UHP TDM/TDMA 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 which case it serves as a standby resource in the UHP Smart RedundancyTM scheme.
