SatLink Hub Family Efficiency | Throughput | Scalability | Reliability Standards Compliant TDM/TDMA Satellite Networks
SatLink Hub Family SatLink Hubs provide the high-performance modems, IP gateway, management and control functions for all STM VSAT networks. They implement a TDM/TDMA network in accord with DVB-S2 & DVB-RCS2 standards, offering Bandwidth-on-Demand, ACM, and QoS on all carriers, while delivering excellent efficiency, throughput, scalability, and reliability. The Hub design employs STM’s Open Hub Architecture using a common set of modules that ease growth and re-configuration.

SatLink Hub Family SatLink Open Hub Architecture SatLink Hub design uses STM’s Open Hub Architecture with commercial off-the-shelf modules mounted in standard racks with high-capacity Gigabit Ethernet interconnects. This eases growth and reconfiguration, while also allowing for integration of 3rd party products for value -added features. A full range of SatLink Hub configurations are offered from small portable Hubs to carrier-class Hubs with 99.999% uptime. All configurations use a common set of modules.
