Problem
Possible Cause
Possible Solution
ISDN device does not operate
correctly
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
device. It might be an Ethernet device that you
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.
Only connect an ISDN
device that draws less
than 70mA of current at
40V (equivalent power
2.8W)
Make sure you connect
only ISDN devices to the
ISDN port
Remove one of the
handsets and reboot the
terminal.
None of the above solutions
resolve the problem
Terminal may have a hardware or software fault,
and needs to be re-booted.
Remove power. Wait 30
seconds. Reconnect the
DC power and turn on the
terminal.
