Description

[Detailed Description of the Invention] [Summary] A connecting means for mutually connecting a subscriber line, a telephone, and an intercom for visitors, and transmitting a set telephone number to the subscriber line when a call is received from the intercom while the user is absent. This makes it possible to answer the intercom from a telephone outside the home.

[Industrial application field]

The present invention relates to an intercom transfer system that allows a customer to respond to an intercom from a telephone outside the home.

In addition to subscriber telephones connected to the public communication network, ordinary homes often have an intercom system for visitors installed between the entrance and the inside of the home.

In such an intercom system, it is desirable that the user be able to respond to customers from outside the home, even when the user is out.

[Conventional technology]

FIG. 3 is a diagram showing an example of a conventional intercom system.

In FIG. 3, a telephone 3 is installed in a home 1 and is connected to a public communication network (not shown) via a subscriber line 2. As shown in FIG. In addition to the telephone 3, an intercom 4 provided at the entrance and an intercom 5 provided at an appropriate location within the house are connected to each other.

When a visitor operates the intercom 4, the resident can receive a response using the intercom 5 installed in the house 1.

However, if the resident goes out, even if a visitor operates the intercom 4, it is impossible to respond to the visitor.

[Problem that the invention seeks to solve]

As is clear from the above explanation, in conventional intercom systems, residents can only respond to visitors when they are at home, and when they go out, it is impossible to do so using the subscriber phone at their location. there were.

[Means for solving problems]

FIG. 1 is a diagram showing the principle of the present invention.

In Figure 1, subscriber line 2 accommodated in the public communication network
and connection means 100 for mutually connecting the telephone 3 and the intercom 4 for visitors, and when a call is received from the intercom 4 while the telephone 3 is set to be absent, a preset telephone number is connected to the subscriber line. Number sending means 2 to send to 2
00 is provided.

[Function] That is, according to the present invention, if a resident who goes out sets the telephone number of his/her outing place in advance, when a visitor makes a call from the intercom, the intercom will call the person who is going out via the subscriber line and the public communication network. It will be connected to the previous telephone, allowing residents to receive calls from visitors.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram showing an intercom transfer method according to an embodiment of the present invention. Note that the same reference numerals indicate the same objects throughout the figures.

In FIG. 2, the connecting means 100 includes a central office line circuit 6,
A telephone circuit 7, an intercom circuit 8, a connection circuit 9 and a control circuit 10 are provided, and a number sending circuit 11 and a telephone number setting circuit 12 are provided as a number sending means 200. is provided.

In FIG. 2, when a resident makes a call from the telephone 3, the telephone circuit 7 detects the call from the telephone 3 and notifies the control circuit 10. The control circuit 10 that has been notified of the call from the telephone 3,
The connection circuit 9 is controlled to connect the telephone circuit 7 and the office line circuit 6, and to set the office line circuit 6 to a calling state. From now on, the dialed digits sent from the telephone 3 are sent to the telephone circuit 7.
, is sent to the subscriber line 2 via the connection circuit 9 and the intercom circuit 8. When the called party answers, the resident can make the call.

Next, when a call arrives at subscriber vA2 from a public communication network (not shown), office line circuit 6 detects the calling signal arriving from subscriber line 2 and notifies control circuit 10 of the call arrival. The control circuit 10, which has been notified of the incoming call to the subscriber line 2, controls the connection circuit 9 to connect the office line circuit 6 and the telephone circuit 7, and also sends a calling signal from the telephone circuit 7 to the telephone 3. When the resident answers using the telephone 3, the telephone circuit 7 and the central office line circuit 6 are put into a communication state, and a telephone conversation becomes possible.

Next, when the visitor makes a call from the intercom 4, the intercom circuit 8 detects the call from the intercom 4, and the control circuit l
Notify O. The control circuit 10 that has been notified of the call from the intercom 4 controls the connection circuit 9 to connect the intercom circuit 8.
and the telephone circuit 7, and sends a calling signal from the telephone circuit 7 to the telephone 3. When the resident answers using the telephone 3, the telephone circuit 7 and the intercom circuit 8 are put into a talking state, allowing the resident to respond to the visitor.

Next, when the resident goes out, he or she sets the absence button 13 attached to the telephone 3 and also sets the telephone number setting circuit 12.
Set your subscriber phone number when you are away from home. When a visitor makes a call from the intercom 4 in such a state, the intercom circuit 8 detects the operation of the intercom 4 in the same way as described in fT1,
The control circuit 10 is notified.

When the control circuit 1O that has been notified of the call from the intercom 4 identifies that the absence button 13 is set, it controls the connection circuit 9 to connect the number sending circuit 11 and the office line circuit 6, and also connects the office line circuit 11 to the office line circuit 6. After setting the circuit 6 to the calling state, each digit of the telephone number set in the telephone number setting circuit 12 is sequentially transmitted to the number sending circuit 11. Number sending circuit 11
represents each number transmitted from the control circuit 10 to the connection circuit 9
The information is sequentially transmitted to the subscriber line 2 via the central office line circuit 6, and a resident outside the home is called via a public communication network (not shown).

When the digit sending circuit 11 sends out all the digits of the telephone number, the control circuit 10 controls the connection circuit 9 to connect the intercom@line 8 and the office line circuit 6.

When the resident answers the telephone while away from home, the central office line circuit 6,
It is connected to the intercom 4 via the connection circuit 9 and the intercom circuit 8, so that it is possible to respond to visitors. When the visitor restores the intercom 4, the connection between the intercom circuit 8 and the office line circuit 6 via the connection circuit 9 is released, and the connection from the subscriber VA2 to the outside location is also released.

As is clear from the above explanation, according to the present embodiment, when the resident goes out, the resident sets the absentee button 13 and further sets the telephone number of the out-of-home telephone number in the telephone number setting circuit 12. It becomes possible to respond to visitors who call from a telephone outside the home.

Note that FIG. 2 is only one embodiment of the present invention, and for example, the configurations of the connecting means 1 ([) and the number sending means 200 are not limited to those shown in the figure, and may be modified in many other ways. However, the effects of the present invention remain the same in either case.

〔Effect of the invention〕

As described above, according to the present invention, when a resident goes out and sets the telephone number of his/her outside place in advance, the resident can respond to a visitor who calls from the intercom while he/she is away from the telephone from his/her outside telephone number via the public communication network. It becomes possible to respond.
