ENG-301E

PDH & SDH DIGITAL TRANSMISSION

Description

A 5-day Training Program to provide participants with an understanding of the Plesiochronous Digital Hierarchy (PDH) transmission and its limitations with respect to the Synchronous Digital Hierarchy (SDH) transmission. A brief description of SONET (Synchronous Optical NETwork) is included, as well as differences between SDH and SONET.

Objectives

• Provide an overview of the evolution of telecommunications as well as a review of its basic principles
• Describe the structure of PDH, SDH and SONET as well as their network architecture including customer, loop and office equipment
• Present the limitations of PDH
• Provide an overview of different facilities of SDH
• Give a description of SONET
• Explore the new life for legacy SDH network by explaining the Generic Framing Procedure (GFP), the virtual concatenation and the Link Capacity Adjustment Scheme (LCAS)

Topics

Part 1: Introduction

• Evolution of telecommunications
• Review of telecommunications fundamentals
• Bandwidth and capacity
• Encoding/decoding
• Modulation/demodulation
• Multiplexing/demultiplexing
• Synchronous and asynchronous transmission

Part 2: Plesiochronous Digital Hierarchy (PDH)

• PDH multiplexing structure
• T1
• E1
• DS3

• PDH network architecture
• Customer equipment
• Loop equipment
• Office equipment

• PDH limitations

Part 3: Synchronous Digital Hierarchy (SDH)

• SDH multiplexing structure
• Containers and Virtual Containers (VC)
• SDH frame
• Section overhead
• Administrative Units (AU)
• Tributary Units (TU)
• Synchronous Transport Module-N (STM-N)
• Higher level multiplexing

• Synchronized Optical NETwork (SONET) multiplexing structure
• Tributaries and Virtual Tributaries (VT)
• Synchronous Transport Signal-N (STS-N)
• Synchronous Payload Envelope (SPE)
• Optical Carrier (OC) level

• SDH facilities
• Network topologies
• Equipment
• Synchronisation
• Protection switching

• Network management

• New life for legacy SDH networks
• Generic Framing Procedure (GFP) – mapping broadband data onto SDH frame
• Virtual concatenation – splitting bandwidth into logical groups to support the transport of variable bit data streams
• Link Capacity Adjustment Scheme (LCAS) – providing bandwidth-on-demand capability for data

Target Audience

• Telecommunications managers and personnel responsible for the planning, design, implementation, management and maintenance of digital transmission systems
• Managers looking to complement their skill-set by gaining a good understanding of PDH and SDH transmission as well as SONET

Methodology

Our Training Programs combine expert presentations, workshops, case studies and discussions on real-life situations faced by participants. Complete training material is provided to all participants for future reference and follow-up action plans.
