Note
Inverting the Clock Signal
Systems that use long cables or cables that are not transmitting the TxC (clock) signal might experience high
error rates when operating at higher transmission speeds. If a 4-Port Serial Interface SPA port is reporting a
high number of error packets, a phase shift might be the problem; inverting the clock might correct this phase
shift.
When the EIA/TIA-232 interface is a DTE, the invert-txclock command inverts the TxC signal the DTE
receives from the remote DCE. When the EIA/TIA-232 interface is a DCE, the invert-txclock command
inverts the clock signal to the remote DTE port. Use the no invert-txclock command to change the clock signal
back to its original phase.
Use the following commands when inverting the clock signal:
PurposeCommand
Enters global configuration mode.Router# configure terminal
Selects the interface to configure and enters interface
configuration mode.
Router(config)# interface serial slot/subslot/port
Inverts the transmit clock signal. When the
EIA/TIA-232 interface is a DTE, the invert txclock
command inverts the TxC signal the DTE receives
from the remote DCE. When the EIA/TIA-232
interface is a DCE, the invert txclock command
inverts the clock signal to the remote DTE port.
The no form of this command changes the clock
signal back to its original phase.
Router(config-if)# invert txclock
Invert the data signal.
The no form of this command disables the inversion
of the data stream.
Router(config-if)# invert data
