Master telecom architecture — from catalog design to order orchestration
A vendor-neutral educational 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.
Physical & Logical Resource Inventory
Managing physical and logical network resources — devices, ports, VLANs, IP addresses, and topology. How Resource Inventory feeds activation, capacity planning, and service assurance.
From Usage to Cash
Rating, charging, mediation, subscription billing, interconnect & roaming, convergent billing, revenue assurance, and dunning — how telcos turn service usage into revenue.
Bridging Fulfilment and Assurance
How Lead-to-Cash fulfilment connects to Service Assurance and Trouble-to-Resolve — the handoff via SLM, service and resource data, CMDB integration, feedback loops, and what breaks when the bridge is missing.
API-First Integration
How TMF Open APIs enable interoperability between BSS/OSS components, with real API mapping per domain.
ODA, eTOM, SID, TAM & Process Flows
The core TM Forum frameworks — Open Digital Architecture (ODA), Business Process Framework (eTOM), Information Framework (SID), and Functional Framework (TAM) — with end-to-end process walkthroughs.
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.
Network Integration & Service Orchestration
How OSS orchestrates fulfilment across IP/MPLS, mobile core, transport, and access domains. Establishes the strict layering between COM/SOM, cross-domain orchestration, and ROM/domain controllers, and works through the integration patterns, protocols, and worked examples that turn an RFS into configured network state.
Enterprise BSS Patterns
How enterprise BSS differs from consumer: account hierarchies, contract-first ordering, and solution-level CPQ.
