Another approach to increase the reliability of operational networks is to add a second transmission line based on another technology, for example Audio over IP. The FlexDSR02+ and FlexDSR04+ both offer the possibility to receive a stream via satellite or IP, easily adding an IP backup to an existing satellite transmission system.


Device redundancy (1 + 1) for Audio over Satellite

Further resilience can be achieved by adding redundancy in the transmission chain. Either redundant power supplies (for the IP-8e audio encoder), or redundant encoders and modulators, with the incorporation of a 1 + 1 switch.
