Market challenges
Early NGN promises
Early promises of NGN:
The 90s: Aggressive Growth
•
•
•
•
„VoIP is the ultimate cost saver for
long-distance and international calls“
Market liberalization
Explosion of Internet access
High market capitalization
Dot.com driven technical hype
“Discard your old network and build a new
all-IP network and you will be better off”
Since
Since 2001:
2001: Economic
Economic Slow
Slow Down
Down
NGN promises in the past were:
• High debt levels
• Less-than-expected growth
• Market driven investments
„Declining prices for long-distance calls
don‘t leave much room for earnings“
Since
Since 2003:
2003: Maximizing
Maximizing ROA
ROA
NGN Realities today are:
• Secure current investment
• Step- by-Step investment
“NGN has to guarantee investment
protection of existing infrastructure”
Qualitative growth replaces quantitative growth!

TDM to NGN evolution
Requirements for flexible and cost efficient NGN migration
Ideally the TDM to NGN migration
should
OPEX
CAPEX
US$ per year
Revenues
§ Support full legacy feature set
Your
profit !
§ Allow the introduction of new,
revenue-generating services
§ Yield low technology
introduction costs
§ Result in lower Operational
Expenditures
Legacy TDM
network
After migration to
NGN
§ Increase Return on Assets
* Total Cost of Ownership
TDM to NGN migration should focus on maximizing Return on
Assets by reducing TCO* and increasing revenues
