[Problem to be solved by the invention] By the way, the above-mentioned ISDN terminal device or PB
In addition to standardized communication services, some X systems have their own communication services for faster speeds, etc. In such a case, it becomes necessary to confirm common unique services that can be executed between the ISDN terminal device and the PBX, and conventionally, the user had to perform the above confirmation process himself.

The present invention has been made to solve the problems of the prior art as described above, and its purpose is to provide an ISDN terminal device that can automatically recognize unique services that can be executed between an ISDN terminal device and a PBX. There is a particular thing.

[Means for Solving the Problems] In order to achieve the above object, an ISDN terminal device according to the present invention includes a communication control unit that performs a standard communication service in ISDN and a uniquely set communication service in addition to the standard communication service in ISDN, and a private branch exchange. an ISDN terminal device including a coupling part to which a standard connector of a unified standard connected to a line is coupled, wherein the standard connector is provided with a mark that fits within the uniform standard shape, and the standard connector and the coupling part are coupled. a mark detector that detects a mark provided on the standard connector when the mark is detected; and, when this mark is detected, whether or not the unique communication service set on the terminal device itself is set on the private branch exchange. and a selection means that selects, by comparison, a unique communication service common between a terminal device and a private branch exchange as a unique communication service that can be executed by the communication control unit.

[Operation] In the ISDN terminal device of the present invention having the above configuration, by detecting the mark attached to the plug or socket, which is a standard connector of the basic interface, it is possible to grasp the unique service provided by the terminal itself and the private branch exchange. , select unique services that can be executed between the terminal device and the private branch exchange.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing an ISDN terminal device according to an embodiment of the present invention.

In the figure, (30) is an ISDN terminal device of the present invention. (32) is a terminal control device that supervises control in the ISDN terminal device (30), and is composed of, for example, a CPU. Reference numeral (34) denotes a voice data terminal function section, which is provided with terminal functions such as telephone (voice) and facsimile (data), and processes the input/output signals according to the terminal functions.

Reference numeral 36 denotes a man-machine interface section, which is composed of, for example, a liquid crystal panel, indicators, etc., and displays messages, operation displays, subscriber numbers, etc.

(38) is a coupling part to which a standard connector (40) connected to the line of a PBX (private branch exchange) (10) is coupled.

In this embodiment, the standard connector (40) corresponds to, for example, the plug (20) shown in FIG.
8) corresponds to the socket (22).

FIG. 2 is a front view showing the standard connector (40) of this embodiment, and FIG. 3 is a side view showing the coupling portion (38).

In FIG. 2, the tip of the standard connector (40) is provided with a mark (42) that fits within the unified standard shape of a plug conforming to I58877.

This mark (42) is composed of, for example, at least one dip (44).

The standard connector (40) as described above is inserted into the coupling part (38) shown in FIG.
48) comes into contact. As a result, the ISD in Figure 1
N terminal device (30) and PBX (10) are connected.

In Fig. 1, (50) is a mark detector, which is composed of, for example, a microswitch, and has a standard connector (
40) is inserted into the coupling part (38), the presence or absence of the dip (44) of the standard connector (40) is detected.

A communication control unit (52) controls standard communication services in ISDN, that is, communication capabilities provided by ISDN to customers (subscribers), as well as communication services uniquely set by, for example, a manufacturer.

(54) is a verification means, and when the mark detector (50) detects the dip (44), the unique communication service set in the ISDN terminal device (30) itself is
BX (10) is set.

Reference numeral (56) is a selection means, which selects the unique communication service common between the ISDN terminal device (30) and the PBX (10) as a unique communication service that can be executed by the communication control unit (52) based on the above-mentioned comparison.

The operation of the above configuration will be explained with reference to FIG. First, the standard connector (
40) is inserted into the joint (38), the mark detector (50) identifies the presence or absence of the dip (44). If there is a dip (44), the verification means (54) notifies the PBX (10) of specific terminal service ID information indicating the unique communication service. And verification means (54)
performs negotiation of an executable unique communication service with either the terminal device (30) or the PBX (10). This negotiation is started by notification of ID information from the terminal side. Also, the negotiation is 16k
Any means may be used, such as a bps control channel (Dch packet), user-user information (UUI), or an original procedure.

Through such negotiation, a common proprietary communication service possessed by the ISDN terminal device (30) and the PBX (10) is selected. Such selection process is performed by PB
The same process is performed in X(10), and the selected unique communication service is notified from the PBX (10) to the ISDN terminal device (30) as a communication service that can be provided by the PBX (10). And a communication control unit (52)
and PBX (10) provides the selected proprietary communication service if given instructions.

On the other hand, if the dip (44) is not detected, the communication service in the communication control unit (52) is limited to only the standard communication service, and the ISDN terminal device (30) of the present invention operates as a normal standard ISDN terminal device. . In this case, of course, specific terminal service ID information is not sent,
No matching operation is performed.

Note that until specific terminal service ID information is notified from the ISDN terminal device (30) and negotiation of services that can be provided begins, the ISDN terminal device (30) and PBX (10) will not use the normal standard service provided by ISDN. Provide communications only.

Further, in the above embodiment, a mark detector (
50), but the present invention is not limited to these means. For example, mark (42) is placed on a reflective sheet (
A mark detector (50) which optically detects this mark (42) may be provided, which is made of a light-shielding member or the like (any color). Furthermore, it is also possible to configure the mark (42) with a conductor or the like and provide a mark detector (50) that electrically detects the mark (42).

Furthermore, the mark (4) provided on the standard connector (40)
2) may be placed anywhere on the connector as long as it can be detected.

Furthermore, in the above embodiment, when the standard connector (40) is inserted into the coupling part (38) of the terminal device main body, the process after mark detection is performed, but the standard connector (40)
0) is inserted into the coupling part (38), and the plug (20) at the other end of the standard connector (40) is inserted into the socket (22) provided on a wall or pillar, etc. The processing of the invention is done in a similar manner. That is, the processing of the present invention is performed when the mark (44) is detected and the ISDN terminal device (30) and PBX (10) are connected.

[Effects of the Invention] As explained above, according to the ISDN terminal device according to the present invention, when the terminal device is connected to the line of the private branch exchange,
Since the unique communication service that can be provided is automatically selected based on the detection of the mark attached to the standard connector, there is no need for manual selection work, and human selection errors can be eliminated. Therefore, even if the terminal device is moved and connected to a different line, there is no need to manually select the unique communication service again, and the user's inconvenience can be reduced.
