1 Scope
The objective of ETSI Project TIPHON is the specification of interoperability mechanisms and related parameters to
enable multimedia communications (particularly voice) to take place, to a defined quality of service, between Switched
Circuit Networks (SCN) and Internet Protocol (IP) based networks and their associated terminal equipment.
The present document presents an overview of the architecture, protocols, QoS and security concepts for the
interworking between TIPHON and IPCablecom systems. It introduces a possible framework for convergence between
TIPHON and IPCablecom.
Annexes A and B give a general overview of IPCablecom and TIPHON.
Annex C addresses architectural issues for interworking between TIPHON and IPCablecom systems.
Annex D provides information on the protocol aspects relating to TIPHON and IPCablecom system interworking.
Annex E examines TIPHON and IPCablecom QoS Policies, architectures and the control of network resources
Annex F reviews TIPHON and IPCablecom security policies and describes the results of a threat analysis.
