Troubleshooting

Problems With the ISDN Line

If you are having problems making a connection through the ISDN line,

try performing a Loopback Test (in the console program choose

System Maintenance, Diagnostic, Loopback Test). If the loopback

test succeeds then your physical connection to your phone company is

ok and the problem probably lies in your ISDN settings (located in the

console program under Interface Configuration, ISDN). Alternatively,

the problem could be with the router or computer you are trying to call.

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.  Make sure the LAN is enabled in the Interface Configuration,

LAN submenu of the console program.

3.  Verify with your network administrator that the IP address and the

IP subnet mask configured in the Network Configuration, IP

Configuration, IP Stack Configuration, LANsubmenu of the

console program are valid for that LAN.

4.  Check the physical Ethernet cable, and make sure the connections

on the router and the hub or station are secure.

5.  Check to make sure an end station IS NOT connected to the Uplink

port or that a hub IS connected to the Uplink port using straight-

through cables.
