Abstract

PURPOSE:To simplify the automatic originating control and to facilitate the trunk line origination of the desired dial code, by constituting a format of the originating information of the trunk access, the dial and each special code. CONSTITUTION:The automatic dial information comprising a trunk originating code X, a dial code Y and a special code Z is registered and stored 6. Then the automatic dial information is read out by an automatic dial operation of the telephones 3 (3a-3n), and the idle trunks 4 (4a-4n) are caught according to the code X. Then the code Y is transmitted via the trunk 4. At the same time, the code Z is detected when an idle trunk is caught by setting a call-back to the busy state of all trunk lines. Then only the code Y stored after the code Z is extracted and fed to a station through the trunk 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic dialing method that can effectively send a dialing code to a 9-station trunk when waiting for a trunk.

In a private branch exchange, as the call volume increases, the central office line trunk may become completely busy. When the extension terminal tries to make a call when all lines are busy, the extension terminal dials a special number or operates a special key to set the exchange to wait for a free trunk, and as soon as a free trunk becomes available, it will receive a free trunk notification and make a call. [Rank automatic waiting is performed.]

On the other hand, the above-mentioned private branch telephone exchange has an automatic dialing function that registers a speed dial and a dial code, which is a telephone number, in advance by dialing a special number or operating a special key, and then automatically dials the above dial code in response to the speed dial from the extension terminal. is now set up.

These functions have many effects on the cape that can improve exchange services.

Now, FIG. 1 shows a schematic configuration of an exchange system equipped with these functions, where l is the main body of an electronic exchange such as gPABX. However, the switch main body IK is subscriber circuit 2.
Multiple extension terminals (telephones) 11 to 1n via 1 to 1n
are connected, and a plurality of office lines are connected via office line trunk circuits 41 to 4n. In addition, the central control unit (cc) 5
are the subscriber circuits 2-2fi and trunk circuit-1.
'-111, and also sends and receives programs and control data to and from the memory to control one exchange operation of the exchange main body l.

Now, when making a call to a central office line from the extension terminals 11-am in such an exchange, the call is generally made by inputting a trunk access code and then inputting a dial code.

The main switchboard 1 receives the trunk access code, seizes one of the vacant trunk circuits is to 4n, and transmits a dial code to the central office line via the trunk circuits 4a to 4n. Further, when the automatic dialing function described above is used, as shown in No. 211(a), outgoing call information B consisting of a trunk access code and a dialing code that have been alerted in advance by inputting a speed dial is read out from the memory, After the trunk circuit is captured by the above access code, a dial code is transmitted over the central office line as indicated by CK.

However, when a call is made to a central office line after the above-mentioned automatic waiting for a vacant trunk is performed, the following problems occur. That is, after receiving a waiting notification for an empty trunk, if you respond to the notification and enter the trunk access code and dial code, it will take time from the response to receive the trunk access code and seize the 9-way trunk. During this time, there is a possibility that the empty trunk will be used again due to an incoming call from the central office line. Therefore, in the past, a device has been devised in which an empty trunk is detected and captured at the same time at the time of an exclusive one-way meeting, and a dial code is input and sent from the terminal following a response to the empty trunk notification. However, if an attempt is made to use automatic dialing by changing the speed dial due to the response during automatic waiting for an empty trunk, as shown in Fig. 3(b), an empty trunk is already captured and the system is not registered in advance. Since the transmitted information B is read out, the same 1%1l is sent to the central office line.
As shown in D of (b), there was a problem in that all call information including the rank access code was sent, resulting in incorrect dialing.

The present invention has been made in consideration of these circumstances, and its purpose is to always be able to stably and accurately call a central office line by automatic dialing, regardless of whether automatic waiting is performed for an empty trunk. The aim is to provide a highly practical automatic dialing system.

In other words, the present invention provides an automatic dialing system that allows a user to make a call to a central office line using a desired dialing code for simple AK without using separate speed dials with different methods for making a normal call and temporarily waiting for an empty trunk automatically. be.

