from the detection signal that the handset of the general single-use telephone F ₁ has been picked up and has arrived, and outputs a signal for operating the DC closing unit 6 and excites the external line switching relay 31c. Switch off, switching contact 31
c ₁ is connected to the contact b side, and the general single telephone F ₁ is connected to the slave unit B.
_It is connected to the external line L via the internal line W _1a corresponding to ₁ . The general independent telephone F ₁ sends an incoming signal to the other party connected by the outside line L.

When the resident who picks up the handset of the general independent telephone F ₁ hears the unique tone signal sent by the facsimile of the other party and recognizes that the other party is a facsimile, the procedure for calling the extension line during an outside line call is made. Then, the desired facsimile F ₆ is called to switch the outside line transfer. That is, first, the resident holds the handset of the general single-use telephone F ₁ during an outside line call by hand, and performs on-hook for a short time within 1 second with the other hand. Then, the outside line L
The current flowing through is interrupted only for a short time within 1 second when the direct current connection of the general telephone F ₁ is temporarily opened within 1 second. This interruption of the current is detected by the polarity reversal detection unit 4 and input to the control circuit unit 1. When the control circuit unit 1 detects an on-hook for a short time within 1 second,
Turn on the excitation of the external line switching relay 31c to switch the switching contact 31c.
₁ is connected to the contact a side, and the general single telephone F ₁ is connected to the slave B ₁
Is connected to the analog switch network 29 through the extension W _1a corresponding to the above, and the pseudo transmission signal of 400 Hz from the 400 Hz transmission section 27 is output to the general single telephone F ₁ through the 400 Hz filter section 28.

Then, the resident recognizes that the main device A is in a waiting state for inputting dial data, and the line currently captured by the main device A is transferred to the child device B ₆ to which the facsimile F ₆ is connected. In order to switch to the corresponding extension W _1a , dial data “6” corresponding to a predetermined operation that is determined in advance.
Is input from the general single telephone F ₁ . Then, the dial data "6" is sent to the dial pulse off-hook detector 3
1a (PB receiver 24 if push dial type,
25, 26) detects and sends to the control circuit unit 1. Then, the control circuit unit 1 stops the output of the pseudo transmission signal of 400 Hz, outputs an active signal to the 16 Hz transmission unit 30, and outputs the calling signal transmission unit 36a composed of a photocoupler.
16 Hz is sent to the light receiving side of 36d, and a call sending switch signal that is active for 1 second and nonactive for 2 seconds is sent only to the light emitting side of the calling signal sending unit 36d including a photo coupler through the input / output expansion port 2. To do.

The calling signal sending unit 36d outputs a pseudo incoming signal from the light receiving side of the calling signal sending unit 36d to the facsimile F ₆ via the extension W _1a corresponding to the child device B ₆ . Facsimile F ₆ automatically receives an incoming call in response to the pseudo incoming signal. The dial pulse off-hook detector 36a detects a current generated by DC closing due to an automatic incoming call of the facsimile F ₆ , and inputs this detection signal to the control circuit unit 1. Based on the detection signal, the control circuit unit 1 detects that the facsimile F ₆ has automatically arrived, turns off the excitation of the external line switching relay 36c, connects the switching contact 36c ₁ to the b contact side, and sets the facsimile F ₆ as a slave. It is connected to the external line L via the internal line W _1a corresponding to the device B ₆ . Facsimile F ₆ sends an incoming signal to the other facsimile via external line L. After receiving the incoming signal, the partner facsimile machine recognizes the facsimile machine F ₆ and starts sending data. Facsimile F
₆ opens the DC connection when it finishes receiving the data.
Then, the polarity reversal detection unit 4 detects that the current has stopped flowing in the external line L, and outputs it to the control circuit unit 1. Then
The control circuit unit 1 turns on the excitation of the external line switching relay 36c to connect the switching contact 36c ₁ to the contact a side and turns off the DC closing unit 6.

When it is desired to make an extension call during an outside call or to make a doorphone call, the call can be put on hold. For example, if the general single telephone F ₁ during an outside line call is on-hook for a short time within 1 second,
The control circuit unit 1 turns on the excitation of the external line switching relay 31c to connect the switching contact 31c ₁ to the a contact side, and connects the general individual telephone F ₁ to the analog switch network via the extension W _1a corresponding to the slave unit B _1. It is connected to 29 and 400Hz from the sending part 27 400
A pseudo transmission signal of Hz is output to the general single telephone F ₁ through the 400 Hz filter unit 28.

