Problem
Possible Cause
Possible Solution
Terminal will not
make outgoing ISDN
calls
ISDN power sourcing is turned off
Terminal is not Registered with the Network.
Elevation angle is too low for ISDN service
Enable the ISDN power sourcing
from the BGAN LaunchPad or
ISDN web UI page (unless the
ISDN device has a separate power
source).
Check the Properties page in web
UI to make sure the unit is CS
attached.
Refer to page 9 for ISDN service
restrictions.
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 RJ11 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.
Cannot make fax calls
Elevation angle is too low for fax (3.1KHz
audio) service
Refer to page 10 for service
restrictions.
Terminal is connected
to the BGAN network,
but cannot obtain the
requested Quality of
Service
Network temporarily not available
User tried to set up a 256 Kbps streaming
connection.
Retry again. If problem persists,
contact your service provider.
The Inmarsat Network only
supports 256K for Class 10 > 45
degree look angle and 128K
connections for Class 11 UT’s
Terminal does not
obtain a GPS fix
Terminal’s location limits visibility of 3 or
more GPS satellites.
Move the vehicle / terminal to a
location where there are few
obstructions such as trees or tall
buildings, so that as much as
possible of the sky is visible.
None of the above
solutions resolve the
problem
Terminal may have a hardware or software
fault and needs to be re-booted.
Try resetting factory defaults
Remove power. Wait 30 seconds.
Reconnect the DC power and turn
on the terminal.
Reset to factory defaults: in
release
6.7.1.1 and above,
press and hold
the small recessed blue button near
the RF connector while powering
off.
