TDM Extension over Packet Networks Using Pseudo Wire Service Providers Business Services

Transport legacy TDM services over Ethernet or MPLS-based networks using pseudowire technology in a point-to-point or point-to-multi-point topology.


  • Service providers are still maintaining TDM services and networks
  • Maintaining revenue flow from legacy services and add new IP/Ethernet services
  • Churn reduction by preserving legacy services
  • Broad portfolio of pseudowire solutions: CPEs and Aggregators
  • Flexibility of TDM emulated services: nx64, E1 up to Channelized  STM-4
  • Pseudowire services can be delivered over point to point and point to multi-point topologies
  • Ensure timing synchronization over packet transport
