WSX-SC
The WSX-SC supports 4 or 8 serial ports, each of which can provide access rates from 9.6
Kbps to 2 Mbps. The 4-port version is referred to as the WSX-SC-4W , and the 8-port version is
referred to as the WSX-SC-8W . The WSX-SC supports STAC hardware compression and three
types of clocking (internal, external, and split). See WSX-SC Technical Specifications on page
3-30 for more information.
The WSX-SC 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-SC 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-SC board 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-SC 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.
