SDH Network Specialist

The SDH Network Specialist online training course provides a comprehensive, practical understanding of Synchronous Digital Hierarchy (SDH) in modern telecommunications. You will learn how SDH is built, how traffic is multiplexed and transported, how protection schemes keep services running during failures, and how to monitor and troubleshoot SDH networks using a structured, evidence-based approach.

The training focuses on real-world SDH scenarios you’ll see in the field, including STM optical links, E1/E3 tributaries, virtual containers and mapping, concatenation, ring and linear protection, timing and synchronisation, network management principles, performance monitoring, and fault localisation. It is designed to help technicians confidently commission, maintain, and diagnose SDH networks in operational environments.

What SDH you will learn

• Understand what SDH is, why it replaced many PDH limitations, and where SDH still fits in modern networks

• Explain SDH fundamentals including frame structure, overhead, pointers, trace identifiers, and common alarms

• Identify SDH network elements and equipment functions including regenerators, ADMs, and cross-connects

• Map services using SDH multiplexing hierarchy: containers, virtual containers (VC), and service routing concepts

• Apply SDH concatenation concepts and understand how higher bandwidth services are carried over SDH

• Understand and apply SDH protection schemes including linear protection (1+1, 1:N, 1:N+1) and ring protection (UPSR, BLSR)

• Use SDH network management concepts for controlled operations: fault, performance, configuration, and inventory management

• Perform performance monitoring and fault localisation using alarms, counters (B2/B3, ES/SES), traces, and layered testing

• Follow practical testing and maintenance procedures including commissioning checks, baselines, protection testing, and structured troubleshooting workflows
