Flex-WAN Serial
Connectors and
Serial Cables
The Flex-WAN serial connectors on the switch can be connected to DTE
and DCE devices with the following interfaces:
■
RS-232
■
V.35
■
X.21
■
RS-449
■
RS-530 (DCE only)
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 PathBuilder switch is a DTE. To connect the switch 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).
