prSSH ETS 300 786:1998 ed.1

Transmission and Multiplexing (TM); Digital Radio Relay Systems (DRRS); Sub-STM-1 DRRS operating in the 13 GHz, 15 GHz and 18 GHz frequency bands with about 14 MHz co-polar channel spacing

Scope

This ETS specifies the minimum performance parameters for terrestrial fixed services radiocommunications equipment, as given below, for operation in the 13 GHz (12,75 GHz to 13,25 GHz), 15 GHz (14,5 GHz to 15,35 GHz ) and 18 GHz (17,7 GHz to 19,7 GHz) frequency bands. This ETS covers equipment for the transmission of sub-STM-1 digital signals with a VC3 payload capacity. The standardization of sub-STM-1 radio systems for 13 GHz, 15 GHz and 18 GHz bands has been prepared to ensure the compatibility with the existing plesiochronous and the new synchronous systems concerning frequency plans and performance.
