Abstract

PURPOSE:To facilitate a variable abbreviated dial registration by providing a dial number storage circuit storing a dial number dialed by a telephone set and writing the dial number dialed the preceding time into a variable abbreviation dial registration area. CONSTITUTION:A dialed number from a telephone set 6 is received by all register circuits 4 and a central processing unit 2 sends accommodation location information of the telephone set 6 connecting to the register circuit 4 and dial number information to a main storage device 3. When the telephone set 6 dials a predetermined special number and the central processing unit 2 recognizes the number to be a predetermined special number, the main storage device 3 reads out the outgoing number dialed the preceding time based on the accommodated location information and the central processing unit 2 recognizes the abbreviated number received successively, the main storage device 3 decides the storage location from the abbreviated number information and writes the outgoing number dialed preceedingly. Thus, the variable abbreviation dial registration is attained with a simple procedure.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a storage program type electronic exchange equipped with a variable abbreviated dial registration function, and in particular, to a storage program type electronic exchange equipped with a variable abbreviated dial registration function, and in particular, a variable abbreviated dial registration that can be performed by a simple procedure from a housed telephone. A store-programmed electronic switch that can be used.

[Prior Art] Variable abbreviated dial registration in a conventional storage programmable electronic exchange involves dialing a variable abbreviation registration special number and an abbreviated number from a telephone housed in the storage programmable electronic exchange, and then dialing a regular number. I dialed it.

[Problems to be solved] In the conventional storage program type electronic switching equipment described above, when registering variable abbreviated dialing, it is necessary to dial the variable abbreviated dialing registration special number and the abbreviated number followed by the regular number, making it difficult to make long-distance calls. If the regular number is long, such as a number or international dialing number, it takes time to dial, and it is also annoying to have to dial while looking at a memo. The problem was that updates were slow and the convenience of the speed dial function itself tended to diminish.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a storage program type electronic exchange that allows variable abbreviated dial registration through a simple procedure from a housed telephone.

[Means for Solving the Problems] In order to achieve the above object, the storage program type electronic exchange of the present invention includes a call route switch, and a dialed number storage circuit that stores dialed numbers dialed by a telephone connected to the call route switch. , a main storage device that stores speed dial information, and a central processing unit that controls the communication path switch and the main storage device.

When the speed dial registration special number and the speed dial number are input from the telephone via the call path switch, the central processing unit converts the dial digits stored in the dial numeral storage section into the dial digits of the speed dial number. It is registered in the main storage device as .

That is, the dialed digits dialed last time are stored, and when a predetermined registered special number is dialed, the dialed digits are read out, and the dialed digits are used for variable speed dialing for each abbreviated number dialed next. Registered in main storage.

[Example] Hereinafter, the present invention will be explained in detail based on the drawings.

1 and 2 are block diagrams showing a relay system of a storage program type electronic exchange according to an embodiment of the present invention, and FIGS. 3 and 4 are main memories shown in the storage program type electronic exchange of FIGS. 1 and 2. FIG. 3 is a memory configuration diagram of the device.

In Figures 1 and 2, 1 is a communication path switch (SW)
, 2 is the central processing unit (CC), 3 is the main memory (MM)
, 4 is a register circuit (ORT), 5 is a central office trunk circuit (COT), and 6 is a telephone set.

In FIG. 1, the telephone 6 is in a central line or international outgoing state, and connects to the register circuit 4 via the call path switch l.
It is connected to the central office line trunk circuit 5.

At this time, all the numbers dialed from the telephone 816 are received by the register circuit 4, and the received dialed numbers are
It is sent from the register circuit 4 to the central processing unit 2 (broken line 7).
). Then, the central processing unit 2 sends the accommodation position information and dial number information of the telephone 6 connected to the register circuit 4 to the main storage device 3.

On the other hand, the main storage device 3 determines the storage location from the storage location information sent from the central processing unit 2, and writes the dial number information.

Note that FIG. 3 shows the state of the memory that stores this dialed number information, and is provided with received number information for a maximum of 24 digits for all storage positions.

Next, in FIG. 2, the telephone 6 is in a state where the above-mentioned connection has been completed and a new call has been made, and the telephone 6 is connected to the register circuit 4 via the communication path switch l.

Then, the telephone 6 dials a predetermined special number, and the number received from the register circuit 4 is sent to the central processing unit 2.
(dashed line 8).

Now, when the central processing unit 2 recognizes that the number received by the register circuit 4 is a predetermined special number, it sends the accommodation position information of the telephone 6 connected to the register circuit 4 to the main memory 3. do. The main storage device 3 also reads out the last dialed calling number (the state shown in FIG. 1) based on the storage location information. Further, the central processing unit 2 recognizes the abbreviated numbers successively received by the register circuit 4, and sends the previously read calling number and abbreviated number to the main storage device 3. Then, the main storage device 3 determines a storage location from the abbreviated number information and writes the last dialed calling number.

Note that FIG. 4 shows a memory configuration for storing abbreviated number information, and similarly to FIG. 3, up to 24 digits of dialed number information can be
It is provided for all abbreviated numbers.

In this way, the storage program type electronic exchange of this embodiment is
A dialed digit storage circuit that stores the last dialed digits is connected to the call route switch, and this dialed digit storage circuit is controlled to store and read out the dialed digits, and when a predetermined registered special number is dialed, , the dial numbers read from the dial number storage circuit are registered in the main memory for variable abbreviated dialing.

[Effects of the Invention] As explained above, the present invention includes a dial digit storage circuit that stores the dial digits dialed by the telephone, so that the previously dialed digits can be written into the variable speed dial registration area by a simple operation. As a result, it is possible to provide a storage program type electronic exchange that not only facilitates the registration operation but also enhances the convenience of the variable abbreviated dialing service and promotes its use.
