19 (0.9mm) and 26 AWG (0.4mm). Leased circuits that run through
signal equalization equipment are not acceptable.
2. The Model 1173R is equipped with either an RJ-45 or a terminal block
interface jack that can be used on the interface. These interfaces are
a two-wire interface. Observe the signal/pin relationships on the
Model 1173R's interface jacks.
The RJ-45 connector on the Model 1173R's twisted pair interfa ce 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 1173R's twisted pair interface
is polarity insensitive and is wired for a two-wire interface. The signal/pin
relationships is shown in Figure 4.
