Campus-RS REX2

Ethernet Bridge/Router

Interface Module

CAREX2

The Campus-RS™REX2 (Remote Ethernet eXpress) is an interface module that installs

directly into a Campus-RS remote device or Campus-RS Star concentrator and provides

interconnectivity of geographically dispersed Ethernet LANs within a private enterprise

network. The Campus-RS REX2 functions as a full-bandwidth Ethernet remote bridge, or a

static or dynamic IP router, using the existing copper infrastructure as the transmission

medium to provide repeaterless connectivity between LAN segments up to 4.6 Mbps.

The Campus-RS REX2’s robust architecture eliminates the need for other bridges, routers and

DSU/CSUs. It provides a 10/100 auto sensing port, an embedded SNMP agent and IEEE 802.1d

transparent MAC-layer bridging. HDLC and PPP encapsulation options and VLAN pass through

IP routing allow interoperability with other internetworking devices. The Campus-RS REX2 can

be used to extend subnetworks to remote sites within a private enterprise network, or to

connect to the public T1/E1 wide area network (WAN) to internetwork sites separated by

greater distances.

Features:

• Eliminates need for costly bridges

and routers

• Simple installation and management

• Maintains logical network partitioning

• VLAN passthrough

• 10/100 ethernet auto sensing

• Routing, static, dynamic

• Bridging and spanning tree

• 4.6 Mbps WAN speed

• Fast code download

- FTP download

- TFTP code recovery

• Telnet
