The general Asymmetric Digital Subscriber Line (UADSL) works by increasing the protection belt between the telephone channel and the uplink data band, eliminating the taps that need to be installed on the user side, so it can be called a splitter. A splitter is a device used to separate a telephone channel from a data channel, eliminating the use of a splitter to enable the user to install ADSI. There is no need for specialized technicians to install taps, just buy a "non-residual digital subscriber Line Modem", Plug and Play, as simple and convenient as the current phone-dial modem for general use.
The splitter can separate a plurality of frequency bands from the lines of the wireless communication system into a single frequency band output to different communication lines. The role of the splitter is to shunt the information encoded in the switched network and then to make it revert to its original multiplexing and rate.
