1. Introduction:
The MF600SWE 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 intracampus. 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 aseparated plastic box ).
The MF600SWE 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. The electrical and transmission specification is based on ETSI
TR 101 728 and castomer requird .
