Master telecom architecture — from catalog design to order orchestration
A vendor-neutral training platform for understanding modern telecom BSS/OSS architecture, catalog-driven design, and TM Forum standards.
Built by Nick Mudie
Start LearningA structured curriculum covering BSS/OSS foundations, catalog modeling, order orchestration, TM Forum standards, and real-world vendor implementations.
BSS/OSS Core Concepts
Understand the fundamental architecture of telecom BSS and OSS systems, catalog-driven design, and the critical distinction between commercial and technical domains.
Product, Service & Resource Catalogs
Master the three-layer catalog model: Product Offerings and Specifications, CFS/RFS decomposition, and how catalogs drive the entire order-to-activate chain.
The Order Orchestration Chain
How commercial orders decompose into service orders and resource orders, with orchestration at every layer.
Service & Resource Inventory
Managing the lifecycle of instantiated services and resources, from activation through modification to termination.
API-First Integration
How TMF Open APIs enable interoperability between BSS/OSS components, with real API mapping per domain.
Lead-to-Cash & Trouble-to-Resolve
End-to-end process walkthroughs mapped to eTOM L2-L4, showing which systems participate at each step.
Real-World Implementations
Factual comparison of major BSS/OSS vendors: what they cover, where they excel, and common deployment patterns.
Monolith vs Microservices vs ODA
Comparing traditional, microservices, and TM Forum ODA approaches to BSS/OSS architecture.
MANO, NSO & Service Orchestration
How SOM integrates with ETSI MANO and Cisco NSO for VNF/CNF lifecycle management and network service orchestration, including Day-0/1/2 responsibilities and RFS-to-engine mapping.
Enterprise, Wholesale & Partner
Enterprise-specific BSS patterns: B2B vs B2C differences, enterprise CPQ, multi-site ordering, SLA-based pricing, partner/wholesale, and enterprise MACD.
