How this publication is organized

In a continuous effort to improve our documentation, we are preparing its delivery through the web.This leads to a new global organization of the Nortel technical publications.

The information is divided into modules, with each module containing elementary information, suchas a procedure to replace a particular equipment, or a description of a particular component.

The modules are designed in order to deliver just enough information to provide the user with thesolution required to perform a particular task.

These modules will be delivered on CD-ROMs or through the web. The user can access thisinformation by browsing, by navigating from one module to another, or by using a search engine.

This NTP has been written as a series of modules which are arranged one after the other in logicalorder. The table of contents helps you to access the right module.

The first set of modules lists the definitions of terms used in NTPs and courseware that are specificto UMTS.

The second set of modules lists the abbreviations used in NTPs and courseware that are specific toUMTS. The expanded term is given for each abbreviation.
