Description

Insertion splitter for WDSL {INSERT TYPE SPLITTER FOR xDSL APPLICATION}

The present invention relates to an insert type splitter which is inserted into an IDF terminal and separates and connects a voice signal and a data signal transmitted from a cable of a subscriber. More specifically, a jumper operation is performed even when a subscriber moves. The present invention relates to an insert splitter for xDSL that can be restarted by moving the splitter without the need for this.

DSL (Digital Subscriber Line) has various kinds of transmission technologies such as Asymmetrical Digital Subscriber Line (ADSL), Symmetrical Digital Subscriber Line (SDSL), and Very High Digital Subscriber Line (VDSL) depending on the transmission band and transmission technology. Called xDSL. Among them, ADSL technology is a technology that recycles current copper cable subscriber line to provide high speed data service of several Mbps along with telephone service per line, and xDSL which can build digital line using current copper line. It's a kind of technology.

ADSL is a so-called "asymmetric digital subscriber line", which allows voice and data to be used simultaneously by dividing the band between 0-4KHz for voice and 4KHz-2.2MHz for data with a conventional telephone line (copper line). While the data flow in the Internet is mostly received from the server (downward), the data generated by the user is not much (upward). Accordingly, the channel efficiency is increased by channelizing the downlink / uplink and allocating different bands to reflect the data flow. In other words, the downlink speed is 1.5 to 8Mbps and the upstream speed is 16 to 640Kbps, and since the downlink data from the server occupies most of the Internet, the service is performed at a high downlink speed.

ADSL is currently in service in Korea in large scale, so large-scale facility investment is being made in the domestic and apartments. To provide this ADSL service, DSLAM (Digital Subscriber Line Access Mulitiplexer) equipment is installed in the telephone station or subscriber's area, and the ADSL line (Voice + Data signal) is transmitted from the splitter connected to the equipment. It is separated by telephone).
