Prestige 650 ADSL Router 
Hardware Installation and Initial Setup  
 
2-5 
 9600 baud rate. 
 Parity set to none, 8 data bits, 1 stop bit. 
 Flow control set to none. 
After the Prestige has been successfully connected to your network, you can make future changes to the 
configuration via Telnet or the embedded web configurator. 
2.4  P650 with POTS  
Sections 2.4.1 and 2.4.2 relate to people who use their P650 with ADSL over POTS (analog telephone 
service) only. 
2.4.1  Connecting a 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.
