Global Wave of Network Transformation
Few Examples…..
BT：Ongoing transformation from “telecom operator” to “Global IT and Network
Service Provider”. Industry’s most ambitious 21CN Network Migration underway.
FT：To be “an integrated information provider and globally leading telecom
network solution provider”.
DT：Provide modernized IT and Communication service including fixed network,
wireless service, internet and complicated telecommunication solution and be “a
leading service provider globally”.
KPN : Implementing complete transformation by introducing new service model and
rationalizing portfolios and platforms, reduce costs and become the “most efficient
operator”. ALL-IP” network transformation to be key enabler for new strategy
China Telecom： By the integration of multi-network, multi-terminal and multi-business
as well as the extension of value chain, to transform from traditional basic network
carrier to “integrated information service provider”.
AT&T：From a local telecom network operator to become the largest communication
and entertainment service provider in the world. To be an one-stop company
providing the next generation products and services.

 All functional elements can reside within a single HW rack, frame or even boards
 System capacity can be linearly and smoothly expanded by simply adding extra modules
 Centralized and Distributed Configuration schemes can satisfy the requirement of small
capacity centralized early stage deployment/trial to a large scale massive network roll-out.
