Abstract

PURPOSE:To accommodate a telephone set having direct function button to an exchange by providing a corresponding memory between a function button and a telephone number and a corresponding memory between the telephone number and the allocated position of a telephone set using its number to a private branch of exchange or the like. CONSTITUTION:An individual telephone number is allocated to each function button of the telephone set 5 having function button and its number is stored in an ROM memory 11. When a telephone number assigned to the telephone set 5 is dialed from an optional telephone set, a processore 9 instructs the incoming display to the telephone set 5 via a signal transmission/receiving circuit 7. When the response is operated, the processor 9 sets the allocated position of the responded telephone set to a memory 12, and drives a drive circuit 8 so as to operate a channel switch 6, thereby allowing the connection with the calling telephone set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a telephone number changing system, and more particularly to a telephone number changing system in which the same functions as a button telephone device are added to an exchange.

[Prior art]

2. Description of the Related Art Conventionally, there has been a button telephone device as a device that allows a single telephone to select and switch to any number from among a plurality of telephone numbers by operating a button or the like.

FIG. 1 is a connection diagram of a conventional key telephone device.

In FIG. 1, ``■'' is an exchange to which a button telephone device is connected, that is, a subscriber exchange. Reference numeral 2 is the main device of the key telephone device, which includes a circuit for communicating with the subscriber line, a circuit for communicating between the key telephones, and a circuit for receiving calls to each dedicated extension telephone, when the subscriber line is busy, It has a built-in common control circuit that displays hold status with rung or sound. 3 is a dedicated extension telephone, which has a button for connecting to the subscriber's line when answering or making an incoming call, and displays an incoming call, indicates that the subscriber's line is in use, and temporarily holds the subscriber's winnings. A lamp, buzzer, speaker, etc. is incorporated to identify the device. Cow is a regular telephone connected to exchange l.

The exchange 1 is connected to a general telephone 4 or an inter-office trunk line Lm (L
Translates the telephone number sent via subscriber line DNi (any one of DN1 to DNj) when the number is assigned to a key telephone device. Display incoming calls on the book). The button telephone main device 2 detects an incoming call, notifies the dedicated internal 11s telephone 3, and by pressing the line selection button on the dedicated extension telephone 3, establishes a communication path between the subscriber line and the subscriber's line where the call was received. Set.

In this way, unlike a private branch exchange (PBX), the button telephone device has all subscriber lines extending to the dedicated extension telephone 3, and by displaying the subscriber line status with lamps, the user can Connect to the subscriber line by pressing the button.

By the way, the signal types sent from the exchange 1 to the subscriber line DN1 are a subset of the signal types exchanged with other exchanges through the interoffice trunk line Lm. In other words, the types of signals between exchanges include selection signals such as dial pulse signals and multi-frequency code signals that indicate the number of the called party, monitoring signals that indicate activation, response, disconnection, blockage, etc., and signals that indicate exchange connection to terminals. There are audible signals such as a dial tone, a ring tone, and a busy tone indicating the progress state, and one or two of these signals are sent to the terminal. Therefore, since the button telephone device can only send signals of the same type as the terminal, it is subject to restrictions on service specifications. For example, if subscriber line DN is on hold on dedicated extension telephone 3 and the other party disconnects the connected line, the end-of-call signal that arrives at interoffice trunk line Lm will not be sent to subscriber line DNi. , the subscriber line is put on hold. Further, since the button telephone device requires the main device 2 in addition to the dedicated extension telephone 3, it is disadvantageous in terms of cost and installation space.

[Purpose of the invention]

The purpose of the present invention is to eliminate such conventional drawbacks, connect the extension telephone of the button telephone device directly to the exchange, and consolidate the functions of the main device in the exchange, thereby reducing the cost and space required for the main device. We would like to provide a phone number change method that allows users to change their phone number.

[Summary of the invention]

In order to achieve the above object, the telephone number change method of the present invention uses telephones equipped with function buttons in addition to dial buttons in private branch exchanges, office collective exchanges, or central office exchanges that connect inter-office trunk lines. a first memory for directly accommodating and storing telephone numbers corresponding to function buttons of the telephone;
A second memory that stores information for identifying the telephone that is using the telephone number corresponding to the telephone number is thrown, and the stored contents of the second memory are changed by operating the function buttons of each telephone. , is characterized by changing the correspondence between telephones and telephone numbers.

[Embodiments of the invention]

FIG. 2 is a functional block diagram of a telephone number change system showing an embodiment of the present invention.

