scope:

The present document defines the information model to be used at the interface between network elements and management systems, for the management of SDH radio Network Element additional specific performance monitoring parameters.

Considering that:

- ETS 300 635 defines SDH Radio specific functional blocks for transmission at STM-N data rate;

- ETS 300 785 defines SDH Radio specific functional blocks for transmission at STM-0 data rate;

- EN 301 645 defines SDH Radio Relay equipment information model for use on Q interfaces;

- ETS 300 304 defines the SDH information model for the Network Element view;

- EN 301 167, ETS 300 417, ITU-T Recommendations G.783 and G.784 define the performance monitoring architecture and requirements for generic functional blocks used also in DRRS;

- EN 301 129 defines additional radio specific performance monitoring parameters;

- ETS 300 411 defines the generic performance monitoring Information Model for SDH Network Element.

The present document defines:

- the information model for radio specific performance monitoring parameters for SDH radio 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 model for the generic performance monitoring Information Model for SDH Network Element.

The Information Model defined here (and the corresponding Message Set) is concerned with the management of network elements, 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.
