Abstract

PURPOSE:To attain the terminal connection precluding the possibility of dialing an erroneous number with simple operation by using two kinds of prescribed designation numbers in the of communication in a composite communication system. CONSTITUTION:In case of the communication from a terminal equipment F to A, the operator dials an extension number (987) to connect a communication system to which the terminal equipment A belongs in the upper most communication system (CES) 7 to which a communication system is connected. A number detection circuit 1 receives the extension number to information the reception to a control circuit 3. The circuit 3 discriminates it depending on the storage content of a storage circuit 2 that the extension number designates the communication to the terminal equipment with the extension number '1' in the same communication system as the caller terminal equipment F and controls a number sending circuit 4 to allow it to send an extension number '0' to set a line with a main controller 9 of the communication system to which the terminal equipment F belongs. After the line is set with the main controller 9, the extension number '1' of the terminal equipment A is sent to a main controller 7.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a terminal connection control method that enables individual calling of terminals and main controllers in a composite communication system consisting of a plurality of communication systems arranged in one layer. It is something.

(Prior art and its problems) An example of a communication system is the office collective telephone system (
cEs), private branch exchange telephone system b (PBX),
Examples include button telephone systems and calculator systems.

At offices, etc., CES, P
A combination of BX, key telephone system, etc. may be installed.

FIG. 1 is a diagram showing an example of the configuration of a conventional composite communication system in a business office or the like.

In FIG. 1, a table shows the relationship between the number to be dialed when communicating with terminal A housed in the first button telephone main device 9 and the housing position of the calling terminal.

As is clear from the table, when communicating with the same terminal A, many different numbers (four types in the example in the table) must be dialed depending on the location of the source terminal. Not only is it cumbersome to operate, but it also has drawbacks such as the risk of dialing the wrong number.

Although this explanation deals with the case of telephone calls (voice communication), the same problem also occurs when non-telephone communication or simultaneous telephone and non-telephone communication is carried out, such as in computer systems and so-called OA systems. ing.

(Objective of the Invention) It is an object of the present invention to provide a terminal connection method which eliminates the problems mentioned in item 2 and which is easy to operate and eliminates the possibility of dialing an incorrect number.

(Structure of the Invention) When a communication system consisting of multiple terminals and one main control device is installed independently, it is generally necessary to dial the network line number from outside the system and dial the extension number from within the system. do it.

However, in a composite communication system in which multiple such communication systems are connected (as in the case shown in Figure 1), each communication system differs depending on the positional relationship between the sender and the communication partner, as illustrated in the table (in the case of the table above). (4 types) You need to dial a number. This made the operation cumbersome and there was a risk of incorrect dialing.

In the present invention, a designated number (for example, a telephone number) sent from a terminal or a main control device is once read by either the terminal or the main control device, or both, and the structure of the composite communication system stored in advance is read by each terminal. By referring to the designated number of the controller or main controller and converting the designated number sent by the operator or device into a designated number suitable for connection, only two types of designated numbers can be used regardless of the configuration of the composite communication system. All terminals and main control devices can be called individually, eliminating complicated operations and preventing erroneous dialing.

This will be explained in detail below using one drawing.

FIG. 2 is a block configuration diagram of an embodiment showing a device configuration for realizing the present invention, and is an example in which a designated number conversion function is provided in a terminal.

In the figure, 1 is a number detection circuit that receives designated numbers from the keyboard, panel, etc., 2 is a storage circuit that stores the overall system configuration, designated numbers of each terminal and main controller, and 3 is a number detection circuit. A control circuit 4 determines a designated number to actually be sent from the detection result 1 and the storage contents of a storage circuit 2, and a number sending circuit 4 actually sends out the designated number under the control of the control circuit 3. Further, 5 is a designated number input section operated by the operator, and in this embodiment, a mechanical contact such as a dial switch or a keyboard is used.

Next, the operation of FIG. 2 will be briefly explained using the composite communication system of FIG. 2 as an example.

As an example of connection, let us consider the case of communication from terminal F to terminal A in FIG.

The operator connects the communication system to which terminal A belongs in the third-most communication system (CES 7 in FIG. 1) to which the communication system to which terminal A belongs (the button telephone main device 9 for each section in FIG. 1) is connected. The extension number required to establish a line (
Dial "987" (in FIG. 1).

The number detection circuit 1 receives this information and the reception result is “987.
” to the control circuit 3. The control circuit 3 determines from the contents of the memory circuit 2 that “987” specifies communication to the terminal with extension number “’1” in the same communication system as the originating terminal F. It is determined that there is. Then, in order to set up a line with the main control device of the communication system to which the terminal F belongs, the extension number ItO11 of the main control device is sent to the number sending circuit 4.
control to send out. After setting up the line with the main controller, the extension number II i I of terminal A
+ is sent to the main controller.

At this time, if the extension number LL i I+ of terminal A is not specified, communication will be directed to all terminals within the communication system (an example of this is communication with so-called electronic bulletin boards, electronic circulation boards, etc.).

In this way, regardless of the location relationship between the source and destination,
A designated number that is always fixed (the extension number (dial number) necessary to establish a line to the main control device of the communication system 11 to which the destination belongs in the first communication system to which the communication system to which the destination belongs is connected). If there is an extension with in-line function, dial the number), set up a line with the main controller of the communication system, and then send it when communication starts (the extension number of the i-destination terminal within the communication system). By transmitting , it becomes possible to individually call any terminal and main control device within the composite communication system.

Next, if the source is the same terminal or device outside the multicomponent communication system as the destination, the station number (dairef1-
- DI combined with an extension with in-line functionality
(If there is an outside line, that number) ("0123-4" in Figure 1)
56-7890") and set up a line with the main controller of the communication system to which the destination belongs, then dial the extension number "1" of the terminal in the communication system to which the destination terminal belongs. By sending the information to the device, it becomes possible to individually call any terminal and main control device of the entire complex communication system.

FIG. 3 shows another embodiment of the present invention, in which the main controller is provided with a designated number conversion function.

In the figure, 1 is a number detection circuit that receives designated numbers from each terminal, 2 is a storage circuit that stores the overall system configuration and designated numbers of each terminal and main controller, and 3 is a number detection circuit for the number detection circuit 1. A control circuit 4 determines the designated number to be actually transmitted from the reception result and the contents stored in the storage circuit 2, and a number sending circuit 4 actually transmits the designated number under the control of the control circuit 3.

Further, 6 is a switching circuit for making the specified general code conversion circuits 1 to 4 available to a plurality of terminals, and 10 is a terminal having a function of sending a specified number to the main control device using hardware or software.

Note that in this embodiment, numbers are used as designation numbers, but names, affiliations, positions, etc. may be used instead of numbers.

Further, although the designated number is sent using mechanical contacts, it is of course also possible to use software control.

(Effects of the Invention) By performing the operations described above, in the composite communication system, ■ the designated number for mutual communication within the composite communication system;
All terminals and main control devices can be called individually from inside and outside the complex communication system by simply using two types of numbers: the designated number for communication with parties outside the complex communication system, making operations less complicated. This has the advantage of being able to eliminate errors and prevent incorrect dialing.
