Connecting a
Computer to a
Console Port
You can connect a computer directly to an NBX Network Call Processor,
an analog terminal adapter, digital and analog line cards, and the 3Com
Attendant Console and access CLI commands and system status
messages through a terminal emulation program. Typically, direct access
to the device is for maintenance and troubleshooting purposes and
should be done only under the direction of a support technician.
However, the serial port provides easy access for configuring IP settings
using the nbxIpConfig command (case sensitive).
You can connect a computer directly to these NBX devices:
To connect to the serial port on a 3Com 3105 Attendant Console, you
must use a DB9 (female)-to-RJ-45 adapter.
It does not matter which computer operating system you use. As long as
the computer has a terminal emulation program that can emulate a
VT100 terminal (for example, Microsoft Hyperterminal), it can
communicate with any of the cards listed in
Table 37 .
To connect the computer to the COM1 or CONSOLE port:
1 Using a standard computer serial cable (9-pin male to 9-pin female),
connect the male end of the cable to the female connector (COM1 or
CONSOLE) on the front panel of the board.
2 Connect the female end of the cable to an available serial port on the
computer.
3 Start the terminal emulation software and create a new connection.
