    1 Introduction 1.1 Scope This document merges the basic ATM transport principle. It describes protocol stacks, transmission resources, transmission resource management (TRM), and associated parameters.

    1.2 Intended Audience This document is intended for:

    z Personnel who are familiar with WCDMA basics z Personnel who need to understand ATM transport z Personnel who work with Huawei products

    1.3 Change History This section provides information on the changes in different document versions.

    There are two types of changes, which are defined as follows:

    z Feature change: refers to the change in the ATM transport feature. z Editorial change: refers to the change in wording or the addition of the information that was not

    described in the earlier version.

    Document Issues The document issues are as follows:

    z 01 (2010-10-15) z Draft (2010-03-30)

    01 (2010-10-15) This is the document for the first commercial release of RAN12.0.

    Compared with issue Draft (2010-03-30) of RAN12.0, this issue optimizes the description.

    Draft (2010-03-30) This is the draft of the document for RAN12.0.

    This is a new document.
