[Field of Industrial Application] The present invention relates to a communication terminal device connected to a basic interface of an integrated digital service network (hereinafter abbreviated as ISDN), and relates to a communication terminal device connected to a basic interface of an integrated digital service network (hereinafter abbreviated as ISDN). The present invention relates to a communication terminal device for managing calls and receiving calls.

2. Description of the Related Art Conventionally, as shown in FIG.
It was used only for channel access control.

[0003] The terminals 21 and 22 use the D bit to
The E bit, which is a return of the D bit sent to the DSU (line termination unit) side, is monitored to detect whether the D channel is empty.

[0004] Furthermore, even when a free space is detected and the D bit is sent, the D bit sent to the network NT (DSU) side and the E bit (sent to the network NT (DSU) side) D bit) is constantly compared and monitored. D,E
If the bits match, the D bit continues to be transmitted, but if a mismatch is detected, the transmission is immediately stopped and the signal is transmitted again after waiting for the D channel to become vacant. That is,

(a) When a plurality of terminals 21 and 22 simultaneously access the D channel and a competition occurs, the signal on the D channel follows the winning condition. In this case, each terminal 21, 22 has a different terminal number value, so one terminal will definitely survive (when there is a conflict between signals "1" and "0", signal "0" will be on the D channel). ).

(b) Each terminal 21, 22 compares the D bit and E bit sent by the own terminal each time it sends out one bit, and only the terminal 21 that matches the signal continues sending out the signal. Further, the terminals 22 that do not match immediately stop transmitting signals.

[0007] In the basic interface of ISDN, up to eight communication terminal devices can be connected on the same interface. 16K is required for exchanging call control signals between the terminal and the line termination unit (hereinafter abbreviated as DSU).
The D bit of b/s is used, and this and the E bit from the DSU side are used to control competition with other terminals connected on the same interface. Currently, the E bit is used only for this contention control. Furthermore, when each terminal is performing call control, it analyzes the call control information on the D bit from the DSU side, but when another terminal is performing call control, it analyzes the call control information on the D bit. analysis processing is not performed. For the above reasons, each terminal can obtain information about the calls that it originates or receives from the D bits it sends and the D bits it receives from the DSU, but it cannot obtain information about the calls that it originates or receives from other terminals. Information not available. Therefore, in order to manage all the calls that occur on the interface, the user needs to individually manage all the terminals connected to the interface and then collectively manage all the terminals connected to the interface.

[0008]

[Problems to be Solved by the Invention] The communication terminal device according to the present invention not only constantly receives and analyzes the D bit sent from the DSU side, but also performs analysis processing, which was conventionally used only for contention control. By taking in the E bit and performing analysis processing, it is possible to obtain call control information for all terminals on the same interface. The purpose of this is for the user to obtain information regarding all calls occurring on the interface by managing only the call origination/reception management communication terminal device of the present invention.

[0009]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention has an interface means for connecting to the basic interface of ISDN, and a terminal connected by bus wiring via the interface means. Regardless of which terminal is controlling the call, the D-bit analysis processing means always captures and analyzes the D-bit sent from the DSU side, which performs important call control sent from the other party's communication terminal device or network. You can get information.

[0010] Call control is sent from all terminals connected by bus wiring on the same interface to the network or the other party's communication terminal equipment by the E-bit analysis processing means that takes in the returned E-bit from the DSU side and performs analysis processing. You can get information.

[0011] The D bit analysis processing means and the E bit analysis processing means can obtain call control information data regarding all terminals connected to the same interface by bus wiring, and the call control information data is stored by the data storage means. accumulate. comprising an operation display means for inputting an instruction to read information stored in the data storage means and displaying the read information;

In the control section, when operating the communication terminal device to search for call control information, the control section analyzes the input signal using the operation display means, and displays the data based on the analysis result. It performs readout control of the information stored in the storage means and also controls displaying the read call control information on the operation display means. Furthermore, when searching for call control information via a network from a communication terminal device on another interface, the call control information on the D bit sent from the network or the other party communication terminal device via the interface means is searched for. Analyzing the messages and information elements contained therein, controlling the reading of information stored in the data storage means based on the analysis results, and further transmitting information on the bus wiring via the interface means as inter-user information on the D bit, Performs control to output the read call control information.

[0013]

[Operation] In the call originating/receiving communication terminal device of the present invention, there is a D bit analysis processing means that always receives and analyzes the D bit from the network side, and a terminal side connected by bus wiring through the interface means. Since there is an E-bit analysis processing means that takes in the E-bit from the E-bit and analyzes it, it is possible to obtain information regarding all calls occurring on the interface, and the said information can be stored by the data storage means.

[0014] When operating the present communication terminal device to search for call control information, the operation display means and the input/output control means enable reading instructions for call-related information and displaying data corresponding thereto. . When performing a search via a network from a communication terminal device connected to another interface, the input/output control means sends a readout instruction using messages and information elements received from the network side, and the corresponding data network. It becomes possible to send to the other side.
