Interface Module

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
