This Supplement is an information document and is intended as a roadmap and a source of references for documents related to IMT-2000 specifications from ITU-T as well as from sources outside the ITU (e. g. 3GPPs and SDOs.) The list of documents contained in this Supplement should therefore be treated as bibliographic references. The scope includes any relevant standards that are targeted toward the specification of IMT-2000 systems. NOTE - This version of this Supplement (Issue 2) includes information up to November, 2000 whereas the previous version (Issue 1) included information up to February, 2000. Clause 7 has been substantially extended and Clauses 8 and 9 have been revised and updated. Updates will be reflected in future versions.
