Appendix A: An SDH overview

Overview

...................................................................................................................................................................................................................................

Purpose

This chapter briefly describes the Synchronous Digital Hierarchy (SDH).

Synchronous Digital Hierarchy

In 1988, the ITU-T (formerly CCITT) came to an agreement on the Synchronous
Digital Hierarchy (SDH). The corresponding ITU-T Recommendation G.707 forms the
basis of a global, uniform optical transmission network. SDH can operate with
plesiochronous networks and therefore allows the continuous evolution of existing
digital transmission networks.

The major features and advantages of SDH are:

•

Compatibility of transmission equipment and networks on a worldwide basis

•

Uniform physical interfaces

•

Easy cross connection of signals in the network nodes

•

Possibility of transmitting PDH (Plesiochronous Digital Hierarchy) tributary signals
at bit rates commonly used at present

•

Simple adding and dropping of individual channels without special multiplexers
(add/drop facility)

•

Easy transition to higher transmission rates

•

Due to the standardization of the network element functions SDH supports a
superordinate network management and new monitoring functions and provides
transport capacity and protocols (Telecommunication Management Network, TMN)
for this purpose in the overheads of the multiplex signals.

•

High flexibility and user-friendly monitoring possibilities, e.g. end-to-end
monitoring of the bit error ratio.

Purpose of SDH

The basic purpose of SDH is to provide a standard synchronous optical hierarchy with
sufficient flexibility to accommodate digital signals that currently exist in today’s
network, as well as those planned for the future.
