Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a system for assigning terminal identification numbers, and particularly to a system for assigning terminal identification numbers to terminal equipment connected to a home bus of a subscriber of a digital integrated network.

(Prior Art) Recently, the development of technology for connecting a digital integrated network and terminal equipment of subscribers receiving services from this network has been promoted. As one of the results of this development, a connection system between a subscriber exchange and subscriber terminal equipment as shown in FIG. 2 has been proposed. That is, a network terminal #3 is installed in the subscriber's premises,
A digital subscriber is connected to the subscriber exchange 1 via 2. On the other hand, network terminal equipment &3 includes various digital terminal equipment examples, uj: packing machine TgL1, TBL2.77ri7<'7
FAXq data terminal DT, etc. are connected via bus 4 (or star wiring). Furthermore, in order to facilitate the movement of terminals, a flexible branch is provided on the bus 4 and a receiving connector is provided for each, or a receiving connector is provided at the end of the star wiring, and various digital terminals with a unified connection format can be freely connected. I am making it possible to connect to. The network terminal device 3 is provided for synchronization between the main digital terminal device and the exchange 1. This digital terminal notifies the exchange 1 of the terminal conditions for each call so that the terminal can receive network services suitable for the terminal, and one of the terminal conditions is that the digital terminal connected to each network terminal f13 There is a terminal identification number that identifies the device.

Conventionally, this terminal identification number is given to a number setting circuit in the terminal device for each terminal device introduced into the subscriber's home, a number that does not overlap with the number of the previously installed device.

(Problem to be solved by the invention) However, as the number of terminal devices introduced increases and they are repeatedly discarded or replaced, managing numbers becomes a hassle, and the system requires configuration work inside the terminal devices each time. , there is the inconvenience that setting errors can also occur.

The purpose of the present invention is to eliminate the above-mentioned inconvenience and provide a terminal identification number assignment method in which a terminal identification number can be set simply by connecting a digital terminal device to a nine-key connector that has been spoofed to a bus in advance. There's K things to do.

(Measures to solve the problem) As mentioned above, this terminal identification number is notified to the exchange as one of the terminal conditions for each call, so it must be kept unchanged during one communication. There is no problem even if the terminal identification number is changed so that it does not overlap with other terminal identification numbers when the terminal identification number is not used.

Therefore, the receiving side 2 is installed at the branch end of the bus connected to the network terminal device or at the end of the star wiring connected to the network terminal device.
A number-designated connection is provided on the connector, and this designated number is transmitted to the terminal equipment when the connector of the home terminal is inserted and connected to the receiving connector, and the terminal equipment uses this number as the terminal condition for each call. It may be installed and sent to the exchange. In this case, when the subscriber installs the in-house wiring and receiving connectors at the required locations, each terminal device can be connected to which receiving connector as long as each number-specified connection is made once without duplication. . The present invention is based on the above idea,
In a terminal connection connector, a terminal for transmitting and receiving information, a connection for specifying a terminal identification number inside the receiving connector, and a terminal for transmitting and receiving a terminal identification number are configured.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention, in which a home bus 4 is connected to a network terminal &3 connected to a subscriber exchange of a digital integrated network via a digital subscriber line. n receiving side connectors CR, , C8 to CRn are branch-connected to , and arbitrary terminals TEA, TEB to TEK of the receiving side connectors are connected to insertion side connectors CP, CPS to CP, respectively. This shows the case where both are connected. Each connector has the same structure, and a terminal device connector can be inserted into either receiving side. Four of the connector connection terminals are used for sending and receiving information between the terminal device TB person ~ TFSK and the home bus 4, and six is used for sending and receiving terminal identification numbers. In other words, when the six terminals of the receiving connectors CR, to CRn are installed on the domestic bus 4, one of the 31 different connections between a specific terminal and the other five terminals is connected inside the connector. , is applied without duplication with other connectors, and is used to send the terminal identification number. Next, connect the insertion side connectors of terminal equipment '1'gA and TgK to CP
When t is connected to the receiving connectors OR, ~CRn, the in-home bus 4 and the terminal equipment TE are connected via the four terminals for transmitting and receiving information.
A-TBK is connected, and the terminal devices TEA and T
The terminal identification number is sent from WK to a specific one of the six terminal identification number terminals, and the terminal identification number is given to the terminal equipment '13A to TBKK as the terminal returns to one of the other five terminals. become. Therefore, the terminal equipment TgA-TgK reads this terminal identification number for each call, incorporates it into one of the terminal conditions, and sends it to the exchange.

Therefore, connect the terminal equipment TEA, TgK to another receiving connector CR.
5-CRn, the terminal equipment will send the terminal identification number connected to the receiving connector for the next call, but the exchange will transmit the terminal identification number for each call. Since this number is accepted and processed as the equipment number connected to subscriber #2 until the end of the call, no problem occurs.

In the example of FIG. 1, up to 31 (it) receiving connectors CR, -CRn of the domestic bus 4 can be provided, but if the number of terminal identification number terminals of these connectors is increased,
It is clear that the number of receiving connectors can be increased to transmit unique terminal identification numbers, and the number of terminal devices can also be increased.

(Effects of the Invention) As explained in detail above, the present invention provides a system in which terminal equipment connected to a digital integrated network reports terminal conditions to an exchange for each call, from inside the receiving connector connected to the in-house path. Since the individual number of the receiving connector is sent to the connected terminal device and used as the terminal identification number, there is no need to set a number inside the terminal device, and there is no need to perform special management of the terminal identification number. Any terminal device can be connected to any residential bus receiving connector.
