Abstract

PURPOSE:To attain automatic calling with a telephone number of other line corresponding to a calling at one line by providing a corresponding table managing telephone numbers of corresponding two lines. CONSTITUTION:When a telephone set 1 at the reception side hooks off by the call processing of a telephone set at the sending side, the notice representing the establishment of communication is sent to a telephone set interface section 5 of a controller 2. When a CPU 8 of the controller 2 retrieves a telephone number list for telephone set in a corresponding table managing the telephone numbers of corresponding two lines in a memory 7 and finds out a telephone number the same as the telephone number inputted from an interface section 5, since the CPU 8 reads a telephone number of corresponding terminal set and gives a command of call processing to a line control section 9, communication for two lines is confirmed.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention enables x of two telephone lines to be
The present invention relates to a two-line interlocking control method for performing A communication operation.

[Conventional technology]

Conventional, analog or digital 'RL talk line 2 times I
In a communication method using IN, where one side performs voice communication and the other side performs non-voice communication such as still images or moving images, calling operations are performed separately for each line.

[Problem that the invention seeks to solve]

Since the conventional communication method handles the two lines independently as described above, it has the disadvantage that the outgoing operation has to be performed separately.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and relates to a two-line interlocking control method that automatically realizes corresponding transmission operations on two lines by a single oscillation operation.

[Flat membrane to solve problems]

The two-line interlocking control method according to the present invention has a correspondence table in which telephone numbers are registered in advance, and when a call is made on one line, a call is automatically made using the telephone number of the other line that corresponds to the telephone number. is to be carried out.

[Effect]

In this invention, when the telephone number of one recollection is retrieved, the telephone number of the other line corresponding to this line is automatically dialed.

〔Example〕

FIG. 1 is a line connection diagram showing an embodiment of the present invention, in which 1 is a calling telephone number, a telephone that notifies an operating state to the outside, 2 is an analysis of notification information from the telephone 1, 1 is a call for a line 1 A control device that controls incoming calls and starts and stops the terminal;
3 is a terminal, and 4 is an exchange. In addition, A,
B is the transmitting side or the receiving side, and although K is also the same, for convenience of explanation, the explanation will be made assuming that A1 is the transmitting side and B is the receiving side.

FIG. 2 is a functional block diagram of the control device 2, in which 5 is a telephone interface section, 6 is a terminal control section, 7 is a memory, and 8 is a C
PU (processor) 9 is a line control unit.

FIG. 3 shows an example in which the telephone number of the receiving side is registered as a representative number, and on the receiving side B, the telephone 1 and the control device 2 are connected to one exchange 4.

FIG. 4 shows a correspondence table between telephone numbers for telephones and telephone numbers for terminals.

Next, the operation will be explained.

In FIG. 1, when a dial number is input from the telephone IK of the transmitter 11A, the telephone interface section 5 of the control device 2 is notified of the originating telephone number.

In the control device 2, the CPU 8 searches for the same number as the telephone number input from the telephone interface section 5 using the correspondence table for telephones shown in FIG. , reads the corresponding terminal phone number. For example, if the entered phone number is r03-
123-4567J, search for this in the correspondence table in Figure 4.

Corresponding terminal phone number r 03-098-76
Read out 54J.

On the other hand, as a result of the call processing from the telephone 1, the bell of the telephone 1 of the connected party is rung as a preprocess for establishing communication via the exchange 4.

After that, when the other party's telephone 1 picks up the receiver (off-hook), the sending party A's telephone 1 - switchboard 4 - switchboard 4
- Communication on the voice channel of the telephone 1 of the receiver B is established. At that time, the telephone 1 sends a notification to the telephone interface unit 5 of the control device 2 that communication has been established. In the control unit fl12, when the CPU 8 detects this notification, it instructs the line control unit 9 to make a call using the terminal telephone number read from the correspondence table. The line control unit 9 performs a calling process and notifies the other party's line control unit 9 to be connected via the exchange 4. The line control unit 9 on the other party performs reception processing and establishes one communication. After that, each CPU 8
The input/output information of all three terminals is transferred to the communication line to perform terminal communication.

Further, during the communication, when the telephone 1 is hung up (on-hook), the telephone communication via the exchange 4'e is disconnected. The notification of the disconnection is sent from the telephone 1 to the control device 2.
This notification is sent to the telephone interface section 5 of the telephone. In the control device 2 that has received the disconnection notification, the CPU 8 instructs the terminal control unit 6 to stop operation, and also instructs the line control unit 9 to disconnect the line, thereby stopping communication processing.

On the other hand, if the telephone number input from the telephone interface unit 5 does not exist in the correspondence table shown in FIG.
The terminal number 8 is considered to be the same as the telephone number for the VM stuffing machine, and the control device 2 performs outgoing processing using the same number as the calling telephone number of the telephone set 1. The line connection method in this case is as shown in FIG. 3, where the same number is registered as a representative number, and the telephone 1 is connected to the parent line of the representative number, and the terminal 3 is connected to the slave line.

〔Effect of the invention〕

As explained above, the present invention has a correspondence table that manages the telephone numbers of two corresponding lines, and when a call is made on one line, the call is automatically processed on the other line corresponding to this telephone number. This has the advantage that two lines of communication can be established with one call operation.
