reduced operational cost is
the most critical factor
Other main drivers for NGN
deployment are availablenew services and scalability

Ideally the TDM to NGN migrationshould
Support full legacy feature set
Allow the introduction of new,revenue-generating services
Yield low technologyintroduction costs
Result in lower OperationalExpenditures
Increase Return on Assets
