Combined Frame Relay with ISDN Backup
In a typical configuration, the
WSX
occupies either a slot in a switch chassis or a submodule
on an OmniAccess 512. Because it is compatible with Omni Switch/Router any-to-any
switching and
switching and
VLAN
architecture, you can switch other topologies in the
LAN
to Frame Relay
or PPP. The
WSX
connects to a
DSU/CSU
or T1 multiplexer through a serial cable. The
following diagram shows a typical
WSX
setup using a 56 kbps Frame Relay line (up to 2 Mbps
access rates are supported)
Refer to the Chapter 29, “Managing Frame Relay,” and Chapter 56, “Backup Services,” for
details on how to implement this configuration.34