[0041] Therefore, residents, the main device A recognizes that it is now waiting for input of the dial data, and inputs the dial data "0" corresponding to the pending is predetermined from a general single line telephone F _1. The control circuit unit 1 reads the dial data "0" sent from the general single line telephone F _1, determines that the pending process, performs hold processing. That is,
The control circuit unit 1 operates the holding tone sending unit 8 to send the holding tone melody signal to the outside line L via the coupling transformer 5, and shifts to the calling process while maintaining the DC closing unit 6 in the ON state. To do.

The control circuit unit 1 is in the above-mentioned holding state.
After that, the dial data to be input is the dial that specifies the doorphone.
If it is not "7", it is judged as an extension call and the extension
By processing, the extension number is connected to the slave unit. Also,
Sound is generated when the hold status continues for a certain period of time
A voice signal of a hold alarm sound is generated in the section 13 to

Control each part to the state.

After the holding process, the control circuit section 1 performs the intercom conversation process when the dial data "7" designating the intercom conversation is input. That is, in the case of shifting from the outside line call state to the hold or the intercom call, the control circuit unit 1 turns off the portion of the analog switch network 29 corresponding to the outside line line when the dial data “7” is input, and the outlet. A voltage signal for turning on the light emitting diode during the external line talk and the light emitting diode during the internal line talk is supplied from the display power supply unit 22 to the control line W corresponding to the slave units B _1, ... B _6.
Send to _1b . Then, the control circuit unit 1 determines that it is a doorphone call, and turns on a portion of the analog switch network 29 corresponding to the doorphone call line, and at the same time, the doorphone C _1,
The intercom of the visitor in C ₂ is connected to the intercom communication circuit section 12 through the intercom monitoring control section 11 to enable intercom communication.

[0044] Incidentally, when the intercom call by reserving process, together with the DC閉結unit 6 maintains the circuit closing to continue the on-state, external switch relay 31c, ... 36c are switching contact 31c _1, ... 36c ₁ Is maintained at the a-contact side.

Although the above description has been about the call operation and the facsimile operation, the control circuit section 1 uses the security signal from the alarm unit and the emergency push button E.
Sound signal is generated by the sound generation unit 14, and the sound signal of the alarm is sent to the control line W _1b corresponding to the slave units B _1, ...

According to the first aspect of the present invention, when an incoming signal is input from the telephone line, the incoming signal is sent only to the telephone and only the telephone is sounded when the incoming signal is input, but the predetermined time is set. After the lapse of time, an incoming signal is sent not only to the telephone but also to the facsimile to sound the telephone and the facsimile, so that the resident who is the operator sets the selection switch to the facsimile side when going out as in the past. However, after I got home, I forgot to reset the selection switch on the telephone side, and even if a call came in, the fax answered and I could not receive the call. When you are on the telephone side, you will not be able to receive a fax due to a facsimile, and you can automatically receive with a telephone on one telephone line. Good operability by suitably connecting the Akushimiri, an effect that it provides a facsimile response control method.

According to the second aspect of the invention, even if an incoming signal from the facsimile is erroneously taken off-hook by the telephone due to sounding of the telephone, it can be transferred to the facsimile. In addition to the effect, it is possible to provide a facsimile response control method that is more suitable and has good operability by connecting a telephone and a facsimile that automatically receives to one telephone line.

According to the invention of claim 3, when an incoming signal is input from the telephone line, the incoming signal is sent only to the telephone and only the telephone is sounded at the beginning, but after a predetermined time elapses. Sends an incoming signal not only to the telephone but also to the facsimile to sound the telephone and the facsimile. Therefore, when the resident who is the operator sets the selection switch to the facsimile side when going out, as in the past, , When I got home, I forgot to reset the selection switch on the telephone side, and even if a call came in, the fax could not answer and I could not receive the call. When you are on the other side, there is no possibility that you will receive a fax and cannot receive it, and you can automatically receive with a telephone for one telephone line. Good operability by suitably connecting the Kushimiri, an effect that it provides a home telephone exchange.

According to the invention described in claim 4, even if the incoming signal from the facsimile is erroneously taken off-hook by the telephone due to sounding of the telephone, it can be transferred to the facsimile. In addition to the effect, it is possible to provide a home telephone exchange that is more suitable and has good operability by connecting a telephone and a facsimile that automatically receives to one telephone line.
