HSD Modes and Configuration Descriptions
A. General
This section describes the system mode and configuration variations for the HSD
High-Speed-Data SATCOM Transceiver installations.
High-Speed-Data SATCOM Transceiver installations.
B. Overview
HSD transceivers install in a variety of customized configuration modes. HSD transceivers
may be installed as Stand-Alone systems or as Non-Stand-Alone units installed within
existing SATCOM systems. Four different system configuration modes are possible:

(a) Dual-Channel Card HSD Transceivers
In dual-channel card HSD transceivers, both 64 kbps channels work either
independently or as a bonded 128 kbps data-link to the Inmarsat
Communications Network.

(c) Multi-Channel Configurations
Stand-Alone HSD-128 transceivers in Multi-Channel installations support two 64
kbps channels that work either independently or as a bonded 128 kbps data-link
to the Inmarsat Communications Network as well as an additional 64 kbps
channel per HSD-X installed in the system.
