HX200 Router

High-performance HX Satellite Router for specialized markets


The HX200 is a high-performance satellite router designed to provide carrier-grade IP services using dynamically assigned high- bandwidth satellite IP connectivity. The HX200 satellite router provides flexible Quality of Service (QoS) features that can be tailored to the network applications at each individual remote router, such as Adaptive Constant Bit Rate (CBR) bandwidth assignment to deliver high-quality, low jitter bandwidth for real-time traffic such as Voice over IP (VoIP) or videoconferencing. With integrated IP features including RIPv1, RIPv2, BGP, DHCP, NAT/PAT, and DNS Server/Relay functionality, together with a high-performance satellite modem, the HX200 is a full-featured IP Router with an integrated high-performance satellite router. The HX200 enables high- performance IP connectivity for a variety of applications including cellular backhaul, MPLS extension services, virtual leased line, mobile services and other high-bandwidth solutions.

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/DVB-S2 outbound carrier and transmit rates up to 9.6 Mbps, the HX200 provides the high throughput needed for high QoS networking and meets the demands of specialized applications.

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.
