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 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

Posted on Nana Appiah25 February 2025 I was enrolled on the complimentary LTE Fundamentals Training Course, good course completed the LTE Fundamtals test passed. The information on LTE was clear ans very layout.Posted on Stanley Lim6 February 2025 The contents of courses are comprehensive and detailed, equipping individuals with the skills necessary for their profession.Posted on Kirk Brotherton1 February 2025 I’ve found SATOMS very easy to use thus far - having a flexible timeframe for completion has allowed me to work on my VSAT Course when time permits, which works great for me as I work 9 to 5. Looking forward to completing my course and becoming qualified in my chosen field(s). Thanks SATOMS!Posted on Wee Seng Wilson Ng (Wil)1 February 2025 Enrolled in VSAT Installer course previously and went through everything at my own pace. The good: 1. Online based using browser, thus no need for top of the line computers, even your browser on smartphone works. The bad: 1. The interface will be stuck, and I can't proceed to next module until emailing support, no idea why this happens but it just does to me. Hope the issue is solved, or do not happen frequently.Posted on Augustin Bernard16 January 2025 Personal Experience: As someone who has completed the Fundamentals of LTE Technology training, I found the course to be incredibly informative and engaging. The content was straightforward and easy to understand, making it accessible for beginners while still providing valuable insights for more experienced learners. Overall, the training provided a comprehensive overview of LTE's purpose, historical context, and its pivotal role in modern telecommunications. It equipped me with the knowledge and skills needed to appreciate the significance of LTE and its impact on the industry.

The knowledge gained has given me valuable experience. The courses are easy instructor lead with clear content. i have also forwarded and recommended colleagues to do so at the same note.Posted on Anthony Baker28 October 2024 Great Course, full of valuable informationPosted on Andre Nzolameso17 July 2024 I have done VSAT training in good condition and I am satisfied with manything learn in this course and hope I will be able to enroll to another.Posted on Raj Ramlagan1 December 2023 Satoms is very helpful to understanding fundamentals of satellite communications including ground station design, forward and return links and their associated modulation/demodulation and coding methods. Highly recommend their training modules.
