Abstract

To activate normally a number redialing function even in a system where PBX and single trunk lines exist in mixture by applying a correction to a dial signal transmitted in response to the result of comparison between types of a line and a number flag in the number redialing operation.In transmitting the dial signal, when the depression of a number redial operation request button is detected, the active line is detected and whether or not the line when the preceding data is written is a single trunk line is compared. Similarly, the active line and the line when a data is stored are discriminated depending on the state of the number flag. When the line at data write and the active line are the same, the stored dial number is transmitted as it is. When the line is a single trunk line, a conventional telephone number is transmitted and when the line is a PBX line or the like, the number is added with a trunk access code at the head and the result is dialed.

Description

Number repetition method in the multifunctional telephone system

Number repetition method in the relevant multifunctional telephone system of the present invention, particularly about comprising that a phone group of planes that has the push-botton operation dish, the telephone set that makes that is attached thereto realize in the multifunctional telephone system of multi-functional main device and information processing means such as peripheral unit and microprocessor, the other side's telephone number of failing to converse when guaranteeing inerrably to keep a preceding dial-up, the number repetition method that can telephone number inerrably be sent really according to the classification of circuit simultaneously.

In recent years, how to replace the rotating disc type dial telephone set with the so-called button-type telephone set of arranging button on the operation board.Moreover, particularly in the unit that has the multiple phone line road, adopt the multifunction electric telephone system, the multi-functional of indication comprises: have the button-type telephone set of the outside line number of plugging into above unit and the function that any telephone set all has energy and unit external call, with the function of a telephone set maintenance from the accepted call signal of outside, and the function that this accepted call signal is transferred to required telephone set, have the function that communicates with each other between the intramural button-type telephone set and function of telephone number being done shortening processing and storage or the like in addition.The structure of this multifunctional telephone system comprises that many button-type telephone sets and the button-type telephone set that makes that is attached thereto realize above-mentioned multi-functional main device and peripheral unit, and particularly microprocessor of information processing means is housed in main device, button-type telephone body.

Recently, having increased final number again in the function aspects of multifunctional telephone system redials (LAST NUMBER REDIAL) function and keeps number repetition (SAVED NUMBER REDIAL) function.So-called final number redialing function, refer to the other side's telephone number of a preceding dial-up is stored, this is when calling out same the other side again, need only the function that just can finish by a fixed button, when a preceding call operation, under the subscriber engaged or the situation of going out, be very effective when dialling again after a while.

But this final number redialing function is because the telephone number of once dialling before can only storing if after this dialled other telephone number again, just has the problem that the telephone number that has stored is changed.Keep the number repetition function and be with the problem that solves above-mentioned final number redialing function.That is, keeping the number repetition function refers to, before when the other side's who is beaten of once dialling telephone number wants to dial after the short time again, if press the button of regulation in advance, just can make required the other side's telephone number store and be kept, even dialled other telephone number later on again, the telephone number that deposits in is changed, as long as click the function that button just can be exhaled required the other side again at preceding one-stage dialing.This situation, promptly final number redialing function and the attractive part of reservation number repetition function are, can constitute relatively and only can remove automatically after short time work, and relatively just can realize same function through need not special removing after the long period.

On the other hand, in big unit, in order to realize any function that can both converse with the outside of many button-type telephone sets expeditiously, and function such as can communicate with each other between the button-type telephone set of our unit inside, multifunctional telephone system as shown in Figure 1 taked.Promptly, many button-type telephone set BT1～BTn that are provided with in a CO of unit are connected with a main device MD, and between many circuit TLF1～TLFn and this main device MD from the TO of telephone office, being provided with becomes the private branch exchange of one of multifunctional telephone system peripheral unit PBX.This occasion, though aspect the signaling transfer point of private branch exchange inside and outside the raising unit is useful, but night usually for energy-conservation, and when cutting off the power supply of private branch exchange PBX, also just make it to be in non operating state,, will be connected for this reason from the direct and main device MD of several circuit TLS1～TLSn in the line group of the TO of telephone office, can both select these circuits for use for any one of button-type telephone set BT1～BTn, by basic functions such as this method maintenance and the outside directly conversations of unit.

Yet, in functional universal type telephone system as shown in Figure 1,, can produce following problems making above-mentioned final number redialing function and keeping the occasion that the number repetition function is achieved.Promptly, in telephone system shown in Figure 1, when conversation is through private branch exchange system PBX inside and outside the unit, direct dialing the other side's number difference during the commensurate INCOM intercom, during by circuit TLF1～TLFn commensurate external call, to add in the other side's telephone number front usually and dial relaying access code " 0 ".On the other hand, when not by private branch exchange PBX, but through and the diverse direct circuit TLS1～TLSn of TLF1～TLFn circuit during with external call, directly dial the other side's telephone number calling.At this moment, the information processor of finishing original number repetition function is under promptly used number intactly stores during just call operation in number re-dialing apparatus.Therefore, for example, to one-stage dialing before the unit outside is by private branch exchange PBX, and aspect in addition, when conversing again with same the other side, be when directly carrying out promptly carrying out with direct circuit without private branch exchange PBX, owing to added relaying access code " 0 " in the number that number re-dialing apparatus stored, so just produce the problem that to exhale required the other side again, moreover current one-stage dialing is not use direct circuit TLS1～TLSn to carry out by private branch exchange, when but passing through private branch exchange system PBX when exhaling again, opposite with above-mentioned situation so, the number of storage does not have the relaying access code, can not exhale required the other side more equally.

