Abstract

PURPOSE:To identify a caller by storing an incoming tone data representing kinds of an incoming tone together with a caller telephone number, reading a relevant incoming tone data when a coincident telephone number exists in the case of the arrival of a call and sending the data to a key telephone set. CONSTITUTION:When a call comes to an ISDN line, a CPU 14 analyzes call setting information sent from the ISDN line, a caller number A is extracted from the call setting information to read a telephone number in a block (k) of an incoming tone memory 16 and the read telephone number is compared with the caller number A. When they are equal to each other, the incoming tone data in the memory block (k) is read. Through the processing above, when a call comes from the ISDN line, a key telephone set rings an incoming tone corresponding to the caller telephone number according to the caller telephone number sent from the ISDN line.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic button telephone device, and in particular, the main device has an I/O button.
The present invention relates to an electronic button telephone device that interfaces the S/T point of an SDN line.

[Conventional technology]

Conventionally, this type of electronic button telephone device has been configured to display the telephone number of the calling party on a character display included in the button telephone when a call is received from an ISDN line.

[Problem to be solved by the invention]

The above-mentioned conventional electronic button telephone device is configured to display the caller's phone number on the character display included in the button telephone when a call is received from the ISDN line. If a call is received on a telephone that is not equipped with a button, the disadvantage is that the caller cannot be identified before answering.

[Means to solve the problem]

The electronic button telephone device of the present invention has three ISDN lines.
In an electronic button telephone device having a main device that houses a button telephone equipped with a 77-point interface and a ring tone sounding means that sounds multiple types of ring tones,
The main device has a storage unit capable of storing ringtone data indicating the type of the ringtone together with the telephone number of the calling party,
When a call is received from the ISDN line, the ISDN
The calling party's phone number in the call setting information sent from the line side is compared with the phone number stored in the storage unit, and if there is a matching phone number, the corresponding ringtone data area and a ringtone data sending means for sending the ringtone data of the area read by the readout means to the button telephone set.

〔Example〕

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

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

In FIG. 1, the present embodiment includes a key telephone 11 and a main device 13, and the key telephone 11 receives and receives ring tone data indicating the type of ring tone from the main device 13, thereby making a corresponding response. It is configured so that it can play a ringtone.

The main device 13 includes a button telephone interface 12 that interfaces with the button telephone fill, a central control unit (hereinafter referred to as CPU) 14 that controls the entire button telephone device of this embodiment, and a main device 13 that is necessary for controlling the main device 13. A RAM 15 in which information is stored, a ringtone memory 16 specially provided in this embodiment in the RAM 15, and three ISDN lines.
It has a line interface 17 for accommodating a 77-point interface.

FIG. 2 is a diagram showing an example of the configuration of the ringtone memory in the present embodiment of FIG. 1.

In FIG. 2, the ring tone memory 16 is divided into m+1 blocks, each of which stores the caller's telephone number and ring tone data corresponding to the telephone number that should be made to ring when a key telephone receives a call. There is. Incidentally, the m+1th block stores ringtone data that is to be sounded when there is an incoming call and the caller's telephone number is not registered in the ringtone memory 16.

FIG. 3 is a flowchart showing an example of the processing of the CPU when an incoming call is received in this embodiment.

Next, the operation of this embodiment will be explained using FIG. 1, FIG. 2, and FIG. 3.

If there is an incoming call on the ISDN line, the information is notified to the CPU 14 via the line interface 17. The CPU 14 starts processing according to the flowchart shown in FIG. First, the "call setting" information sent from the ISDN line is analyzed (S31), and the presence or absence of the calling party's telephone number (hereinafter referred to as calling number) is determined (S32).

If there is no calling party number, it is unknown who the calling party is, so the ring tone data stored in the m+1th block of the ring tone memory 16 is read out (S40). If there is a calling number, extract the calling number A from "Call settings" (833), then set the initial value 1 to the variable k used for calling in the ringtone memory 16 (S34), and The number m of 16 blocks is compared with the variable k (S35). Note that k is a variable for counting the blocks in the name memory, and m is the number of blocks in the name memory.

If the variable k is larger than m, the ringtone memory 16
This means that the reading of the ringtone memory 1 has been completed.
6, it is determined that there is no corresponding telephone number, so the ring tone data of block m+1 of the ring tone memory 16 is read out (S40).

If the variable k is smaller than m, the telephone number in block k of the ring tone memory 16 is read out (537), and the read telephone number is compared with the calling number A (S38). if,
If they are not equal, 1 is added to the variable k in order to read the next memory block (536), and the process of S35 is performed again. If they are equal, the ring tone data in memory block k is read (S39).

Next, it is checked whether there is a key telephone that displays an incoming call (S41). If it exists, the read ring tone data is sent to the key telephone.542) The process ends. If there is no button telephone, the process ends.

Through the above processing, in this embodiment, when there is an incoming call from the ISDN line, the key telephone sets a ring tone corresponding to the caller's phone number according to the caller's phone number sent from the ISDN line. It becomes possible to do so.

〔Effect of the invention〕

As explained above, the present invention has a storage section in the main device that can store ringtone data indicating the type of ringtone as well as the telephone number of the calling party, and when a call is received from an ISDN line, Compares the calling party's phone number in the call setting information sent from the SDN line with the phone number stored in the storage unit, and if there is a matching phone number, reads the corresponding ringtone data area. By having a readout means and a ringtone data sending means for sending the ringtone data of the area read out by the readout means to the button telephone, ■When there is an incoming call from the SDN line, the button with a character display Even if it is not a telephone, if you have a button phone that can play multiple ringtones, you can identify the caller by the ringtone, so for example, you can register only the phone number of a particularly important person in the ringtone memory. This has the effect of making it possible to distinguish by having a special ringtone sound on the key telephone only when there is an incoming call from an important party.
