The in-Line Micro filter has been specifically designed to implement the functionality of low pass filter in G.Lite system.G.Lite technology is similar to full rate ADSL in using DMT technology but operates at a lower data rate of up to 1.5Mbps downstream and 512Kbps upstream ,depending on line conditions and lengths.ADSL Lite is proposed as a lower speed version of ADSL that will eliminate the need for telecom to install and maintain a premises based POTS splitter. It was found necessary to include one or more low pass filters in series with the POTS terminals in order to reliably achieve maximum data rates.
