Introduction
General Description
- The
in-Line Micro
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 1.5Mbps downstream and 512Kbps
upstream, depending on line conditions and lengths.
- This
in-line filter will block the high frequency energy form reaching the
POTS devices and provide isolation from impedance effects of the POTS
device on G.Lite.
- In addison, 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 hool transition) This device contain a plastic enclosure
including RJ11 female connector at phone port and RJ11 plug at Line
port.
Advantages:
- Customer Installable:Simply
unplug telephone device from the wall jack and plug line conditioner
into wall jack,then plug telephone device into line conditioner.
- Filters out
any erratic impedance from telephone equipment which would interfere
with ADSL transmissions.
