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.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
authentication header: IPSec security protocol that provides message integrity for complete IP packets, including the
IP header
Application-Specific Data: application-specific field in the IPSec header that along with the destination IP address
provides a unique number for each SA
Baseline Privacy Interface Plus (BPI+): security portion of the ITU-T Recommendation J.112 standard that runs on
the MAC layer
ETSI
10 ETSI TR 102 129 V1.1.1 (2003-01)
Certification Authority (CA): trusted organization that accepts certificate applications from entities, authenticates
applications, issues certificates and maintains status information about certificates
Call Agent (CA): part of the CMS that maintains the communication state, and controls the line side of the
communication
Call Management Server (CMS): controls the audio connections
NOTE: Also called a Call Agent in MGCP/SGCP terminology. This is one example of an Application Server.
DiffServ Code Point (DSCP): field in every IP packet that identifies the DiffServ per hop behaviour
NOTE: In IP version 4, the Type Of Service (TOS) byte is redefined to be the DSCP. In IP version 6, the traffic
class octet is used as the DSCP.
Hashed Message Authentication Code (HMAC): message authentication algorithm, based on either SHA-1 or MD5
hash and defined in IETF RFC 2104
Internet Key Exchange (IKE): key management mechanism used to negotiate and derive keys for SAs in IPSec
IKE-: IKE with pre-shared keys for authentication
IKE+: notation defined to refer to the use of IKE, which requires digital certificates for authentication
Message Authentication Code (MAC): fixed-length data item that is sent together with a message to ensure integrity,
also known as a MIC
Operational Support System (OSS): back-office software used for configuration, performance, fault, accounting, and
security management
Public Key Infrastructure (PKI): process for issuing public key certificates, which includes standards, certification
authorities, communication between authorities and protocols for managing certification processes
quintet: UMTS authentication vector
Record Keeping Server (RKS): device which collects and correlates the various event messages
Signalling Gateway (SG): signalling agent that receives/sends SCN native signalling at the edge of the IP network
NOTE: In particular the SS7 SG function translates variants ISUP and TCAP in an SS7-Internet Gateway to a
common version of ISUP and TCAP.
Session Initiation Protocol (SIP): application-layer control (signalling) protocol for creating, modifying, and
terminating sessions with one or more participants
Signalling System number 7 (SS7): architecture and set of protocols for performing out-of-band call signalling with a
telephone network
triplet: GSM authentication vector
Transaction Capabilities Application Protocol (TCAP): protocol within the SS7 stack that is used for performing
remote database transactions with a Signalling Control Point
Ticket Granting Server (TGS): sub-system of the KDC used to grant Kerberos tickets
