A configuration command that modifies the parameters of the reference clock of the SCU. In this command, Subrack No. uniquely identifies an SCU reference clock.
1. In the GMPS, the reference clock of the GSCU must be that of the GGCU. In the GEPS, the reference clock of the GSCU must be that of the GGCU. In the GTCS, the reference clock of the GSCU must be the line clock. In this case, you must ensure the GTCS is configured with the line clock.
2. If you configure the SCU reference clock as invalid, the services are affected due to lack of a uniform reference clock for the local subrack.
