When installed in a Campus-RS Desktop Unit or Campus-Star chassis, the
Campus-REX functions as a remote bridge or static IP router.
You can use the Campus-REX to extend subnetworks to remote sites within
a campus. Or, for sites separated by greater distances, you can use the
Campus-REX to connect them through a public T1/E1 Wide Area Network
(WAN). See
“Point-to-Point LAN Extension” and “LAN Connections Over
a WAN” on page 1-7 for more information.
Campus-REX software provides complete main bridging tasks of learning,
forwarding, filtering, and hashing/buffer management, 802.1d Spanning Tree
protocol, 802.3 drivers, packet sequencing, segmentation and reassembly,
and other local tasks. The Campus-REX is specifically designed for
10BASE-T LANs that use unshielded twisted pair (UTP) segments with
reach of more than 100 meters and that require low-cost, high performance
connectivity.
The Campus-REX performs full-bandwidth filtering on the 10BASE-T port,
and forwarding at the selected transmission rate.
Point-to-Point LAN Extension
As organizations move or change, LANs also evolve and may become
fragmented or physically separated. The Campus-REX provides a lower-cost
alternative to other LAN-extension solutions. The Campus-REX provides a
built-in 10BASE-T LAN interface that eliminates the need for other
internetworking devices while providing 30 times the performance of other
sub-rate wireless connectivity options, as shown in the following figure.
