196CHAPTER 11: FUNDAMENTAL SERIAL INTERFACE CONFIGURATION COMMANDS

Description Use the invert receive-clockcommand to invert the receive-clock signal on the DTE-side synchronous serial interface.

Use the undo invert transmit-clockcommand to restore the default.

By default, receive-clock signal inversion is disabled on DTE-side synchronous serial interfaces.

Sometimes, you may need to invert the receive-clock signal on a DTE-side serial interface to eliminate the half clock-period delay on the line. This command is necessary only for some special DCE devices. In common applications, clock must not be inverted.

Related command: physical-mode,invert transmit-clock,clock (serial interface view).

Example # Invert the receive-clock on DTE-side synchronous serial interface 2/0.

[Sysname] interface serial 2/0

[Sysname-Serial1/0] invert receive-clock
