SDH (Synchronous Digital Hierarchy) is an international standard for synchronous data transmission on optical media. This course provides details of SDH technology, its network elements, framing, overheads, mapping of PDH on to SDH as well as multiplexing to achieve higher order SDH speeds.
- Master the functions of the basic logic functional blocks and topologies supported by SDH
- Understand SDH framing, mapping and multiplexing
- Interpret SDH alarms to locate faults
- Examine the pros and cons of the different protection mechanisms used in SDH
- Describe how the timing signals of the ADM system are distributed and how the NE gets synchronized
On completing this course, participants will be equipped with the technical understanding of SDH networks.
Technical personnel responsible for the planning, design, management or support of optical networks.
