2 BST (Broadband Satellite Terminal) Network Diagram

3 BST System Capabilities
Inmarsat Compatible SwiftBroadband (Airborne version of BGAN) Voice 2 VoIP channels, wired telephone network toll quality Push-to-talk supervision transmitted in-band Full Duplex capable, each direction independent Uses bandwidth only when talking (background) Video or Other UDP Data 10/100Base-T (UDP) 32 kbps, 64 Kbps, 128 Kbps, 256 Kbps fixed streaming or variable background (selectable) Two Async Serial Data Channels Full Duplex, optional hardware flow control Telemetry & Command (T&C), 38.4 Kbps (default rate) Payload Data, up to Kbps 3

4 BST Security & Redundancy
Inmarsat Encryption Satellite air interface segment commercially encrypted by the Inmarsat network NSA Type-1 encryption on satellite command links BST End to End Encryption AES 256 shared key User selectable for each interface individually User Encrypted Payloads BST delivers externally encrypted payloads transparently Redundant Connection, Ground Station to Inmarsat Direct T1/E1, VPN, Mil Net, VSAT, Internet – Single Hop Satellite (BGAN) backup – Double Hop 4

5 BST Interfaces Toll Quality VoIP Audio, 2 Channels
Transformer Coupled, 150 Ohm or 600 Ohm balanced Input level – 1Vpp to 50Vp-p (ARC-210 compatible) Output level – 1Vpp to 3Vp-p 28V Logic ground for push-to-talk (PTT) in and out Full Duplex capable, each direction independent 10/100Base-T Ethernet (UDP) User data or video, streaming or background RS-422 Async Serial Data Full duplex asynchronous data, up to Kbps (w/optional flow control) RS-232/422 Async Serial Data EIA-232/422, selectable by wiring RS-422 Async Serial Control (Terminal Administration) Configuration and status monitoring of terminal, up to Kbps (w/optional flow control). 5
