When DTE/DCE is using external clock source, long cables at high speed might
introduce phase shift in transmitted data and clock. Clock inversion can reduce
errors by correcting the phase shift.
Note: By default, the transmit clock is not inverted.

OOPBACK
Loopback command can be used for troubleshooting and diagnostic purpose.
When interface is configured in loopback mode, Tx data and Tx clock loop to
internal controller as Rx data and Rx clock. In the same way, Rx data and Rx
clock on line loop out on line as Tx data and Tx clock.

Command (in ICM) Description
invert-txc
This command inverts the transmit clock
to correct phase shift between the clock
and the data.
no invert-txc
The “ no ” command sets the clock to
original phase.
Command (in ICM) Description
loopback
This command configures an interface in
loopback mode.
no loopback
The “ no ” command removes the
loopback configured on the interface.
