LAN Connections Over a WAN
When LANs are distributed over a large physical area (such as within a
metropolitan area) or cabling is not available between sites, you can lease
appropriate unloaded copper pairs from a local carrier for LAN connectivity.
For transport over public networks, you can connect the public T1 network
(DSX-1 signal) to the LAN through desktop units with CSU/DSX-1 interface
cards and the Campus-REX2 in a desktop unit. This application, as shown in
the following figure, simplifies access to public high-speed WANs for LAN
connectivity to remote sites.
