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-REX 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.
