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.
From Product Idea to Executable Workflow
The design-time chain that produces what Lead-to-Cash executes — portfolio governance, catalog governance, and the implementation function that turns a published catalog into running workflows.
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.
Commercial Configuration Engine
The vendor-neutral engine room of commercial configuration: how a product catalog becomes a priced, approvable, margin-aware, contractable quote — catalog and bundling mechanics, matrix pricing, discounting and multi-currency, margin modeling, and contract lifecycle.
The Order Orchestration Chain
How commercial orders decompose into service orders and resource orders, with orchestration at every layer.
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.
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.
Trouble-to-Resolve — the ITSM & Operations Domain
The post-fulfilment domain. Once a service is activated, ownership moves from L2C to Trouble-to-Resolve (T2R) — the ITSM and operations estate that starts the SLA clock and runs incident, problem, change and asset management. Covers 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.
Monolith vs Microservices vs ODA
Comparing traditional, microservices, and TM Forum ODA approaches to BSS/OSS architecture.
Real-World Implementations
Factual comparison of major BSS/OSS vendors: what they cover, where they excel, and common deployment patterns.
Enterprise BSS Patterns
How enterprise BSS differs from consumer: account hierarchies, contract-first ordering, solution-level CPQ, and contract lifecycle management.
