SIST-TS TS 101 324 V2.1.1:2004 is the SIST version of ETSI TS 101 324 Version 2.1.1, a Technical Specification for Telecommunications and Internet Protocol Harmonization Over Networks (TIPHON) numbering. It specifies naming, numbering, and addressing for TIPHON-compliant networks when they interwork with Switched Circuit Network (SCN) environments in four call scenarios.

What does SIST-TS TS 101 324 V2.1.1:2004 specify?

SIST-TS TS 101 324 V2.1.1:2004 specifies the naming, numbering, and addressing scheme, plus the related network functionality, needed for TIPHON-compliant networks. It covers calls from IP to SCN, SCN to IP, SCN to IP to SCN, and IP to SCN to IP, with SCN used in both public and private settings.

The document is organized into:

• Scope
• References
• Definitions and abbreviations
• Naming scheme for identification of users and terminals within TIPHON compliant networks
• Functionality required within the TIPHON compliant network
• Bibliography
• History

What are the key requirements of SIST-TS TS 101 324 V2.1.1:2004?

SIST-TS TS 101 324 V2.1.1:2004 focuses on how TIPHON networks identify users and terminals, how they pass numbers to SCNs, and how they handle calling line identity, portability, and special numbers. In practice, this is the part that tells implementers what has to work at the network edge and inside the TIPHON network.

Naming scheme inside the network

Clause 4 requires at least one internal naming scheme that uses only decimal digits and supports either one global system or interoperable local systems. For public networks, the names must be globally unique and must allow single-stage dialling. The scheme must also leave room for mobility, roaming, and portability, which matters when users move or keep their numbers while changing service or location.

Number format at the SCN interface

Clause 4.2 says that numbers passed to and from public SCNs shall conform to ITU-T Recommendation E.164. For private TIPHON networks, numbers passed to and from private SCNs shall conform to ETS 300 189 or ISO/IEC 11571, while direct links to public SCNs still use E.164. This is the practical interworking rule for network gateways and numbering translation.

General network behaviour

Clause 5 requires TIPHON networks to accept the international format of the called party’s E.164 number. They may also accept other E.164 forms used in the local country and private number forms where relevant. The same clause requires that user-requested presentation restriction for Calling Line Identity (CLI) be carried unchanged, and that carrier selection and number portability functions be supported where required by the relevant authority.

Scenario 1, IP to SCN

For Scenario 1, the calling party must be able to identify the called party on the SCN by E.164 number, or by the SCN’s own number in a private network case. TIPHON networks shall also provide a CLI for the calling user when required, even if presentation restriction has been invoked. The clause also requires support for prefixes and special service numbers such as emergency numbers, which matters for call completion and service access.

Scenario 2, SCN to IP

For Scenario 2, TIPHON networks shall respect any CLI restriction received from the SCN. Where service provider portability is required, the network shall support it. This affects how ingress gateways and related services handle privacy and number portability on incoming calls.

Scenario 3 and Scenario 4

For Scenario 3, the network shall convey the CLI, the associated signalling information from the originating SCN, and the digits of the called party number needed to complete the call. The note explains that routing in the IP network is based on the originating SCN and on number blocks that point to the correct egress SCN. Scenario 4 has no extra requirements beyond Scenarios 1 and 2.

What terms does SIST-TS TS 101 324 V2.1.1:2004 define?

• Address - A string that identifies the specific termination point of a connection in a public network, or in interconnected private networks where applicable.
• Dialling plan - The method for using a numbering plan, including prefixes, suffixes, and other information needed to complete the call.
• Gatekeeper - An H.323 entity that provides address translation and access control for terminals, gateways, and MCUs.
• Gateway - An H.323 endpoint that provides real-time two-way communication between an IP-based network and an SCN.
• Number portability - The ability to change service provider, location, or service while keeping the same number.
• TIPHON compliant network - A network that meets the mandatory TIPHON requirements documents named in the standard.
• CLI - Calling Line Identity, used for identification of the calling party.
• SCN - Switched Circuit Network.

Who uses SIST-TS TS 101 324 V2.1.1:2004?

SIST-TS TS 101 324 V2.1.1:2004 is used by telecom network operators, VoIP providers, equipment makers, and integrators that build or manage TIPHON interworking. It is also relevant to gatekeeper and gateway implementers, because the document sets the numbering and identity handling expected at the network boundary.

Quality teams, service planners, and buyers use it when they need to check whether a product or network can pass numbers, CLI, and portability information correctly between IP and SCN environments. Regulatory and service-design teams use it when carrier selection, emergency numbers, or portability rules have to be supported.

What changed in SIST-TS TS 101 324 V2.1.1:2004 from the previous edition?

The document history lists earlier publications V1.1.6 and V1.2.5, followed by V2.1.1. The page identifies SIST-TS TS 101 324 V2.1.1:2004 as identical to TS 101 324 Version 2.1.1.

Which standards are used with SIST-TS TS 101 324 V2.1.1:2004?

• ITU-T Recommendation E.164 - Supplies the public international numbering plan used for called numbers and SCN interface numbering.
• ITU-T Recommendation H.323 - Provides the gatekeeper, gateway, and MCU concepts used in the definitions.
• ETS 300 189 - Provides private telecommunication network addressing used for private SCN interworking.
• ISO/IEC 11571 - Provides private integrated services network addressing used for private SCN interworking.
• TR 101 300 - Defines SCN in the TIPHON context.
• TR 101 306 - Gives TIPHON service interoperability requirements for Scenario 1.
• TR 101 307 - Gives TIPHON service interoperability requirements for Phase 2.
• TR 101 308 - Gives TIPHON service interoperability requirements for Scenarios 1, 2, and 3.
• TR 101 338 - Covers roaming techniques applicable to TIPHON mobility services.

What does the SIST-TS TS 101 324 V2.1.1:2004 document contain?

The document contains requirement clauses rather than procedures or test methods. Clause 4 sets out the internal naming scheme and the number formats to use at SCN interfaces, while Clause 5 gives the functional requirements for all scenarios and then separates them by Scenario 1 through Scenario 4.

It also contains definitions, abbreviations, notes on numbering practice, and references that support implementation. The bibliography points to TR 101 309 as supporting material, and the history records the publication versions.

1 Scope
The present document specifies the naming, numbering, and addressing scheme and related functionality required within
TIPHON compliant networks for calls:
- from Internet Protocol (IP) based terminals to terminals in a Switched Circuit Network (SCN) (TIPHON
scenario 1);
- from terminals in an SCN to IP based terminals (TIPHON scenario 2);
- from a terminal in an SCN through an IP based network and back to a terminal in an SCN (TIPHON scenario 3);
and
- from a terminal in an IP based network through an SCN and back to a terminal in an IP based network (TIPHON
scenario 4).
The objective of the present document is to ensure satisfactory interworking between TIPHON compliant networks and
SCNs. An SCN may be a public network or a private network.
These requirements affect terminal equipment and equipment that performs the roles of gatekeeper and gateway, and the
calling procedure for the end user.
Where the text indicates the status of a requirement (i.e. as strict command or prohibition, as authorization leaving
freedom, or as a capability or possibility), this may modify the nature of a requirement within a referenced standard used
to provide the capability.
