Full Description

The present document defines the TIPHON network architecture and the reference configurations that are necessary for:the delivery of telephone calls, which originate and terminate in IP networks;the delivery of telephone calls which originate in an Internet Protocol (IP) network and are delivered toSwitched Circuit Networks (SCN);the delivery of telephone calls which originate in SCNs and are delivered in an IP network; andthe delivery of telephone calls which originate in SCNs, routed through IP networks and delivered to SCN.These four scenarios are part of TIPHON Release 4.

The architecture includes provision of information and facilities which are incidental to the delivery of telephone calls described above. The present document builds upon the concepts embodied in the TIPHON Release 3 network architecture and reference configurations described in TR 101 877 [8]. The present document is applicable to equipment fulfilling the roles of the functional groups identified in TS 101 878 [2]; Terminal functional group, network functional group and Gateway functional group, and also to entities within the IP network that are necessary to support the four scenarios of TIPHON Release 4.
