CBC/Radio-Canada Tests Net Insight's DTM for Media Transport

CBC/Radio-Canada has successfully tested Net Insight’s Dynamic synchronous Transfer Mode (DTM) technology for transporting high-quality video, radio, IP/Ethernet data and VoIP between its facilities in Montreal and Toronto. The trial used a combination of dark fiber and OC-3 capacity between the two cities. Net Insight’s Nimbra One access switches were located at each end. The Nimbra One switches were equipped with modules for Ethernet, E1, DVB-ASI and OC-3. The test equipment used an automated control plane with enhanced GMPLS functionality for load balancing, mesh protection and multicast provisioning. DTM is a circuit-switched technology with strong QoS support. DTM is currently being standardized within ETSI.
