Software in the switch allows you to configure access rate, clocking and protocol-related
parameters. Additional software commands allow you to view status at the
WSX board, port,
or protocol 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 or PPP connection level.
Back-to-Back WSX Using T1 Ports
WAN switching modules may be connected “back-to-back” without an intervening Frame
Relay network or switch. Because the T1 port internally provides a DSU/CSU function, an
external DSU/CSU is not required. Such connections are made by using private leased lines,
such as
T1 lines, instead of public Frame Relay networks, usually over large geographic
distances.
