The communication line sharing device 20 includes a telephone line L2 and data lines L6 to L12 provided from the hub 10.
Are provided as input, common lines L14 to L20 are provided.
The common lines L14 to L20 are connected to each installation location (room 1
Or to the common sockets S31 to S34 provided in the room 4). The user sets the common socket S31
By connecting a telephone jack or a run card jack to S34, a telephone call or data communication can be performed.

Hereinafter, the communication line sharing device 20 will be described in detail with reference to FIG. Communication line sharing device 20
Performs the following functions:

First, the telephone line L2 and the data lines L6 to L12 provided from the hub 10 are connected to provide a common line L14 to L20.

Second, when two or more telephone numbers are used, for example, pairs 4 and 5 of telephone lines (UTP cables) supplied to each household are used for the first telephone number, and 2
If the number pair is used for the second telephone number, data communication via a run card using data lines (UTP cable) 1, 2, 3, 6 and the telephone line (UTP cable)
In order to solve the inconvenience of collision of telephone calls through the second telephone number using the first and second pairs, the first and second pairs of the telephone line (UTP cable) L2 for the second telephone number are used. A switch (for example, SW1 to SW4) performs a function of switching to the fourth and fifth pairs of telephone lines L32 to L38.

Finally, when a 100 Mbps run card is used at a specific installation location, a common line (UTP cable) is used.
The connection pins of the run cards corresponding to the fourth and fifth pairs and the seventh and eighth pairs are short-circuited. At this time, when a telephone call is tried at another installation location, a run during the call is solved. Performs card connection detection and call prevention functions.

As shown in FIG. 3, the telephone line L2 is divided and input to each of the switches SW1 to SW4, where the switches SW1 to SW4 are used to perform the second function described above. Things. Referring to FIG. 4, when the second telephone number is used via the first and second pairs of telephone lines L2 and the second telephone number is used in room 1, the switch SW1 is connected to the telephone line L2. 1 and 2 can be connected to the 4 and 5 pairs of the telephone line L32. As described above, the user can freely select and use any one of a large number of telephone numbers at each installation location using the switches SW1 to SW4, and use the run card at another installation location. Can prevent collision with data communication.

Therefore, each of the switches SW1 to SW
4, the telephone lines L32 to L38 connected to the telephone line L2 supplied to each household use only the fourth and fifth pairs for telephone communication, and the communication line couplers 40 to 46. Are connected to the respective data lines L6 to L12 provided from the hub 10. Communication line coupler 40
Common lines L14 to L20 connected by
Is connected to each installation location (room 1 to room 4).

On the common lines L14 to L20 connected to the respective installation locations (rooms 1 to 4), there are run card connection detection and call error prevention units 48 to 54.
The run card connection detection and call error preventing sections 48 to 54 have a function of preventing a call phenomenon occurring when data communication is performed using a 100 Mbps run card.

As shown in FIG. 5, when data communication is performed using a 100 Mbps run card in the socket S31 of the specific installation location (room 1), the common line L14 is paired with the fourth and fifth pairs and the seventh and eighth lines. The connection pin of the run card corresponding to the pair is short-circuited. Therefore, the run card connection detection unit 5
6 monitors the UTP cable 7 and 8 pairs, and then detects the short circuit of the UTP cable 7 and 8 pairs,
The run card connection signal is supplied to the switching control signal of the relay circuit 58 via the line L50. Relay circuit 5
Reference numeral 8 opens lines 4 and 5 of the UTP cable in response to the run card connection signal. By using such a method, it is possible to prevent a phenomenon during a call that occurs when a telephone call is tried at another installation location (for example, the room 2).

Although the present invention has been described with reference to particular embodiments, it is not intended that the scope of the invention be limited to the details described above, but without departing from the scope of the invention. The vendor will be able to make various modifications.
