Study Notes

OSS/BSS in Telecom

OSS (Operational Support Systems) and BSS (Business Support Systems) are essential for managing telecom networks and services.
TMN (Telecommunication Management Network) and TMF (TeleManagement Forum) TOM (Telecommunication Operations Model) are frameworks that guide telecom operations.

TMN Model vs TMF (TOM) Model

The TMN model focuses on the management layer of telecom systems.
The TMF TOM model provides a standardized approach for capturing telecom business processes and services.

eTOM Concepts & Principles

Domain: A classification area that groups objects sharing common architectural characteristics.
Vertical Context: Represents stages in the lifecycle of an enterprise, illustrating process lineage.
Process Decomposition: Breaks down processes hierarchically, revealing finer details at each decomposition level.

eTOM Level 3 View

Provides a detailed framework for telecom operations, showcasing interrelations between various business processes and functionalities.

SID - Shared Information and Data

Domain: Similar to eTOM, it encompasses objects with specific architectural characteristics.
ABE (Aggregate Business Entities): Defined sets of data and operations representing cohesive, loosely coupled business entities.
Business Entity: Understandable concepts from a business perspective, characterized by attributes and relationships.

Definitions in SID

Domain: Groups objects based on shared architectural traits.
ABE: A cohesive collection that characterizes sets of related business operations.
Business Entity (BE): Concepts with attributes and relationships defined easily from a business perspective.
Attribute: A fact that describes a business entity, providing essential information about its properties.
Relationship: An association of interest involving two business entities or a business entity with itself, highlighting their interconnections.
