SIST ETS 300 842 E1:2003

• Abstract:

  Development of an ETS for the SSCF required on top of the protocol specified in Q.2110 (SSCOP) tp provide the layer service specified in X.213 (CONS) on the basis of the corresponding results in ITU-T, SG 13, Q 6. In fact this ETS is an endorsement of the ITU-T I.365.3 (1995).

SIST ETS 300 842 E1:2003 is the Slovenian standard published by SIST and identical to ETS 300 842 Edition 1. It covers the Broadband Integrated Services Digital Network (B-ISDN), the ATM Adaptation Layer (AAL), and the Service Specific Co-ordination Function (SSCF) used to provide the Connection-Oriented Network Service (CONS). Engineers working on B-ISDN and ATM-based connection-oriented services use it as the ETSI-endorsed reference for that SSCF function.

What does SIST ETS 300 842 E1:2003 specify?

SIST ETS 300 842 E1:2003 specifies the SSCF needed on top of the protocol in Q.2110 (SSCOP) to provide the layer service defined in X.213 as CONS. In practical terms, it tells implementers where this function sits in the B-ISDN/ATM stack and what service goal it supports.

The standard is an endorsement of the ITU-T recommendation text and is presented without modification. That matters because users should treat the endorsed ITU-T wording as the technical reference rather than expecting ETSI-specific changes.

The document is organized as an ETSI standard with foreword material, transposition dates, an endorsement notice, and document history. The title page also identifies the subject area through the key words AAL, ATM, and B-ISDN.

What are the key requirements of SIST ETS 300 842 E1:2003?

SIST ETS 300 842 E1:2003 requires the SSCF to be used with Q.2110 (SSCOP) to provide CONS. That means the SSCF is not a standalone service - it is the coordination function that supports the connection-oriented service above the SSCOP layer.

The standard is an endorsement of ITU-T Recommendation I.365.2 (1995) without modification. In practice, that means implementers and testers should align their work to the endorsed ITU-T text and not look for an altered ETSI technical profile.

The scope places the standard in the B-ISDN AAL context. For readers, that means the standard is relevant where ATM-based broadband networks need a defined connection-oriented service interface.

The foreword gives the adoption and publication timeline for the ETS. That is useful for procurement, compliance records, and release tracking because it tells users which ETS edition is being referenced in contracts or implementation documents.

The document history identifies this as the first edition. For a team managing product documentation, that helps confirm they are working from the original published ETS text.

What terms does SIST ETS 300 842 E1:2003 define?

• B-ISDN - Broadband Integrated Services Digital Network, the network environment named in the title.
• AAL - ATM Adaptation Layer, the layer where the SSCF sits.
• SSCF - Service Specific Co-ordination Function, the function specified to support CONS.
• SSCOP - The protocol in Q.2110 that the SSCF operates on top of.
• CONS - Connection-Oriented Network Service, the layer service the SSCF helps provide.
• ITU-T Recommendation I.365.2 - The ITU-T text endorsed by ETSI without modification.
• ETS - European Telecommunication Standard, the type of document identified on the cover.

Who uses SIST ETS 300 842 E1:2003?

SIST ETS 300 842 E1:2003 is used by telecom equipment designers, protocol implementers, and test engineers working on B-ISDN and ATM systems. It is also useful for quality managers and buyers who need to check that a product or interface is aligned with the endorsed service model for CONS.

Network architects use it when defining how an SSCF should fit above SSCOP. Conformance and interoperability teams use it when checking that a product follows the referenced ITU-T/ETSI arrangement for connection-oriented service support.

What changed in SIST ETS 300 842 E1:2003 from the previous edition?

SIST ETS 300 842 E1:2003 is identified as the first edition and as the Slovenian standard identical to ETS 300 842 Edition 1. The endorsement notice states that the ITU-T text was approved by ETSI without modification.

Which standards are used with SIST ETS 300 842 E1:2003?

SIST ETS 300 842 E1:2003 is used with Q.2110 (SSCOP), which provides the protocol below the SSCF. It is also used with X.213, which defines the layer service named CONS.

The endorsed technical basis is ITU-T Recommendation I.365.2 (1995). That is the main companion reference for anyone implementing, reviewing, or testing the SSCF defined by this standard.

What does the SIST ETS 300 842 E1:2003 document contain?

SIST ETS 300 842 E1:2003 contains the title page, source and classification information, copyright notice, foreword, transposition dates, endorsement notice, and document history. The foreword records the ETSI adoption and publication timetable, which is useful for administrative tracking and national standardization records.

The endorsement notice states that the ITU-T text was approved without modification. For users, that means the document functions as an endorsed reference to the ITU-T material rather than a heavily edited national specification.
