Abstract

PURPOSE:To realize the titled system which makes individual talking with plural called persons through one time operation when a special No. for continuous dialing is dialed, by adding a dial pulse memory trunk to the originating register. CONSTITUTION:A dial pulse memory trunk DPMT is installed to an originating register ORT. Then an extension subscriber A of a private branch exchange can automatically talk with plural other extension subscribers B and C, the trunk line, private lines, the switch box operator, and various services through one time continuous dial operation, because whenever he hangs up the reciver the next called No. and the calling subscriber A are automatically called. Moreover, when the called No. is busy, the connection is automatically made when the busy condition is over. Thus, individual talking with plural subscribers can be made continuously.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for consecutively dialing a plurality of calls in an automatic private branch exchange.

Conventionally, in automatic private branch exchange equipment, when an extension subscriber wants to talk to multiple i-subscribers individually, the calling subscriber goes on-hook after each call ends and calls the next subscriber. After going off-hook again, it was necessary to dial the numbers of the most valuable subscribers each time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for communicating between a calling subscriber and multiple called subscribers.

The multiple call continuous dialing system of the present invention connects a called number storage device to a dialed number analysis device of an automatic private branch exchange,
When the calling subscriber calls multiple subscribers consecutively, the calling subscriber dials the called subscriber number after the special number to obtain the multiple subscribers corresponding to the p1 calling subscriber information. It is characterized in that call subscriber information is stored in the storage device and connections are made one after another.

Below, 1 of the present invention! J! Examples will be explained with reference to the drawings. Figure 1 is a relay system diagram of an embodiment of the present invention;
1 is a block diagram of the central control unit and transmission register of the embodiment of the invention shown in FIG. 1. FIG.

Returning to Figure 1, A, B, and C are extension telephones, IOT is an internal trunk, ORT is a call register, and DPMT is a dial pulse memory trunk that stores dialed numbers and special numbers. ). When extension telephone A goes off-hook, a dial tone connection is made and connected to call register 0FtT. A person using a phone with a cough dials a special number for continuous dialing after receiving a dial tone. This dial pulse is the transmission register OR'l'
The number is counted and temporarily stored in the calling register 0)tT as a special number for continuous dialing. Furthermore, when the extension telephone mA dials the special number followed by the called subscriber number,
This dial pulse is counted and analyzed by the transmission register ORT and sent to the central control unit CCU together with the special number information temporarily stored previously.

For example, if a person using an extension telephone hears a dial tone, 8-
If you dial XXX-YYY-ZZZ (8 is a special number for continuous timetables, XXX, YYY, and Zzz are the desired called subscriber numbers) in succession, they are counted and analyzed by the calling register ORT, and the number information and The calling subscriber's accommodation location information is transferred to the dial pulse memory trunk DPMT. The outgoing register ORT is then restored. Also, the accommodation location information of the calling subscriber is sent from the central control unit @CCU to the calling register ORT when the dial tone is connected, and is temporarily sent to the ORT.
After being stored in the memory trunk DPMT, the end-of-dial information is transferred to the memory trunk DPMT along with other information. The dial pulse memory trunk DPMT has a special number for continuous dialing (8P
), calling subscriber accommodating location information (LEN), and M call subscriber number 1 (XXX, YYY, and HZzz), and transfers this information to the central control unit CCU. In this case, by first transferring the information SP, LEN,
, LEN, YYY) to the memory link DPMT Kl! seek

Further, when the connection between XXX and the calling subscriber is completed and the call is running, the central control unit CPU sends connection completion information to the memory trunk DPMT, and the memory trunk DPMT erases the XXX information. Thereafter, zzz and the calling subscriber are connected in the same way. All connection completion information for XXX and ZZZ from the memory trunk DrMT central 111Jll device CCU is restored after death. In addition, numbers XXX, YYY and ZZZ
If any of them is busy, the central control unit CCU sends busy information to the memory trunk DPMT and requests the dial pulse memory trunk DPMT to transfer the next called subscriber number. Finally, a connection is made to the called subscriber whose busy information has been stored, but if the called subscriber is still busy at this time, the central control unit CPU sets mutual extension camp-on and makes a connection. When the called subscriber becomes free, a call is automatically made and a connection is established to call the called subscriber. The intra-office trunk IOT is a trunk that connects extensions A and B% or A and C. Figure 1 shows the link of switch 8W■
After the connection, links ■ and ■ indicate the call letter li of A and B,
After this, when the person goes on-hook, a ringing message is automatically sent to both A and the next called party C, and in response to both parties' responses, A, ! : Enters C's talking state.

In FIG. 2, route (2) indicates a normal call information transfer route, and (2) and (2)-1.2.3 indicate a call information transfer route according to the method of the present invention. That is, ■/■-1. ■／
It is transferred with the combination of -2 and Matasha ■/■ -3.

In addition, although this explanation uses an extension subscriber as an example of the called party, this method is applicable even if the called party is a central office line, dedicated line, central office relay stand operator, or various services. is possible.

As can be seen from the above explanation, by adding a dial pulse memory trunk to the calling register, by dialing a special number for continuous dialing, it is possible to talk to multiple called parties individually with a single dialing operation. have an effect.

Claims (1)

[Claims] Continuous dialing of lf: from an extension subscriber of an automatic private branch exchange device, dialed station *, dedicated number, extension subscriber 1 line relay stand operator, or termination of each call for various services. Each time the later-calling extension subscriber puts the handset on-hook, the remaining number of other subscribers and the calling subscriber are automatically called and connected one after another. This multi-call continuous dialing system is characterized in that it is possible to talk individually and consecutively to a plurality of rare partner subscribers by automatically calling and connecting when a subscriber becomes idle.
