systems industry.

 
PROFESSIONAL EXPERIENCE WITH Telegroup International 
July 1997 - September 1998 
With the acquisition of ATMnet by Verio, the vision of a global network ATM based 
network was no longer possible. Verio was totally focused on the deployment of a high 
quality IP only backbone for Internet services within the United States. Mr Lettington 
joined Telegroup, Inc. as Director, Asia Pacific Operations in order to hold the vision 
inaugurated at ATMnet. Telegroup initiated an ATM Project to plan and deploy a global 
multi-service network in order to ensure the company's future viability through expansion

(Asynchronous Transfer Mode) fiber-optic backbone connected at 155Mbps to multiple 
ATMnet dedicated nodes and interconnected to other National Service Providers at 
multiple meet points including a connections at the MAE-West facility at NASA, Ames. 
Plans were developed for a complete twenty-one city US National backbone and 
construction was initiated. Mr. Lettington also served ATMnet as Vice President for 
Marketing while recruiting efforts were underway to hire a senior marketing executive.
