Problems with the LAN Interface
Can't PING any station on the LAN
1.
Check the LAN LED on the front panel of your router. If it is on,
then the link is up. If it is off, then check the cables connecting the
router to your LAN.
2.
Verify with your network administrator that the IP address and the
IP subnet mask configured in menu 3.2 are valid for that LAN.
3.
Check the physical Ethernet cable, and make sure the
connections on the router and 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.
2.
In menu 24.4.5, do a manual call to that Remote Node. You will
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 terminated immediately after a connection is
established, 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.
4.
If you check the error log in menu 24.3.1, this will usually give you
some logs regarding why the call was dropped. If there is nothing
in the log, the call may have been dropped by the remote device
that you dialed in to. Make sure that the configuration parameters
between these two devices are consistent.
