Problem
Terminal will not make
outgoing ISDN calls
Terminal is connected to
the BGAN network, but
cannot obtain the
requested Quality of
Service
Terminal does not obtain
a GPS fix
You hear a loud beep
from the terminal when
you connect an ISDN
device to the ISDN port
None of the above
solutions resolve the
problem
Hughes 9350 BGAN Terminal User Guide
Possible Cause
ISDN power sourcing is turned off
Terminal is not Registered with the
Network and still in antenna pointing
mode. "Bypass antenna pointing" may
be turned off.
Network temporarily not available
User tried to set up a 256 Kbps streaming
connection.
Terminal's location limits visibility of 4 or
more GPS satellites.
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.
Terminal may have a hardware or
software fault, and needs to be re-
booted.
Possible Solution
Enable the ISDN power sourcing
from the BGAN LaunchPad or
ISDN web MMI page (unless the
ISDN device has a separate
power source).
Check Setup page in web MMI
to make sure "Bypass antenna
pointing" is turned ON.
Retry again. If problem persists,
contact your service provider.
The Inmarsat Network only
supports 256 Kbps streaming
connections from UT's that have
an elevation angle greater than
or equal to 45 degrees.
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.
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 DC power adapter.
Wait 30 seconds. Reconnect the
DC power adapter and turn on
the terminal.
