Product Specification
MF604F
1. Introduction:
The MF604F is a “in – line” ( or distributed ) filter 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 allows 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 within intra-campus / intra-building networks. 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 MF604F integrates low pass filter that blocks the high frequency energy from reaching
the POTS device and provides isolation from impedance effects of the POTS device on ADSL.
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
transfer)Because the POTS filter connects directly to the subscriber loop media , it must
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 filter to protect against line overstress which
could damage the filter itself.
