Make sure that the front and rear cards are pushed fully home, and that
the rack enclosure is powered ON.
Ensure that the Bridge/Router Module is powered on and that the
POWER LED is lit. Check the connections at both ends of the ISDN cable.
Check that the ISDN port is configured using the CO
PO
command. See
the
AccessBuilder ISDN Access Router Software Reference
guide for more
information about this command. If the LED still fails to light, check the
ISDN service by connecting the ISDN port to an alternative ISDN socket. If
all of these options fail, contact your ISDN service provider.
During normal operation the remaining unit LEDs should light and
extinguish depending on the action being taken. If the LEDs fail to light
in accordance with their function then contact your supplying 3Com
reseller for advice.
Check the connections between the Bridge/Router Module, the LAN
and the ISDN line. Check that the number you are dialling is correct
and that it is connected to a remote device. Check that the remote
device is configured to answer incoming calls.
Check for any loose connections between your LAN, Bridge/Router
Module and the ISDN wall socket. Excessive line noise or interference
may also cause an interruption to the line signals in which case you
should dial the remote unit again. If this problem persists, contact your
3Com reseller for advice.
