Prestige 643 ADSL Router
Hardware Installation & Setup 2-3
Step 4. Connecting the Console Port
For the initial configuration of your Prestige, use terminal emulator software on a computer for configuring
your Prestige via 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 workstation. You can use an extension RS-232 cable if the enclosed one is too short.
2.3 Additional Installation Requirements
In addition to the contents of your package, there are other hardware and software requirements you need to
meet before you can install and use your Prestige. These requirements include:
A computer with an Ethernet 10Base-T/100Base-T NIC (Network Interface Card).
A computer equipped with communications software (for example, Hyper Terminal in Win95)
configured to the following parameters:
VT100 terminal emulation.
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.
2.4 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.
