2.2.4 Connecting the Console Port
For the initial configuration of your Prestige, you need to use terminal emulator software on a computer and
connect it to the Prestige through the console port. Connect the 9-pin end of the console cable (9-pin to 25-
pin console cable supplied) to the console port of the Prestige and the 25-pin end to a serial port (COM1,
COM2 or other COM port) of your computer. You can use an extension RS-232 cable if the enclosed one is
too short.

2.4 Connecting a POTS Splitter
This is for the Prestige following 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. A POTS splitter 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.
