(by pressing the information button)
The relay for power outage operates and connects the line to the communication path switch side of the main device, making it possible to freely control line switching according to button operations on the telephone, and also to prevent power outage of the telephone device. When the line is automatically connected to the attached device, it is possible to make and receive calls using the attached device's attached telephone.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to block diagrams showing embodiments.

In the figure, a line 21 .
ρ22 is accommodated, and the contact p of the power failure relay PF
fl.

While the relay PF is in operation, it is connected to the communication path switch 3 side for exchange connection through each p fl, but when the relay PF is restored, it is connected to the main device 1 through a pair of communication lines 41 and 42. Each of the answering machines R5 and 52 is connected to the answering machine R5 and 52 as attached accessories.

In addition, incoming call detection circuits 61 and 62 for detecting ringing signals from lines 2 and 22 are bridge-connected to the call path switch 3 side of contacts pf1 and pf'', and also detect dialing signals to lines 2 and 22 when making a call. A dial transmission circuit 7 is connected thereto, and the relay PF is operated by a local power supply (2) applied via a resistor R in accordance with the output of the drive circuit 8.

On the other hand, a transmission circuit 9 for transmitting control data and receiving operation data, and a control section 10 consisting of a processor such as a microprocessor, a memory, etc. are provided. The control unit 1
0, the signal lines 221 to 22 are connected from the transmission circuit 9 to
transmitting control data via telephone 2;
31 to 23n via the signal lines 22+ to 22n, and provides this to the control unit 10. The control unit 10 receives the received information of the operation data and the incoming call detection circuit 6+, Control decisions are made by well-known means in accordance with the detection output of the communication path switch 3,
It controls the dial transmission circuit 7 and drive circuit 8 to perform various controls necessary for exchange connections, and also controls the transmission circuit 9 to transmit necessary control data.

The main device 1 uses the applicable power source AC as a power source, receives this power via the power switch SW, rectifies and stabilizes it by the power source section 11, and supplies it as a local power source V to each necessary section. While the power source AC is energized, the control unit 10 in principle gives a control signal to the drive circuit 8 to put the relay PF' into the operating state. However, in the event of a power outage of the power source AC, in response to the disappearance of the local power source V, The relay PF is supposed to be restored.

However, power supply AC rarely causes power outages in the current power situation, so 6D and relay PF are rarely used as a countermeasure against power outages. , 52.

That is, the telephones 23f to 23n are connected to the telephone lines 21+ to 2.
In addition to the telephone call circuit 31 connected to 1n, a group of buttons 32,
It includes an indicator light group 33, a control section 34 which is similar to the control section 10 but has a smaller configuration, and a transmission circuit 35, and includes, for example,
When a specific number indicating switching information is sent by operating a dial button in the button group 32, this is decoded by a well-known toshi control unit 34, converted into operation data indicating switching information, and transmitted via a transmission circuit 35. Because it is sent
When the transmission circuit 9 receives this, the control unit 1
0 is determined to be switching information by a well-known means, and the sending of the control signal to the drive circuit 8 is stopped to restore the relay PF.

For this reason, the lines 21 and 22 are connected to the answering machines 5+ and 52, and the attached telephones 241 and 242 can freely make and receive calls to and from the lines 2+ and 22.
If the absentee devices 5+ and 52 are set to the absentee operation mode, an absentee response is performed.

In response to the above, if a specific number separate from the above indicating the recovery information is sent by operating the dial button similar to the above, this is transmitted by the control unit 34 and the transmission circuit 35 as operation data indicating the recovery information. The control unit 10
is used to send the control signal to the drive circuit 8 again,
Since the relay PF operates and connects lines 2 and +2 to the entire communication path switch 3 side, each telephone set 231 to 23n can freely make and receive calls to and from lines 21 and 2t.

In addition, the control unit 34 controls each indicator light in the indicator light group 33 to turn on, turn off, or blink according to the received control data, thereby controlling the status of the lines 2+ and 2z and its own operation. It is used to display the status, etc., and the response status of the relay PF to the transmission of switching information and recovery information can be confirmed by displaying with a specific indicator light.

Therefore, by simply operating the switching information and recovery information buttons on any of the telephones 231 to 23n depending on conditions such as going out and returning home, or nighttime and daytime, the line 21.2□ can be switched to the answering machine 5+, St side. fart,
Alternatively, switching to the communication path switch 3 side υ can facilitate the switching operation with a simple configuration.

However, the answering machine 51, 52 should always be set to the operation mode when you are away, but if you use the attached telephone 24+ or 242 to answer an incoming call during a power outage, wait until the bell rings 2 to 3 times with the ringing signal. If you do not go off-hook during this period, the answering devices 5+ and 52 will automatically respond, so during a power outage, you can set them to the at-home operating mode if necessary.

As mentioned above, the frequency of power outages is extremely low.
Even if calls are made and received only using the answering device 5+ or 5 during a power outage, practically no inconvenience occurs.

In addition, the number of lines 2+ and 2t is determined depending on the situation and is 6D.In addition to providing a relay equivalent to relay PF for each line, switching information is determined for each line, and only the desired line is connected to the answering device. You may also switch to telephone number 231~
The button operations of 23n may be performed not only by the dial button but also by other function buttons, and a telephone capable of performing these operations may be specified.

In addition, the answering machine 5 and 52 include attached telephones 241 and 24.
2 may be used, and an answering device 51.5 may be used.
A separate control line may be provided between the main device 2 and the main device 1 to switch the operation mode.As for the attached equipment, in addition to the answering device 51, 52, a facsimile machine, a data terminal, etc. Various modifications are possible, such as being able to use various terminal devices that use the lines 2+ and 22, such as devices.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, by using a telephone installed near the user at all times, it is possible to freely switch connection to and restore connection to attached equipment of the line, and the configuration as a telephone device is particularly complicated.
