Discover the Principles and Potential of SDH Networks.

DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c43368) has announced the addition of E-Learning Course: SDH Payloads to their offering.

"SDH Payloads" describes the payload capabilities of SDH links and the methods of carrying different types of payload over an SDH network. This course covers such topics as virtual containers and the transport of ATM, IP and Ethernet traffic over an SDH network.

Course aim: After completing this course a trainee will be able to describe how different types of traffic are transported over an SDH network. The role and significance of Tributary Units is discussed and the methods of carrying plesiochronous, synchronous and asynchronous traffic described. The role of the different types of SDH overhead is also explained.

Pre-requisites: Understanding of the principles of the SDH and an understanding of the principles of packet switching including ATM and the Internet Protocol (IP); knowledge of the principles and components of an Ethernet LAN would also be advantageous. It is recommended that SyncNet course B: "Principles of SDH", TransNet course D "ATM principles", and the Ethernet courses A and B ("Ethernet fundamentals" and "Ethernet networks") are studied before attempting this course

.

A Transmission principles

B SDH principles

C Optical line systems inc WDM

D SDH payloads

E SDH networks

F SDH network management and maintenance

Target audience:

- Those studying for a career in telecommunications and who require a detailed knowledge of modern optical broadband transmission networks.

- Technical staff involved in the operation, installation or maintenance of SDH-based broadband networks.
