UHP TDM/TDMA Hub has a high-availability modular design, based on principles of distributed computing. 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-280 router. Depending on the software license activated, 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 multiple 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.
The Network Management System runs on a Linux server. It is separate from the Hub, so it’s failure wouldn’t bring down the network.
