DR needs a new distribution network for FM and DAB+ broadcasting. This tender covers the transmission of data from DR Byen to the individual transmitter sites, to be provided as a service.
It includes the lease and operation of a large number of transmission lines, as well as intermediate hardware both in DR Byen and at the transmitter sites, including but not limited to networking equipment, audio codecs and DAB EDI to ETI converters.
A very high level of reliability is required, and redundant transmission lines will be a necessity for a large number of sites. Design proposals are provided in the tender material, but ultimately the design of the system is up to each potential vendor.
It is expected that vendors will need to employ subcontractors in order to provide the required expertise in all areas of the tender, including network technology and broadcast-specific equipment and services.
• delivery of Audio-over-IP (AoIP) multichannel codec equipment for real-time uncompressed audio transmission and transmission of audio services through a new IP/MPLS-based primary distribution network between DR Byen and the 16 main FM-transmitter sites in Denmark;
• transmission of existing RDS and DARC services through the IP/MPLS network comprising main and protection connections to the same 16 FM-transmitters;
• transmission of existing DAB EDI signals for DAB+ audio services through the IP/MPLS network to a number of transmitter sites in DK, for further information see excel sheet;
• delivery of external EDI-> ETI converters with protection switching for the DAB transmitters that are not prepared for EDI input signals;
• real time, low-latency IP/MPLS connections from DR Byen to all the 16 FM-transmitter sites and a number of DAB transmitter sites. The connections for the FM-transmitters must be able to provide very high reliability including error protection and seamless protection of the audio signals, and with simple protection switching for the RDS and DARC signals. The connections to all FM sites and some specified DAB sites must be implemented with full redundancy, preferably with fiber connections in separate routes in the ground all the way to the transmitters;
• a centralized Management and Control (M&C) system for supervision of correct operation of the above equipment and the connections, with current status reporting back to an MCR PC in DR;
• 24/7 operation of the equipment and the IP/MPLS connections according to a specified SLA for the entirety of the contract.
• 64 audio terminals for FM primary distribution applications (2x16 multichannel encoder terminals at DR Byen and 2x16 multichannel decoder terminals at the FM transmitter sites),
• 53 x 2 EDI -> ETI converters with protection switching for adapting EDI signal to the ‘old’ DAB transmitters with ETI-inputs only,
• 2 large Gb/s Ethernet switches with many ports to be installed in DR Byens Server Room 1 and 2, respectively,
