ITU-T G.774.2 PDF

SDH Payload Configuration Functions are used to configure the various SDH adaptation functions.

Modification of the SDH payload structure is done by applying an action on relevant managed objects.

These actions are included by subclassing of existing G.774 managed object classes. The new objects defined in this Recommendation supersede those defined in ITU-T G.774.2 (1994).

Structure of this Recommendation

Clause 5.1 provides an overview of the SDH Payload Configuration information model. Clauses 6 to 12 describe the information model using the notation mechanisms defined in ITU-T X.722 Guidelines for the Definition of Managed Objects. Clauses 13 and 14 describe the connectivity pointer constraint rules and the subordination rules applicable to the termination point fragment. Clause 15 contains the syntax definitions of the information carried in the protocol using Abstract Syntax Notation One (ASN.1) defined in ITU-T X.680-X.683. Naming and Inheritance are illustrated in informative Appendix I.
