USB port on the G250/G350 (see Table 2 ).
Accessing the CLI via a serial modem
1. Connect a modem to the Console port on the front panel of the Avaya G250/G350 Media
Gateway. Use an RJ-45 serial cable to connect the modem.
2. Make sure the Console port is properly configured for modem use.
3. From the remote computer, create a dialup network connection to the Avaya G250/G350
Media Gateway. Use the TCP/IP and PPP protocols to create the connection. Configure
the connection according to the configuration of the COM port of the remote computer. By
default, the G250/G350 uses PAP authentication. If your network has a RADIUS server,
you can use RADIUS authentication for the PPP connection.
4. Open any standard telnet program on the remote computer.
5. Open a telnet session to the IP address of the Console port on the G250/G350.
6. Configure the serial connection on the remote computer to match the configuration of the
Console port on the G250/G350. The Console settings are the same as the USB port
settings in
Table 2 except for the baud parameter, which uses the highest possible setting.
