 # This example configuration outlines how to configure the srsRAN Project CU/DU to use an O-RU and split 7.2. This is specifically for use
 # with the Benetel R550 RU. This config will create a single TDD MIMO cell transmitting in band 78, with 20 MHz bandwidth and 30 kHz sub-carrier-spacing.
 # The parameters used to configure the RU are found in the `ru_ofh` sub-section. This configuration makes used of the OFH Lib from SRS to enable split 7.2.
