About Microfilters
A microfilter is a small device designed to reduce interference between ADSL signals and your
regular telephone signals.
The use of microfilters is only required if your ADSL modem and your telephone devices share
the same wiring. This is known as ‘splitterless’ ADSL. Without microfilters, ADSL may cause
background noise on your phone. Additionally, ADSL data transfer may be interrupted by
phone calls.
Note: To test if the telephone jack you are using for ADSL is shared by another telephone jack
in your location, connect a plain telephone to the telephone jack intended for use by the
Diva 2440, and connect another telephone to the other telephone jack. Pick up the phone on
one jack and have someone else pick up the phone on the other jack, then talk. If you hear the
other person talking, the two jacks share the same wiring.
If microfilters are required, you must install one on each telephone device that shares the same
wiring as the ADSL signals, including telephones, answering machines, and fax machines.
If your installation uses a splitter, it should not be necessary to use microfilters as ADSL data is
carried on separate wiring up to the point of entry to your location. Contact your provider for
more information.
Your package may or may not include a microfilter. If you are unsure as to how to connect
the microfilter, or whether or not one is necessary, contact your ADSL provider.
Connecting a Microfilter
To install the microfilter, plug your phone or other analog device into the microfilter, then plug
the microfilter into your telephone jack, as shown below.
You must use one microfilter per telephone device in your location.
As telephone standards vary from region to region, your telephone equipment may vary than
those illustrated here.
Note: Do not install a microfilter on the cable that connects your ADSL device to the telephone
jack. It is also unnecessary to use a microfilter on the Diva 2440’s built-in phone port.
