2.4 Connecting the POTS Splitter
This is for the Prestige that follows the Full Rate (G.dmt) standard only. One major difference between ADSL
and dial-up modems is the optional 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.
