Problems with the LAN Interface
Can’t PING any station on the LAN
1. Check the LAN LED on the front panel of your Prestige. If it is on,
then the link is up. If it is off, then check the cables connecting your
Prestige to your LAN.
2. The type of Ethernet interface that you have configured in menu 3.1.
Verify that you are using the same (AUI or 10BaseT) as configured
in this menu.
3. Verify with your network administrator that the IP address and the
IP subnet mask configured in menu 3.2 are valid for that LAN.
4. Check the physical Ethernet cable, and make sure the connections
on the Prestige and also to the hub are secure.
Problems Connecting to a Remote Node or ISP
1. Check menu 24.1 to verify the ISDN status. If it indicates down
then refer to the section on the ISDN line problems.

see some messages printed onto the screen. The messages will
show you whether the call has been connected or not. If the call is
not connected, verify the following parameters in menu 11:
Pri(mary) Phone #, Sec(ondary) Phone #, and Transfer Rate.
3. If the call is connected, but the call still terminates, then there may
be some kind of negotiation problem. Verify the following
parameters in menu 11: My Login, My Password, Route, IP LAN
Addr. Also verify your IP address in menu 3.2.
