Highly available data transmission for broadcasting stations
An Add-Drop multiplexer in the centre receives the different signals for transmission between the studio and the transmitter stations. For this purpose Ethernet/IP or X.21 interfaces are employed for FM data and a V.24 interface for supplementary data e.g. RDS data.
For DAB, DAB+, DVB-T, DVB-H, DRM and HD the corresponding interfaces are activated with the desired bandwidth in the multiplexer (G.703 or Ethernet/IP).
The bundled signal and data (multiplex) are transported via copper lines, optical fibres or radio relay systems to the broadcasting stations from where they are transferred to the transmitter. At the same time network management and alarm data are transported back to the centre via the same communication channel.
A very high availability is achieved due to various protection mechanisms at the network and network element layers.
UMUX is a Multi-Service Access system that can provide a range of applications for dedicated network operators. Besides the Ethernet/IP interfaces all legacy interfaces are supported. Manifold network interfaces are integrated as well.
