SIST EN 301 487-1 V1.1.1:2005 is the Slovenian adoption of ETSI EN 301 487-1, a B-ISDN standard for Digital Subscriber Signalling No. two (DSS2). It specifies the protocol for switched virtual path capability at the TB reference point, so it is mainly relevant to B-ISDN equipment makers, network operators, and test teams working on access and switching functions.

What does SIST EN 301 487-1 V1.1.1:2005 specify?

SIST EN 301 487-1 V1.1.1:2005 specifies the stage three signalling protocol for establishing, maintaining, and clearing switched virtual path capability in the Broadband Integrated Services Digital Network (B-ISDN). It applies to DSS2 operation at the TB reference point, or at coincident SB and TB reference points, and it also covers the protocol requirements when the service is provided to the user via a private B-ISDN.

The document is organized as part 1 of a six-part series:

Part	What it covers
Part 1	Protocol specification
Part 2	Protocol Implementation Conformance Statement (PICS) proformas specification
Part 3	Test Suite Structure and Test Purposes (TSS&TP) specifications for the user
Part 4	Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proformas specification for the user
Part 5	Test Suite Structure and Test Purpose (TSS&TP) specification for the network
Part 6	Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proformas specification for the network

In practice, Part 1 defines the protocol behaviour, while the later parts support conformance testing and implementation declarations.

What are the key requirements of SIST EN 301 487-1 V1.1.1:2005?

SIST EN 301 487-1 V1.1.1:2005 focuses on the signalling procedures and switching functions needed to support a telecommunications service. For implementers, the important point is that this is not just a service description - it ties the service to DSS2 protocol behaviour at the user-network interface.

Protocol scope and service context

The standard applies to equipment that supports connection-oriented basic B-ISDN telecommunication services on either side of a TB reference point, including use at coincident SB and TB reference points as access to the public B-ISDN. It also states that the service requires support for the basic point-to-point call/bearer connections defined in EN 300 443-1 and the Additional Traffic Capabilities defined in the EN 301 068 series.

TB reference point use

The document notes that procedures at the TB reference point support access of a private B-ISDN to the public B-ISDN. It also says that some procedures are applicable only at the TB reference point. In practice, this tells implementers where the signalling rules apply in real network topologies.

Limits of the scope

The standard does not cover specific requirements of individual B-ISDN connection-oriented basic telecommunication services. That matters for buyers and system integrators because they still need service-specific standards or profiles when they are implementing a particular bearer service.

Conformance and testing structure

Part 1 is linked to the later test and conformance parts of the series. This matters because suppliers can use the series together to describe the implementation, build test cases, and document whether a product supports the protocol correctly.

Reference handling inside the endorsed text

The endorsement notice updates cross-references throughout ITU-T Recommendation Q.2934 to ETSI-modified documents such as EN 300 443-1, EN 301 068, EN 301 067-1, EN 301 003-1, EN 301 276-1, ETS 300 661-1 to ETS 300 668-1, EN 301 485-1, and EN 301 486-1. For users, this means the ETSI versions are the ones to follow when applying the protocol text.

What terms does SIST EN 301 487-1 V1.1.1:2005 define?

• B-ISDN - Broadband Integrated Services Digital Network, the broadband ISDN environment for which the protocol is written.
• DSS2 - Digital Subscriber Signalling No. two, the signalling system used for the protocol procedures.
• Switched virtual path capability - the capability to establish, maintain, and clear a virtual path by signalling.
• Stage three - the level of service specification that identifies the protocol procedures and switching functions needed to support the service.
• TB reference point - the reference point at which the signalling rules in this standard are applied.
• PICS - Protocol Implementation Conformance Statement, used to declare what an implementation supports.
• ATS - Abstract Test Suite, used to structure conformance testing.

Who uses SIST EN 301 487-1 V1.1.1:2005?

This standard is used by B-ISDN equipment manufacturers, DSS2 protocol implementers, network operators, and conformance test laboratories. It is also relevant to quality managers and buyers who need to check whether a product supports switched virtual path capability at the B-ISDN user-network interface.

What changed in SIST EN 301 487-1 V1.1.1:2005 from the previous edition?

SIST EN 301 487-1 V1.1.1:2005 is an endorsement of ITU-T Recommendation Q.2934 with ETSI modifications. The endorsement notice replaces clause 1 with an ETSI scope statement, adds a references clause, and updates references throughout the text to ETSI-associated EN and ETS documents. It also states that new or modified text is shown with sidebars, underlining, and strike-out.

Which standards are used with SIST EN 301 487-1 V1.1.1:2005?

The standard relies on several related documents for call control, traffic parameters, and supplementary services:

• EN 300 443-1 - basic call/bearer control at the B-ISDN user-network interface
• EN 301 068 series - connection characteristics, ATM transfer capability, and traffic parameter indication
• EN 301 067-1 - negotiation during call/connection establishment
• EN 301 003-1 - peak cell rate modification by the connection owner
• EN 301 276-1 - sustainable cell rate parameter modifications
• ETS 300 661-1 to ETS 300 668-1 - DSS2 supplementary services such as DDI, MSN, CLIP, CLIR, COLP, COLR, SUB, CUG, and UUS
• EN 301 485-1 - ATM endsystem addressing format by number identification supplementary services
• EN 301 486-1 - ATM traffic descriptor modification with negotiation by the connection owner
• ITU-T I.371, I.356, I.130, I.413 - traffic control, ATM cell transfer performance, service characterization, and the B-ISDN user-network interface

What does the SIST EN 301 487-1 V1.1.1:2005 document contain?

The document contains an ETSI endorsement notice for ITU-T Recommendation Q.2934, including the modified scope text and the updated reference clause. It also includes a reference mapping table that shows how the original ITU-T references are replaced by ETSI-modified references throughout the protocol text.

The foreword identifies the series structure for Parts 1 to 6, which separates protocol specification from conformance and test material. The front matter also includes the publication history, national transposition dates, and the ETSI intellectual property notice.
