The present document defines the information model to be used at the interface between Network Elements (NEs) and
management systems, for the management of equipment which use the Plesiochronous Digital Hierarchy (PDH).
The present document defines:
- the information model for network elements using PDH multiplexing, including PDH interfaces of Synchronous
Digital Hierarchy (SDH) network elements.
The present document does not define:
- the protocol stack to be used for message communication;
- the network level management processes;
- the application contexts;
- the conformance requirements to be met by an implementation of this information model;
- information models for other systems or equipment.
The information model defined in the present document (and the corresponding message set) is concerned with the
management of NEs, the equipment by which they are implemented and the functions contained within them. More
precisely, it applies to an equipment domain visible at the element manager to element interface and is only concerned
with information available within that domain. Information proper to the domain of a network level management
process is not included within this model.
