Objectives
• To provide insight from the platform
supplier perspective
• To share experiences we’ve seen and been
a part of regarding this network scenario
• To help guide developers out of the field
and into the lab…There will be no sales if
there is no product

Word of the Day
Flexibility - Flex`i`bil´i`ty
1. the quality of being adaptable or variable;
2. the ability to change or be changed to fit
changed circumstances
3. the ease with which a system or
component can be modified for use in
applications or environments other than
those for which it was specifically designed
Flexibility…Let me count the ways
•
•
•
•
•
Application(s) – Fixed & mobile, voice & signaling
Size – <100 Channels to thousands
Signaling - IP (SIP & H.323) & TDM (SS7/PRI/CAS)
Architecture – IMS, SIP, Service Node
Carrier-class and non-carrier-class – (I know
this goes off topic, but as a developer you
should be able to provide alternative
architectures for an array of customers while
minimizing your costs and their costs.)

It’s more than the technology…Own YOUR
customer…Get footprint and relationship
Conclusion
• For developers, there is no uniform or ideal
architecture being adopted across the board by
service providers, which therefore requires insight
and innovation on your part
• Multi-function platforms can offer substantial
benefits to service providers but ONLY if they truly
meet the needs of the carrier
• As an app developer, your primary concern should
be defining and exceeding your customer(s) needs
while differentiating yourself and minimizing YOUR
costs
