Abstract

PURPOSE:To improve the service function without increasing the memory capacity by reading a telephone number instructed by an abbreviation dial registration area of other telephone set based on the key operation so as to send a dial signal to a trunk line. CONSTITUTION:When a telephone set 21 designates a trunk line 11 and makes dialing, a control circuit 70 discriminates a key operation signal and selects a common area in each area of a memory 80 in response to the result of discrimination, e.g., in the abbreviation dial transmission control mode and an individual area corresponding to the telephone set 21. Then the abbreviated dial number by the dial key operation is inputted and the address designated by the abbreviated dial number in the common area or the individual area of the memory 80 is accessed to read a telephone number. Then the control circuit 70 drives a transmission circuit 60 to send the dial signal corresponding to the telephone number to the trunk line 11.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to an improvement in a telephone device having a speed dialing function and comprising an exchange control device and a plurality of telephones.

[Technical background of the invention]

A known telephone device of this type is a button telephone device. This button telephone device generally accommodates a plurality of telephone lines in all of the telephones, each having more than ten telephone lines, and selects a line, puts it on hold, etc. by operating the buttons attached to each telephone Isofune.
This system allows for busy display, selective calling between telephones, mutual conversation, etc. It has a relatively simple configuration and allows a small number of central office lines to be shared by many telephones, so it is often used in offices, etc. There is.

By the way, recently some key telephone devices have been provided with a speed dial transmission function. Conventionally, this type of button telephone device has a memory for abbreviated dialing, for example, where a plurality of telephones are connected to each other via an extension line.
7.Register the other party's phone number 1 from the telephone side when dialing 61, part 1.7. Select a speed dial memory by operating a specific key among the keys, or by pressing the By reading the telephone number, a dial signal corresponding to the telephone number is sent out. Therefore, it is very convenient to register the telephone number of the person you frequently call on each telephone in advance, since you can easily call the person using a few digits.

[Problems with background technology]

However, generally, a fixed amount of the registration area of the speed dial memory is allocated to each telephone Isofune, and therefore there is an upper limit to the number of registrations. For example, as shown in Figure 6, the registration area of the speed dial memory is divided into a common area A (addresses 00-79) that can be commonly used by each telephone, and an individual area B (addresses 80-99). The individual areas are roughly evenly divided into 81 to 13n for each telephone. Therefore, in this case, the only registered areas that each telephone can use are the common area 8 and the individual areas 81 to 3n assigned to itself, and the maximum number of registered areas is fixed at 100. For this reason, even if an arbitrary telephone set wanted to register 100 or more speed dials, it would not be able to handle this, which would be very inconvenient for some users. In addition, in order to increase the number of registrations, it is possible to increase the capacity of the speed dial memory, but this makes the device expensive, which is not desirable.

[Purpose of the invention]

An object of the present invention is to easily meet a request for an increase in the number of registered speed dial numbers without increasing the number of customers in a speed dial memory, thereby providing a button telephone device that is inexpensive and has high service functions.

(Summary of the Invention) In order to achieve the above object, the present invention provides a telephone with a switching key, and an exchange control device that includes key operation detection means for detecting the operation of the switching key, and speed dial transmission control means. and when the key operation detection means detects an operation of the switching key, the speed dial transmission control means reads the designated telephone number from the speed dial registration area of another telephone based on the subsequent operation of a predetermined key. The telephone number is read and a dial signal is sent to the central office line based on this telephone number.

[Embodiments of the invention]

FIG. 1 shows the configuration of a telephone device in an embodiment of the present invention. This device is a button telephone device and has two
Book station! ! ! 11. A main device 10 as an exchange control device connected to
Multiple (n) telephones 121 to 2n connected through the day
It consists of

These telephones 21 to 2n each have a selection button, a call display lamp, a hold button, etc. provided correspondingly to each telephone, as well as a push-button type dial key 90 as shown in FIG.
and a registration area switching key 100. This registration area switching key 100 is operated when selecting an individual area for a telephone other than the user's own among the individual areas for speed dial number registration set for each of the telephones 21 to 2n.

The main device 10 includes a selection circuit 30 and office line circuits 51, 52 provided for each office line 11, 12 and each extension 31 to 3n.
It is composed of an extension circuit 41.4n, a dial sending circuit 60 that generates a dial signal, a control circuit 70, and a speed dial memory 80. Among these, the speed dial memory 80 is for registering speed dial numbers, and its configuration is, for example, as shown in FIG.
1 to Br'l. - the force control circuit 70 is
For example, it is equipped with a microcomputer as a control unit, and is capable of controlling general button telephone equipment such as selective connection control between each telephone set 21 to 2n, call display control, connection control to central office lines 11 and 12, etc. , as shown in FIG. 2, an operation key discrimination means 70a and a first speed dial transmission control means 70b.
and a second speed dial transmission control means 70c. First, the operation key determining means 70a determines that the key operated on the telephones v121 to 2n after acquiring the central office line is the dial key 90.
This is for determining whether it is a specific key (X key) or the registration area switching key 100. Further, when the operation key discriminating means 70a detects that the key in the dial key 90 has been operated, the first speed dial transmission control means 70b transmits information to the common area A and the telephone that operated this key. The system selects corresponding country areas and controls the transmission of dial signals according to the telephone numbers registered in these areas. Furthermore, the second speed dial transmission control mechanism 70c is subsequently designated by the key number of the dial key 90 when the operation key determination means 70a detects that the registration area switching key 100 has been operated. Individual areas 81-Bn corresponding to telephones 21-2n are selected, and transmission of dial signals is controlled in accordance with the telephone numbers registered in these individual areas.

