Foreword
This European Telecommunication Standard (ETS) has been produced by the Transmission and
Multiplexing (TM) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is one of a family of ETSs covering various aspects of Synchronous Digital Hierarchy (SDH)
equipment standards and has been produced in order to provide the Implementation Conformance
Statement (ICS) proforma to be used in connection with conformance/approval testing of SDH equipment.
The structure of this ETS
The ICS proforma will ultimately consist of 8 sub-parts of ETS 300 417, numbered 1-2 to 8-2, each of
which will correspond to sub-parts 1-1 to 8-1 of ETS 300 417, respectively. The ICS sub-parts are:
Part 1-2: ETS 300 417-1-2: "General information about Implementation Conformance Statement
(ICS) proforma";
Part 2-2: ETS 300 417-2-2: "Physical section layer functions Implementation Conformance Statement
(ICS) proforma";
Part 3-2: ETS 300 417-3-2: "STM-N regenerator and multiplex section layer functions Implementation
Conformance Statement (ICS) proforma";
Part 4-2: ETS 300 417-4-2: "SDH path layer functions Implementation Conformance Statement (ICS)
proforma";
Part 5-2: ETS 300 417-5-2: "PDH path layer functions Implementation Conformance Statement (ICS)
proforma";
Part 6-2: ETS 300 417-6-2: "Synchronization distribution layer functions Implementation Conformance
Statement (ICS) proforma";
Part 7-2: ETS 300 417-7-2: "Auxiliary layer functions Implementation Conformance Statement (ICS)
proforma";
Part 8-2: ETS 300 417-8-2: "Major compound functions, Implementation Conformance Statement
(ICS) proforma".

Date of adoption of this ETS: 4 October 1996
Date of latest announcement of this ETS (doa): 31 January 1997

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 given profile. Such a statement is called an
Implementation Conformance Statement (ICS).
A client of a test laboratory who requests a conformance/approval test should provide the test laboratory
with a completed ICS proforma for each layer to be tested and a detailed system description of the
implementation.

The ICS proforma is not another complete description of the related specification, but rather a compact
form of its static conformance requirements, to be used by the test laboratory to identify which test should
be performed on a given implementation. Not every feature of a profile specification is contained in the
related ICS proforma. For particular cases requiring specific information, the ICS can refer to the
appropriate clause of the related specification by means of references, notes and or comments.
The ICS proforma captures the implementation flexibility allowed by the related specification and details
which options are left to the implementor, and which are conditionally dependent on other options taken by
the implementor.

1 Scope
This European Telecommunication Standard (ETS) provides general information about the
Implementation Conformance Statement (ICS) proforma structure and contents, as well as guidance for
filling-in the document. The ICS proforma for a Synchronous Digital Hierarchy (SDH) Network Element
(NE) are defined in compliance with the relevant requirements, and in accordance with the relevant
guidance, given in ISO/IEC 9646-7 [4], in ETS 300 406 [5] and in ETR 212 (see annex C).
The ICS proforma is a normative part of the reference specification.
The supplier of an implementation which is claimed to conform to ETS 300 417-1-1 [6] is required to
complete a copy of these ICS proforma, namely this ETS, and is further required to provide all information
necessary to identify both the implementation (e.g. specify it by means of a detailed system description)
and the supplier.
The client of the test laboratory might be identified by means of the System Conformance Statement
(SCS) and a client checklist. Those proforma are included in annex B of this ETS. The use of SCS
proforma and client checklist is not mandatory, any suitable means of providing such information is
acceptable.
According to ETS 300 406 [5] the ICS proforma has two main objectives:
- within the context of conformance testing, to be the reference document for the conformance
assessment process related to the Implementation Under Test (IUT);
- outside the context of conformance testing, to provide an overview of the implementation.
Concerning the conformance assessment process, the ICS proforma is used:
- as the description of the IUT for the static conformance review;
- as an element of description of the IUT capabilities for the test case deselection;
- as an element of description of the IUT for the test suite parameterization;
- as a reference document for the analysis of the results;
- for inclusion with the final test report.
Outside the conformance testing context, the ICS proforma is or may be used:
- to provide an overview of the capability supported by the implementation (see note);
- to statically check the interworking capacities of two implementations;
- as a standard checklist of the base specification conformance requirements.
When requesting conformance/approval testing of an SDH layer implementation, the supplier should
always fill all the ICS proforma relevant for that layer. In the case where more than one instance of the
same layer appears in the detailed system description, the client of a test laboratory should clearly identify
any differences existing between these instances (if any).
NOTE: Each capability of the ICS associated implementation is described as a conformance
statement which is the result of the answer, by the supplier, to the dedicated ICS item.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS the following definitions apply:
homogeneous layer instances: (refer also to the definition of a layer instance given below)
Homogeneous layer instances are a set of layer instances supporting the same features; hence, under the
point of view of a conformance verdict they can be considered as one single Implementation Under Test
(IUT).

particular system. It is a statement of the capabilities and options which have been i
