SIST EN 300 417-2-2 V1.1.4:2003 is the Slovenian standard identical to EN 300 417-2-2 Version 1.1.4. It gives the Implementation Conformance Statement (ICS) proforma for the SDH and PDH physical section layer functions defined in EN 300 417-2-1, so a supplier can state which capabilities an implementation supports in a standard format. It is aimed at equipment suppliers, test laboratories and buyers or operators who need a layer-by-layer conformance statement for transmission equipment.

What does SIST EN 300 417-2-2 V1.1.4:2003 specify?

SIST EN 300 417-2-2 V1.1.4:2003 specifies the ICS proforma used to describe conformance to the SDH and PDH physical section layer functions of EN 300 417-2-1. In practice, it tells the supplier what to record, how to mark each item as mandatory, optional or conditional, and how to present the answer so it can be used in conformance testing.

The document is organized as a short main text plus normative annexes. Clause 4 states how a completed ICS must match the proforma structure and ordering. Annex A explains how to complete the forms, and Annexes B-L provide layer-specific proformas.

What are the key requirements of SIST EN 300 417-2-2 V1.1.4:2003?

How the ICS must be completed

Clause 4 requires a conforming ICS to be technically equivalent to the annex proforma and to preserve the numbering, naming and order of the items. It also says a separate ICS proforma is needed for each layer instance. That matters because conformance is checked per implemented layer, not just for the whole product.

Annex A gives the completion rules. The status column uses the standard ICS meanings - mandatory, optional, not applicable, prohibited, qualified optional and conditional - and the support column is filled by the supplier with yes/no-style answers. For multiple-profile systems, the supplier can use conditional expressions linked to the System Conformance Statement (SCS), so one form can still show which options are supported in each profile.

What the layer annexes ask you to declare

Annexes B-D cover the optical section layers OS1, OS4 and OS16. Each annex asks for identification of the implementation, a global statement of conformance, a layer description, transmission tables, and defect, fault and performance monitoring tables. The layer description requires at least one trail termination function, with adaptation functions linked to the chosen source or sink side.

Each optical annex also classifies the interface by application and source type. The proforma distinguishes intra-office, short-haul and long-haul use cases, then ties them to source wavelength range, spectral width, launched power, extinction ratio, receiver sensitivity, overload and reflectance. In practice, the supplier must declare the exact optical class and interface characteristics, not just say that the port is “optical”.

What the monitoring and fault items cover

The optical annexes include defect handling for Loss Of Signal (dLOS), Loss Of Frame (dLOF), Trail Signal Fail (aTSF), Server Signal Fail (aSSF), Alarm Indication Signal (aAIS), defect correlation and performance monitoring. They also cover port status modes such as NMON, MON and AUTO, plus the reporting of Out Of Frame Second (pOFS) to the Equipment Management Function (EMF). That tells a tester or buyer what alarms and status behaviour the implementation must expose.

The electrical annexes follow the same pattern for ES1, E4, E31, E22, E12, T12 and E0, but their tables focus on data stream, connection function, trail termination and adaptation functions, followed by defect and performance monitoring.

What terms does SIST EN 300 417-2-2 V1.1.4:2003 define?

• Implementation Conformance Statement (ICS) - a statement from the supplier saying which capabilities an implementation supports for a given specification.
• ICS proforma - the questionnaire form that is completed to become an ICS.
• Implementation Under Test (IUT) - the specific implementation instance being assessed.
• System Under Test (SUT) - the system that contains the IUT.
• Equipment Management Function (EMF) - the management function that receives reported fault causes and performance information.
• Alarm Indication Signal (AIS) - a signal inserted when a higher-layer failure needs to be indicated downstream.
• Loss Of Signal (dLOS) - the defect declared when the received optical signal falls below the operational level and frame alignment would be interrupted.

Who uses SIST EN 300 417-2-2 V1.1.4:2003?

Suppliers of SDH and PDH transport equipment use this standard to complete conformance declarations for optical and electrical section layers. Test laboratories use it to decide which conformance tests apply to a given implementation. Buyers, operators and quality teams use it to compare vendor declarations in a consistent way and to check that the declared layer functions, monitoring behaviour and interface class are the ones they need.

What changed in SIST EN 300 417-2-2 V1.1.4:2003 from the previous edition?

ETSI states that this version was published because the previous two versions had incorrect dates in the transposition table. The foreword also says the EN family was converted from ETS 300 417 without technical changes, while some editorial corrections were made, including fixes in parts 2-1, 2-2 and 3-2.

Which standards are used with SIST EN 300 417-2-2 V1.1.4:2003?

• EN 300 417-2-1 - supplies the physical section layer functions that this ICS proforma profiles.
• EN 300 417-1-1 - supplies the generic processes and performance terms used for defect, fault and monitoring behaviour.
• EN 300 417-6-1 - is part of the same transport-functionality family and is listed as a companion part.
• ETS 300 406 and ISO/IEC 9646-7 - provide the conformance testing and ICS methodology used to structure the proforma.
• ISO/IEC 9646-1 - gives the general conformance testing concepts used in the definitions.
• ETS 300 232 and ITU-T G.957 - provide the optical interface characteristics used in the optical annexes.
• ITU-T G.652, G.653 and G.654 - define the fibre types referenced by the long-haul optical options.
• ETS 300 166, ETS 300 167, ETS 300 337, CCITT G.703, G.704, G.706, G.742, G.751, ITU-T G.823, G.825 and G.958 - support the electrical-interface, framing, jitter and transmission behaviour referenced in the proforma.

What does the SIST EN 300 417-2-2 V1.1.4:2003 document contain?

The document contains standardized questionnaire forms for layer conformance, with identification fields for the IUT, SUT, supplier, client and contact person. It also contains tables for optical and electrical layer functions, including source and sink functions, adaptation functions, wavelength and power characteristics, receiver limits, jitter, framing and monitoring behaviour.

Annex A gives the rules for interpreting the item, status and support columns and for using conditional expressions. The annex tables include the kinds of values and test-related declarations that a laboratory needs to select the right checks, but the standard overview does not reproduce the table values, masks or formulas.

Such a statement is called an ImplementationConformance Statement (ICS).A client of a test laboratory who requests a conformance / approval test shall provide to the test laboratory a completedICS 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 staticconformance requirements, to be used by the test laboratory to identify which test shall be performed on a givenimplementation. Not every feature of a profile specification is contained in the related ICS proforma. For particularcases requiring specific information the ICS can refer to the appropriate clause of the related specification by means ofreferences, notes and or comments.The ICS proforma captures the implementation flexibility allowed by the related specification and details which optionare left to the implementor, which are conditionally dependent on other option taken by the implementor.SIST EN 300 417-2-2 V1.1.4:2003
