Course description
This course introduces the fundamental principles of the Synchronous Digital Hierarchy (SDH) as employed in modern broadband networks and describes the capabilities and features of SDH networks.
This course is designed for technicians and engineers involved in the design, commissioning and maintenance of synchronous transmission networks.
By the end of this course you will be able to:
- Describe the advantages of the SDH.
- Describe the capabilities of SDH networks, their aggregate bit rates and payload capacities.
- Describe the management facilities of an SDH network and the roles of the elements of a telecoms management network (TMN).
- Describe the basic structure of an STM-1 frame.
- Explain the concepts of pointers, containers, virtual containers and tributary units.
- Describe the purpose, and details, of the multiplex section and regeneration section overheads.
- Describe the purpose, and details, of path overheads.
- Describe the structure of STM-n frames (n=4 to 64) and the purpose of their overheads.
- Describe the role, applications and principles of explicit and virtual concatenation.
