Overview

SIST EN 301 141-2 V1.2.2:2005 is a Slovenian standard identical to EN 301 141-2, developed under the European Telecommunications Standards Institute (ETSI). The standard specifies the Protocol Implementation Conformance Statement (PICS) proforma for the Narrowband Multi-service Delivery System (NMDS) as defined in EN 301 141-1. The PICS proforma serves as a standardized template, allowing suppliers of Integrated Services Digital Network (ISDN) NMDS implementations to state their protocol conformance precisely and transparently.

The standard plays a vital role for network operators, service providers, and equipment manufacturers in the telecommunications sector. It facilitates clear communication of conformance to required and optional functionalities, supporting both procurement and regulatory compliance activities.

Key Topics

• Protocol Implementation Conformance Statement (PICS):
  A structured and standardized way for suppliers to declare which capabilities and functional options are implemented in their ISDN NMDS solution.

• Conformance Evaluation:
  Enables a static review of the extent to which an implementation meets the requirements specified in EN 301 141-1, using clear tables and references.

• Options and Mandatory Capabilities:
  Differentiates between mandatory protocol features and optional functionalities, including various PSTN port support combinations and message set implementations.

• System Roles:
  The proforma covers both Access Network (AN) and Service Node (SN) roles, ensuring comprehensive applicability.

• Guidance for Use:
  Includes instructions for completing the proforma, ensuring consistency and enabling valid comparisons between different products or profiles.

• Standardized Terminology and Notation:
  Adopts conventions from ISO/IEC 9646-7, including standard statuses such as mandatory, optional, and conditional options, for clarity and interoperability.

Applications

The PICS proforma in SIST EN 301 141-2 V1.2.2:2005 offers practical value in several scenarios:

• Procurement and Tendering:
  Network operators can request or verify PICS statements from vendors to ensure equipment meets their technical requirements for ISDN NMDS functionality.

• Product Development:
  Manufacturers utilize the template to guide development and document conformance, streamlining certification and market entry.

• Regulatory and Market Access:
  The proforma structure supports compliance checks with national or international interoperability requirements in the ISDN context.

• Quality Assurance and Auditing:
  Enables systematic conformance assessment, supporting internal quality control as well as formal audits.

• Technical Communication:
  Provides a common language for protocol features, enabling suppliers and buyers to communicate capabilities robustly and efficiently.

• Profile-specific Implementations:
  Supports declaration of conformance for systems that offer multiple service profiles, enhancing flexibility and market competitiveness.

Related Standards

SIST EN 301 141-2 V1.2.2:2005 references and complements several key standards in ISDN and protocol conformance evaluation:

• EN 301 141-1:
  Narrowband Multi-service Delivery System (NMDS) - Part 1: Interface specification

• ETS 300 012-1:
  ISDN Basic User Network Interface (UNI) - Layer 1 specification

• ETS 300 406:
  Methods for Testing and Specification (MTS); Protocol and profile conformance testing specifications

• ISO/IEC 9646-1 and ISO/IEC 9646-7:
  Open Systems Interconnection (OSI) - Conformance testing methodology and framework, and Implementation Conformance Statements

• ETR 080:
  Transmission and Multiplexing related to ISDN basic rate access

Adopting SIST EN 301 141-2 helps ensure ISDN NMDS devices and networks are robust, interoperable, and market-ready, streamlining certification processes across Europe and supporting digital network standardization.

Introduction
To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and
options have been implemented for a telecommunication specification. Such a statement is called a Protocol
Implementation Conformance Statement (PICS).
ETSI

1 Scope
The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for the
"Narrowband Multi-service Delivery System (NMDS)" defined in EN 301 141-1 [3] in compliance with the relevant
requirements, and in accordance with the relevant guidance given in ISO/IEC 9646-7 [5] and ETS 300 406 [2].
It allows either the network operator to formulate the requirements for an NMDS implemented in an Access Network
(AN) or a Service Node (SN), or to decide whether an implementation meets these requirements. It details in tabular
form the implementation options, i.e. the optional functions additional to those which are mandatory to implement.

A.1 Guidance for completing the PICS proforma
A.1.1 Purposes and structure
The purpose of this PICS proforma is to provide a mechanism whereby a supplier of an implementation of the
requirements defined in EN 301 141-1 [3] may provide information about the implementation in a standardized manner.
The PICS proforma is subdivided into subclauses for the following categories of information:
- guidance for completing the PICS proforma;
- identification of the implementation;
- identification of the protocol;
- global statement of conformance;
- .
A.1.2 Abbreviations and conventions
The PICS proforma contained in this annex is comprised of information in tabular form in accordance with the
guidelines presented in ISO/IEC 9646-7 [5].
Item column
The item column contains a number which identifies the item in the table.
Item description column
The item description column describes in free text each respective item (e.g. parameters, timers, etc.). It implicitly
means "is supported by the implementation?".
Status column
The following notations, defined in ISO/IEC 9646-7 [5], are used for the status column:
m mandatory - the capability is required to be supported.
o optional - the capability may be supported or not.
n/a not applicable - in the given context, it is impossible to use the capability.
x prohibited (excluded) - there is a requirement not to use this capability in the given context.
o.i qualified optional - for mutually exclusive or selectable options from a set. "i" is an integer which
identifies an unique group of related optional items and the logic of their selection which is defined
immediately following the table.
ci conditional - the requirement on the capability ("m", "o", "x" or "n/a") depends on the support of
other optional or conditional items. "i" is an integer identifying an unique conditional status
expression which is defined immediately following the table.
