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.
