Symmetricom and Nokia Siemens Validate IEEE 1588v2 (PTP) over Multiprotocol Label Switching (MPLS) Networks at Carrier Ethernet

  
    
  
  
    
      Symmetricom, Inc. (NASDAQ: SYMM), a worldwide leader in precise time and 
      frequency technologies that accelerate the deployment and enable the 
      management of next generation networks, today announced its TimeProvider™ 
      5000, the industry’s first carrier-class IEEE 
      1588v2 grand master clock, successfully interoperated with Nokia Siemens 
      Networks’ Timing over Packet solution over a 
      Multiprotocol Label Switching (MPLS) Network at the 4th 
      Multi-Vendor Carrier Ethernet World Congress (CEWC) Interoperability 
      Showcase, September 22-26, 2008 in Berlin, Germany organized by EANTC. 
      In April, Nokia Siemens Networks introduced the industry’s 
      first open standard Timing over Packet solution that incorporates the 
      TimeProvider 5000 to synchronize base stations over packet-based 
      Ethernet backhaul networks.
    
    
      “TimeProvider 5000 enables Nokia Siemens 
      Networks’ customers to accelerate their 
      migration from TDM to Ethernet backhaul resulting in cost savings while 
      simultaneously boosting network capacity to handle bandwidth hungry 
      applications like voice, video and music downloads,” 
      commented Mike Vizzi, senior product manager at Symmetricom. “Our 
      success at the Multi-Vendor CEWC Interoperability Showcase demonstrates 
      that running PTP over MPLS Layer 2 networks has moved from ‘proof-of-concept’ 
      to the ‘practical deployment’ 
      stage.”
    
    
      In the Timing over Packet solution, Symmetricom’s 
      TimeProvider 5000 distributes a network reference clock to a large 
      number of PTPv2-enabled NSN base stations. The base station’s 
      ability to synchronize its frequency based on the reference received 
      from the TimeProvider 5000 is critical to maintaining service provider 
      Service Level Agreements (SLAs), minimizing service disruptions and 
      eliminating dropped calls. Timing over Packet is an open and future 
      proof solution based on the IEEE 1588 version 2 standard. It addresses 
      the synchronization requirements of both today as well as forthcoming 
      3GPP Long Term Evolution (LTE) wireless networks. The synchronization of 
      base stations is a critical building block for mobile backhaul networks.
    
    
      “This is the first, complete, live 
      demonstration of Nokia Siemens Network’s 
      proposition for mobile backhaul over Carrier Ethernet, including all 
      elements in the network chain,” commented 
      Dirk Lindemeier, responsible for mobile backhaul solutions at Nokia 
      Siemens Networks. “More remarkably, it is the 
      first time we have demonstrated a complete solution for packet based 
      synchronization working live over a multi-vendor Carrier Ethernet 
      network. We are pleased to have teamed with Symmetricom for the critical 
      synchronization component using their TimeProvider 5000, a carrier-class 
      IEEE 1588v.2 grand master clock.”
    
    
      The live event at IIR’s Carrier Ethernet 
      World Congress included a network of more than 100 leading-edge systems 
      and provided proof-of-concept for network operators who want to migrate 
      and utilize next generation Carrier Ethernet services. A 20-page white 
      paper with detailed findings is available for download at http://www.eantc.com/cewc2008.
