• Can 2 DTE devices communicate? Answer : No

For Lab Setup : convert one Router to act as a DCE device. The cable will have a DCE end and a DTE end

• To check : Look for the label on the cable

• The DCE end of the cable connected to the router’s interface should be made as DCE by giving a CLOCKRATE command in the interface mode.
