SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
SYSTEM DESCRIPTION
1. Purpose of Equipment
The HSD is a scalable, high-speed-data, satellite communications terminal, which interfaces
with an ARINC 741-compatible antenna subsystem to provide a high-speed data
communication link with the Inmarsat satellite communication network. HSD transceivers are
available in single and dual channel models which can be installed in the following modes of
operation: Stand-Alone Mode, Combined/Selective Mode, and Cooperative Mode.
In Stand-Alone Mode HSD installations, the addition of HSD-X extension transceivers expands
the channel capacity by providing one additional voice or 64 kbps data channel—per HSD-X
to provide a Multi-Channel, high-speed data communication link with the Inmarsat satellite
communication network.
Table 1–1 shows the services that are supported by each HSD terminal.
