WSX-S-2W

The WSX-S-2W supports two (2) serial ports, which can provide access rates from 9.6 Kbps to
2 Mbps. The WSX-S-2W also supports three types of clocking (internal, external, and split). See
WSX-S-2W Technical Specifications on page 3-27 for more information.
♦ Note ♦
The WSX-S-2W does not support hardware compres-
sion.
The WSX-S-2W can sense and auto-configure for any of five serial cable types (RS-232, V.35,
X.21, RS-530, and RS-449). A WSX-S-2W port is normally considered a physical DTE device. It
can be turned into a physical DCE device—for speed or clocking purposes— by plugging in a
DCE cable. The WSX-S-2W senses whether a DCE or DTE cable is connected.
Software in the switch allows you to configure parameters for the Frame Relay or Point-to-
Point Protocol (PPP). Software commands allow you to view the status of the WAN connec-
tion at the WSX-S-2W board, port, or virtual circuit level. Extensive statistics are provided at
each level. Software commands for Frame Relay are described in Chapter 29, “Managing
Frame Relay”; commands for PPP are described in Chapter 30, “Point to Point Protocol.”
With the optional HRE-X you can increase routing performance to 1.5 million packets per
second per module and up to 12 Mpps in a fully-loaded 9-slot chassis.
