Layer 1 Status:
DEACTIVATED
This indicates that the BRI interface is not seeing a signal
on the line. There are five possibilities.
The BRI interface is shut down. Either check the
configuration for the command shutdown under the
BRI interface, or look for an administratively down
indication from the show interface command. Use the
configuration utility, and enter no shutdown under the
BRI interface. Type the command clear interface bri
at the exec prompt to make sure that the BRI interface
is restarted.
Cabling is bad. Make sure that you use a
straight-through RJ-45 cable. To check the cable, hold
the RJ-45 cable ends side by side. If the pins are in the
same order, the cable is straight-through. If the order
of the pins is reversed, the cable is rolled. Verify that
the correct cable is in place and is working.
