Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention enables two calls to be made with one call operation on a telephone line.
The present invention relates to a two-line interlocking control method for performing a line origination operation.

[Prior art] Conventional, analog or digital telephone line 2
In a communication method using lines, one for voice communication and the other for non-voice communication such as still images or moving images, calling operations have been 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 calling operations must also 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.

[Means for solving problems]

The two-line interlocking control method according to the present invention has a correspondence table of the telephone number of the voice communication line and the telephone number of the non-voice communication line to be connected, and makes a call from the voice communication line to the voice communication line of the other party. After confirming that the voice channel communication has been established, the CPU searches the correspondence table for the telephone number of the non-voice communication line of the other party based on the input telephone number of the other party's voice communication line. If the telephone number of the other party's non-voice communication line is not registered in the correspondence table for the telephone number of the other party's voice communication line entered above, the telephone number of the other party's voice communication line is automatically called. This will automatically make a call to the other party's terminal.

[Effect]

In this invention, when the telephone number of one line is oscillated, the telephone number of the other line corresponding to this line is automatically dialed. Furthermore, if the telephone number of the other line corresponding to the line is not registered, an automatic call is made to the other party's terminal using the telephone number of the other party's voice communication line.

〔Example〕

FIG. 1 is a line connection diagram showing an embodiment of the present invention, in which 1 is a telephone that notifies the calling telephone number and operating status to the outside; 2 is a telephone that analyzes the notification information from the telephone 1 and makes a line call; FIG. , a control device for controlling incoming calls and starting and stopping terminals; 3 is a terminal; 4 is an exchange. Note that A and B are either the transmitting side or the receiving side, but for convenience of explanation, A will be described as the transmitting side and B as 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, 8 is a CPU (processor), and 9 is a line control section.

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 using a telephone 1 on the sending side A, 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 inputted from the telephone interface section 5 in the telephone telephone number column of the correspondence table shown in FIG. 4 in the memory 7, and finds the corresponding telephone number. Reads the phone number for the corresponding terminal. For example, if the input phone number is "03-123-4567", search for this from the correspondence table in Figure 4,
Corresponding terminal phone number "03-098-7654"
Read out.

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.

Thereafter, when the other party's telephone 1 picks up the receiver (off-hook), communication between the telephone 1 on the sending side A, the exchange 4, the exchange 4, and the telephone 1 on the receiving side B is established. At that time, a notification that communication has been established is sent from the telephone 1 to the telephone interface section 5 of the control device 2. In control device 2
When the CPU 8 detects this notification, it instructs the line control unit 9 to perform outgoing call processing using the terminal phone number previously 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. Other party's line control unit 9
performs reception processing and establishes communication. Then each
The CPU 8 instructs the terminal control unit 6 to transmit input/output information from the terminal 3 onto the communication line for terminal communication.

Furthermore, when the telephone 1 is hung up during the communication (on-hook), the telephone communication via the exchange 4 is disconnected. The notification of the disconnection is sent from the telephone 1 to the telephone interface section 5 of the control device 2.
will be notified. In the control device 2 that received the disconnection notification,
The CPU 8 instructs the terminal control section 6 to stop operation, and also instructs the line control section 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. Process outgoing calls using the same number as the phone number. 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 between the phone number of the voice communication line and the phone number of the non-voice communication line to be connected, and allows a call to be made from the voice communication line to the other party's voice communication line. After confirming that the voice channel communication has been established, the CPU searches the correspondence table for the phone number of the non-voice communication line of the other party based on the input phone number of the other party's voice communication line, and automatically calculates this number. If the telephone number of the other party's non-voice communication line is not registered in the correspondence table for the telephone number of the other party's voice communication line entered above,
Since the telephone number of the other party's voice communication line is used to automatically make a call to the other party's terminal, there is an advantage that communication on two lines can be established with one calling operation.

Claims (1)

[Claims] 1. In a communication method that uses two analog or digital telephone lines, one for voice communication and the other for non-voice communication, the telephone number of the voice communication line and the telephone number of the non-voice communication line to be connected. When a call is made from a voice communication line to the other party's voice communication line, after confirming that the voice channel communication has been established, the non-voice communication of the other party is based on the entered telephone number of the other party's voice communication line. The CPU searches the correspondence table for the phone number of the line you want to use, and automatically calls the number.
If the telephone number of the other party's non-voice communication line corresponding to the entered telephone number of the other party's voice communication line is not registered in the correspondence table, the telephone number of the other party's voice communication line is automatically used to make a call to the other party's terminal.
