SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
Figure 1–4 and Figure 1–5 illustrate the user interfaces for single-channel HSD
transceiversFigure 1–6 and Figure 1–7 illustrate the user interfaces for dual-channel HSD
transceivers. For clarity, these figures only display Data Services. Voice devices are
supported by direct connection to the HSD using EURO ISDN telephones or by indirect
connection to a router or terminal adapter using two-wire telephone handsets.

(1) Stand-Alone Mode User Interfaces
Dual-channel HSD transceivers support a maximum of two simultaneous instances
of Swift64 Mobile ISDN and/or Mobile Packet Data Services (MPDS) services.
of Swift64 Mobile ISDN and/or Mobile Packet Data Services (MPDS) services.
(2) Collins Cooperative Mode User Interfaces
In Cooperative Mode installations, the HSD system provides one channel of Swift64
data service and Aero H/H+ call capability. Swift64 and Aero H/H+ calls are
simultaneously possible providing the following system conditions are met:

simultaneously possible providing the following system conditions are met:
•
If a Swift64 call is in process and an Aero H/H+ call is attempted, either incoming
or outgoing, the Aero H/H+ call is allowed to proceed providing that there is
sufficient HPA power available to process all calls.

If any Aero H/H+ calls are in process, a Swift64 call is allowed providing that there
is sufficient HPA power available to process both the Swift64 and Aero H/H+ calls.

(3) Honeywell Combined Mode User Interfaces
In single-channel transceivers in Combined Mode installations, the HSD system
provides one channel of Swift64 data service and Aero H/H+ call capability. In
dual-channel transceivers in Combined Mode installations, the HSD system provides
two channels of Swift64 data service and Aero H/H+ call capability. Swift64 and Aero
H/H+ calls are simultaneously possible providing the following system conditions are
met:

If both call types are in process, and system resources become limited due to
dropping antenna gain, then Aero H/H+ calls will maintain priority.

(4) Selective Mode User Interfaces
In Selective Mode operation, dual-channel HSD transceivers support a maximum of
two simultaneous instances of Swift64 Mobile ISDN and/or MPDS services.

(5) Multi-Channel Configurations
The HSD Multi-Channel configuration combines a dual-channel, Stand-Alone Mode
HSD-128 Transceiver with one or more single-channel HSD-X Transceivers to add
additional channels to the system.

MPDS connections demand more power and may reduce channel availability. AMBE
connections demand less power and may increase channel availability.
