This section describes example applications for the PathBuilder S21x switch.
The PathBuilder S21x switch supports multiprotocol encapsulation of IP traffic and
legacy serial protocols over frame relay as specified by RFC 1490. As shown in
Figure 1-2, a SNA cluster controller connects to a serial port on the PathBuilder S21x
switch and the Ethernet LAN connects to the 10BaseT Ethernet port. The PathBuilder
S200 series switch is fully interoperable with third party routers via RFC 1490.

As shown in Figure 1-3, the PathBuilder S21x switch can support encapsulation of
video and legacy protocol over frame relay. This use of PathBuilder S21x switch
suits banking applications such as Automated Bank Machines (ABMs). With Dial on
Demand software feature enabled, the PathBuilder S21x switch initiates a connection
only when there is data transfer, i.e. only for the duration of a bank transaction. The
RemoteVu Daughtercard can capture video and send video streams to the central
bank's security system.
