• Abstract:

  Reference document: ITU-T Recommendation I.365.3. The purpose of this standard is to endorse the Reference document as a part of the ETSI production. Development of an EN for the SSCF required on top of the protocol specified in Q.2110 (SSCOP) to provide the layer service specified in X.213 (CONS) on the basis of the corresponding results in ITU-T SG13 Q6.

SIST EN 301 117 V1.1.1:2003 is the Slovenian adoption of ETSI EN 301 117 V1.1.1, which endorses ITU-T Recommendation I.365.3 for the Service Specific Co-ordination Function (SSCF) in Broadband Integrated Services Digital Network (B-ISDN) ATM Adaptation Layer (AAL). It specifies the SSCF used to provide the Connection-Oriented Transport Service (COTS) on top of Q.2110 (SSCOP) and the service defined in X.213 (CONS), so it is mainly relevant to people implementing or assessing B-ISDN and ATM protocol stacks.

What does SIST EN 301 117 V1.1.1:2003 specify?

SIST EN 301 117 V1.1.1:2003 specifies the ETSI endorsement of ITU-T Recommendation I.365.3 (1995) as a European Standard, without modification. In practice, that means the document does not redefine the protocol itself; it makes the ITU-T text part of the ETSI/EN framework for B-ISDN ATM adaptation layer work.

The standard is about the SSCF used to provide COTS. The scope ties that function to the protocol in Q.2110 (SSCOP) and to the layer service in X.213 (CONS), so the standard sits between the lower protocol support and the higher connection-oriented service that applications expect.

The published text is structured as an ETSI European Standard with front matter, a foreword, an endorsement notice, copyright and IPR statements, and document history. That structure matters because users need to know this is an endorsed reference standard and where its legal and administrative context comes from.

What are the key requirements of SIST EN 301 117 V1.1.1:2003?

SIST EN 301 117 V1.1.1:2003 is an endorsement standard, so its key requirement is that the text of ITU-T Recommendation I.365.3 is approved by ETSI as an EN without modification. For implementers, this means the operative technical content is the referenced ITU-T recommendation itself.

• Use SSCF in the B-ISDN AAL. The standard places SSCF inside the ATM Adaptation Layer. This tells system designers where the function belongs in the protocol stack.
• Provide COTS. The purpose of SSCF here is to support the Connection-Oriented Transport Service. In practice, this is the service behavior the upper layer expects to receive.
• Build on SSCOP from Q.2110. The scope states that SSCF is required on top of the protocol specified in Q.2110 (SSCOP). This matters because SSCF is not standalone; it depends on the lower protocol service.
• Align with CONS from X.213. The document links SSCF to the layer service specified in X.213 (CONS). That gives users the service model the function is intended to support.
• Follow the ITU-T reference text. Because ETSI approved the ITU-T recommendation without change, conformance work should be based on the reference document itself. This is important for procurement, implementation, and interoperability checks.
• Use the ETSI-endorsed version. The foreword records the standard as an ETSI national adoption. For users, that means the EN is the recognized European/Slovenian publication of the same technical content.

What terms does SIST EN 301 117 V1.1.1:2003 define?

• Broadband Integrated Services Digital Network (B-ISDN) - the digital network environment the standard addresses.
• ATM Adaptation Layer (AAL) - the layer in which the SSCF sits.
• Service Specific Co-ordination Function (SSCF) - the function covered by the standard.
• Connection-Oriented Transport Service (COTS) - the transport service SSCF is intended to provide.
• European Standard (EN) - the ETSI publication type used for this endorsed text.
• European Telecommunications Standards Institute (ETSI) - the organization that endorsed the ITU-T recommendation as an EN.
• ITU-T Recommendation I.365.3 - the reference document adopted by this standard.
• Q.2110 (SSCOP) and X.213 (CONS) - the related protocol and service references named in the scope.

Who uses SIST EN 301 117 V1.1.1:2003?

SIST EN 301 117 V1.1.1:2003 is used by telecommunications engineers, protocol implementers, and systems architects working on B-ISDN and ATM equipment. It is also relevant to quality teams, conformity assessors, and buyers who need to confirm that a product’s connection-oriented transport behavior follows the ETSI-endorsed ITU-T reference.

Which standards are used with SIST EN 301 117 V1.1.1:2003?

The standard is built around ITU-T Recommendation I.365.3 (1995), which it endorses as an EN. It also points to Q.2110 (SSCOP) for the underlying protocol support and X.213 (CONS) for the service model that SSCF is meant to provide.

What does the SIST EN 301 117 V1.1.1:2003 document contain?

The document contains the endorsement notice, which states that ETSI approved ITU-T Recommendation I.365.3 as an EN without modification. It also includes the foreword with adoption dates, copyright and reproduction notices, an IPR statement, and a short history block. The content is therefore mainly administrative and referential, rather than a full protocol specification written out in ETSI form.
