Product Specification

MF608B

1. Introduction:

The MF608B 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 MF608B 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.
