Most interviewees stated that

reduced operational cost is

the most critical factor

Other main drivers for NGN

deployment are availablenew services and scalability

Conclusion


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
