Beskrivelse af udbuddet
The tender covers the following types of 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.
• installation, testing and commissioning of the equipment and the connections.
• 24/7 operation of the equipment and the IP/MPLS connections according to a specified SLA for the entirety of the contract.
The suggested extent of the requested delivery (without options) is:
• 64 audio terminals for FM primary distribution applications (2 x 16 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.
• 2 x 16 small Gb/s Ethernet switches with few ports to be installed at the FM-transmitter sites.
• up to 2 x 54 small Gb/s Ethernet switches with few ports to be installed at the DAB-transmitter sites (the actual number is dependant of the chosen system solution).
• 2 x 16 IP/MPLS unicast capable connections from DR Byen’s Server Room 1 and 2 for audio, RDS and DARC signals to all the FM-transmitters implemented with full redundant routes.
• 2 x 18 IP/MPLS multicast capable connections from DR Byen’s Server Room 1 and 2 for DAB EDI signals to the DAB-transmitters implemented with full redundant routes, of which 12 are shared with FM transmitters on the same site.
• 2 x 43 IP/MPLS multicast capable connections from DR Byen’s Server Room 1 and 2 for DAB EDI signals to all the smaller low-priority DAB-transmitters implemented with full redundant routes connections from DR Byen’s Server Room 1 and 2 at least all the way to the nearest exchange, and a single ‘last mile’ connection to the DAB transmitter site.
• 1 M&C system for control and supervision and monitoring of all audio codecs, EDI->ETI converters and IP/MPLS connections.
• Installation and commissioning of the Equipment, in close collaboration between the Contractor and the Customer. It is recommended that the contractor is cooperating with a Danish speaking system integrator that is able to carry through the system integration and implementation at the transmitter sites.
