HX280 Terminal

High-performance IP satellite router with enhanced security

The HX280 is a commercial off-the-shelf (COTS), high-performance satellite router that builds on the successful HX260 mesh/star product, enabling carrier-grade broadband Internet Protocol (IP) services with enhanced security and on-the-move (OTM) capabilities. Ideal for commercial and government/military applications, the HX280 has integrated AES256-based Federal Information Processing Standards (FIPS) 140-2 cryptographic security (optional; subject to local government approval). It also supports the HX System Enhanced Signaling Security feature, which protects all data, management, and signaling traffic over the satellite network. These security enhancements build on the high Quality of Service (QoS) features of the HX System, including adaptive, Constant Bit Rate (CBR) bandwidth assignment that enables efficient delivery of low jitter, real-time applications, such as Voice over IP (VoIP) and videoconferencing.

With integrated IP features including RIPv1, RIPv2, BGP, DHCP, NAT/PAT, and DNS Server/Relay functionality in a compact, high- performance router package, the HX280 is the ideal platform to configure any combination of mesh and star topologies for highly secure, broadband IP networks. In particular, simultaneous mesh and star operation of the HX280 yields the most bandwidth-efficient solution possible when combining VoIP services on a per-call basis with continuous, high-speed data services such as Internet access.

Target Markets

  • GSM backhaul, SCPC/MCPC replacement links
  • MPLS extension services
  • Embassy and government networks
  • Air traffic control
  • Virtual Private Networks (VPN), leased-line services

HX System Architecture

The HX System is fully compliant with the IPoS/DVB-S2 satellite standard, including adaptive coding and modulation (ACM), the world’s leading standard approved by TIA, ETSI, and ITU. Its architecture consists of a central HX Gateway connecting to multiple HX remote terminals. The outbound channel from the central gateway is continuously received by every HX remote terminal in the system—and this reception is independent of the mesh connection status of any given terminal. The connectivity from a remote terminal to either the HX Gateway or other HX280 terminals is via TDMA links. Efficiency and flexibility in utilizing satellite bandwidth are at the core of the HX280 design. Each TDMA link, whether in star or mesh mode, can be configured to provide a QoS tailored to the requirements of each link. This includes such capabilities as defining a minimum Committed Information Rate (CIR) and maximum rate, thereby enabling service providers to develop services tailored to customer-specific requirements. In addition, the HX System bandwidth allocation scheme uses an Aloha channel for initial traffic requests (and only initial traffic requests), which means that terminals are able to release all TDMA channel assignments when they are idle. This frees up unused bandwidth and allows operators to make more efficient use of space segment resources.
