Prestige 480 Dual BRI ISDN Router
12-2 Telnet Configuration
Figure 12-1 Telnet Configuration on a TCP/IP Network
12.2 Telnet Under SUA
When Single User Account (SUA) is enabled and an inside server is specified, telnet connections from the
outside will be forwarded to the inside server. So to configure the Prestige via telnet from the outside, you
must first telnet to the inside server, and then telnet from the server to the Prestige using its inside LAN IP
address. If no insider server is specified, telnetting to the SUA’s IP address will connect to the Prestige
directly.
12.3 Telnet Capabilities
12.3.1 Single Administrator
To prevent confusion and discrepancy on the configuration, your Prestige only allows one administrator to
log in at any time. Your Prestige also gives priority to the console port over telnet. If you have already
connected to your Prestige via telnet, you will be logged out if another user logs in to the Prestige via the
console port.
12.3.2 System Timeout
There is a system timeout of 5 minutes (300 seconds) for either the console port or telnet. Your Prestige will
automatically log you out if you do nothing in this timeout period, except when it is continuously updating
the status in Menu 24.1.
