Alcatel Carrier Internetworking Solutions Omni Switch/Router - Manual (Page 874)

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.
