Next, the operation of the simultaneous communication transmission control system according to the present invention will be explained.

FIG. 5 is a flowchart showing the control contents until the multi-function telephone terminal 102 and the multi-function telephone terminal 106 communicate with each other.

First, a call from the multifunction telephone terminal 102 is transmitted to the line circuit 10.
4 detects and notifies the central processing unit 116 via the line circuit control device 109 (FIG. 5, 501). Next, the central processing unit 116 receives the dial information sent from the multi-function telephone terminal 102 via the line circuit controller 109, and analyzes the received dial information.
2) The destination terminal (multifunctional telephone terminal 106) is called. (Figure 5, 503). Next, when the multi-function telephone terminal 106 responds, the line circuit 108 detects it, notifies the central processing unit 116 via the line circuit control device 110, and sets up a communication path (fifth
Figure, 504). At this time, the central processing unit 116 identifies the class of the extension telephone terminal on the called side (505 in FIG.
). If the extension telephone terminal on the called side is a multi-function telephone terminal, the EXTME allocated in the storage device 117
M table (Fig. 2) shows the accommodation position of the called side's extension telephone terminal (multifunction telephone terminal 106) in the memory area of the calling side's extension telephone terminal (multifunction telephone terminal 102). 5, 506), and extract information on the accommodation location of the extension telephone terminal (multifunction telephone terminal 106) on the called side (Fig. 5, 507), the accommodation location of the called party. The information is stored in the EXTMEM table on the calling party's extension telephone terminal (
It is stored in the memory area of the multi-function telephone terminal 102).

(Figure 5, 510). Note that this stored information is held until the call path is released, and is reset when the call ends.

Next, the operation procedure when data terminal 103 and data terminal 107 communicate while multifunction telephone terminal 102 and multifunction telephone terminal 106 are communicating will be explained with reference to the flowchart shown in FIG.

First, the operator presses the simultaneous communication button 300 (fourth button) shown in FIG.
When one of the various keys 412 in the figure is pressed, the central control circuit 40
1 recognizes this and sends information indicating that the simultaneous communication button has been pressed to the line circuit 104 of the PBX via the line protocol processing circuit 407. The line circuit 104 detects the information and notifies the central processing unit 116 via the line circuit control device 109 (FIG. 6, 601).

Next, the central processing unit 116 analyzes the information that the simultaneous communication button has been pressed, and when it recognizes that the simultaneous communication condition exists, the line circuit control unit of the line circuit 104 in which the multifunction telephone terminal 102 is accommodated. Make a forced call request to 109. Upon receiving the forced call request, the line circuit control device 109 sends information to the multifunction telephone terminal 102 to force the data terminal 103 to make a call (6th @, 6o2). Note that the operation sequence for forced calling is performed by the central processing unit as shown in FIG.

It is controlled by the conditions specified between the line circuit control device and the multifunction telephone terminal, and after execution of the first forced call processing, the state is the same as the condition when the extension terminal (data terminal) goes off-hook. Next, the central processing unit stores the i! Temporarily stores information indicating that a forced call request has been made in the area of the telephone terminal 103 (603 in FIG. 6);
It is determined whether the calling condition from the data terminal 103 is a forced call or a general call.

When the data terminal 103 receives a forced call request from the PBX, it enters the calling state, and the multi-function telephone terminal transmits information indicating that the data terminal 103 is in the calling state via the line circuit controller 109. The central processing unit 116 is then notified. When the central processing unit 116 detects a call from the data terminal 103 (701 in FIG. 7), it refers to the memory area of the extension terminal 1.3 in the EXTMEM table to determine whether the call is a forced call or a general call. (Fig. 7, 702),
If the call is a general call, normal call processing is performed. on the other hand,
If it is identified as a forced call, the forced call information in the memory area of the extension telephone terminal 103 in the EXTMEM table is cleared, and the forced call information stored in the memory area of the RIA telephone terminal 102 in the EXTMEM table is cleared. Extracting location information of the extension telephone terminal 106 (Fig. 7, 703)
, based on that information, calculate the accommodation position of the extension telephone terminal (data terminal 107) that is paired with the extension telephone terminal 106 as the called extension terminal.
4)1. The extension number of the called telephone terminal is extracted from the EXTMEM table allocated to each accommodation position (705 in FIG. 7). Note that the extension number is data registered from the external input device 119 at the time of system configuration. Thereafter, the data terminal 107 is called based on the called extension terminal 107 information, the response from the data terminal 107 is detected by the line circuit 108, and the detected information is notified to the central processing unit 116 via the line circuit control device 110. Ru. Then, the central processing unit 116 recognizes the response from the data terminal 107,
A communication path is established between data terminal 103 and data terminal 107. As a result, simultaneous communication is performed between multifunction telephone terminal 102 and multifunction telephone terminal 106 and between data terminal 103 and data terminal 107.

In the above embodiments, a case has been explained in which the called extension telephone terminal performs simultaneous voice and data communication using a multi-function telephone terminal to which a data terminal can be connected. The telephone terminal does not necessarily have to be a multifunctional telephone terminal.

Next, the called extension terminal receives analog flt,! The operation of the second embodiment will be described when the data terminal is configured independently from the analog telephone.

In FIG. 1, extension telephone terminal 112 is a normal analog telephone. In the memory area of the extension telephone terminal 112 in the E XTMEM table shown in FIG. 2, a simultaneous communication group number is assigned in advance from an external input device to indicate that the terminal is a terminal that performs simultaneous communication control. In addition, the grouping memory (GRPME) shown in FIG.
The M table is a table for simultaneous communication using analog telephones, and stores terminal numbers of extension telephone terminals for voice and extension data terminals for data in correspondence with each other for each group. Note that the GRPMEM table is registered in advance by the external input device 119.

Suppose that the simultaneous communication group number assigned to the extension telephone terminal 112 is 0, and the grouping memory (GRPME
It is assumed that the accommodation position information of the data terminal 114 is registered in the data terminal area of GRPMEMO of the M table).

Here, the multi-function telephone terminal 102 is connected to the extension telephone terminal 11.
2, and when the extension telephone terminal 112 responds (FIG. 5, 501, 502, 503), the central processing unit 116 detects the response (FIG. 5, 504), and the called extension terminal Fifth step to determine whether or not it is a multi-function telephone terminal
If it is not a multi-function telephone terminal, extract the index group number of the GRPMEM table set in the called extension terminal. Call extension group number (GR
