The TANGRAM platform can be used in a central or distributed headend architecture and provides the following processing functions in a central location: DVB-IP gateway for DVB-S/S2/ -C / -T / -T2, descrambling, remultiplexing, scrambling, PSI/SI processing and modulation.
In a decentralized architecture with regional hubs, the modulation is done in the hub site and the aggregated digital TV streams are transported via an IP network and are terminated in Edge-QAMs, -COFDMs*, -PALs and -FMs for remodulation and transmission in HFC networks.
The TANGRAM chassis can be equipped optionally with two load sharing redundant power supplies (DC or AC) and contains high-performance monitored fans for cooling. Modules, fans and power supplies are hot swappable.
