Configuring Serial Interfaces on a Cisco Router

Serial interfaces are used to communicate with other local Cisco Routers or to establish a connection to the WAN through a CSU/DSU device. The required steps are almost identical to the configuration of any other interface’s with a few exceptions. When connecting two Cisco routers directly with a DCE/DTE cable, the router which has the DCE end of the cable connected to it has to be configured to dictate the clock rate. It is essential for proper communication.
