Configuring a Modem
You must configure the modem before you can connect it to the GSS 4490. You
can connect the modem to a terminal or a PC using a terminal emulation program,
such as Hyperterminal. If you connect the modem to the COM port on a PC, you
need the following cable and connectors:
• RJ-45-to-RJ-45 rolled cable
• RJ-45-to-DB-25 modem adapter
• DB-9-to-RJ-45 terminal adapter
Figure B-1 shows the pin number assignments for the 9-pin, male D-shell console
port connector on the back of the GSS 4490. These pin number assignments
conform to the industry standard.