Main purpose of the present invention is, in the multifunctional telephone system of the private branch exchange that has one of peripheral unit, provides a kind of and use and disuse private branch exchange irrelevant, can both be inerrably the outside required the other side's of the unit of exhaling number repetition method again.

For achieving the above object, the feature of method of the present invention is: be connected with main device at many button-type telephone sets, and between from the part of many circuits of telephone office and main device, be provided with private branch exchange, peripheral units such as group telephone mechanism, and, be connected from the direct and main device of all the other circuits of telephone office, at least in the multifunctional telephone system that between intramural telephone set and between the commensurate outside, can both freely converse, can realize the final number redialing function and keep in the number re-dialing apparatus of number repetition function, storage also store talk line when deciding the other side's telephone number kind, when exhaling again, the kind of elder generation's differentiation and external call circuit, again and the circuit kind of information of having deposited compare, revising this circuit kinds of information, thus with fixed the other side's telephone number correctly send.

Below will explain the present invention with reference to the accompanying drawings, but, the present invention is not limited to illustrated example, also comprises the identical method that the application's claim is included.

Fig. 1 is simple line map of using the example of multifunctional telephone system of the present invention of expression, Fig. 2 is the flow chart that the store function of the number re-dialing apparatus in the multifunctional telephone system of the present invention is implemented in explanation, and Fig. 3 is the comparison of this re-dialing apparatus of explanation, the flow chart of debugging functions.

At first illustrate that with reference to Fig. 2 the storage of implementing number re-dialing apparatus of the present invention constitutes.In this case, such as from certain unit when the other side of unit outside makes dial-up operation, wish that one of function that the storage work prior to the number repetition function can be used as multifunctional telephone system can automatically carry out.That is along with the beginning of dial-up at this very moment, storage work as shown in Figure 2 also begins, and detects the telephone number of having dialled in step 101, then in step 102, and the storage telephone number.Further in step 103, whether distinguish promptly distinguish commensurate's external call circuit through private branch exchange system PBX shown in Figure a kind (in other words, direct circuit whether), go to during without private branch exchange system PBX step 104, if go to step 105 during through private branch exchange system PBX.In step 104, the label of storage information is designated as " 0 ", and on the other hand, in step 105, label is designated as " 1 ".Finished after step 104 or 105, storage work just is through with.

In this case, in the time also will making it possess the number repetition of reservation function, then the reservation number repetition of pressing on the telephone set operation board with hand just can be carried out with button.In addition, in the end the number repetition function and keep the number repetition function and the telephone system of depositing in have corresponding redialing respectively and use button, on the other hand, preferably will dial the number deposit in and label write setting respectively.

Exhale again during fixed the other side, carry out the workflow of Fig. 3, determine to have guaranteed the number repetition function.Specifically, along with exhale again, whether the number repetition function comes into effect, in step 201, detect by the button of overweight appropriation, if pressed, then enters step 202.Differentiate whether pass through private branch exchange system PBX shown in Figure 1 in step 202, promptly the kind of differentiation and unit external call circuit if do not pass through private branch exchange system PBX, just goes to step 203, then goes to step 204 during through private branch exchange system PBX.At this moment, the label when step 203 and a preceding dial-up operation shown in Figure 2 compares, when this label is " 0 ",, therefore go to step 205 because the kind of circuit is identical, the telephone number that is deposited in during one-stage dialing before directly sending, number repetition work is promptly accused and is finished.In addition,, then distinguish circuit kind difference, go to step 206 if this label is not " 0 ".In step 206, remove after the relaying access code of interpolation the front of the telephone number that deposits in behind the one-stage dialing in the past, sends the telephone number that does not have code, and number repetition work just is through with.

On the other hand, step 204 too and the label during dial-up operation shown in Figure 2 compare, if label is " 1 ", then the circuit kind is identical, so go to step 205, the telephone number that deposits in during one-stage dialing before intactly sending, the number repetition end-of-job.In addition, when label is not " 1 ", distinguish circuit kind difference, just go to step 207.In step 207, add relaying access code " 0 " afterwards in the preceding telephone number front that once deposits in, send telephone number again, number repetition work has just been finished.

Above-mentioned example is lifted is when conversing with the unit outside, determine the example that circuit grade is different by having or not of relaying access code, the occasion that adopts so-called key system phone CES or and then CES is combined in the occasion of the system of Fig. 1, because the problem that also has the relaying access code to have or not, so can adopt above-mentioned technology item equally.Moreover, Fig. 2, workflow shown in Figure 3 be by the information processing means in the multifunctional telephone system particularly microprocessor realize that this point is probably understood for going together easily.

Adopt the number re-dialing apparatus in the multifunctional telephone system of implementing above-mentioned formation of the present invention, whether having added the relaying access code during for preceding one-stage dialing can correspondingly answer, and the telephone number that is stored sent, thereby can realize number repetition function accurately, thereby can significantly improve the reliability of this system.
