T-Com Completes Software-based Optical Node Switchover

T-Com, the fixed line business unit of Deutsche Telekom, performed a software-based optical network node switchover for the first time on 13-December-2003. The switchover, which was part of the SDH2000 project, involved the replacement of an existing Lucent WaveStar Bandwidth Manager in T-Com's Networking Center in Cologne with Lucent's LambdaUnite MultiService Switch.
During the procedure, Lucent and T-Com engineers virtually switched 10,000 transmission paths to the more powerful LambdaUnite network node. Normally, the paths running over a network node are switched manually. A new software tool developed by Lucent OSS Network Operations Software was used to automatically swap all paths in less than three days. The actual hardware swap was completed in just two hours. http://www.lucent.comIn October 2003, Deutsche Telekom's T-Com division launched its new "DDV-M Ethernet100" service, offering speeds of 10, 50 or 100 Mbps for connecting corporate LANs across its national SDH network. The new service, which is transported on T-Com's SDH2000+ backbone, is based on Lucent Technologies' Metropolis AM multiplexer fitted with TransLAN technology for Ethernet over SDH.
