Router - DTE / DCE

A DTE (Date Terminating Equipment) cable is the normal cable you should use. Being DTE you should expect the other end to provide clocking.
A DCE (Data Communication Equipment) means that this device must provide the clocking on the wire.

If your device is the DCE, you must provide clocking using the clock rate command.
