Abstract

PURPOSE:To utilize its own abbreviated dial number by registering a pass word number by each subscriber so as to store the abbreviated dial number into a storage means of a key telephone master set in the unit of subscribers so as to allow a subscriber to input its own pass word number from an optional pushbutton telephone set. CONSTITUTION:A data interface circuit DINF 14 of a key telephone master set 1 receives an input data from a data line 4 and a key telephone set T2n and the input data is sent to a CPU 16 via an input/output interface circuit I/O INF 15. The CPU 16 decodes the input data and when it is judged to be a request of an abbreviated dial, a pass word number registered in a RAM 17 coincident with the input pass word number among the input data is sent. The telephone number corresponding to the input abbreviated dial number in the area corresponding to the coincident registration pass word number is read from the RAM 17 and the readout telephone number is sent to a trunk line accommodation circuit LC 11 via the I/O INF 15. The LC 11 converts the telephone number into a dial signal and sends it to a trunk line 5.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a button telephone device.

[Conventional technology]

Conventionally, in this type of button telephone device, the speed dial service is provided by registering a regular telephone number in a one-to-one correspondence with a preset speed dial number in the memory circuit of each button telephone. You can freely utilize that speed dial for units.

[Problem that the invention seeks to solve]

In the conventional button telephone device described above, speed dial numbers are registered for each button telephone, so for example, if you personally register a speed dial number on a particular button telephone, you can transfer the speed dial number to another button telephone. The disadvantage is that it cannot be used from anywhere.

[Means for solving problems]

The button telephone device of the present invention includes a plurality of button telephones and a key telephone main device that is connected to each of the plurality of button telephones via a line and also connected to a plurality of office lines. The telephone main device includes a central office line circuit that interfaces with the central office line, a personal identification number predetermined for each subscriber of the plurality of button telephones, a plurality of speed dial numbers corresponding to the personal identification number, and a plurality of speed dial numbers. a storage means in which numbers and telephone numbers in one-to-one correspondence are registered in advance; If the verification results in a match, the system reads out the telephone number that corresponds one-to-one with the speed-dial number that matches the input speed-dial number from the area of the matched PIN and converts it into a dial signal. and control means for controlling the office line circuit to convert the dial signal and send the dial signal to the office line.

〔Example〕

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.

In FIG. 1, the button telephone device of this embodiment includes a plurality of button telephones (hereinafter referred to as T) 24. -2, (an integer of n≧-1) and T2, + -2n, respectively, are connected to each other via a voice line 3 and a data line 4, respectively.

The button telephone main device 1 is a central office line accommodation circuit (hereinafter referred to as LC) that connects to a plurality of central office lines 5 and sends dial signals to the central office lines 5.
11, an audio interface circuit (hereinafter referred to as VINF) 13 that interfaces to the audio circuit 3, a data interface circuit (hereinafter referred to as DINF) 14 that interfaces to the data line, and the audio line 3 through VINF 13 and the LCII. A switch circuit (hereinafter referred to as SW) 12 that performs an exchange connection between the office line 5 and the voice line 3, an input/output interface circuit (hereinafter referred to as 110INF) 15 that interfaces with the LCII, 5W12 and DINF14, and a program are stored. RO, M2
S and T21. A RAM 17 in which the PIN number of each subscriber of 2fi, a plurality of speed dial numbers corresponding to this PIN number, and a telephone number corresponding one-to-one with this speed dial number are registered in advance, and programs from the ROM 18 and R
The central control circuit (hereinafter referred to as CPU) 16 controls the LCII, 5W12, and DINF14 via the I10INF15 based on the data from the AM17.

Next, the operation of this embodiment will be explained.

In advance, T28. ~2n subscriber AI, ~
It is assumed that the personal identification number, speed dial number, and telephone number corresponding to this speed dial number have already been registered.

First, for example, subscriber Al normally makes a call using T21, but T2. When making a call using speed dial, after off-hook T2n,
The user inputs the corresponding speed dial number for the PIN code No. 1 and the telephone number of the person with whom he/she wishes to talk using the dial button of T2n according to a predetermined procedure.

In the button telephone main device 1, T2. The DINF 14 receives input data from the data line 4, and transmits this input data to the CPU 16 via the l10INF15.

When the CPU 16 decodes this input data and determines that it is a request for speed dialing, it sends the PIN registered in the RAM 17 that matches the input PIN from this input data, and uses the matching registered PIN. The phone number corresponding to the input speed dial number in the corresponding area is stored in RAM17.
, and sends the read telephone number to LCll via l10INF15. LCll converts this telephone number into a dial signal and sends it to the central office line 5.

〔Effect of the invention〕

As explained above, the present invention registers a PIN number for each subscriber tone and stores the speed dial number for each subscriber in the storage means of the key telephone main device, so that the subscriber can input his/her PIN number from any key telephone. The effect is that you can use your own speed dial number by entering the number.
