A. Basic Troubleshooting for the network mode HSD
This section provides basic fault checks for the network mode HSD.
• If the Ocean Region registration fails, make sure that the same LES access code is
configured for all components of the system.
• If the HSD-Xi terminal does not transmit calls, make sure that the system configuration
and I/O configuration strapping is correct.
• If the Fault LED illuminates, check the HPA status and Forward ID and SDI strapping.
• If the network mode HSD does not communicate with the aircraft avionics, make sure
that the multi-control and BITE wiring is correct.
• If you cannot make a Swift64 call with the HSD terminal, activate report 38 and verify
the power request value, and verify that RF coax connections in the transmit path to
the DLNA are properly installed.
• If the network mode HSD drops calls when multiple calls are in progress, verify that
the HPA to antenna cable loss value is accurate. Measure again the cable loss values
from the HSD-Xi to the network mode HSD and from the HPA to the antenna.
Reconfigure the cable loss values if necessary.
• If the SBB service is not working, check the Subscriber Identity Module (SIM), Access
Point Name (APN) and the Inmarsat Account.
• During satellite re-clocking, SBB and Classic services may not be available on the
same satellite at a given time. If this occurs, make sure the Classic service is turned
off to access SBB services. See Enabling and Disabling the Classic Channel Card.
NOTE: For information about SBB, or on how to configure Swift64 or SBB services, or
for information about maintenance and monitoring of the network mode HSD, see
