There are два types of devices that can communicate over a serial interface: DCE и DTE. A DCE provides a physical connection to a network и forwards traffic. A DTE connects to a network through a DCE device. Typically, a DTE device is connected to a DCE device (or vice versa) rather than another DTE device. Check the documentation that ships with your serial device to determine if it is a DTE or DCE device. If you cannot find the information in the serial device documentation. This table summarizes serial devices that can be connected to the router serial port и whether the device is considered a DTE or DCE device. The Cisco 805 router is a DTE device by default.
