    Abstract - (Show below) - (Hide below)

    This standard specifies technical parameters for a high capacity Digital Radio Relay System (DRRS) operating in frequency bands with 40 MHz channel spacing e.g. the 4 GHz, 5 GHz, U 6 GHz and 11 GHz bands. The capacity should be STM-4 or 4 STM-1 per 40 MHz RF-channel by using both polarizations in the co-channel dual polarized (CCDP) mode of operation.
