The deployment is supposed to provides a more flexible, cost effective and secure solution than the existing STM-1 microwave systems. As part of its roll-out of DVB-T2, SR decided to move the transport of signals to its main transmission sites to IP technology running on fiber. SR chose Nevion and local partner LOGIC Media to deliver the solution it required.
Nevion TVG425 media nodes now provide DVB-T2 ASI to IP conversion and viceversa, with full dual path redundancy for protection. Nevion VS 906 media nodes provide a similar conversion for AES and E1 to IP. Nevion eMerge IP switches provide IP aggregation and routing for all IP flows, which include two DVB-T2 multiplexes, four FM programs, an ETI data stream for DAB and various E1 channels, as well as IT in-house applications.
The legacy microwave connection remains in place as a back-up solution, if the new fiber connection would fail. For this purpose, the IP signal is converted to STM-1 on a port of the eMerge switches. Markus Kirst, engineer at SR, explains: “Nevion and LOGIC Media have a wealth of experience in IP technology, from simple point-to-point to large distributed networks, so they were the obvious partners for this project.”
Fil Soares, Vice President of Sales Europe at Nevion, concludes: “We are delighted to add SR to our long list of customers who have chosen to deploy IP technology, and we are proud to deliver a solution that met the requirements in collaboration with our partner LOGIC Media.”
