Study Notes

OSS/BSS in Telecom

OSS (Operations Support Systems) and BSS (Business Support Systems) are critical components in telecommunications for managing network operations and business processes.

TMN and TMF TOM Model

TMN (Telecommunications Management Network) and TMF (TeleManagement Forum) TOM (Framework) models define structures for telecom management.

FAB Components

FAB (Framework for Application-Based) components relate to the integration of systems in a telecom environment for better operational efficiency.

eTOM - Concepts & Principles

eTOM (enhanced Telecom Operations Map) provides a framework for classifying telecom processes, focusing on common architectural characteristics.

Domain Classification

Domain signifies a categorized area containing objects sharing specific architectural features vital for effective telecom management.

Vertical Context

Represents stages or partitions in the lifecycle of the enterprise, crucial for understanding operational processes.

Process Decomposition

Involves hierarchical breakdown of processes, revealing finer details and enhancing clarity at each level of the structure.

eTOM – Level 3 View

A detailed representation of telecom processes organized to facilitate analysis, management, and operational efficiency.

SID - Shared Information and Data

SID (Shared Information/Data) framework emphasizes consistent data management across telecom systems.

Domains and Level 1 ABEs

Domains in SID classify collections of objects, while Level 1 ABEs (Aggregate Business Entities) define cohesive sets of information and operations linked to business processes.

ABE - Aggregate

An ABE is a well-defined set that encapsulates information and operations, ensuring loose coupling for enhanced modularity.

Business Entity

Business Entities (BEs) are fundamental concepts defined from a business perspective, with identifiable attributes and relationships.

Attribute

An attribute conveys characteristics that describe various aspects of a business entity, contributing to clearer data representation.

Relationship

A relationship defines the associations of interest between business entities or within the same entity, crucial for understanding data interconnections.
