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 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
5
• 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.
