SIST EN 301 815-2 V1.1.1:2005 is the Slovenian adoption of ETSI EN 301 815-2 for Broadband Integrated Services Digital Network (B-ISDN) Digital Subscriber Signalling System No. two (DSS2). It specifies a Protocol Implementation Conformance Statement (PICS) proforma for quality of service class and parameter indication at call/connection establishment, so suppliers can declare exactly which protocol capabilities an implementation supports.

What does SIST EN 301 815-2 V1.1.1:2005 specify?

SIST EN 301 815-2 V1.1.1:2005 specifies the PICS proforma for the protocol defined in EN 301 815-1. It is a conformance-statement document, not the protocol specification itself and not a test suite.

The standard sits in a multi-part series for the DSS2 protocol support of QoS class and parameters indication at call/connection establishment. The foreword identifies parts 1 to 6, with this part covering the PICS proforma and other parts covering protocol specification, test suite structure and test purposes, and abstract test suite material.

Annex	What it covers
Annex A	The PICS tables to be completed by the supplier, including major and subsidiary capabilities for user and network roles

The document says the supplier of a claimed conformant implementation shall complete the annex A PICS form and identify the supplier and the implementation. It also ties conformance to support for either basic point-to-point call/bearer connections or point-to-multipoint call/bearer connections.

What are the key requirements of SIST EN 301 815-2 V1.1.1:2005?

SIST EN 301 815-2 V1.1.1:2005 is mainly a checklist for declaring support, so the key requirement is to state capabilities clearly and consistently. The annex A tables show what must be marked for user and network roles, and several items depend on whether specific options are supported.

PICS completion and conformance declaration

The supplier completes the PICS proforma in annex A and provides information that identifies the supplier and the implementation. In practice, this is the document a reviewer uses to see what the product claims before any deeper testing starts.

User-role capabilities

For the user role, the proforma checks whether an implementation can send or analyse QoS-related information in SETUP messages. For Q.2965.1B, the user role covers outgoing calls with a QoS parameter information element and incoming calls that analyse that element; at least one of those options is mandatory.

For Q.2965.2B, the user role extends this to End-to-end transit delay and Extended QoS parameter handling. The form asks whether the implementation can include, analyse, or receive these information elements in SETUP and CONNECT messages, so the implementer must show how call setup behaves at both ends.

Network-role capabilities

The network role mirrors the same signaling functions from the network side. The tables ask whether the implementation can analyse or include QoS parameter, End-to-end transit delay, and Extended QoS parameter information elements in SETUP and CONNECT messages.

This matters because conformance depends on the behavior of both sides of call establishment, not just one endpoint. A product team should use these questions to map signaling behavior to actual support in the stack.

Valid combinations and subsidiary capabilities

Several items require the information element to appear in a valid combination with bearer class, broadband transfer capability, ATM traffic descriptor, and QoS parameters or QoS class. In practice, this means the implementation must handle the field combinations correctly, not only recognize individual fields.

The subsidiary-capability tables cover maximum end-to-end transit delay, updating cumulative delay values, rejecting a call when the delay limit is exceeded, and automatically generating delay or Extended QoS parameters information elements when needed. These are the detailed behaviors that matter when the implementation derives, forwards, or enforces delay values during call setup.

What terms does SIST EN 301 815-2 V1.1.1:2005 define?

• Protocol Implementation Conformance Statement (PICS) - a statement of which capabilities and options an implementation supports.
• B-ISDN - the broadband integrated services digital network addressed by the document.
• DSS2 - the Digital Subscriber Signalling System No. two protocol used for the signaling defined here.
• QoS - quality of service, meaning the class and parameters signaled at call/connection establishment.
• SETUP - the message used in the tables for carrying or analysing the QoS and delay information elements.
• CONNECT - the message used for some of the included or analysed information-element cases.
• ATM traffic descriptor - one of the parameters used in the valid-combination checks in the tables.

Who uses SIST EN 301 815-2 V1.1.1:2005?

Suppliers of B-ISDN DSS2 implementations use SIST EN 301 815-2 V1.1.1:2005 when preparing a conformance statement for EN 301 815-1. Test laboratories, protocol engineers, and compliance teams use it to check which call-establishment behaviors are supported in user and network roles.

It is also useful to quality managers and buyers who need to review a supplier declaration and understand whether the implementation supports basic point-to-point or point-to-multipoint call/bearer connections with the required QoS signaling.

What does the SIST EN 301 815-2 V1.1.1:2005 document contain?

The document contains endorsement notes that adapt the ITU-T recommendations for ETSI use, plus annex A with the completion tables. Those tables use yes/no/N/A style answers and comments fields to record support for major and subsidiary capabilities.

It also includes the clause references that link each capability to the relevant parts of the protocol specification. That makes it usable as a practical declaration form for implementation review, conformance assessment, and related testing work.

Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Services and Protocols for Advanced Networks (SPAN). The present document is part 2 of a multi-part deliverable covering the Digital Subscriber Signalling System No. two (DSS2) protocol specification for the Broadband Integrated Services Digital Network (B-ISDN) to support Quality of Service class and parameters indication at call/connection establishment, as identified below: Part 1: "Protocol specification [ITU-T Recommendations Q.2965.1 (1999) and Q.2965.2 (1999), modified]"; Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification
