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

Map the underlying service into PWs – no aggregated signals inside of PWs

TDM Endpoint packetized using CESoP, SAToP or CEP

A-Z Provisioned Pseudowire from Edge to Edge

No intermediate Switching/Grooming Configuration needed per Service

Huge Space and power savings: Get rid of DCS & ADMs

Easy to operationalize - MPLS technology with Dynamic Control plane

Independent Packet Transport Layer
