Possible Cause
The MSN programmed into the ISDN device
does not match the MSN programmed into the
terminal
ISDN power sourcing is turned off
Terminal is not Registered with the Network.
The ISDN device is trying to draw too much
power from the satellite terminal's ISDN
interface
The device you are connecting is not an ISDN

are accidentally connecting to the ISDN port.
Make sure that you don't have both RJ-11 and
ISDN handsets connected at the same time.
