SIST EN 301 141-2 V1.2.2:2005 is the Slovenian standard for the Protocol Implementation Conformance Statement (PICS) proforma of Integrated Services Digital Network (ISDN) Narrowband Multi-service Delivery System (NMDS). It specifies the questionnaire and completion rules used to record which NMDS capabilities an implementation supports, so suppliers, network operators, and conformance testers can compare a product or system against EN 301 141-1.
What does SIST EN 301 141-2 V1.2.2:2005 specify?
SIST EN 301 141-2 V1.2.2:2005 provides the PICS proforma for NMDS defined in EN 301 141-1. It is used to state implementation options in a standardized way, so a network operator can set requirements for an Access Network (AN) or Service Node (SN), or check whether an implementation meets them.
The document is organized into clauses 1 to 4 and one normative annex.
| Annex | What it covers |
|---|---|
| Annex A | Protocol ICS proforma for EN 301 141-1, including guidance, identification fields, conformance statement, Local Exchange, Network terminating node, and powering under failure conditions |
What are the key requirements of SIST EN 301 141-2 V1.2.2:2005?
Clause 4 requires a conforming PICS to be technically equivalent to the proforma in Annex A, with the same numbering, naming, and ordering of items. In practice, a supplier cannot rearrange the form or rename items if it wants the completed PICS to remain conforming.
Annex A.1 sets the completion rules. The tables use status markings such as mandatory, optional, not applicable, prohibited, qualified optional, and conditional, and the supplier must answer the support and values fields using the given notation. This matters because the form is not free text - it is a structured declaration of what the implementation really supports.
Annex A.1.2 also defines how to record multiple-profile support and conditional answers. A support cell can point to a conditional expression, and the note on received PDUs says that supporting a PDU means being able to parse all valid parameters of that PDU. In practice, partial parsing of a claimed PDU support is treated as non-conformant.
Annex A.1.3 limits who completes which parts of the form. Tables in the AN role are for user implementations, and tables in the SN role are for network implementations. That keeps one PICS from mixing irrelevant answers for different deployment roles.
Annex A.2 asks for identification data: the date of the statement, Implementation Under Test (IUT), System Under Test (SUT), supplier, client if different, and a contact person. This ties the conformance statement to a specific product, configuration, and responsible contact.
Annex A.4 contains the global conformance question. All mandatory capabilities must be marked as implemented, and a negative answer means the implementation is not conformant to the protocol specification. For buyers and labs, this is the first quick check before deeper review.
Annexes A.5, A.6, and A.8 cover the actual capability areas to declare:
- Local Exchange or Network terminating node main features, including ISDN-BA and PSTN support
- PSTN port combinations supported
- Protocol conformance for the NMDS-specific PSTN and ISDN-BA message sets
- Physical layer options, including the NMDS physical layer and the ETS 300 012-1 option
- Powering user ports under local power failure conditions
What terms does SIST EN 301 141-2 V1.2.2:2005 define?
- PICS - Protocol Implementation Conformance Statement, a statement from a supplier that says which capabilities an implementation has implemented.
- ICS proforma - A questionnaire form that becomes an Implementation Conformance Statement when it is completed.
- Protocol ICS (PICS) - An ICS for an implementation or system that claims conformance to a protocol specification.
- IUT - Implementation Under Test, the specific implementation being assessed.
- SUT - System Under Test, the system that contains the IUT.
- AN - Access Network, one of the intended deployment roles for NMDS.
- SN - Service Node, the other intended deployment role for NMDS.
- ISDN-BA - Integrated Services Digital Network - Basic Access, used as a named capability in the proforma.
Who uses SIST EN 301 141-2 V1.2.2:2005?
NMDS equipment suppliers use this standard to prepare a formal PICS for a product or system. Network operators use it to state what capabilities they require from an AN or SN implementation and to compare candidate solutions consistently.
Conformance test laboratories and reviewers use it for static conformance review, where the completed PICS is compared with the requirements in EN 301 141-1. Quality managers and procurement teams use it to document supported options, port configurations, message sets, and failure-powering behaviour before acceptance or rollout.
Which standards are used with SIST EN 301 141-2 V1.2.2:2005?
- EN 301 141-1 - Defines the NMDS interface specification that the PICS proforma refers to throughout Annex A.
- ETS 300 406 - Gives the standard methodology for protocol and profile conformance testing.
- ISO/IEC 9646-1 - Provides the general concepts and framework for conformance testing.
- ISO/IEC 9646-7 - Provides the rules for Implementation Conformance Statements and the tabular PICS notation.
- ETS 300 012-1 - Supplies the ISDN basic user network interface layer 1 specification referenced in the physical layer options.
- ETR 080 - Listed in the bibliography as related background on ISDN basic rate access and digital transmission on metallic local lines.
What does the SIST EN 301 141-2 V1.2.2:2005 document contain?
The document contains the PICS completion guidance, identification fields for the implementation and system, and a global conformance question. It then provides tables for Local Exchange and Network terminating node capability declarations, including PSTN and ISDN-BA options, PSTN port selections, message-set support, physical layer options, and powering of user ports during local power failure.
Annex A is the practical heart of the document because it is the form that gets completed and, if needed, published as the implementation’s conformance statement. The tables and notes are designed for design reviews, acceptance testing, and conformance documentation rather than for describing the protocol itself.

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).

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.
