SIST EN 302 097 V1.2.2:2005 is the Slovenian adoption of ETSI EN 302 097 V1.2.2, a European telecommunications standard for the ISDN User Part (ISUP) of Signalling System No. 7 (SS7). It specifies protocol enhancements for support of Number Portability (NP) in ISDN/SS7 networks, based on ITU-T Recommendation Q.769.1 (2000) as modified by ETSI.

What does SIST EN 302 097 V1.2.2:2005 specify?

SIST EN 302 097 V1.2.2:2005 specifies protocol enhancements used to support number portability in signalling networks. The scope ties the work to requirements from the Network Aspects (NA) task force on number portability, so the standard is aimed at network-side behaviour rather than end-user services.

The endorsed text is organized around the scope, references, and an annex on Dropback procedures. ETSI’s endorsement notice states that Annex D is not applicable in this version.

What are the key requirements of SIST EN 302 097 V1.2.2:2005?

SIST EN 302 097 V1.2.2:2005 is an ETSI-modified adoption of ITU-T Recommendation Q.769.1 (2000). In practice, that means implementers use the ITU-T base text and apply the ETSI modifications listed in the endorsement notice.

• Clause 1, Scope - the endorsed standard keeps the number-portability focus, but deletes the fourth bullet point linked to Annex D. For readers, this means the Dropback material is not part of the applicable text.
• Clause 2, References - the standard adds ETSI EN 300 356-1 and ETSI EN 300 356-2. These references matter because they provide the related ISUP version 4 material for basic services and supplementary services.
• Annex D - the entire annex on ProcedurestosupportDropback is deleted. In practice, equipment or network procedures should not rely on that annex in this version.
• Q.730 reference context - the deleted Annex D had pointed to procedures for Pivot Routeing or Redirection in ITU-T Recommendation Q.730. The practical effect is that those procedures are not part of the endorsed document here.
• NA task force basis - the scope says the enhancements follow requirements imposed by the NA task force on number portability. This tells engineers the standard is aligned to network-architecture work on NP, not just a generic signalling update.

What terms does SIST EN 302 097 V1.2.2:2005 define?

• Integrated Services Digital Network (ISDN) - the digital network type named in the standard’s title and subject.
• Signalling System No. 7 (SS7) - the signalling system over which the ISUP procedures operate.
• ISDN User Part (ISUP) - the SS7 user part covered by the protocol enhancements.
• Number Portability (NP) - the network capability the standard is intended to support.
• Network Aspects (NA) - the task force named as the source of the number-portability requirements.
• Dropback - the procedure family mentioned in Annex D, which is deleted as not applicable in this version.
• Pivot Routeing - the routing method referenced in the deleted annex through the Q.730 link.
• Redirection - the alternative handling method also referenced in the deleted annex.

Who uses SIST EN 302 097 V1.2.2:2005?

SIST EN 302 097 V1.2.2:2005 is used by telecom network engineers, switch and signalling equipment vendors, and operators working with ISDN/SS7 networks. It is also relevant to standards specialists and procurement or quality teams that need to check whether an implementation supports Number Portability in the way ETSI intended.

In practice, users consult it when planning, implementing, or validating ISUP signalling behaviour for number portability. It helps them align network software and documentation with the ETSI-modified ITU-T base recommendation.

Which standards are used with SIST EN 302 097 V1.2.2:2005?

• ETSI EN 300 356-1 - provides ISUP version 4 for the international interface, Part 1 for basic services.
• ETSI EN 300 356-2 - provides ISUP version 4 for the international interface, Part 2 for ISDN supplementary services.
• ITU-T Recommendation Q.730 - supplies the Pivot Routeing and Redirection procedures cited in the deleted Dropback annex.
• ETSI TR 101 119, TR 101 118, TR 101 122 - background documents on number portability, network architecture, and numbering/addressing.
• ETSI EG 201 367 - supporting material on Intelligent Network support for service provider number portability.

What does the SIST EN 302 097 V1.2.2:2005 document contain?

SIST EN 302 097 V1.2.2:2005 contains the ETSI endorsement notice, copyright and IPR notices, the scope and references modifications, and a note that Annex D is deleted. It also includes bibliographic support items and a short document history showing the publication stages.

The front matter identifies the standard as a Slovenian standard identical to EN 302 097 Version 1.2.2. The history block records the adoption and publication trail, while the bibliography points readers to related ETSI documents on number portability and related network architecture topics.
