Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is part 2 of a multi-part standard covering the V5.1 interface specification as described below:
Part 1: V5.1 interface specification;
Part 2: Protocol Implementation Conformance Statement (PICS) proforma;
Part 3: Test Suite Structure and Test Purposes (TSS&TP).
NOTE 1: At the time of publication of this ETS, the final structure of further part(s) and/or
separate ETS(s) containing the test specifications was still under study.
To evaluate conformance of a particular implementation, it is necessary to have a statement of which
capabilities and options have been implemented for a given Open Systems Interconnection (OSI)
protocol. Such a statement is called a Protocol Implementation Conformance Statement (PICS).
NOTE 2: It is however possible to use this ETS to indicate the basic requirements for an Access
Network (AN) or a Local Exchange (LE) required by a network operator. Specific
requirements need to be added, e.g. the Public Switched Telephone Network (PSTN)
port characteristics and conditions.

1 Scope
This second part of ETS 300 324 defines the Protocol Implementation Conformance Statement (PICS)
proforma for the implementation flexibility allowed for a V5.1 interface defined in ETS 300 324-1 [1]. It
allows either the Network Operator to formulate the requirements for V5.1 interface implemented in an
Access Network (AN) or Local Exchange (LE), 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.
This ETS is in compliance with the relevant requirements and in accordance with the relevant guidance
given in ISO/IEC 9646-7 [3].
2 Normative references
This ETS incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest
edition of the publication referred to applies.
[1] ETS 300 324-1 (1993): "Signalling Protocols and Switching (SPS);
V interfaces at the digital Local Exchange (LE); V5.1 interface for the
support of Access Network (AN); Part 1: V5.1 interface specification".
[2] ISO/IEC 9646-1: "Information technology - Open systems interconnection -

concepts".

Conformance Statements".
3 Definitions
For the purposes of this ETS, the following definitions apply:
Protocol Implementation Conformance Statement (PICS): a statement made by the supplier of an
Open System Interconnection (OSI) implementation or system, stating which capabilities have been
implemented for a given OSI protocol (see ISO/IEC 9646-1 [2]).
PICS proforma: a document, in the form of a questionnaire, designed by the protocol specifier or
conformance test suite specifier, which when completed for an OSI implementation or system becomes
the PICS (see ISO/IEC 9646-1 [2]).
Static conformance review: a review of the extent to which the static conformance requirements are met
by the Implementation Under Test (IUT), accomplished by comparing the PICS with the static
conformance requirements expressed in the relevant standard(s) (see ISO/IEC 9646-1 [2]).

N/A Not supported, not applicable or the conditions for status are not met
No not supported
NOT Boolean "not"
NT1 Network Termination 1
O Option (may be selected to suit the implementation, provided that any
requirements applicable to the option are observed)
O.n Options, but support required for either at least one or only one of the options in
the group labelled with the same numeral "n"
OR Boolean "or"
OSI Open Systems Interconnection
PICS Protocol Implementation Conformance Statement
PSTN Public Switched Telephone Network
SCS System Conformance Statement
SUT System Under Test
TS Time Slot
Yes Supported
5 Conformance
The supplier of a protocol implementation which is claimed to conform to ETS 300 324-1 [1] is required to
complete a copy of the PICS proforma provided in this ETS and is required to provide the information
necessary to identify both the supplier and the implementation.

6.3 Identification of the protocol
This PICS proforma applies to the following standard:
ETS 300 324-1 (1994): "Signalling Protocols and Switching (SPS); V interfaces at the digital Local
Exchange (LE); V5.1 interface for the support of Access Network (AN); Part 1: V5.1 interface
specification".
6.4 Global statement of conformance
The implementation described in this PICS meets all the mandatory requirements of the referenced
standard.
[ ] Yes
[ ] No
NOTE: Answering "No" to this question indicates non-conformance to the protocol specification.
Non-supported mandatory capabilities are to be identified in the PICS, with an
explanation of why the implementation is non-conforming.
