Title: A method for distributing the local communication lines identifing the data and sound signal
Inventor: LJW
IPC: H04Q11/00
Filed: 2020-07-03
Abstract: The present invention relates to a method for distributing local communication lines identifying data and voice signals, which has a structure divided according to characteristics of each of internal wiring structures, the internal wiring structures including data signals requiring multi-access method (parallel method) via a switching device or hub, a voice call signal requiring direct connection method (serial method) from MDF to an exit. In order to accommodate high-speed data signals, twisted cables are used as wiring materials for the local communication lines, but since the wiring is serially from the MDF to an outlet, it is impossible to achieve a multi-access structure by installing a switching device or a hub in a middle. In addition, if these lines are used in parallel, voice call signals cannot be accommodated. In addition, when constructing an optical cable network between a communication room and buildings, if voice and data are integrated, an optical end station must be installed in each building, which is an unnecessary waste to accommodate a voice channel which does not require advancement of link performance in an optical cable network. According to the present invention, a line for the data signal from the MDF to a building terminal box uses an optical splitter instead of an optical terminal to construct an optical cable network, the present invention has the multi-access structure from the building terminal box through the middle terminal box and a household terminal box to the outlet via a switching hub with a twisted cable, and the line for the voice call signal is in series from the MDF to the outlet. Therefore, a user can access 4-line voice call and 100Mbps high-speed data without additional equipment such as ADSL terminal or cable modem.
