General Description

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.

This in-line filter will block the high frequency

energy from reaching the POTS devices and
provide isolation from impedance effects of the
POTS device on G.Lite.

In addition , this filter will also attenuate any

wideband impulse noise generated by the POTS
device due to the interruption of loop current(e.g.
pulse dialing or on hook / off hook transition)

Features

♦Consist exclusively of passive element.

♦Handle all POTS loop currents from

0mA to 100mA.

♦Designed for implementation of ADSL

CPE application.

♦Provides excellent isolation between

DSL and POTS.

♦Designed to meet G.Lite requirement.
