DAB-Modulationsautomatik in SFN-Netzen

TENDER DESCRIPTION

We are looking for a device that monitors the line feed (EDI over IP multicast) and reacts to events and failures in accordance with our requirements as stated in the specifications. The aim is, in the event of communications failure, to continue operating selected transmitters in an SFN. The device shall have at least four inputs and two outputs for the various switching configurations of the line signal circuits. Two inputs are used for the normal EDI signals from the leased lines, and two further inputs are assigned EDI signals via reserve paths that are available on site. Further interfaces for remote and on-site access are provided. This device is called the modulation automation (MA). The estimated scope includes: - 64 modulation automations - 24 splitter pairs (2 controllers per SFN = 48 units) We are looking for a device that monitors the line feed (EDI over IP multicast) and reacts to events and failures in accordance with our requirements as stated in the specifications.
