JPH09321907A - Main telephone set with facsimile for two-circuit home telephone - Google Patents

Abstract

PROBLEM TO BE SOLVED: To simplify an operation and to decrease the number of parts of the main telephone set by setting the automatic transmitting/receiving operations, etc., for either of two circuits via a single operation part and using a single dial signal generation part that can be shared. SOLUTION: When the facsimile telephone number of the opposite party is dialed via an operation part 33 and a start button is pushed, a control part 30 detects whether a circuit 2 is idle or not. If the circuit 2 is busy, the part 30 detects whether a circuit 1 is idle or not. If the circuit 1 is idle, a PB signal generation part 34 is connected to the circuit 1. At the same time, the telephone number dialed via the part 33 is sent to the circuit 1 from the part 34 by a PB signal. Then a circuit switch circuit 41 is switched toward the circuit 1, and a CNG signal is sent to the opposite party. When the confirmation of facsimile is finished to the opposite party, a facsimile part 4 converts the image data read by an image sensor into facsimile signals via a modem 61 and transmits them to the circuit 1 via 2-wire/4-wire converter 43 and a circuit switch circuit 43.

That is, the line 1 is connected to the recorded message replay section 5 via the connection line 102, the 2-line to 4-line conversion circuit 51, and the modem 6. After that, a response message is sent to the other party. When a message is sent from the other party, it is recorded in a storage unit (not shown) of the recorded message replay unit 5. Extension telephones 81-
The message recording contents can be heard from 83 or the main telephone.

When listening to a message recorded by the call section of the master telephone, that is, the call circuit 7 and the handset 71, when the recording / listening operation is performed by the operation section 33, the control section 30 receives this request through the control line 13. The crosspoint switch 32 is controlled to connect the extension line 11 and the connection line 102, and further, the message record content is transferred from the storage unit of the recorded message replay unit 5 to the call circuit 7 via the 2-line to 4-line conversion circuit 51 and the modem 61. It is sent to the handset 71. Similarly, the recorded contents of the message can be heard from the extension telephone.

Next, the case of making a call from the extension telephone 81 will be described. After the off-hook, when a vacant line (designated as line 1) is selected by a station line button or the like, the control unit 30 receives this request on the control line 13 and controls the switching unit 35 to connect the selected line 1 and extension 11. Yes, dial after the dial tone arrives from the line. If the line is a PB line, the control unit 30 controls the crosspoint switch 32 to connect the PB signal generation unit 34 to the line 1 and the PB signal generation unit 3
The PB signal dialed by the extension telephone from 4 is transmitted to the line 1. If the other party answers, the call is established.

Next, a case of automatically transmitting a facsimile will be described with reference to FIG. When the other party's facsimile telephone number is dialed with the operation unit 33 and the button for starting is pressed, the control unit 30 detects whether or not the line 2 is idle. When the line 2 is not empty, it is similarly detected whether the line 1 is empty. If line 1 is free, PB
The signal generation unit 34 is connected to the line 1, and the number dialed by the operation unit 33 from the PB signal generation unit 34 is sent to the line 1 as a PB signal. Further, the line switching circuit 41 is switched to the line 1 side, and the CNG signal is sent to the other party. When the confirmation of the facsimile with the other party is completed, the facsimile section 4 converts the image data read by the image sensor into a facsimile signal by the modem 61, and the 2-wire-4 wire conversion circuit 43,
It is sent to the line 1 through the line switching circuit 43. When the image data transmission is completed, an end signal is transmitted and the original standby state is restored.

Further, a convenient example of using the master telephone of the present invention will be described. If there is an incoming call on line 2 while using line 1 this time, the user of the parent phone puts line 1 on hold on hold,
Press the line button of line 2 to respond. If the incoming call of line 2 is from a facsimile, press the communication button and the control unit 3
0 controls the line switching unit 41 to connect the 2-wire to 4-wire conversion circuit 43 to the line 2. Then, as described above, the facsimile section 4 outputs the image data sent from the facsimile of the other party on the paper. Also, the user of the parent telephone can capture the line 1 again and continue the call. By using this function, it is possible to proceed with the conversation while watching the image information of the facsimile coming from the other party while talking with the other party.
