1. Introduction:

The CPF105G is a splitter module that has been specifically designed to implement the
functionality of low pass filter in POTS over ADSL application.

Asymmetric Digital Subscriber Line (ADSL) technology is dedicated , point to point ,
public network access technology that allow multiple forms of data , voice , and video to
be carried over twisted-pair copper wire on the local loop between a network service
provider’s (NSP ’S) central office and the customer site or on local loops created either
intra-building or intra-campus. Best of all , ADSL delivers this high speed performance
over existing copper telephone line all while allowing traditional voice service to coexist
without interruption through POTS low pass filters. The POTS-splitter on the customer
premises side consists of a lowpass section(installed in a separated plastic box.

The CPF105G integrate low pass filter that block the high frequency energy from
reaching the POTS device and provide isolation from impedance effects of the POTS
device on ADSL. In addition , these 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 transfer) 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.
