JPH02143665A - Absence call system from interphone set - Google Patents

Abstract

PURPOSE:To make reception to a visitor even when a subscriber is absent from its home by sending a pocket bell call number to a public telephone circuit network when a call comes from an interphone slave set to an interphone master set. CONSTITUTION:When a subscriber of an interphone master set 1 goes out from its home, the subscriber sets the absence mode by an absence mode setting circuit 1-11 and a pocket bell call number and an identification code are set by a number code setting circuit 1-8. When the subscriber goes out from its home and a call signal comes from an interphone slave set by a visit of a visitor. The call signal is sent to a public telephone circuit network 3 via a trunk line interface circuit 1-4. In the arrival of the identification code from the subscriber, the password is collated with the stored password and when the person of the code is verified, the circuit 1-4 is connected to a slave set interface circuit 1-6 to allow the subscriber to communicate the visitor.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a method for calling an absent telephone subscriber from a visitor intercom and enabling a conversation between the visitor and the telephone subscriber. The present invention relates to an absentee calling method from an intercom, and particularly to an absentee calling method from an intercom in which an absent telephone subscriber is called by a pager.

[Conventional technology]

When a visitor arrives while the telephone subscriber is absent, the following devices enable conversation between the visitor and the subscriber via intercom equipment, telephones, and public telephone lines:
For example, the method disclosed in Japanese Patent Application Laid-Open No. 62-57346 is known. According to this publication, when a telephone subscriber is away due to going out, absence information and out-of-home telephone number information are set in the telephone in advance. Now, if a visitor makes a call from the intercom when the subscriber of the telephone number is absent, the telephone will be placed in an automatic dialing state on the condition that the absence information is set, and the out-of-home telephone number will be the subscriber's line. The call is automatically sent to the public telephone line via the telephone, and the call is made to the person outside the home. By answering this call from a telephone outside the home, the telephone subscriber is able to have a conversation with the visitor.

[Problem to be solved by the invention]

However, according to the above-mentioned publication, telephone subscribers are not always away from home, and even when they are away from home, they are unable to respond to visitors.

SUMMARY OF THE INVENTION An object of the present invention is to provide an absentee call system from an intercom that allows an absent telephone subscriber to more reliably respond to a visitor when the visitor arrives.

[Means to solve the problem]

The above object is achieved by paging the telephone subscriber using a pager when a visitor arrives while the telephone subscriber is absent.

[For production]

Assuming that telephone subscribers carry a pager in advance,
In the case of absence, absence information and pager call number information are set by the telephone subscriber. If a visitor makes a call from the intercom with these information set, the pager will be called based on the pager calling number, provided that the absence information is set, and the call will be answered by a call from the nearest telephone. By responding with a sound and sending a PIN code, the telephone subscriber is able to greet the visitor. The PIN code is to prevent a third party from interacting with the visitor in vain, and only if the PIN code from the telephone subscriber matches the preset one, the telephone subscriber will be able to enter the visitor. It is possible to respond to

By the way, when a pager is called due to the absence of a telephone subscriber, or when there is no response from the telephone subscriber even after a certain period of time has elapsed since the call, a voice message is sent to the visitor to the effect that the call has been answered. In this case, the customer service will be more favorable.

〔Example〕

Hereinafter, the present invention will be explained with reference to the accompanying drawings.

The figure shows the block configuration of an example of an intercom base unit according to the present invention that is installed in a house, and shows the relationship between the slave unit (installed at the entrance outside the house) and the public telephone line network.

As shown in the figure, a switching circuit 1-3, which is a main component of the intercom base unit 1, is connected to a public telephone line 1! via a central office line interface circuit 1-4 and a subscriber line 2. ! 3 is also connected to the intercom handset 4 via the handset interface circuit 1-6.
However, a handset 1-1 is further accommodated via a telephone interface circuit 1-2.

Therefore, intercom base unit 1 is intercom base unit 4
It is designed to function not only as a base unit for the telephone, but also as a telephone housed in the public telephone line network 3.

