What – CES
Why
Traditional x-haul technologies unable to maintain pace with the exponential growth in Access
Legacy voice and TDM services to co-exist with NG-services
Where – Access to backhaul, transition to a packetized infrastructure
How – Efficiently carry TDM signals on a packet switched network, while maintaining accurate synchronization information for these circuits
Transporting TDM over Packet A Different Approach
