1. Introduction:
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.
For POTS voice band service , the low pass filter provide protection from ADSL signal which
may impact through non-line or other effects remote devices(handset, fax, voice band modem
etc)and central office operation . For ADSL signal , it also provide protection from the high
frequency transient and impedance effect that occur during POTS operation(ringing
transients , on-hook,off-hook transient and so on).
Because the POTS splitter connects directly to the subscriber loop media , it must also
provide some protection for externally induced line hits or faults which could damage any
attached equipment or endanger humans interacting with the installed equipment.The circuit
protection will be provided mostly by standard central office line protection means and
additional protection measures built into pots splitter to protect against line overstress which
could damage the splitter itself.
