Overview

SIST EN 300 292 V1.2.1:2003 defines a functional specification for managing call routeing information within the Telecommunications Management Network (TMN), focusing specifically on the exchange aspects of circuit-switched networks. The standard outlines a management information model for the routeing and digit analysis function at the Operations System/Network Element (OS/NE) interface, also known as the Q3 interface. Developed by SIST in alignment with ETSI guidelines, this standard addresses the need for effective management and control of routeing data, ensuring interoperability and enhanced efficiency in modern telecommunication systems.

Key Topics

• Routeing and Digit Analysis Management: The standard introduces a structured approach to the management of routeing information, covering digit rebuilding, digit analysis, outgoing digit preparation, and circuit end point selection within exchanges.
• Circuit-Switched Networks: The scope is limited to the NE aspects of circuit-switched networks, focusing on exchanges using standardized signalling systems such as DSS1, CCITT No.5 (C5), SS No.7 (ISUP only), and R2 regional signalling.
• Object-Oriented Information Model: The document provides a detailed model based on specific object classes (OCs) required for efficient routeing information management. These OCs facilitate entry and exit points for customer administration, subscriber-controlled input, intelligent network functionality, and specific treatments.
• OS/NE (Q3) Interface: Emphasizes the element management layer perspective, restricted to what a network switch directly manages, rather than the entire network scope.

Exclusions: The standard does not address management of directory number (DN) portability, cordless terminal mobility, dynamic routeing, traffic management, or comprehensive call-control functions.

Applications

SIST EN 300 292 V1.2.1:2003 offers practical value to telecommunications operators and equipment vendors by enabling:

• Centralized Routeing Data Management: Efficient administration of routeing information across multiple exchanges, leading to reduced operational complexity and improved network reliability.
• Network Element Interoperability: Ensures that Operations Systems can communicate effectively with network elements, leveraging standardized interfaces and information models for routeing and digit analysis functions.
• Enhanced Network Visualization: Supports the management and monitoring of locally originating, terminating, and transit calls at the element level within telecom exchanges.
• Support for Various Signalling Systems: The model accommodates different signalling protocols, making it adaptable to a wide range of existing telephone networks.

Through standardized management, network performance can be optimized, and configuration changes can be more easily coordinated, improving overall service quality and enabling future network expansions.

Related Standards

• ITU-T Recommendation M.3010: Defines the general principles of TMN and its architecture, providing foundational context for the OS/NE interface.
• ETS 300 291: Relates to customer administration aspects in network management.
• ITU-T Q.824.x Series: Addresses additional customer administration features.
• ETS 300 637, ITU-T Q.823: Cover aspects of traffic management that are complementary but outside the scope of SIST EN 300 292 V1.2.1:2003.
• EN 300 292: The European adoption of this specification, aligning with international telecommunication management practices.

By adhering to SIST EN 300 292 V1.2.1:2003, network stakeholders can ensure consistent, secure, and robust management of call routeing information, supporting operational excellence in today's dynamic telecommunications landscape.

ETSIEN 300 292 V1.2.1 (1998-08)81ScopeThe present document provides a management information model [12] which covers the management aspects of the"routing and digit analysis" function in an exchange. The scope is further limited to the exchange aspects of circuitswitched networks. This model is restricted to the Operations Systems (OSs) to Network Element (Q3) interface(see ITU-T Recommendation M.3010 [7]).The information to be managed is limited to the signalling systems Digital Subscriber Signalling System No. 1 (DSS1) ,Signalling System CCITT No.5 (C5), Signalling System Number 7 (SS No.7) - ISDN User Part (ISUP) only) andRegional Signalling 2 (R2). (SS No.7 with Telephone User Part (TUP) level 4 is not considered.) The information forrouting purpose, which needs to be maintained by the manager, depends on the signalling systems used by the exchange.This information model can be applied for exchanges with the known standardized signalling systems DSS 1, SS No. 7,R2, C5. Because of the existence of different signalling systems, not all attributes and objects will be applicable for allexchanges. Information about applicability can be found in the object classes behaviour.As this model only offers an element management layer view (ie: limited to a switch) of the routing information, andonly shows the partial view a switch has of its network environment, and does not show the whole network picture, itdoes not provide all the information needed for network-wide management application.The information model covers the management of following aspects:-incoming digit rebuilding;-locally originating, locally terminating (up to recognizing that the Directory Number (DN) belongs to theexchange), and transit calls;-digit analysis;-circuit end point selection;-outgoing digit preparation;as far as they are relevant for routing. It does not cover management of:-DN portability;-Cordless Terminal Mobility (CTM);-Dynamic Routing;due to lack of stable requirements at the time of writing the present document.The information model includes entry/exit points (via instances of specific Object Class (OC)) for:-customer administration (see ITU-T Recommendation Q.824.x [15] or ETS 300 291 [1]);-Subscriber Controlled Input (SCI) (no standard exists yet);-Intelligent Network (IN) (no standard exists yet);-specific treatments as e.g. announcements.The information model does not cover routing or digit analysis aspects of following topics:-traffic management (see ITU-T Recommendation Q.823 [14] or I-ETS 300 637 [2]);-call-control;-broadband;-supplementary services;-IN (Intelligent Network);-customer administration;SIST EN 300 292 V1.2.1:2003

ETSIEN 300 292 V1.2.1 (1998-08)9-other services of which the definition is still under study (e.g. tariff management);-Private Automatic Branch Exchange (PABX) as exchanges or as termination points of subscriber lines (becausethis is covered by customer administration);-centrex implementations;-mobility issues like cellular and personnel mobility;neither following specific points:-characterization of non-blockable digits (e.g. emergency numbers);-characterization of destinations for which carrier dialling is not allowed or ignored e.g. service numbers,emergency calls, specific local calls;-numbering plans for virtual private networks;-blocking of national and/or international traffic due to subscriber permission;-echo suppressor handling depending on selected routing possibility;-use of propagation delay counter;-permanent connections.Because the borders between call processing, digit analysis, routing and traffic management are not always clear, thefollowing rules have been used to differentiate between call processing, digit analysis and routing, and trafficmanagement:-digit analysis and routing processes are related to the end point selection. If a managed item has no relation withthe choice of the end point selection, then this managed item is not included in this model;-call control processes are related to whether or when a call is required to be routed. These processes do notinfluence the end point selection;-the border between traffic management and routing is determined by following conditions:-routing management deals with individual calls under normal conditions;-traffic management optimizes overall traffic flow in case of overload or network failure.Modelling described here does not imply any sequencing of call processing activities.SIST EN 300 292 V1.2.1:2003
