The 

WSX

 supports automatic detection of cable types attached to universal serial ports. It also 

supports three types of 

DLCMI

 management: 

LMI

 Rev. 1.0, 

ANSI T1.617

 Annex D, and 

CCITT/

ITU-T Q.933

 Annex A.

Software in the switch allows you to configure access rate, clocking, 

DLCMI

 type, compres-

sion, and congestions controls, such as the Committed Information Rate (

CIR

). Additional soft-

ware commands allow you to view the status of the Frame Relay connection at the 

WSX

 

board, port, or virtual circuit level. Extensive statistics are provided at each level, including a 
breakdown of traffic by frame type (Ethernet, 

IP

, 

IPX

, or 

BPDU

) at the virtual circuit level.

The 

WSX

 is designed to require as little configuration as possible. It senses the cable type 

installed and automatically maps virtual circuits to virtual ports as soon as you plug in the 
cable. The 

WSX

 supports 256 Permanent Virtual Circuits (

PVCs

), which is equivalent to the 

number of virtual ports allowed in an Omni Switch/Router.

In addition, you can set up a default bridging and a default routing Group. Virtual circuits are 
automatically assigned to these Groups as soon as they are configured or learned, which 
means Frame Relay frames can be bridged or routed without user-configuration.
