Serial Connectors and Flex-WAN Cables

DTEs include mainframes and automatic teller machines. DCEs include
modems and CSU/DSUs.
A DCE must always connect to a DTE, and vice versa. If you need to
connect a DTE to a DTE, or a DCE to a DCE, you can use a crossover cable
between the two devices.
For example, a SuperStack II bridge/router is a DTE. To connect the
bridge/router to another DTE, such as a mainframe, use a crossover
Flex-WAN DCE cable. The DCE cable has a DCE connector on the end
that connects to the mainframe (see Figure 29).
Figure 29
Connecting the Bridge/Router to a DTE Using a DCE Cable
To connect the bridge/router to a DCE, such as a modem, use a
straight-through Flex-WAN DTE cable. The DTE cable has a DTE connector
on the end that connects to the modem (see Figure 30).
