scope:

The present document describes the SDH radio specific functionalies defined in ETS 300 635 [2] and ETS 300 785 [3] using the EN 300 417 series [5] methodology. The document contains the specification and the amendments necessary to EN 300 417 series [5] in order to take into account radio requirements. Considering that: - ITU-R Recommendation F.750 [1] defines SDH Radio specific functional blocks for transmission at STM-n and sub-STM-1 (STM-0) data rate. - ETSI ETS 300 635 [2] based on ITU-R Recommendation F.750 [1] defines SDH Radio specific functional blocks for transmission at STM-n data rate. - ETSI ETS 300 785 [3] based on previous ITU-R Recommendation F.750 [1] defines SDH Radio specific functional blocks for transmission at sub-STM-1 data rate. - ETSI EN 300 417 [5] defines the generic functional requirements for Synchronous Digital Hierarchy (SDH) equipment. This present document defines the layer and their atomic function for SDH radio equipment.
