SIST ETS 300 371 E2:2005 is the Slovenian adoption of ETS 300 371 Edition 2 from ETSI. It specifies an information model for managing Plesiochronous Digital Hierarchy (PDH) equipment at the Network Element (NE) view, so management systems can represent PDH interfaces in a consistent way.

What does SIST ETS 300 371 E2:2005 specify?

SIST ETS 300 371 E2:2005 defines the information model used at the interface between Network Elements (NEs) and management systems for PDH equipment. It also covers PDH interfaces inside Synchronous Digital Hierarchy (SDH) network elements, where PDH needs to be represented for management purposes.

The scope is limited to the equipment domain visible at the element manager to element interface. The document does not define the protocol stack for communication, network-level management processes, application contexts, conformance requirements, or information models for other systems or equipment.

The document is organized into:

• Clause 1 - Scope
• Clause 2 - Normative references
• Clause 3 - Abbreviations
• Clause 4 - Registration supporting Abstract Syntax Notation No. 1 (ASN.1)
• Clause 5 - PDH fragment, with object classes, attributes, name bindings, and ASN.1 definitions

What are the key requirements of SIST ETS 300 371 E2:2005?

SIST ETS 300 371 E2:2005 is mainly a management information model, so its most important content is the set of managed object classes, attributes, and naming rules that represent PDH interfaces. In practice, this is what an element manager or network management system uses to identify PDH parts, raise alarms, and follow connectivity.

The model is limited to the NE-management domain

Clause 1 states that SIST ETS 300 371 E2:2005 is for management of equipment using PDH at the NE-management interface. It applies only to information available within the element manager domain, not to network-level management information. For implementers, that means the model is about how the managed element presents itself, not about how the wider network is controlled.

The standard registers the ASN.1 object model

Clause 4 defines the registration supporting ASN.1 for ETS 300 371 and assigns object identifiers for managed object classes, packages, name bindings, attributes, actions, and notifications. This matters because management systems need stable identifiers to decode and exchange management information consistently.

It defines PDH physical, connection, and trail objects

Clause 5.1 defines managed objects for the PDH fragment. These include physical interface objects, Connection Termination Point (CTP) objects, Trail Termination Point (TTP) objects, and bidirectional, sink, and source variants. In practice, equipment vendors use these classes to model where signals enter, leave, or terminate inside the managed element.

It gives alarm behavior for common PDH conditions

Several object classes define alarm behavior directly in their behavior text. Loss of Signal (LOS) on the physical sink, Alarm Indication Signal (AIS) on PDH termination objects, Loss Of Frame (LOF) on trail termination objects, and Remote Alarm Indication (RAI) on the bidirectional trail class all trigger communicationsAlarm notifications with the indicated probableCause. This is important because management systems must know which fault condition to report and what operational state change to expect.

It distinguishes the PDH hierarchy levels

The generic PDH classes are labeled by the European PDH hierarchy, with x values corresponding to 64 kbit/s, 2 Mbit/s, 8 Mbit/s, 34 Mbit/s, and 140 Mbit/s. This lets the same management structure be applied across several PDH rates instead of defining a separate model for each one.

It includes interworking with SDH and ATM cells

Clause 5.1.5 defines PDH trail termination point classes for transport of SDH virtual containers and ATM cells. These classes use trail trace attributes such as trTrailTraceExpected, trTrailTraceReceived, and trTrailTraceSend, and they report a trail trace mismatch when the received trace does not match the expected one. In practice, this is the part of the model used when PDH is carrying SDH or ATM traffic.

It provides name bindings for managed object placement

Clause 5.3 defines name bindings that place the PDH objects under managedElement and relate PDH objects to each other through the hierarchy. The bindings also support automatic instance naming and deletion of contained objects where specified. For implementers, this is what makes managed objects appear in the right part of the management tree.

It includes special cases for 64 kbit/s and 2 Mbit/s

The 64 kbit/s and 2 Mbit/s object classes are treated separately in Clause 5.1.9 and Clause 5.1.10. The 64 kbit/s sink class notes that extra features can be added by subclassing, and the 2 Mbit/s sink class notes that alarm handling is tied to byte synchronous mapping. This helps vendors model lower-rate PDH equipment accurately instead of forcing it into a higher-rate pattern.

What terms does SIST ETS 300 371 E2:2005 define?

