Fixed Radio Systems; Point-to-point equipment; High capacity digital radio relay systems carrying STM-4, 4 × STM-1 or 2 × STM-1 signals in bands with 55/56 MHz channel spacing

Scope

The present document specifies the minimum performance parameters for terrestrial digital fixed service radio communications equipments operating in the 15 GHz to 38 GHz frequency band intended to be used for point-to-point connections in local and regional networks at data rates between 2 × STM-1 (transported by one carrier) and 4 × STM-1 or STM-4 (transported by two 2 × STM-1 carriers). Harmonized channel spacings of 56 MHz are not available in frequency bands below 15 GHz at the drafting date of the present document. However, the present document can be considered as a guideline where national frequency plans allow the use of 55/56 MHz channel spacing in other frequency bands, or where an allocation of two contiguous 28 MHz channels is possible.
