Step2
Configuration on the administrator side
The PC and the modem are correctly connected, the modem is connected to a telephone cable, and the
telephone number of the remote modem connected to the console port of the remote switch is obtained.
NOTE:
Note the following device settings:
• The baud rate of the Console port is lower than the transmission rate of the modem. Otherwise, packets
may be lost.
• The parity check mode, stop bits, and data bits of the console port adopt the default settings.
Step3 Perform the following configurations on the modem that is directly connected to the device:
AT&F ----------------------- Restore the factory defaults
ATS0=1 ----------------------- Configure auto-answer on first ring
AT&D ----------------------- Ignore data Terminal Ready signals
AT&K0 ----------------------- Disable local flow control
AT&R1 ----------------------- Ignore Data Flow Control signals
AT&S0 ----------------------- Force DSR to remain on
ATEQ1&W ----------------------- Disable the modem from response to commands and save the
configuration
To verify your configuration, enter AT&V to show the configuration results.
NOTE:
The confi
g
uration commands and the output for different modems may be different. For more information,
see your modem’s user guide.
Step4 Launch a terminal emulation utility (such as HyperTerminal in Windows XP/Windows 2000), and create
a new connection (the telephone number is the number of the modem connected to the device).
NOTE:
On Windows 2003 Server operatin
g
system, you need to add the HyperTerminal pro
g
ram first, and then
log in to and manage the device as described in this document. On Windows 2008 Server, Windows 7,
Windows Vista, or some other operating system, you need to obtain a third party terminal control
program first, and follow that program’s user guide or online help to log in to the device.
Step5 Dial the destination number on the PC to establish a connection with the device, as shown in Figure 20
through Figure 22.
