The HX System provides true IP broadband connectivity via satellite. The HX System is based on a “star” network topology where the outbound channel is DVB-S2 with Adaptive Coding and Modulation (ACM). The return channel of the HX System is FDMA/TDMA using the IPoS standard for broadband over satellite. With a DVB-S/DVBS2 outbound carrier supporting rates up to 121 Mbps and multiple inbound carriers supporting rates up to 3.2 Mbps, the HX System provides the high throughput needed for high QoS networking.

Efficiency and flexibility in utilizing satellite bandwidth are at the core of the HX200 design. Each link can be configured to provide a QoS tailored to the requirements of the remote site. This includes adaptive Committed Information Rate (CIR) and Constant Bit Rate (CBR) services that provide guaranteed bandwidth though optimizing use of the bandwidth during periods of idle or light traffic. Remote sites with less stringent bandwidth requirements or service level agreements can be configured for best effort service, thereby allowing service providers to develop a service tailored to their customers’ specific requirements. In addition, the HX System bandwidth allocation scheme uses Aloha channels for initial bandwidth assignment which results in very efficient use of space segment. This frees up unused bandwidth and allows an operator to make more efficient use of space segment resources.
