DSB Uses 6KQs For 'Ethernet Backbone' In Trains
Danish state rail operator DSB is using 6KQ Ethernet switches from Garrettcom to give its trains an 'Ethernet backbone'. The 6KQ switches realise VLANs for various internal train systems, providing network connections for in-carriage IP-enabled security and surveillance equipment, infotainment systems and passenger-counting technology. The 6KQ met DSB's need for a compact, cost-effective 10-port Ethernet switch with gigabit bandwidth, in a hardened package with the assurance of EN50155 certification for railway applications. A 6KQ switch is mounted in each carriage and the switches are linked in a bus topology, providing an Ethernet backbone along the length of the train. The switches provide central points in each carriage into which the IP-enabled equipment can be readily connected. The backbone is also connected to a WLAN gateway, responsible for handling the network traffic between the train and the outside world. Network packages are transmitted and received via an an...
