SIST EN 301 815-1 V1.1.1:2005 is the Slovenian adoption of ETSI EN 301 815-1 V1.1.1 for Broadband Integrated Services Digital Network (B-ISDN) signalling. It specifies the Digital Subscriber Signalling System No. two (DSS2) protocol for indicating Quality of Service (QoS) class and QoS parameters during call/connection establishment. The document is aimed at equipment and service implementations at the TB reference point, and at coincident SB and TB reference points when used for access to the public B-ISDN.

What does SIST EN 301 815-1 V1.1.1:2005 specify?

SIST EN 301 815-1 V1.1.1:2005 is a Part 1 protocol specification that endorses ITU-T Recommendations Q.2965.1 and Q.2965.2 with ETSI modifications. The scope is the stage three signalling for QoS class indication and QoS parameter indication in B-ISDN call/connection establishment.

In practice, the standard is about the messages and procedures needed to carry QoS information in DSS2 signalling. It applies to the call/connection establishment phase only, so implementers use it when designing or checking signalling before a connection is set up, not for later operation of the connection.

The document is organized around:

• the foreword and endorsement notice
• modifications to ITU-T Recommendation Q.2965.1
• modifications to ITU-T Recommendation Q.2965.2
• history

What are the key requirements of SIST EN 301 815-1 V1.1.1:2005?

Service scope

SIST EN 301 815-1 V1.1.1:2005 specifies stage three of the QoS class indication service and the QoS parameters indication service for the pan-European B-ISDN. Stage three is the level that identifies the protocol, procedures and switching functions needed to support the service.

For users, this means the document focuses on signalling behavior rather than service marketing or network planning. An implementer needs to make the DSS2 exchange carry the relevant QoS information correctly during setup.

Applicability of the signalling

SIST EN 301 815-1 V1.1.1:2005 applies at the TB reference point and at coincident SB and TB reference points when used to access the public B-ISDN. It also covers the case where the service is provided to the user via a private B-ISDN.

This matters because the implementation target is tied to the network interface. Vendors and operators need to verify that the equipment sits at the right reference point and supports the required DSS2 behavior there.

What QoS information is covered

SIST EN 301 815-1 V1.1.1:2005 covers both QoS classes and individual QoS parameters. The modifications say the signalling supports QoS classes beyond those already covered in basic call/connection control, and for point-to-multipoint calls it also applies to the first party.

That means the document is relevant when the connection setup must carry either a class-based QoS choice or more detailed QoS parameter information. Implementers should check which of the two their equipment advertises and handles.

Related protocol dependencies

SIST EN 301 815-1 V1.1.1:2005 depends on the basic point-to-point call/bearer connection control specified in EN 300 443-1. For the point-to-multipoint case, it refers to EN 300 771-1.

In practice, this means the QoS indication capability is not standalone. A system that does not already support the base DSS2 call/bearer control procedures cannot use this part on its own.

What terms does SIST EN 301 815-1 V1.1.1:2005 define?

• Broadband Integrated Services Digital Network (B-ISDN) - the broadband network context in which the DSS2 signalling is used.
• Digital Subscriber Signalling System No. two (DSS2) - the layer 3 signalling system used for the user-network interface.
• Quality of Service (QoS) - the service quality information that the signalling carries as a class or as individual parameters.
• Stage three - the specification level that covers protocol, procedures and switching functions.
• TB reference point - the reference point where the signalling applies at the user-network interface.
• SB reference point - another reference point mentioned for coincident SB and TB access to public B-ISDN.
• Protocol Implementation Conformance Statement (PICS) - the type of conformance proforma named in Part 2 of the multi-part standard.

Who uses SIST EN 301 815-1 V1.1.1:2005?

SIST EN 301 815-1 V1.1.1:2005 is used by equipment designers, network engineers, and telecommunications operators working with B-ISDN access signalling. It is relevant where a system must indicate QoS class or QoS parameters during connection setup over DSS2.

Quality managers and test teams use it to check that the implementation follows the specified signalling behavior at the TB reference point. It is also useful for buyers comparing equipment that claims support for B-ISDN DSS2 QoS indication.

What does the SIST EN 301 815-1 V1.1.1:2005 document contain?

The document contains the ETSI endorsement notice for the two ITU-T recommendations and the detailed modifications that adapt them for European B-ISDN use. It includes replaced scope text, updated normative references, and reference-substitution tables for both Q.2965.1 and Q.2965.2.

It also records the document history and publication information. For readers implementing or testing equipment, the useful content is the modified protocol description and the list of dependent standards that the signalling assumes.
