Product Specification

MF600SWI

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.
