The IP Federating Network (IPFN)


An IP ‘

Virtual Private Network

’, with specific Sub Systems
connected to it, interconnecting the Wireless (and fixed) accesses for
Voice and Data and offering levels of Services


The IPFN shall allow
Voice and Data

communication VPNs features to
share INFORMATION

and garantee Security


The IPFN shall offer new Services to the users


The IPFN shall allow
interworking


Different ‘

functionnal

’ sub systems are added


mapped to a scalable hardware configuration


Fully digital, where ‘

Voice is Data




Legacy systems into account