Next, the control circuit 7 controls the operation of the device configured as described above.
This will be explained according to the control procedure of No. 0. In addition, dial key 90
It is assumed that the numeric keypad is associated with 12n for each telephone set 21, for example, as shown in FIG. 3, for specifying the registration area.

In the standby state, the control circuit 70 monitors the occurrence of incoming calls and outgoing calls in steps 5a and 5b, as shown in FIG. 5(a). If an incoming call occurs, the process moves to step 5C, where predetermined call incoming control is performed.

Now, when the telephone 21 performs a call operation by specifying the central office line 11 in the above-mentioned standby state, the control circuit 70 first captures the central office line 11 in step 5d, and then inputs a key operation signal in step 5e. and step 5f~5
This key operation signal is determined in step h. That is, first, in step 5f, it is determined whether or not it is a key, then in step 59, it is determined whether or not it is a registration area switching key 100, and finally, in step 5h, it is determined whether or not the dial key 90 is a key. It is determined whether or not it is the numeric keypad inside.

Now, for example, if the operator of the telephone 21 immediately operates the numeric keypad, the control circuit 70 determines that the mode is not the speed dial transmission mode but the normal transmission mode and moves to step 51? j, and here, the dial sending circuit 6 is activated in accordance with the key number that is subsequently inputted from the dial key 90.
A dial signal is generated from 0 and sent to the central office line 11.

On the other hand, if the operator of the telephone 21 first operates the
The process moves to step 5j shown in FIG. 5, and in step 5j, the common area A and the individual area B1 corresponding to the telephone line 21 are selected from among the areas of the speed dial memory 80.

Then, in step 5, the speed dial number specified by the operation of the dial key 90 is inputted, and the correctness of the input is confirmed in step 5λ. The address specified by the speed dial number in B1 is accessed and the telephone number is read out. For example, if the operator inputs speed dial numbers "5" and "4", the operator accesses address 54 in common area A and reads out the telephone number registered at this address. Also, operation I-
If the user inputs 8" and 0" as shown in FIG. 4 (a), the control circuit 70 accesses address 80 of individual area B1 and reads out the telephone number registered at this address. .Then, when the telephone number is sent one after another, the control circuit 70 moves to step 51, where it drives the dial sending circuit 60 to send out a dialing signal corresponding to the above-mentioned telephone number to the central office line 11, thus normally A central office line call is made by sending a speed dial.

By the way, when the office line is in trouble, the operator of the telephone 21 first operates the registration area switching key 100, as shown in FIG. 4(b), and then presses "2" on the dial key 90.
Assuming that the key is operated, the 1111 fault circuit 70 detects the operation of the registration area switching key = ioo in step 5g and determines that it is the second shortened dial N full transmission control mode, and then moves to the step 5n1X key number Enter key 2', check whether the key is correct or not in step 50, and then proceed to step 5.
In step 5q, the telephone 2"' corresponding to the "2" key is determined. In step 5q, the individual area B2 of the speed dial memory 80 corresponding to this telephone 22 is selected.

In this state, the operator operates the dial key 90 to enter the speed dial number "8", for example, as shown in FIG. 4(b).
When 1Z1''O'' is specified, the control circuit 70 inputs this speed dial number in step 5, confirms whether the key is pressed correctly in step 5, and then moves to step 5m where 80 of individual area B2 is input. Access the address and read out the telephone number registered at this address. Then, in step 51, the dial sending circuit 60 is driven to generate a dial signal corresponding to the above-mentioned telephone number, and the central office line 11 is
send to. Thus, a speed dial is sent using the separate area of the other telephone.

In this way, with this embodiment, speed dial transmission can be performed by selecting the individual area of another telephone, so even if the individual area of the own telephone is full, the individual area of the other telephone can be sent. If there is a vacant address in the area, a telephone number can be registered at this vacant address and speed dial transmission can be performed.

Therefore, the registration area can be increased with a simple operation without increasing the capacity of the speed dial memory 80, and an inexpensive device with high service functions can be provided.

Note that the present invention is not limited to the above embodiments. For example, in the above embodiment, each of the telephones 21 to 2n is associated with the numeric keypad of the dial key 90 on a one-to-one basis, and individual areas of other telephones are designated by operating the numeric keypad. If there are 11 or more telephones, each telephone may be represented by two digits on the numeric keypad. Furthermore, in the embodiment described above, each telephone can unconditionally select the individual areas of all other telephones, but if necessary, it is possible to set conditions for individual areas for each telephone to prevent selection from other telephones. Alternatively, the configuration may be such that only specific telephones can be selected. In addition, the control procedure and control contents of the control circuit, the configuration of the registration area switching key, the dial key, etc. can be modified in various ways without departing from the gist of the present invention.
