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.
