Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a key telephone apparatus.

[0002]

2. Description of the Related Art With the spread of telephones, in a key telephone apparatus, each person often occupies a telephone to which an extension number is assigned. On the other hand, in places where the frequency of calls is not too high or in small places, one telephone is often shared by a plurality of persons.

[0003]

However, conventionally, in a key telephone apparatus in which one telephone is shared by a plurality of persons,
At first, someone answered the call, asked the caller who was in need, and then picked up the person. Therefore, there is a problem that it is necessary to spend precious time for the transfer, and it takes time for the caller to talk with the intended person.

[0004] The present invention has been made in view of such a point, and even when a single telephone is shared by a plurality of persons, the person who is on the telephone can directly talk with the caller. It is an object of the present invention to provide a key telephone device that does not require the transfer of another person.

[0005]

One telephone is provided with a plurality of extension numbers, and the tone color of a ring tone is divided for each extension number, and when an individual call arrives, a ring tone is used to indicate to whom.
That is, an extension number table for setting a plurality of extension numbers and a ring tone number table for setting a ring tone are provided for each telephone. By retrieving the extension number dialed at the time of calling an extension from the extension number table where the extension number is set, the incoming telephone and the ring tone number are derived, and this incoming telephone is made to ring with the tone of this ring tone number, and to whom Notify you of an incoming call. As described above, when a single telephone is shared by a plurality of persons, when a call is received, the caller can be notified of the incoming call by a ring tone, and the caller can talk with the intended person because there is no need to relay the call. It doesn't take long.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to solve the above-mentioned problems, a key telephone apparatus of the present invention provides a plurality of extension numbers on one telephone, and sets a ring tone number corresponding to these extension numbers.
It is characterized in that ringtones of different tones corresponding to these ringtone numbers are provided, and means for notifying to whom the call is made is provided by the ringtones of these different tones.

[0007] The means for informing who the call is to by the ring tone of a different tone is the R
An extension number table 41 and a ring tone number table 42 are provided in AM7, and the extension number dialed when an extension is dialed is retrieved from the extension number table 41 to derive an extension port number and a ring tone number, and a button connected to the extension port number The present invention is characterized in that a ring tone of a telephone is caused to sound in a tone color of a ring tone number corresponding to an extension number.

Reference numeral 6 denotes a ROM, 7 denotes a RAM storing an extension number table and a ring tone number table to be described later, 21-1 to n denote key telephones, 22 denotes a communication circuit, 23 denotes a data transmission control circuit, 24 denotes a control circuit, and 25 denotes a control circuit. Is a CPU, 26 is a ROM, 2
Reference numeral 7 denotes a RAM, reference numeral 28 denotes a receiver, reference numeral 29 denotes a speaker, reference numeral 30 denotes a microphone, reference numeral 31 denotes an LED serving as a display unit, and reference numeral 32 denotes keys such as a dial and a function.

FIG. 2 is a diagram showing an extension number table and a ring tone number table used in the key telephone apparatus in one embodiment of the present invention. As shown in the figure, the extension number table 41 and the ring tone number table 42 have the same structure. The extension number dialed at the time of calling the extension is retrieved from the extension number table 41, and the extension port number and the ring tone number are derived. The telephone connected to the derived extension port number is caused to sound a ringtone of the tone of the ringtone number derived in the ringtone number table 42.

For example, if the extension number retrieved from the extension number table 41 is 1-1, the corresponding telephone is the key telephone 21-1 connected to the extension 1 port of the key telephone main unit 1. A ring tone of the tone color of the ring tone number 1-1 sounds from the ring tone number table 42.

FIG. 3 is a flowchart showing the operation of the key telephone apparatus in one embodiment of the present invention. Symbol S
The numerical value following "" indicates a step number. [S1] The presence or absence of an incoming call is monitored. If there is an incoming call, the process proceeds to S2, and if not, the process returns to S1 to continue monitoring. [S2] The extension number of the incoming call is searched from the extension number table 41 in which the extension number is set. [S3] From the extension number table 41, the extension port number and the ring tone number of the destination corresponding to the extension number are obtained. [S4] The telephone connected to the extension port of the corresponding number sounds a ringtone having a tone color corresponding to the determined ringtone number. [S5] The calling party is calling and the called party is receiving a call. [S6] In response to the incoming call response of the extension telephone on the receiving side, the operation shifts to the start of the call.

In the embodiment, in one telephone provided with a plurality of extension numbers, ringtones having different timbres from the speaker 29 are used to identify the extension numbers. Further, displaying the extension number and the name of the person concerned on the LED 31 of the key telephones 21-1 to 21-n further enhances convenience.

[0013]

As described above, the key telephone apparatus of the present invention provides a plurality of extension numbers on one telephone, provides ring tone numbers corresponding to these extension numbers, and assigns these ring tone numbers to these extension numbers. The corresponding ringtones of different tones are provided, and the means for notifying who is calling by these different ringtones are also provided, so that the ringtones of different tones indicate who is calling. The means is provided with an extension number table 41 and a ring tone number table 42 in the RAM 7 of the key telephone main unit 1, and retrieves the extension number dialed at the time of calling an extension from the extension number table 41 to derive the extension port number and the ring tone number. Since the ring tone of the key phone connected to the extension port number sounds in the tone of the ring tone number corresponding to the extension number, it is easy to know who the call is to, And then, yet it is no longer to wait for the caller.
