HSD-Xi Terminal System Interfaces

This section briefly describes the external HSD-Xi terminal system interfaces connections to
other systems on the aircraft. For information on interface connections available to aircraft
passengers, see "Installation" on page 3-1.
A. Forward IDs
Forward IDs identify the terminal to the Inmarsat Network.
The 24-bit Forward ID strap pins on the ARINC 600 connector form part of the Inmarsat
Serial Number (ISN). The ISN consists of the type approval number and the Forward ID.
Each Forward ID is associated with Inmarsat Mobile Numbers that a user on the ground
dials to reach the terminal on the aircraft. There is a unique Inmarsat Mobile Number for
each of the service types.
B. Discrete Outputs
The discrete outputs indicate the HSD-Xi terminal status.

Discrete Outputs

MP10 A Power
MP10C HSD-Xi Fail
MP10 B - Channel Available This output is illuminated when the HSD-Xi is
C. Front Panel LEDs
These fault conditions illuminate the LED on the front panel of the HSD-Xi:

This output is illuminated if the unit has power. It
flashes if the HSD-Xi has an active call.
This output is illuminated if the HSD-Xi has a fault.
registered and attached to a network operating in
GAN or BGAN mode, or if the HSD terminal has
allocated power to the HSD-Xi.
