Prestige 480 ISDN Router
10-2 Telnet Configuration
10.2 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.
10.3 Telnet Capabilities
10.3.1 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.
10.3.2 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.
