1. Introduction:

The Single In-Line 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 1.5 Mbps downstream and 512 kbps
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 premise based POTS splitter. Recent field trials of ADSL Lite
equipment jointly carried out by a group of manufacturers and a North America network
operator has proved the technology, achieving maximum data rate for distance up to 15000
feet, 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. The Single In-Line filter for phones
or telephone equipment using a single-line phone jack. The low pass filter provides protection
from ADSL signal which may impact through non-linear or other effects remote devices
( telephone sets, facsimile machine, answering machine, voice band modem, etc. )
individually or in groups on line 1 only. For ADSL signal, it also provides protection from the
high frequency transients and impedance effects that occur during POTS operation ( ringing
transients, on / off hook transients and so on ). This Single In-Line filter also provides a
second jack that is unfiltered for connecting ADSL and / or other high speed digital services
such as HPN.

Because the Single In-Line filter 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 the Single In-Line filter to protect against line
overstress which could damage the Single In-Line filter itself. The electrical and transmission
specifications are designed electronically to meet all the electrical requirements and physical
properties as per T1E1.4/2001-007R3 and isolate the high speed DSL and HPN data streams
from the voice band Plain Ordinary Telephone Service ( POTS ). This design effectively
blocks the ADSL, HPN and other radio frequencies up to 12 MHz.