In Fig. 2, the cow is a general telephone, 5 is a telephone equipped with function buttons, such as transfer, speed dial, answering machine registration, etc., 6 is a call path switch, and 7 is a telephone with function buttons for transmitting and receiving signals. 8 is a driving circuit for a communication path switch, 9 is a processor, 10 is a memory containing a control program, 11 is a first memory that stores a telephone number for each function button of a telephone equipped with function buttons, and 12 is a telephone number. This is a second memory that stores, for each telephone number, the housing position of the telephone with function buttons that is making a call using that telephone number.

In FIG. 2, the first memory 11 and the second memory 12 play an important role, and the first memory 11 is used to register arbitrary phone numbers that are partially or completely duplicated for each function button. ROM is usually used because it is a storage device and once registered, there are almost no changes. In addition, the second memory 12 temporarily stores the currently used telephone for each telephone number.In order to prevent two or more duplicate telephone numbers from being used at the same time, the contents are constantly updated from the processor. Usually RA
M is used.

Normally, a plurality of telephones 5 with function buttons are connected to the call path switch 6, but only one is shown to represent them.

The telephone 5 has, for example, a transfer button as a function button.
Assuming that there are three buttons, a speed dial button and an answering machine registration button, each of these function buttons has (48) 1121
．． (48)1232. Separate telephone numbers such as (48) 5823 can be assigned, and these same numbers can also be assigned to other feature buttons on other telephones. Let this telephone number be N1 (N1 to Nj).

When one of the telephone numbers Ni assigned to the functional telephone 5 in FIG. 2 is dialed from any telephone housed in the local exchange or another exchange, this dialed number is stored in a register, etc. (not shown). and is notified to the processor 9.

The processor 9 refers to the entire area of the memory 11 and stores the telephone number N.
The telephone 5 to which I is set and its function button positions are known. In this case, since there may be two or more telephones set with Ni, all of them are notified of the incoming call. That is, the processor 9 instructs the telephones 5 to display an incoming call via the signal transmitting/receiving circuit 7. When any one of the telephones displaying an incoming call presses the function button and performs a response operation, the processor 9 is notified via the signal transmitting/receiving circuit 7, and the processor 9 responds to the second memory 12. At the same time, the drive circuit δ is driven to operate the communication path switch 6, thereby connecting the telephone to the originating telephone or the interoffice relay line. Even if there is a subsequent response operation for the same telephone number Ni from another telephone, the processor 9
By referring to memory 12, there is a telephone that has already responded and is connected, so the response is invalidated. Special audible signals can also be sent to the phone when the answer is disabled (answer disabled tone, busy tone, etc.). Further, when the telephone 5 having the telephone number Ni is on a call and another caller receives a call to the same telephone number N1, the processor 9 refers to the second memory 12 and determines that the telephone number Ni has already been called by the telephone. It learns that the phone is being used and sends a busy tone to the other party (caller). At the end of the call, the second memory 1
According to the contents of 2, the telephone 5 and the communication path switch 6 are opened, and the contents of the second memory 12 are cleared.

Next, the outgoing connection from the telephone 5 will be described.

When one of the function buttons of the telephone 50 is pressed to perform an oscillation operation, the processor 9 is notified of the call via the signal transmitting/receiving circuit 7.
1 to know the telephone number Nll that the telephone convex is to use, then refer to the second memory 12 and read the contents with the telephone number Ni as an index. In this case, if the telephone number Ni is in use, the read content indicates the accommodation position of another telephone, so the outgoing call is disabled. Further, when nothing is set in the second memory 12, the telephone number N1 is not in use, so the call is accepted and the storage position of the tortoise phone convex is set in the second memory 12. At the same time, by transmitting a dial tone to the telephone 5, the switch 6 is activated in order to form a communication path to the nine destinations of the telephone number dialed by the telephone 5. When the other party answers, the call state is entered, but when a call to the telephone number JIC is received from another caller in this state, the processor 9 refers to the second memory 12 and determines that this number Ni is in use. and connect the busy tone.

〔Effect of the invention〕

As explained above, according to the present invention, by providing a memory for correspondence between a function button and a telephone number, and a memory for correspondence between the telephone number and the housing position of the telephone using the number, it is possible to directly press the function button. Since the attached telephone set can be housed in the switchboard, it is possible to provide the service as a button telephone while retaining the rich services of a business group switchboard, etc. Moreover, since the main equipment is not required, costs can be reduced. There is an advantage of space reduction.
