The present document defines the additional specific performance monitoring functional architecture and requirements
to be used for management of Digital Radio Relay Systems (DRRS) which use the Synchronous Digital Hierarchy
(SDH).
Considering that:
- ETS 300 635 [4] and ITU-R Recommendation F.750 [3] define the SDH radio specific functional blocks for
transmission at STM-n data rate;
- ETS 300 785 [5] and ITU-R Recommendation F.750 [3] define the SDH radio specific functional blocks for
transmission at Synchronous Transport Module 0 (STM-0) data rate;
- EN 301 167 [6], ETS 300 417 [7], ITU-T Recommendations G.783 [1] and G.784 [2] define the performance
monitoring architecture and requirements for generic functional blocks used on SDH DRRS and other SDH
equipment;
- ITU-T Recommendation M.3010 [8] defines the standardized logical and functional Telecommunication
Management Network (TMN) architecture.
The present document defines:
- the specific performance primitives and events to be used for performance management of radio specific
functional blocks;
- the general requirements for history treatment associated to each performance event;
- the general requirements for thresholding treatment associated to each performance event;
- the specific transmission quality information which is required for maintenance purpose.
The present document does not define:
- the F interface performance monitoring;
- the performance monitoring related to non radio specific functional blocks;
- the information model to be used on Q interface which is on the study in TC TMN, (ES 201 652 [18]).
- the protocol stack to be used for the message communication function;
- any radio specific additional performance parameter to be used at network level management.
The present document applies on each SDH DRRS independently of the transmission data rate supplied (STM-n or
STM-0).
