JPS60100863A - Abbreviated dialing system in direct-in dial system - Google Patents

Abstract

PURPOSE:To dial-in effectively an opposite party without dialing a number with several digits at the time of connecting of a direct-in dial by replacing an opposite main wire number and an extension number to be called with abbreviated dialing. CONSTITUTION:A subscriber A to a abbreviated dialing system hooks off a telephone set, and a central controller 1 detects the hooking off by a subscriber circuit 2, which is connected to an outgoing register 4 through an automatic exchange 3. After the subscriber A has heard an outgoing sound, he dials a direct- in dial (DID) abbreviated dial number. The register 4 counts the specific number by the abbreviated dialing, and transmits it to a specific number discrimination device 5. The device 5 discriminates the specific number of an abbreviated dialing set, and the discriminated result is transmitted to the control ler 1. Under the control of the controller 1, an abbreviated number, a curve number and an opposite extension number from the subscriber A are accumulated in a DID abbreviated number accumulating device 6. Therefore the subscriber can effectively dial-in an opposite party.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical field to which the invention pertains The present invention relates to a speed dialing function in an automatic private branch exchange.

Φ) Prior art In the past, abbreviated dialing systems using only the office line number or only the extension number have been put into practical use in automatic private branch exchanges. However, when connecting with Direct In-Dial (hereinafter abbreviated as DID), even if you dial the office line number using speed dial, you have to separately dial the extension number of the other party, and the speed dial function is not sufficient. There was a drawback that it was not fully utilized.

(C) Object of the Invention The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology.Therefore, the object of the present invention is to convert the office line number and extension number to bare KL, and furthermore to A storage device is installed to store the numbers in correspondence.

An object of the present invention is to provide a new automatic private branch exchange that can easily establish a DID connection through abbreviated dialing operations.

(d) Structure of the Invention In order to achieve the above objects, the speed dialing system according to the present invention provides a method for dialing the number of destinations in an automatic private branch exchange that is intended to be connected to an automatic private branch exchange that employs a direct in-dial system. Assuming the previous office line number and extension number as bare,
Furthermore, a storage device stores the pairs and speed dial numbers in correspondence with each other.

A special number identification device for identifying special numbers and speed dial numbers for setting and resetting speed dials, and a dialing signal sending device that sends the destination office line number and extension number as dial signals to the destination private branch exchange. and p DI with - number of speed dial operations
It is characterized by the following characteristics:

(e) Embodiment of the Invention Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram illustrating the setting of a DID speed dial number by a subscribed senior citizen in accordance with the present invention.

When the subscriber hooks off the telephone, the central controller 1 receives a shift-off signal from the subscriber circuit 2 and connects the subscriber circuit 2 to the calling register 4 via the automatic switching device 3. After hearing the dial tone, subscriber A dials a special number to set the DID speed dial number. When the special number dial signal is counted by the nuclear transmission register 4 and transferred as number information to the special number identification device 5,
The special number identification device 5 identifies the special number as a DID speed dial set.

The identification result is transferred to the central control device 1. Based on the identification result, the central control device 1 becomes ready to accept the DID speed dial set. From now on, the shortened number 1 station Senkou from the elderly who joined,
The extension number of the other party is determined by the control of the central controller 1j) DI
D is stored in the abbreviated number storage device 6.

FIG. 2 is a block diagram illustrating a subscriber elderly person making a call to a central office line using DID abbreviated dialing according to the present invention.

The abbreviated number dialed by nuclear subscriber A is 1 dialing register 4
At the same time, the special number identification device 5 identifies the number as a speed dial. The central control device 1 receives the identification result from the special number identification device 5, determines whether or not the corresponding number information is stored in the DID abbreviated number storage device 6, and if it is stored, the corresponding station At the same time as transferring the line number and destination extension number information to the dial signal transmitting device 7, the dial/l/signal transmitting device 7 and the office line trunk 8 are connected via the automatic switching device 3. .

The dial signal sending device 7 sends the transferred office line number and destination extension number as a dial signal to the office line and the destination private branch exchange CO via the office line trunk 8. In this way, the subscriber A desired connection is terminated.

If you still want to reset the DID speed dial, dial the special number and speed dial number for resetting, even if the contents stored in the DID speed dial storage device 6 are erased under the control of the central controller l ( f) Effects of the Invention As explained above, the present invention has the effect of eliminating the need to dial many digits when connecting to a DID by replacing the office line number and extension number of the person you are trying to call with speed dialing. There is.
