DURATION: 1 Day

Course Overview:

Synchronous Digital Hierarchy, SDH, standardized the way information is multiplexed and transmitted over fiber-based Optical Transport Networks. This seminar provides the fundamental basics of PDH and SDH transport networks and protocols. This seminar also provides the background needed to understand more advanced transport topics, such as, how packet data can be carried efficiently over SDH.

Course Outline:

1. General Introduction:

The Development of the Communications Network (from fires on mountaintops to Pulse Code Modulation)

2. Introduction to PDH:

Time Division Multiplexing – TDM
Space and Time Division Switching
PDH Protocols: T1 – USA; E1 – Euro/Global
- Framing
- Error Detection and Reporting
- Network Management
- Multiplex Levels
- Synchronization

3. Introduction to SDH

Optical Ingredients
Synchronization and Timing
Optical Protocol Framing: STS-1 Frame; STM- Frame

4. Multiplexing:

High-Order (HO) Multiplexing
Low-Order (LO) Multiplexing
