Invert Transmit-Clock; Loopback (Serial Interface) - 3Com 3C13618 Command Reference Manual

3.1.11 invert transmit-clock

Syntax
invert transmit-clock
undo invert transmit-clock
View
Serial interface view
Parameter
None
Description
Using the invert transmit-clock command, you can enable the invert transmit clock
on the synchronous serial interface at the DTE side. Using the undo invert
transmit-clock command, you can disable the invert transmit-clock.
By default, Invert transmit-clock disabled when the synchronous serial interface acts
as the DTE.
In some circumstances, the transmit clock on the serial interface of the DTE side is
inverted to eliminate the delay for half a clock cycle. This command is only valid for
some clock signals provided by some special DCE. The transmit clock should not be
inverted for normal applications.
For related commands, see physical-mode, clock.
