Abstract

PURPOSE:To attain calling by an abbreviated dial even to an opposite subscriber not set with the abbreviated dial by designating an abbreviated dial code set for other extension subscriber and using it from an extension subscriber making a call. CONSTITUTION:When an extension subscriber telephone set STA hooks off, the telephone set is connected to an outgoing register trunk ORT and a call tone is confirmed. The extension subscriber telephone set STA makes then dialing of X+YYY+ZZ. X is an access number to be accessed to the set abbreviated dial code set for other extension subscriber. A central controller CPU identifies the access to the abbreviated dial code set for other extension subscriber by receiving the information X and transmits allocated position information LEN of the stored extension subscriber telephone set STA and the information X to an adaptor ORTAP added to an outgoing register trunk ORT in case of call tone connection.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an abbreviated dialing system in an automatic telephone exchange.

<Prior art> Conventionally, there have been two types of abbreviated dialing codes in abbreviated dialing connections: one that is common to the system, that is, one that can be used by any extension subscriber, and one that is unique to each extension subscriber.
In the latter case, it cannot be accessed from other extension subscribers other than the one making the call, in other words, the abbreviation code of the desired subscriber is set for other extension subscribers. However, there was a drawback in that an extension subscriber making a call had to dial all the digits to make a connection.

Note that "other extension subscribers" used hereinafter means "an extension subscriber other than the extension subscriber making the call."

<Object of the Invention> The present invention has been made in view of the above-mentioned drawbacks, and its object is to enable dialing from any extension subscriber using an abbreviated dialing code set correspondingly to each extension subscriber. Its purpose is to enable abbreviated dial connections.

<Structure of the Invention> The present invention provides access identification means for accessing an abbreviated dialing code set for other extension subscribers, accommodation location information of an extension subscriber making a 9 call, other extension subscriber numbers, and an abbreviated dialing code. By storing, analyzing and identifying the dial information of the extension subscriber making the call, it is compared with the subscriber number of the other party corresponding to the abbreviated dial code set for other extension subscribers. The present invention is characterized in that the extension subscriber who performs dialing and outgoing calls is connected to the other subscriber.

<Example> Hereinafter, a detailed example of the present invention will be described with reference to the drawings.

FIG. 1 shows a communication channel system to which the present invention is applied, and FIG. 2 is a block diagram showing the main parts of FIG.

In Figure 1, an extension subscriber telephone (ST
From A) onwards, the communication path switch (SW), central office trunk (COT) or private line trunk (TL'r), equine exchange (CO), or automatic private branch exchange (PABX) constructed by combining switches ) are connected in cascade. Furthermore, an outgoing register trunk (ORT) and an adapter (ORTAP') for the outgoing register trunk are connected to the call path switch (SW), and an outgoing register trunk (ORT) and its adapter (ORTA
Reception for P).

A central control unit (cpU) that exchanges control information is coupled to both. A dial pulse sender (DPSD) is further connected to the central control unit (CPU), and the dial pulse sender (DPSD) receives control information from the central control unit (CPTR) and sends it to the central office trunk (COT). ) sends out an outgoing pulse.

In the communication path system configured as described above, the aspects of the transmission method according to the present invention are as follows.

In Figure 1, when an extension subscriber telephone (STA) goes off-hook, the originating register trunk (OR) follows route (■).
T) and confirm the dial tone.

At this time, information on the accommodation location of the subscriber extension telephone (STA) (
LEN) is sent to the central control unit (CPU).

The subscriber telephone extension (STA) then x+yyy+z
Dial z. Here, X is the access number for accessing the abbreviated dialing code set for other extension subscribers, YYY is the other extension subscriber number that has set the abbreviated code that you are trying to access, and 22 is the abbreviated dialing number. It is a code.

The outgoing register trunk (ORT) is routed by ■.
These dial information are received, and when the first X is received, the information on X is transferred to the central control unit (CPU) (route ■ in FIG. 2).

By receiving the information of Installed extension subscriber telephone (STA)
The accommodation location information (LEN) and information (X) are sent to the adapter (O) attached to the outgoing register trunk (ORT).
RTAP) (route ■ in Figure 2).

The adapter (ORTAP) is connected to the central control unit (CP).
It receives the information X and LEN from U), and then receives the YYY and 22 information transferred from the originating register trunk (ORT) (route ■ in FIG. 2).

Once all the information for X, LEN, YYY and ZZ has been received, the adapter (ORTAP) sends the central controller (
All of this information is sent back to the CPU (route ■ in Figure 2).

The central control unit (CPU) receives this information, analyzes the information @X and LEN, and issues an extension subscriber telephone (ST).
A) and the central office trunk (COT) are connected by the route (■) in Figure 1, and the information YYY and 22 are analyzed and collated, and the subscriber number of the other party corresponding to the information is obtained from the dial pulse sender (DPSD). It is sent out by the route [phase] shown in FIG.

That is, the connection between the extension subscriber making the call at this point and the other subscriber for whom no abbreviated dialing has been set for the extension subscriber is 5TA-8W-COT (
TLT)-Co (PABX) route.

<Effects of the Invention> As explained above, the present invention enables an extension subscriber to make a call by specifying and using an abbreviated dial code set for other extension subscribers. There is an effect that a call can be made by abbreviated dialing even to a subscriber for whom abbreviated dialing is not set for the subscriber.

Claims (1)

[Scope of Claims] In an automatic telephone exchange equipped with a function that allows each of a plurality of extension subscribers to set an abbreviated dialing code, an extension subscriber for making two outgoing calls and an access identification means for an abbreviated dialing code for other extension subscribers. By providing storage means for storage location information, other extension subscriber numbers, and their abbreviated dial codes, the extension subscriber making the call can specify the abbreviated dial code for the other extension subscriber, and An abbreviated dialing system characterized in that an abbreviated dialing connection is made from an extension subscriber to a partner subscriber corresponding to the abbreviated dialing code.
