SIST ETS 300 411 E1:2003 is a SIST-adopted European Telecommunications Standard from ETSI for performance monitoring in Synchronous Digital Hierarchy (SDH) networks. It specifies an object-oriented information model for the Network Element (NE) view, so SDH management systems can represent performance-monitoring objects, packages, attributes, and name bindings at the element-management boundary.

What does SIST ETS 300 411 E1:2003 specify?

SIST ETS 300 411 E1:2003 specifies an information model for SDH performance monitoring. It focuses on the NE view and on the managed object classes and properties used to exchange performance data and quality of service alarms with a managing system.

The standard is organized into clauses for scope, normative references, abbreviations, the performance monitoring management model, managed object class definitions, packages, attributes, actions, notifications, parameters, and name bindings. Annex A provides a bibliography.

The scope also makes clear what the document does not cover: protocol stack, network-level management processes, application contexts, conformance requirements, or information models for other systems or equipment. In practice, this means the standard is about the data model, not about how messages are transported or how compliance is tested.

What are the key requirements of SIST ETS 300 411 E1:2003?

The main requirement is to use this ETS as an object-oriented information model for SDH performance monitoring in the NE domain. Clause 1 ties the model to SDH managed objects and to information exchanged over TMN interfaces, so implementers can map performance data into a common management structure.

How the model is framed

Clause 1 says the model covers performance events on specified termination point managed objects and the reporting of performance data and quality of service alarms on a schedule. That matters because the model is not just a list of counters - it is meant to support recurring monitoring and reporting.

Clause 4 states that the SDH performance monitoring requirements are described in G.774.1. Clause 5 then uses IMPORTS to identify the object classes that can be instantiated within the scope of this ETS, and it excludes uninstantiated superclasses. In practice, implementers work only with the defined classes, not with abstract parent classes.

What is defined for implementation

Clause 6 makes the cSESCurrentDataPackage mandatory. This tells an implementer that current consecutive severely errored seconds data is a required part of the package set.

Clauses 5, 6, 7 and 11 define the model structure through imported managed object classes, packages, attributes, and name bindings. The imported names cover current and history data, protection data, adaptation data, SPI data, path termination data, and related bindings to sinks and sources. For a network manager, this is the practical map for where performance data lives and how objects are attached in the NE.

What the model does not include

Clauses 8, 9 and 10 state: no actions, no notifications, and no parameters. That means the standard defines the information model itself, but not command procedures, event notifications, or separate parameter definitions.

What terms does SIST ETS 300 411 E1:2003 define?

• SDH (Synchronous Digital Hierarchy) - The transport hierarchy whose network performance is being modeled.
• NE (Network Element) - The managed equipment domain visible at the element manager to element interface.
• TMN (Telecommunication Management Network) - The management architecture used for exchanging the information described by the model.
• CTP (Connection Termination Point) - A managed termination point used in the model’s object and name-binding structure.
• TTP (Trail Termination Point) - A trail termination point used for associating monitored SDH paths and sections.
• SES (Severely Errored Second) - A performance term used in the monitoring attributes and packages.
• UAS (Unavailable Seconds) - A performance term used for availability-related monitoring data.
• PJC (Pointer Justification Count) - A performance counter included among the modeled attributes.

Who uses SIST ETS 300 411 E1:2003?

SIST ETS 300 411 E1:2003 is used by SDH equipment vendors, TMN implementers, and network management engineers who need a common NE view of performance monitoring data. It is also relevant to operations and maintenance teams that configure, collect, and interpret SDH performance measurements. Quality and integration teams use it to align management objects, packages, and name bindings across SDH network elements.

What changed in SIST ETS 300 411 E1:2003 from the previous edition?

SIST ETS 300 411 E1:2003 is identified as ETS 300 411 Edition 1. The document history records it as the first edition.

Which standards are used with SIST ETS 300 411 E1:2003?

• ITU-T G.709 - Provides the synchronous multiplexing structure referenced by the model.
• ITU-T G.774.1 - Provides the SDH performance monitoring requirements for the NE view.
• CCITT G.784 - Provides SDH management requirements used as the basis for the object model.
• CCITT M.2120 - Provides maintenance and fault-localization context for transport networks.
• CCITT M.3010 - Provides the TMN architecture and interface context.
• ITU-T Q.822 - Provides the generic performance management mechanism used for the object model.

What does the SIST ETS 300 411 E1:2003 document contain?

The body of the document is mainly an ASN.1-style management model. Clauses 5 to 7 list imported managed object classes, packages, and attributes, while clause 11 lists name bindings that connect the objects to SDH termination points and sources. Clauses 8 to 10 state that there are no actions, notifications, or parameters.

Annex A is a bibliography with related ETS, CCITT, and ITU-T references. The document therefore serves as a model definition for design and implementation work, not as a procedure manual or test specification.

1 Scope
This European Telecommunication Standard (ETS) provides an information model for the performance
monitoring of Synchronous Digital Hierarchy (SDH) network. This model describes the managed object
classes and their properties for the performance monitoring function, as defined in CCITT
Recommendation G.784 [3] and as related to SDH Network Elements (NEs). These objects are useful to
describe information exchanged across interfaces defined in CCITT Recommendation M.3010 [5]
Telecommunications Management Network (TMN) architecture for the management of the performance
monitoring function.
SDH performance monitoring functions are used to monitor specified performance events of specified
termination points managed objects and to report these performance data, as well as quality of service
alarms to its managing system according to a given schedule.
CCITT Recommendation M.2120 [4] defines maintenance of transport network, CCITT Recommendation
G.784 [3] defines the management of SDH based NE. This ETS defines the object model based on ITU-T
Recommendation Q.822 [6] according to the requirements described in CCITT Recommendation
G.784 [3] and CCITT Recommendation M.2120 [4]. This model uses generic mechanism defined in ITU-T
Recommendation Q.822 [6].
This ETS defines:
- an information model, as related to the performance monitoring function for the Synchronous Digital
Hierarchy (SDH).
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 here (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.