• Network Element (NE) - The managed equipment domain that the model represents at the element manager interface.
• Plesiochronous Digital Hierarchy (PDH) - The multiplexing structure used by the equipment and interfaces modeled in the standard.
• Connection Termination Point (CTP) - A managed object class for the termination of a PDH connection.
• Trail Termination Point (TTP) - A managed object class for the termination of a PDH trail.
• Alarm Indication Signal (AIS) - A fault condition that the model maps to a communicationsAlarm notification.
• Loss Of Frame (LOF) - A framing fault used by the trail and 2 Mbit/s termination objects to trigger alarm reporting.
• Remote Alarm Indication (RAI) - A condition reported by the bidirectional trail object, with no operational state change.
• Abstract Syntax Notation No. 1 (ASN.1) - The notation used to register the information model and define the data types.

Who uses SIST ETS 300 371 E2:2005?

SIST ETS 300 371 E2:2005 is used by telecommunications equipment vendors, network management system developers, and operators who manage PDH-based equipment. It is also relevant to engineers defining managed objects, alarm behavior, and object naming for PDH interfaces in element management systems.

In practice, users apply it when they need to:

• model PDH physical interfaces, CTPs, and TTPs
• define managed object identifiers and name bindings
• report faults such as LOS, AIS, LOF, and RAI
• manage PDH transport that carries SDH VC's or ATM cells
• keep PDH object naming consistent across rates and equipment types

What changed in SIST ETS 300 371 E2:2005 from the previous edition?

SIST ETS 300 371 E2:2005 is ETS 300 371 Edition 2. The history section shows a first edition in November 1994 and a second edition in October 1996, and the Slovenian standard is stated to be identical to ETS 300 371 Edition 2.

What does the SIST ETS 300 371 E2:2005 document contain?

The document contains the ASN.1 registration module, the PDH object class definitions, attribute definitions, and name binding definitions. It also includes ASN.1 type definitions and figures that show PDH transport object inheritance, naming relationships, connectivity pointer relationships, and examples of how PDH objects relate to transmission functions.

Clause 5 is the core of the document. It covers electrical PDH physical interfaces, PDH AIS termination points, PDH connection termination points, PDH trail termination points, interworking with SDH VC's and ATM cells, and rate-specific object classes for 140 Mbit/s, 34 Mbit/s, 8 Mbit/s, 2 Mbit/s, and 64 kbit/s.

The figures help the reader understand how the object classes fit together. They show inheritance, where objects are instantiated in the managed element tree, and how the model relates to PDH and SDH transmission functions in practice.

1 Scope
This European Telecommunication Standard (ETS) defines the information model to be used at the
interface between Network Elements (NEs) and management systems, for the management of equipment
which use the Plesiochronous Digital Hierarchy (PDH).
This ETS defines:
- the information model for network elements using PDH multiplexing, including PDH interfaces of
Synchronous Digital Hierarchy (SDH) network elements.
This ETS does not define:
- the protocol stack to be used for message communication;
- the network level management processes;
- the application contexts;
- the conformance requirements to be met by an implementation of this information model;
- information models for other systems or equipment.
The information model defined in this ETS (and the corresponding message set) is concerned with the
management of NEs, the equipment by which they are implemented and the functions contained within
them. More precisely, it applies to an equipment domain visible at the element manager to element
interface and is only concerned with information available within that domain. Information proper to the
domain of a network level management process is not included within this model.

5.1.2 European PDH Alarm Indication Signal (AIS) trail termination point
This generic object class represents a particular case of termination point used in a managed element
where no connectivity at respective level is provided. Instances of this object class are used when, in one
layer, no flexibility is provided, but a direct adaptation to client is present.
The sink object class includes the AIS monitoring function of a respective Connection Termination Point
(CTP) which is not instantiated where no connectivity on the respective level is provided. A
communicationsAlarm notification shall be issued if an AIS is detected. The probableCause parameter of
the notification shall indicate AIS.
Object classes inherited from this class are labelled according to the European PDH hierarchy (exTP,
where x = 0 stands for 64 kbit/s, x = 1 for 2 Mbit/s, x = 2 for 8 Mbit/s, x = 3 for 34 Mbit/s and x = 4 for
140 Mbit/s.)
NOTE: The possibility of adding conditional packages (present if the equipment supports the
features) in order to model the capability to reveal Far End Receive Failure (FERF)