That is, 1. In normal times, the switching circuit 1-3 is switched in a predetermined manner under the control of the control circuit 1-9, so that the communication between the handset 1-1 and the public telephone line 3 or the handset 1-
1 and an intercom handset 4 are connected. However, in certain cases, other telephones accommodated in the public telephone line 3 are connected to the intercom slave unit 4 via the intercom base unit 1, so that the telephone subscriber associated with the intercom base unit 1 can You can now talk to visitors visiting your home from your phone.
It is something that The connection between the intercom handset 4 and another telephone is specifically made when the telephone subscriber is called by a pager, and this will be explained in detail as follows.

That is, when the telephone subscriber associated with the intercom base unit 1 is absent due to going out, the subscriber sets the absent mode setting circuit 1-11 to the absent mode and sets the number/code in advance. A pager calling number and a password are set from the circuit 1-8. Of course, if these call numbers and codes have already been set as the same, no new settings are required. The pager calling number and password from the number/code setting circuit 1-8 are stored in the number sending circuit 1-5 and response return/code discrimination circuit 1-7, respectively, under the control of the control circuit 1-9. , telephone subscribers can go out.

Now, when a telephone subscriber goes out and is absent and a call is received from the intercom handset 4 due to a visitor's visit, the call is detected by the handset interface circuit 1-6 and then sent to the control circuit 1. -9 will be notified. Based on this notification, the control circuit 1-9 first checks the mode status of the absent mode setting circuit 1-11, but in this case, since the absent mode 2 is set, the switching circuit 1
-3 is switched and controlled, the number sending circuit 1-5
is connected to the office line interface circuit 1-4, so that the office line interface circuit 1-4 is also placed in the transmitting state. Thereafter, under the control of the control circuit 1-9, the pager calling number is transferred from the number output circuit 1-5 to the public telephone line 3 via the switching circuit 1-3, the office line interface circuit 1-4, and the subscriber line 2. It is now sent out.

As a result, the pager carried by the absent subscriber is called wirelessly.

Meanwhile, in parallel with the sending of the pager calling number, the message storage/sending circuit 1-10 is connected to the slave unit interface circuit 1-6 via the switching circuit 1-3 by the switching control of the switching circuit 1-3. The message storage/transmission circuit 1-10 displays a voice message to the visitor via the intercom handset 4 to the effect that the telephone subscriber is not present and the customer is being called by telephone. This display puts the visitor in a standby state to wait for the result of the call. Note that the message storage/sending circuit 1-10 has a voice message appropriately created in advance stored in a ROM or the like.

When the sending of the pager calling number is completed, the 1-station line interface circuit 1-4 returns a response via the switching circuit 1-3.
It is connected to the code discrimination circuit 1-7 and set to the called state, but in such a state, when the telephone subscriber calls his home from the nearest telephone (such as a public telephone) in response to the pager's ringing, In this case, the incoming call is detected by the response return/code discrimination circuit 1-7.If an incoming call is detected, the response return/code discrimination circuit 1-7 sends a response signal to the incoming call. After being sent through the reverse route, the response return/code discrimination circuit 1-7 is placed in a standby state in order to verify the personal identification code from the telephone subscriber. Eventually, if there is a PIN code from the telephone subscriber, it will be compared with a pre-stored PIN code to confirm whether or not the subscriber is the subscriber. When the identity of the subscriber is confirmed, the 1-station line interface circuit 1-4 is connected to the handset interface circuit 1-6 via the switching circuit 1-3, allowing the telephone subscriber to respond to the visitor. It is something. When the visitor restores the intercom handset 4 at the end of the reception, the connection between the office line interface circuit 1-4 and the handset interface circuit 1-6 is released, and the connection to the public telephone line network 3 is restored. A signal is sent out.

By the way, a timer provided in the control circuit 1-9 monitors the time from the end of sending out the pager calling number. If there is no notification from the response return/code discrimination circuit 1-7 within a certain period of time that the PIN code matches, the visitor will receive a voice message informing him/her that the telephone subscriber cannot be called. , is displayed from the intercom handset 4 via the message storage/sending circuit 1-10, the switching circuit 1-3, and the handset interface circuit 1-6. After this display is made, all circuit states are restored by the control circuit 1-9 and the system is ready for the next visitor. If the visitor really wants to talk to the telephone subscriber, he/she can call again from the intercom handset 4.

〔Effect of the invention〕

As explained above, according to claim 1, a telephone subscriber can receive visitors to his/her home even when he/she is away from home. Furthermore, according to claims 2 and 3, the service quality for customers will be improved.
