The present document provides an information model for the performance monitoring of Synchronous Digital
Hierarchy (SDH) network. This model describes the managed object classes and their properties for the performance
monitoring function, as defined in ITU-T Recommendation G.784 [1] and EN 301 167 [2] and as related to SDH
Network Elements (NEs). These objects are useful to describe information exchanged across interfaces defined in
ITU-T Recommendation M.3010 [3] Telecommunications Management Network (TMN) architecture for the
management of the performance monitoring function.
PDH performance monitoring functions are used to monitor specified performance events of specified termination
points managed objects as defined in EN 300 371 [4] and to report these performance data, as well as quality of service
alarms to its managing system according to a given schedule.
ITU-T Recommendation M.2120 [5] defines maintenance of transport network,
ITU-T Recommendation G.784 [1] defines the management of SDH based NE. The present document defines the object
model based on ITU-T Recommendation Q.822 [6] according to the requirements described in
ITU-T Recommendation G.784 [1], EN 301 167 [2] and ITU-T Recommendation M.2120 [5]. This model uses generic
mechanism defined in ITU-T Recommendation Q.822 [6].
The present document defines:
- an information model, as related to the performance monitoring function for the Plesiochronous Digital
Hierarchy (PDH).
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 here (and the corresponding message set) is concerned with the management of NEs,
the equipment by which they are implemen (...abbreviated)
