Description

ADSL Reverse Wiring Filter {omitted}

The present invention relates to an ADSL reverse wiring filter. More specifically, the Y-type distributor, a micro filter, a telephone module, and the like, which are installed at the end of a communication line to use the ADSL service provided by KT, are integrated. It is about the ADSL reverse wiring filter which enables the simultaneous operation of the telephone, the telephone and the fax.

Generally, ADSL stands for "Asymmetric Digital Subscriber Line" and is called "Asymmetric Digital Subscriber Line". It is a modem technology that enables high-speed digital service by using ordinary telephone line (or two twisted copper lines). Are different and are used for high-speed Internet access. In addition, by forming two different frequency bandwidth, it can be used for telephone and fax when sending and receiving data. In the ADSL technology, as illustrated in FIG. 1, a telephone connection and a data communication signal having two different bandwidths in the KT 3 are loaded on the DSLAM 1 equipment and attached to the telephone telephone pole through the core wire 2 at a time. It is sent to the outside line 6 through the terminal box 5, and then two mixed signals arrive at the subscriber line 7 and the telephone 4-hole outlet 8 again. Here, a signal is sent to the ADSL modem 9 and the telephone through the Y-type distributor 13, respectively. However, since the Y-type divider 13 only has a function of simply separating the signals, the two signals are still mixed, and the signal going to the ADSL modem 9 is a different problem because the ADSL modem receives the two signals simultaneously. Is not generated, but if the data signal is left in the signal to the phone 11 is a variety of abnormal operating conditions, such as noise, signal disconnection phenomenon, the filter must be filtered by the micro filter 10. In addition, when there are two or more telephones in the ADSL subscriber's home, as shown in FIG. 2, the micro filter 10 is attached to the front of the telephone 11 to filter the data signal. In this method, the larger the number of telephones, faxes, etc. in the ADSL subscriber's house, the more micro filters 10 are required, and the larger the number of micro filters is attached, the more data signals are divided so that the quality of the ADSL service is reduced. This can cause a drop in speed and disconnection from the Internet. In order to prevent the indiscriminate use of such a micro filter and to improve the quality of communication service, as shown in FIG. 3, a Y-type splitter is connected to a four-prong outlet for a telephone, and one line is connected to an ADSL modem and connected through a UTP cable 14. The computer 12 accesses the Internet. The other line enters the spare outlet HOLE 18 of the four-hole outlet 8 through the filter 10 and the telephone cable 15 and is connected to the spare line 16 inside the wall. This signal is again routed to the telephone via a spare outlet. In this case, since a micro filter is installed before the HOLE for the preliminary outlet, the data signal is already removed. However, the method shown in FIG. 3 cannot solve the loss of the data signal due to the failure and deterioration of the premises 7, the outer line 6, and the spare line 16. In order to solve these problems, as shown in FIG. 4, the outdoor UTP cable 23 is constructed directly from the telephone connection terminal 5.

Inside the outdoor UTP cable 23, there is a reverse reverse line 19 for drawing and a reverse reverse line 20 for drawing. The incoming reverse wiring line is connected to the core wire 2 and connected to the Y-type distributor 13 in the home. In the Y-type distributor, one side is connected to the ADSL modem 9 and the other side is connected to the reverse wiring line 20 for drawing again through the micro filter 10. Since the outgoing wiring line 20 for drawing is connected to the existing outside line 6, as a result, the facilities inside the subscriber's house below the outside line 6 are not changed at all, and a new communication line is constructed, thereby providing data due to the internal circumstances of the house. No loss However, when installing such a reverse wiring facility, a single part is assembled by hand, which requires a lot of time and parts, and also causes a problem of re-visiting the connection failure and failure report.

The purpose of the present invention is to integrate parts such as Y-type distributor and micro filter when installing ADSL reverse wiring facility, simplifying the work in subscriber's house, improving ADSL quality, reducing working cost, and improving the appearance by making parts compact. It is to improve the work efficiency and reduce the after-sales rate.

According to the present invention, when the ADSL service provided by KT is connected to the crimping connector 36 of the reverse wiring termination part, the ADSL reverse wiring filter 24 for easy installation of the ADSL facility is connected to the communication signal inlet connector 26. ), Surge absorber 32 to protect ADSL communication modem from lightning strike, condenser 33 for passing alternating current and blocking direct current, filter 34 for separating data signal and voice signal, filtered voice signal The audio signal output connector 27, ADSL modem connection connector 28, and telephone connection connector 29 are installed.

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

6 shows an application diagram using the ADSL reverse wiring filter 24 according to the present invention. The Y type distributor 13 and the micro filter 10 shown in FIG. 5 are integrated to the ADSL reverse wiring filter 24. Replaced. The reverse wiring filter 24 enters the ADSL signal through the connector 26 for communication signal entry and passes through the surge absorber 32, which is an abnormal voltage caused by a lightning strike or a collision accident invading through the communication line. When this happens, it protects the ADSL modem from further voltages. The signal passing through the surge absorber 32 passes through the capacitor 33 again. In the capacitor, the AC current passes through and blocks the DC current to protect the ADSL modem secondaryly. The ADSL signal is sent to the voice signal output connector 28 and the telephone connection connector 29 by the filter 34 which separates the data signal and the voice signal from the printed circuit board 35, and the voice signal output connector ( 28, the outgoing reverse line 20 is connected to the voice signal to the telephone connection terminal box (5). You can use a separate telephone for the dial connector. At this time, it is possible to construct and use a telephone line very usefully without the four-hole outlet 8 for the telephone in the home. The data signal of the separated signals is connected to the ADSL modem in the ADSL modem connection connector 28 so that the Internet can be used. Various connectors and components are located on the upper part of the printed circuit board 35. The circuit connecting the respective parts is connected to the upper part of the printed circuit board, and the ADSL signal moves along the circuit to make the Internet and the telephone available at the same time. Therefore, since the ADSL reverse wiring filter 24 is used, it is possible to reduce the time due to the production of a large number of telephone crimping modules during the line work, and to connect and test the Y-type distributor 13 and the micro filter 10 with each other. It can reduce the work and can solve the problems that may occur when leaving the telephone line. The ADSL reverse wiring filter 24 is also very useful for external modems and internal modems when installing ADSL facilities using reverse wiring.

As described above, according to the present invention, by using the ADSL reverse wiring filter 24 when installing the ADSL facility, the Y-type distributor 13 and the micro filter 10 and the cables that must be manufactured when connecting each of the ADSL reverse wiring work. Since the telephone module (RJ-11) is not necessary at all or the number of manufacturing is considerably reduced, the work time is shortened, the work cost is reduced due to the reduction of parts, and the simple appearance makes the finishing of the line neat. In addition, the improvement of the ADSL quality and the reduction of the after-sales service rate caused by the reverse wiring and the reverse wiring filter 24 contribute to enhancing customer satisfaction and reliability, which are fundamental ADSL services.
