1. To function properly, the two Model 2172Rs 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 Model 2172R is equipped with either an RJ-45 or a terminal block
interface jack that can be used on the CopperLINK interface. These
CopperLINK interfaces are a two-wire interface. Observe the signal/
pin relationships on the Model 2172R's CopperLINK interface jacks.
The RJ-45 connector on the Model 2172R's twisted pair interface is
polarity insensitive and is wired for a two-wire interface. The signal/pin
relationship is shown in Figure 3.

The terminal block connector on the Model 2172R's twisted pair interface
is polarity insensitive and is wired for a two-wire interface. The signal/pin
relationships is shown in Figure 4.
