2.3 TYPICAL APPLICATION

The 2112-CO and 2112-CP work together to create an extension between 2 peer Ethernet LANs with all the benefits of MAC bridging. The following diagram shows a typical application

3.0 INSTALLATION

The Model 2112 requires no configuration. You only need to con- nect the Ethernet interface, line interface between the units and power. This section describes these connections.

3.1 CONNECTING THE TWISTED PAIR LINE INTERFACE

The Model 2112 supports communication between two peer Ethernet LAN sites at a distance up to 3.6 miles (5.8 km) over 24AWG (.5mm) twisted pair wire. Follow the steps below to successfully con- nect the Model 2112 Line Interfaces.

1.These units work in pairs. One unit in the pair must be a Model 2112-CO (looks like Central Office equipment), and the other unit must be a Model 2112-CP (looks like Customer Premises equipment). It does not matter which end is the 2112-CO and which is the 2112-CP.

2.To function properly, the two Model 2112s must be connected together using twisted pair metallic wire. This twisted pair must be unconditioned, dry, metallic wire, between 19 (.9mm) and 26 AWG (.4mm). Standard dial-up telephone cir- cuits, or leased circuits that run through signal equalization equipment, or standard, flat modular telephone type cable, are not acceptable.
