The correct DSL Filters and splitters prevent the high frequency noise used by ADSL modem from being heard on

a phone handset. A filter (or splitter) is essential wherever a telephone or other PSTN device shares the line with

an ADSL modem. Both devices perform the same function however a splitter divides the signal into two parts; one

containing the ADSL signal and the other filtered to only contain the voice, whereas Filters block the ADSL signal

completely and allow the voice to go through.

Splitters typically have 3 labeled sockets- ADSL/Modem, Phone and Line/Wall Sockets.

TO USE A SPLIT TE R

STEP 1: Connect you telephone devices (E.G. phone, fax or answering machine) to the Splitter socket labeled ‘phone’

STEP 2: Connect your ADSL modem to the Splitter socket labeled ADSL/Modem

STEP 3: Connect your line/wall Splitter socket to your wall socket

NB: If you have other telephone wall sockets on the same telephone line you will need to plug in filters between

the phone and the wall socket. If you need to parallel more than three filters on one ADSL telephone line it is

recommended you install a central splitter.

A central splitter must be used if a premise has an alarm/emergency dialer, more than 3 PSTN lines, or multiple

sockets. It must be installed by a qualified communications technician before the first phone point on the property.
