SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL

Aspire-200

The eNfusion® Communication Convergence Unit (CCU) extends the capabilities of the Aspire system with

additional user connections and features for the aircraft cabin. For more information about the CCU, see

"Introduction to the Cabin Network" on page 2-6, "eNfusion® CCU Interfaces" on page 2-7, and the CCU

Network Administrator's Guide, MN-1233-10054.

The eNfusion® CNX-200 Network Accelerator Series 2 product provides advanced routing functions for the

aircraft cabin. With an accelerator installed at the ground station, the CNX-200 can improve data transfer

rate of the satellite communication system by up to 400 percent. For more information about the CNX-200,

see "Introduction to the Cabin Network" on page 2-6, "eNfusion® CNX-200 Interfaces" on page 2-8, and the

CNX Series 2 Network Administrator's guide, MN-1110-50348.

High data rate (HDR) software is available as an upgrade to the Aspire-200 kit. You can install the

HDR software to enhance Inmarsat L-band services. For HGA installations, the upgrade results in

up to 650 kbps per SBB channel compared to the previous maximum data rate of up to 432 kbps.

For IGA installations, the enhanced system can provide up to 450 kbps compared to the previous

maximum of 333 kbps. The HDR software uses long burst inter-leaver technology to enable the

Aspire-200 system to transmit through helicopter rotors. It also improves system operation in less

than ideal conditions (low look angle, operating in an area where there are interferers).

The CNX-250 Cabin Gateway

is a single LRU designed to act as the communications hub for all aircraft

voice and data services. It includes data routing, Wi-Fi, and 3G/4F cellular. For more information about the

CNX-250, see "Introduction to the Cabin Network" on page 2-6, and the CNX-250 Administration Guide,

23-15-19.

The

CNX-900 is a revolutionary approach to cabin voice and data communications management. Through

the GoDirect advanced user manager, you are provided with access to all passenger usage and can control

device connectivity with just a few steps. It supports redundancy, acceleration and compression, and provide

access to the Honeywell suite of GoDirect services. For more information about the CNX-900, see

"Introduction to the Cabin Network" on page 2-6, and the CNX-900 Installation Manual, 23-15-88.
