Operators are struggling to manage their aging infrastructure, much of which has exceeded its intended life span and has become a serious operational strain. For years, operators had few architectural options for network modernization. Fortunately, circuit emulation (CEM) has emerged as a means of circuit-to-packet migration, though many operators may not be aware of its scalability or its benefits yet. This webinar will provide a practical tutorial on how CEM can be used for SONET/SDH migration today. In addition to the technical discussion, Verizon's Director of Optical Transport Network Architecture, Design and Planning, Glenn Wellbrock, will detail the operator's own network transformation from legacy SONET/SDH to IP.

Topics covered will include:

  • What are the largest pain points as operators struggle to maintain their legacy SONET/SDH networks?
  • What is circuit emulation and how can the technology be applied to the "SONET problem"?
  • Why did Verizon choose a CEM and IP/MPLS architecture and how are they implementing it today?
  • What is a practical blueprint for operators to follow as they move from TDM to IP networks?
