3.3CONNECTING THE TWISTED-PAIR LINE INTERFACE

The CopperLink Ethernet Extender supports communication between two peer Ethernet LAN sites over a distance of up to 6,000 ft (1.83 km) over 24 AWG (0.5 mm) twisted-pair wire.

Note Actual distance and link performance may vary depending on the environment and type/gauge of wire used.

Follow the steps below to connect the CopperLink Ethernet Extenders interfaces.

Note The CopperLink units work in pairs. One of the CopperLink units must be an L (local), and the other unit must be an R (remote). It does not matter which end is the L and which is the R. The link is always initiated by the R. As long as the L is powered on, the R can establish a link by being powered on or by having its power reset.

1.To function properly, the two CopperLink Ethernet Extenders must be connected together using twisted-pair, unconditioned, dry, metal wire, between 19 (0.9mm) and 26 AWG (0.4mm). Leased circuits that run through signal equalization equipment are not acceptable.

2.The CopperLink Ethernet Extenders are equipped with two interface jacks that can be used on the CopperLink interface, an RJ-45 or a ter- minal block. These CopperLink interfaces are a two-wire interface. Observe the signal/pin relationships on the CopperLink Ethernet Extender's CopperLink interface jacks.

The RJ-45 connector on the CopperLink Ethernet Extender's twisted pair interface is polarity insensitive and is wired for a two-wire inter- face. The signal/pin relationship is shown in Figure 4.