The outline of the present invention is to configure the format of the call information that gives an alarm as automatic dialing information to include a trunk access code, a dialing code, and a special code inserted between these codes, and when automatically dialing, the special code is inserted. By detecting this and transmitting only the dial code whose data is separated by a special code to the central office line, it is possible to always transmit the dial code correctly even when automatically waiting for an empty trunk.

At the same time, by using this method, it is possible to unify outgoing call information between the normal automatic timetable V time and the automatic dialing time when waiting for an empty trunk, and to simplify the automatic call control, thereby effectively achieving the above purpose. This is what we achieved.

Hereinafter, a method according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 3 is a diagram showing the concept of automatic dial processing in the embodiment system, and FIG. 4 and FIG. S are diagrams showing its control form.

With this method, the call information that will be automatically dialed is as follows:
As shown in FIG. 3, the dial code Y is sent to the trunk access code X0 station.

This call information is composed of a special code 2 (!:) inserted between these codes Read from

Then, the central control device S detects the special code 2 in this read out transmission information, and divides the trans access code X and dial code Y according to this special code 2.
They each have an independent knowledge of each.

Then, when one of the central office line trunk circuits 4a to 4n is captured using the trunk access code XK, or when a 9-tone trunk is captured by automatic waiting for an empty trunk, only the recognized dial code Y is transmitted through the trunk circuit. Control operation is performed to make a call to the central office line. Also, whether or not to capture an empty trunk using the above-mentioned trunk access code XK is determined by setting a flag in the storage area corresponding to the extension terminals 1 to 1n, and when the flag becomes ``1'', depending on the response to the empty trunk automatic waiting function. It is determined that the trunk has already been captured, and if the above flag is rOJK, it is determined that the building is a normal automatic dialer, and the above access code XK is added to capture an empty trunk.Now, the extension terminal The information input from 11 to 1fi is detected by the input detection program 11 as shown in FIG. If transmission is necessary, the dial sending program IIK data is passed through the dial sending queue l-.And when the extension terminals j1 to 1n operate automatic dialing V or speed dialing, the call processing program 13, a dial string is written in the input waiting queue 12.

FIG. 6 shows the processing flow of this call processing program 11. That is, when self-dial data or abbreviated dial data is input to the call processing program, the content of the above-mentioned flag corresponding to that extension terminal is first referred to.

Then, if the flag is rlJ, that is, automatic queuing of empty trunks is performed, first set the above flag to "O".
JK is reset, the special code described above is detected, a dial code delimited by this detected special code is detected, and this is written into the input waiting queue 12. Further, when the flag becomes rOJ, the alarm data string indicated by automatic dialing or speed dialing is written as is into the input waiting queue JjK. and call processing program I
By executing J, the input waiting queue rz< written dial data is transferred to the dial exit program Z#,
By dialing K, it becomes possible to send only the dial code to the central office line.

In this 5KL, by processing the call information table, you can simply set the # special code in the call information in advance, and it will be the same for both normal calls and empty rank automatic waiting calls. You can use automatic or speed dialing. Furthermore, it is possible to always ensure that a vacant trunk is captured, and only the dial code can be sent to the central office line via the trunk. Therefore, extension terminal 1a~
With jnvc$, the service function of the exchange machine can be effectively utilized through easy operation, and the practical advantages are extremely large.

In the case of private branch exchanges, until the other party's exchange to which the trunk is connected becomes capable of receiving Diagram V.

It may take 111 degrees to complete. If the special code is used for this time adjustment, there is no need to insert a dialing delay code immediately after the trunk access code, which has a great practical advantage.

As described above, according to the II method, it is possible to effectively send out only the dialing code to the central office line, regardless of whether or not there is automatic waiting for vacant trunks. There is no need to change the method.

Therefore, it is possible to provide an automatic dialing system that is not only easy to handle and can fully utilize its functions, but also has a simple processing flow, which is highly effective for practical use.
