8.3 Rear Port Configuration
This section provides information on setting up and configuring the rear port modem device (or a direct

The Alpha Cordex Controller (CXC, Alpha P/N 018-557-20 or 018-587-20) supports connection to one of
the following:
• Alpha-supplied internal modem daughter board module (via rear RJ-11 jack), or
• External AT-class V.34 or V.90 modem (via rear RS-232 serial port with DB-9 connector), or
• Null modem direct cable connection (either front or rear RS-232 serial port) to a computer running
Windows 2000.
8.3.1 Internal Modem Support
The V.90 internal modem (Alpha P/N #707-329-20) module requires the CXC to be supplied with List Op-
tion 101 (modem module supporting global usage); which includes the List Option 95 Communications
Board assembly.
8.3.2 External Modem Support
The CXC also supports the use of a standard external AT-class V.34 or V.90 modem (e.g. US Robotics
Sportster 33.6 or similar). The external modem must be connected by a standard DB-9 straight through
serial cable to the rear RS-232 serial port (requires the CXC to be supplied with the List Option 95 Com-
munications Board assembly).
