• Three LRU’s make up this System
• An 8 MCU SRT-2100B SATCOM receiver / transmitter weighing only 13.1 kg.
• Provides three classic Aero H, H+, or I channels for voice, facsimile and low-speed PC data over the entire surface of the earth, except for polar regions.
• High-integrity communications for aircraft crew and cabin passengers with ICAO safety services compliance such as routine and emergency ATC/AOC communications.
• Four integral DTMF analog ports and multichannel digital telephone bus (CEPT-E1) for maximum flexibility, with or without a cabin telephone distribution system.
• Capable of interfacing with any Inmarsat-approved high-gain antenna system.
• 45 Watt high power amplifier output simultaneously supports all Aero and two Swift64 channels or two SwiftBroadband channels.
• Enables up to two simultaneous channels of Swift64 or SwiftBroadband service using optional companion HST-2110B high-speed data SATCOM transceivers.
• A 2 MCU HST-2110B equipped with ISDN, ISDN over Ethernet, Ethernet and RS-232 for maximum operator flexibility.
• And a small HCM-2100B Identity Module.

The Collins SRT-2100B is a compact lightweight and economic satellite communications offering. The SRT-2100B incorporates the traditional functions of the high-power amplifier (HPA), radio frequency unit (RFU) and satellite data unit (SDU) within a single 8 MCU package. It operates multi-channel voice, facsimile and low-speed PC data capability. The SRT-2100B also enables up to two simultaneous Swift64 or SwiftBroadband channels using its HST-2110B and HCM-2100B companions. Using its ARINC 741 electrical interface, the SRT-2100B interfaces with all industry standard high-gain antenna systems.

The SRT-2100B Satellite Receiver/Transmitter houses the radio frequency unit, satellite data unit and high-power amplifier. Novel management software monitors and controls the power between the Aero and Swift Services to ensure safety services integrity.

The HST-2110B enables Inmarsat's Swift64 service providing bi-directional 64 kbps packet data and up to 432 kbps SwiftBroadband service enabling services such as internet and e-mail access.

The HCM-2100 houses the USIM identity cards which allows the HST to log into the SwiftBroadband network. A single HCM-2100B is all this is required to support up to two HST-2100B USIM cards.

The SRT-2100B operates using the Inmarsat constellation of geosynchronous communications satellites to enable Aero-H, Aero-H+, Swift64 and SwiftBroadband services. Ground earth stations provide links to the public switched telephone network for bidirectional calling, facsimile and data communications.

The SRT-2100B operates with three Aero channel modules. The SRT-2100Bs architecture allows it to operate in the event of a channel module failure, capable of voice, fax and PC data operation, by removing the failed module from the channel module pool and engaging other modules. A single operational module will support essential data communications such as ACARS or AFIS. Additionally, up to two simultaneous channels of Swift64 or SwiftBroadband service can also be operated using the companion HST-2110B.

The Inmarsat network is suitable for air traffic services that enable the SAT-2100B to provide access to FANS services for preferred airspace routing and clearances in oceanic regions.
