10、s with the control of the adaptation functions which sit between the layers of the SDH architecture, see ITU-T Recommendation G.805. It does not cover the control of SDH cross-points which come under the “fabric” managed object class. 2 Introduction to payload configuration The existing terrestrial
11、Recommendation on this subject is ITU-T Recommendation G.774-02 (1 993). This was extensively revised in 1996 with many of the object classes being updated to Revision 1 status, indicated by adding R1 to the end of the object class name. This Recommendation follows the 1996 practice. Traditional ter
12、restrial SDH payload configuration operations may be applied to the terrestrial SDH adaptation functions which might be found in satellite earth stations. 2.1 Satellite specific payloads Specialized adaptation equipment functions have been defined in Recommendation IT-R S. 1 I49 to support asymmetri
13、c and point-to-multipoint working in satellite systems and this Recommendation defines the corresponding payload configuration management object classes to control these specialized adaptation functions. This Recommendation is concerned with the lowest level details of the network management concept
