Abstract

PURPOSE:To discriminate an originating subscriber and to prescribe correctly an originating call destination to said subscriber, by reading an ID card issued to the originating subscriber by a card reader attached to each extension telephone connected to a private branch exchange. CONSTITUTION:A card reader 2 and a PB signal generator 3 are connected to each extension telephone 1 connected to a private branch exchange 5 via a changeover switch 4. When the telephone 1 is hooked off and dialing is given to an outside line, the switch 4 is automatically switched to the side of the reader 2. An originating subscriber reads his/her own ID card through the reader 2 and converts the contents of the card into PB signals through the generator 3. These PB signals are received by a PB signal receiver 7 of the exchange 5. Then a central processor 6 discriminates the originating subscriber and prescribes the use of an outside line according to the originating destination set for each prescribed originating subscriber. This suppresses the misuse of telephones to attain the titled system suited to a working center.

Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a calling destination regulation method for an exchange for specifying a calling destination by a caller.
O0゜〈Prior art and problems〉 Traditionally, this type of calling destination regulation system has been adopted in private branch exchanges to which many extension telephones are connected, and generally the calling destination is specified for each extension telephone. Met.

In other words, a caller with a narrow calling area (for example, a person who is permitted to call only within the premises) can also use an extension telephone used by a caller who has a wide calling area (for example, a person who is permitted to make outside calls as well as within the premises). conversely, if a caller with a wide calling area uses the extension telephone used by a caller with a narrow calling area, the caller can make a call to a wide area. The problem was that you could not make calls and had to select a phone each time.

<Object of the invention> The object of the present invention is to solve the above-mentioned conventional problems and to
The exchange determines the destination by recognizing D,
To provide a calling destination regulation system that allows a caller to specify the correct calling destination regardless of the telephone set used.

<Structure of the Invention> The calling destination control method of the exchange according to the present invention is such that a card reader is connected to a telephone, and when a caller makes a call to an outside line, the caller's IDE read by the card reader is connected to a stain removal machine. The system allows the central processing unit of the exchange to recognize the caller and specifies the destination of the caller's call.

<Embodiments of the invention> Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

A PR signal generator 3 connected to an extension telephone 1 and a card reader 2 is connected to a private branch exchange 5 by an automatic changeover switch 4. Note that a plurality of extension telephones 1 (not shown) are connected to the private branch exchange 5, and a card reader 2 is disposed in each of them.

Further, the central processing unit 6 connected to the private branch exchange 5 also connects to the PB signal receiver 7 also connected to the private branch exchange 5 to fake it.

The automatic changeover switch 4 normally connects the telephone 1 and the private branch exchange 5, but when the caller takes the extension telephone 1 off-hook and dials for an outside line, the automatic changeover switch 4 switches to the card reader 2 side. It's K.

The card reader 2 reads the caller ID from the card, sends it to the PB signal generator 3, and sends it to the PB signal generator 3.
Convert the signal by B times. This converted PR multiplied signal is sent to the private branch exchange 5 side.

The PR signal receiver 7 receives the PB multiplied signal. The central processing unit 6 has a function of recognizing a caller based on the PB multiplied signal received by the PB signal receiver 7 and defining the destination of the caller.

Next, the operation when the caller makes an outside call will be explained.

A caller takes extension telephone l off-hook and dials an outside line. Then, the automatic changeover switch 4 is automatically switched to the card reader 2 side. When the caller reads the card into the card reader 2, the read caller ID
is converted into a PR multiplied signal by the PR signal generator 3 and sent to the private branch exchange 5 side. On the private branch exchange 5 side, the PB signal receiver 7 receives the PB multiplied signal, and the central processing unit 6 recognizes the caller, thereby determining the destination of the call. In other words, if the predetermined calling destination includes an outside line,
Allows calls to outside lines, and disallows calls to outside lines for those whose call destination does not include an outside line (Effects of the Invention) As explained above, the call destination control system of the exchange according to the present invention is A cart reader is attached to a telephone connected to the card reader, and the central processing unit of the exchange determines the destination of the call using the caller ID read into the card reader. Even if you make a call, it is the correct call to the caller! It would be very effective if it could be defined.

Claims (1)

[Claims] When Card League is connected to a telephone and a caller makes a call to an outside line, the caller ID read by the card reader is used to introduce the caller to the central processing unit of the exchange connected to the telephone, and the caller's call is A method for regulating the originating area of an exchange that specifies the destination.
