Follow the steps below to connect the CopperLink interfaces.
Note The Model 2156 or 2157 units work in pairs. One of the units must be a Model 2156/L (local) or 2157/L, and the other unit must be a Model 2156/R (remote) or 2157/R.
1.To function properly, the two 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 Models 2156 and 2157 are equipped with an RJ-11 interface. The CopperLink interfaces are a two-wire interface. Observe the sig- nal/pin relationships on the CopperLink interface jack.
The RJ-11 connector on the CopperLink Ethernet Extender’s twisted pair interface is polarity insensitive and is wired for a two-wire interface. The signal/pin relationship is shown in Figure 3.

3.2LINE INTERFACE—CONNECTING THE 10/100BASE-T ETHERNET INTERFACE
The shielded RJ-45 port labeled Ethernet is the 10/100Base-T interface. This port is designed to connect directly to a 10/100Base-T network. Figure 4 shows the signal/pin relationships on this interface. You may connect this port to another Ethernet device via a Type 4 or Type 5 cable that is up to 328 ft (100 m) long.
