Connecting a POTS Splitter

This is for the P642's following the Full Rate (G.dmt) standard only. One major difference between ADSL
and dial-up modems is the need for a telephone splitter. This device keeps the telephone and ADSL signals
separated, giving them the capability to provide simultaneous Internet access and telephone service on the
same line. Splitters also eliminate the destructive interference conditions caused by telephone sets. The
purchase of a POTS splitter is optional.
Noise generated from a telephone in the same frequency range as the ADSL signal can be disruptive to the
ADSL signal. In addition the impedance of a telephone when off-hook may be so low that it shunts the
strength of the ADSL signal. When a POTS splitter is installed at the entry point, where the line comes into
the home, it will filter the telephone signals before combining the ADSL and telephone signals transmitted
and received. The issues of noise and impedance are eliminated with a single POTS splitter installation.
A telephone splitter is easy to install as shown in the following figure.
Step 1. Connect the side labeled "Phone" to your telephone.
Step 2. Connect the side labeled "Modem" to your Prestige.
Step 3.
Connect the side labeled "Line" to the telephone wall jack.
