Course benefits
 SDH is rapidly becoming a core network technology employed by international communications operators and enterprise data network users alike.

This unique course has been designed to meet the needs of network support staff requiring a comprehensive and relevant grounding in SDH networks and technologies.

Who should attend?
All staff responsible for the planning, design, management or support of networks employing SDH technology. Network managers, network engineers and all involved with SDH-based networks will find this course invaluable.

Pre-requisites
A thorough knowledge of networking fundamentals, data transmission principles and the OSI 7-layer model is required prior to attending this course. Course 301: Introduction to Datacommunications and Networking is recommended as a minimum level of experience.
