Scope of N2171

• Scope– defines an ANT(Access Network Transport) on the background of the

Recs. G.902 and GII Y.100 series

– provides an overview of the existing ANT related standards released and/or prepared by the ITU and other standardization bodies.

• Main purpose– Which standards exist

– Topics/standards under study/development

– Lack of standards

– Duplication and/or overlap

– Market needs

– Priorities

ANT Reference Model

4• Logical represen

ANT Interface

• SNISn : between Service Function and Access Network (n- seq. number)

• SNICn : between Core Network and Access Network ( n- seq. number)

• XNIXYn : between Access Network and CPN (x: type of access technology / y: medium)

• Ln : between Access Networks

• Qn : between Access Network and Management Agent/Network

ANT Scenarios

6

• The matrix will be updated through liaison to ITU-T, ITU-R, and standards organizations outside the ITU.

• It is planned to eventually replace this manual method for presenting the matrix of standards with a web-based approach.
