If the D channel isn't functioning I doubt those users would be connected
for much longer, but I could be wrong.

Green Red Description
----------------------------------------------------------------------------
OFF OFF The PRI line is disabled. Typically only occurs when the
unit is booting.
OFF ON There is no physical synchronization with the switch.
ON ON The port is physically synchronized with the switch, but D
channel signalling is not up.
ON OFF The line is fully operational.

differently though?
