UHP TDM/TDMA HTS Hub has a high-availability modular design, based on principles of distributed computing. The Software-Defined Architecture pioneered by UHP Networks is at the core of the Hub design. The Hub is composed of Universal Controllers (UC), interconnected with Gigabit Ethernet links on the data side and with IF splitter/ combiner on the IF side. Each UC is implemented with a single UHP-200 module and has two IF interfaces and two Gigabit Ethernet interfaces. Depending on the software license installed, a specific UC can operate as Outroute Controller (OC) generating a single Outroute TDM (DVB) carrier, Multi-Carrier (MCD) Inroute Controller (IC) capable of receiving up to 4 TDMA carriers, SCPC DAMA transmitter or receiver. UC may have no specific license installed; in this case it serves as a standby resource in the UHP Smart Redundancy scheme.

A single 1RU unit UHP-240 houses two UC and can implement up to two OC and up to two MCD-IC. Extra Outroutes and Inroutes can be added by growing the number of UC with appropriate licenses. The Hub can support any redundancy scheme for any of its elements, and also geographical redundancy for multiples Hubs.

The Network Management System (NMS) runs on a Linux server. It is separate from the Hub, so it’s failure would not bring down the VSAT network. While the NMS optional in a basic Hub, it is required in the high-end Hub designed to control a network operating over High- Throughput Satellite (HTS) with multiple spot beams.
