Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

Figure 2 is a block diagram of an embodiment of an integrated generation communication distribution device operable during power outage according to the present invention.

Integrated generation communication distribution device (A) according to the present invention is composed of a data communication distribution unit 20 and telephone trunk line distribution unit 40. The telephone trunk line distribution unit 40 may accommodate a telephone line of up to four lines when connected to the RJ45 modular jack. The telephone trunk line distribution unit 40 distributes the input telephone line and supplies it through a plurality of output ports. The user can easily use the telephone of the desired line by connecting the telephone to the telephone line output terminal installed in each room.

The data communication distribution unit 20 includes a power supply unit 21, a data uplink port 22, a multiplexer 23, a plurality of LAN ports 24-31, and an automatic direct connection unit 50. In this embodiment, the case where there are eight LAN ports available for data communication is taken as an example, but it is obvious to those skilled in the art that the number of LAN ports can be expanded as needed.

The power supply unit 21 supplies power for the multiplexer 23 to operate. The power supply unit 21 supplies a 3.3V DC voltage to the multiplexer 23 through a 3.3V DC adapter. The data uplink port 22 is a terminal for inputting a data communication line drawn out from the workgroup switching hub. The data uplink port 22 is formed of an RJ45 modular jack. The end of the data communication line withdrawn from the workgroup switching hub is formed with an RJ45 modular plug to connect with the data uplink port 22.

The multiplexer 23 is operated by DC power supplied by the power supply 21, and switching to enable data exchange between one data uplink port 22 and a plurality of LAN ports 24-31. Perform the hub function. The LAN ports 24-31 are formed by RJ45 modular jacks, and are connected to data terminals installed in each room of a generation. The end of the data communication line is formed with an RJ45 modular plug, which is connected to the LAN ports 24-31. By connecting a computer to the output terminals installed in each room, data communication such as the Internet is possible. The power supply unit 21, the data uplink port 22, the multiplexer 23, and the LAN ports 24 to 31 implemented according to the present invention are the same as those implemented in the conventional integrated generation communication distribution apparatus.

Automatic direct connection 50 may be implemented by two relays (51, 52) as shown in FIG. The first relay 51 is a relay connected to the data uplink port 22 side, and the second relay 52 is a relay connected to the LAN port side usable in the event of power failure. The LAN port usable at the time of power failure is set to the LAN port 24 in Figs. 2 and 3, but it is apparent to those skilled in the art that the LAN port can be set to any one of the plurality of LAN ports 24-31. The automatic direct connection unit 50 connects the data uplink port 22 and the multiplexer 23 to each other in the normal case in which DC power is supplied to the multiplexer 23 so that data can be connected to the data uplink port 22 and multiplexed. The communication unit 23 communicates via the LAN port 24-31. The automatic direct connection unit 50 connects the data uplink port 22 directly to the LAN port 24 that can be used even during a power failure when the DC power is not supplied to the multiplexer 23 due to a power failure. Allow communication without going through (23). The LAN port 24 which can be used in the event of a power failure is connected to a communication device such as a notebook computer capable of data communication even in the event of a power failure.

An operation of the integrated generation communication distribution device A in which the automatic direct connection unit 50 is built according to the present invention will be described in detail with reference to FIGS. 2 and 3.

When the DC power is supplied to the multiplexer 23 by the power supply 21, the multiplexer 23 operates normally, and the first relay 51 and the second relay 52 of the automatic direct connection unit 50 are connected. The switches of are interlocked and connected to the contacts a and c, respectively. Therefore, data is transmitted through the data uplink port 22, the multiplexer 23, and the LAN ports 24-31. The multiplexer 23 multiplexes and transmits data to a LAN port to which a data communication device such as a computer is connected.

On the other hand, if the DC power is not supplied to the multiplexer 23 by the power supply unit 21 due to a power failure or the like, the multiplexer 23 does not operate and the first relay 51 of the automatic direct connection unit 50. And the switches of the second relay 52 are connected to the contacts b and d, respectively. Thus, data is transmitted through the data uplink port 22 and the available LAN port 24 in case of power failure without passing through the multiplexer 23. The notebook computer is connected to the LAN port 24 usable in the event of power failure, so that the user can perform data communication even in the event of power failure.
