SIST EN 301 276-1 V1.1.3:2005 is the Slovenian adoption of ETSI EN 301 276-1 V1.1.3 for Broadband Integrated Services Digital Network (B-ISDN) signalling. It specifies the Digital Subscriber Signalling System No. 2 (DSS2) protocol for modifying ATM Traffic Descriptor parameters on established connections, including Sustainable Cell Rate (SCR). It is intended for equipment and access arrangements at the TB reference point or the coincident SB and TB reference point.

What does SIST EN 301 276-1 V1.1.3:2005 specify?

SIST EN 301 276-1 V1.1.3:2005 specifies the signalling protocol for ATM Traffic Descriptor modification in B-ISDN access. It covers the protocol details for changing connection characteristics after a call or connection has already been set up.

The document is organized as a protocol specification with clause 1 on scope, clause 2 on references, and an informative Appendix I. The foreword also identifies the wider six-part series, where this part is the protocol specification and the other parts cover conformance and test specifications.

This standard applies to public B-ISDN access and also to private B-ISDN when the service is provided to the user at the TB reference point. It does not cover emulated N-ISDN services, and point-to-multipoint peak cell rate modification is outside its scope.

What are the key requirements of SIST EN 301 276-1 V1.1.3:2005?

SIST EN 301 276-1 V1.1.3:2005 sets the signalling rules for modifying the ATM Traffic Descriptor by DSS2. In practice, this is the control procedure that lets the connection owner change traffic parameters on an active connection.

• Clause 1 extends the Peak Cell Rate (PCR) modification capability from EN 301 003-1 to include Sustainable Cell Rate (SCR) and Maximum Burst Size (MBS). This matters because implementations must handle more than one traffic parameter when a service changes.
• Clause 1 limits the service to connection-oriented telecommunications based on single point-to-point calls or connections. That means equipment for multipoint calling does not use this protocol for PCR modification.
• Clause 1 applies the protocol at the TB reference point or the coincident SB and TB reference point. In practice, vendors need to design interface behaviour for those access positions.
• Clause 1 says the capability is for call or connection sets that are already established. This is the live-connection update case, not initial call setup.
• Clause 1 also states that the service needs the protocol for basic point-to-point call or bearer connections from EN 300 443-1. So implementers must support the underlying basic B-ISDN call control as well.
• Clause 2 and the endorsement notice update the references used in the text to ETSI-modified versions of related ITU-T recommendations. This keeps the protocol aligned with the companion signalling specifications.
• Appendix I has informative status. Readers can use it for background or guidance, but not as the core protocol requirement text.

What terms does SIST EN 301 276-1 V1.1.3:2005 define?

• Broadband Integrated Services Digital Network (B-ISDN) - the broadband network environment for which this signalling protocol is written.
• Digital Subscriber Signalling System No. 2 (DSS2) - the signalling system used to carry the protocol messages for B-ISDN user-network control.
• ATM Traffic Descriptor - the set of traffic parameters that describes how a connection uses the network.
• Peak Cell Rate (PCR) - the traffic rate parameter whose modification capability is extended by this standard.
• Sustainable Cell Rate (SCR) - the sustained traffic rate parameter that this standard adds to the modification procedure.
• Maximum Burst Size (MBS) - the burst parameter that can be modified together with the other traffic descriptor values.

Who uses SIST EN 301 276-1 V1.1.3:2005?

SIST EN 301 276-1 V1.1.3:2005 is used by telecommunications equipment manufacturers, network operators, and test laboratories working with B-ISDN and ATM signalling. It is also relevant to engineers who design or integrate access equipment at the TB reference point, and to quality or conformance teams checking that a product follows the DSS2 protocol.

Buyers and specification writers can use it to confirm whether a device supports ATM Traffic Descriptor modification on established point-to-point connections. Test and certification teams use the linked conformance and test parts to prepare PICS, TSS&TP, ATS, and PIXIT material.

What changed in SIST EN 301 276-1 V1.1.3:2005 from the base ITU-T recommendation?

SIST EN 301 276-1 V1.1.3:2005 applies ITU-T Recommendation Q.2963.2 (1997) with ETSI modifications. The endorsement notice replaces clause 1 with the ETSI scope for ATM Traffic Descriptor modification, adds clause 2 references to EN 300 443-1 and EN 301 068-1, updates in-text references to use the ETSI-modified versions of related recommendations, and gives Appendix I informative status.

What does the SIST EN 301 276-1 V1.1.3:2005 document contain?

The document contains the protocol specification for ATM Traffic Descriptor modification over DSS2 in B-ISDN. It includes the scope text, the reference list, and the ETSI endorsement changes that replace clause 1 and update clause 2.

It also shows how the standard fits into the six-part EN 301 276 series. Appendix I is present as an informative annex, and the document records the national adoption and publication history.
