In DCE mode, the synchronous serial interface supports the clock{ dceclk1 | dceclk2 | dceclk3 } command.DescriptionUse the clock command to set clock selection mode for the synchronous serial interface.Use the undo clock command to restore the default.By default, on a synchronous serial interface, the DTE-side clock is dteclk1 and the DCE-side clock isdceclk1.This command does not take effect when X.21 DTE cables are used. The DTE-side clock onsynchronous serial interfaces is DTE clock option 3 (dteclk3).A synchronous serial interface can operate as DCE or DTE.z As DCE, the interface provides DCEclk clock to the DTE.
