SDH principles

What you will learn:

This online course provides a thorough introduction to SDH concepts - frame structure, virtual containers, overhead bytes, and the multiplexing hierarchy - giving engineers the foundation they need to work confidently on SDH equipment and networks.

 

By the end of this course you will be able to:

• describe the advantages of the SDH.    
• describe the capabilites 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. 

 

Course prerequisites:

An understanding of the basic principles of time division multiplexing and synchronous transmission. It is recommended that the PTT e-learning course "Synchronous transmission fundamentals" is studied before attempting this "SDH principles" course.

 

Approximate study time: 7 hours 

 

Delivery platform requirements:
