Supported Protocols
The WAN switching modules support both Frame Relay and synchronous Point-To-Point
Protocol (PPP). For ISDN signalling protocols, the modules support D-channel signalling (see
Chapter 32, “Managing ISDN Ports.” For more details on implementing these protocols, see
Chapter 29, “Managing Frame Relay,” and chapter 30, “Point-to-Point Protocol.”
Application Examples
This section provides several examples of the types of WAN networking possible using WAN
switching modules.
Frame Relay WSX Using Serial Ports
In a typical configuration, the WSX occupies either a slot in a switch chassis or a submodule
in an OmniAccess 512. Because it is compatible with Omni Switch/Router any-to-any
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).
WSX Frame Relay Configuration Using Serial Ports
For serial ports, the WSX supports automatic detection of cable types. It also supports internal,
external, and split clocking.
