Use the undo eliminate-pulsecommand to restore the default, eliminating the pulses with a width less than 1.472 us.

n When the baud rate of the interface is 115,200 bps, you cannot configure this command. After you configure this command, the baud rate of the interface cannot be set to 115,200 bps.

This command is restricted to the 8ASE and 16ASE interface cards and modules.

Example # Eliminate the pulses with a width less than 3.472 us on interface Async 1/0.

Description Use the idle-markcommand to set the line idle code of the synchronous serial interface to 0xFF.

Use the undo idle-markcommand to restore the default, that is, 0x7E.

In most cases, a synchronous serial interface uses 0x7E to identify the idle state of the line. You may need to set the line idle code to 0xFF however to interoperate with devices that use 0xFF (high level of all ones) as line idle code.

Example # Set the line idle code of synchronous serial interface 2/0 to 0xFF.

<Sysname> system-view
