Embodiment Construction

[0013] For a better understanding of the present invention, reference is made to the conventional ADSL service communication system shown in FIG. 1 . As shown, the communication system includes a splitter module 7 with a splitter module input terminal 71a, a POTS connection terminal 71a', and an ADSL connection terminal 71a". The POTS splitter card 3 has a built-in LPF ( low-pass filter) and HPF (high-pass filter). The input splitter module trunk line terminal board (SPM-IN) and the output splitter module trunk line terminal board (SPM-OUT) are additionally installed on the MDF4. POTS points After the liner card 3 is installed in the line splitter module 7, the trunk line terminal boards 8 and 9 are connected to the line splitter module 7. Specifically, the U-shaped groove terminal 81a' included in the trunk line terminal block 8 and the line splitter The splitter module terminals 71a of the modules 7 are interconnected by cables. Similarly, the U-shaped groove terminals 91a' ...

Abstract

The present invention relates to a ADSL service communication system comprising the OSP terminal board connectting to the POTS (Plain Old Telephone Service) splitter card which connects to the user terminals. The ISP terminal board connects to the OSP terminal board and the POTS system. OSP and ISP terminal board allow the ADSL to connect here. The ISP terminal board comprises a plurality of pairs of connectors, and the POTS splitter card consists of a small-sized board and a POTS splitter installed on the board. The POTS aplitter card mixes the data signals and the voice signals and distributes the obtained signals. The POTS splitter card is connected to the connector.

Description

technical field [0001] The present invention relates to an ADSL (Asymmetric Digital Subscriber Line) service communication system comprising an OSP (Outside Port) terminal board connected to a POTS (Plain Old Telephone Service) splitter, connected to the OSP terminal board and An ISP (Inside Port) terminal board for POTS systems, and an ADSL system connected to the ISP terminal board, with POTS splitters connected to subscriber terminals. Background technique [0002] Typically, an ADSL service communication system includes a POTS splitter card necessary for ADSL service and including a low-pass filter and a high-pass filter. POTS splitter cards mix data and voice signals and distribute the resulting composite signal. First, the POTS splitter card is installed to a splitter module that includes terminals dedicated for POTS connections and ADSL connections. In addition, the input and output splitter module trunk line terminal boards are mounted to the MDF (Main Distribution...
