5.3 MAKING INTERFACE CONNECTIONS
The Patton K Module may be connected to G.703/G.704 ports
using a single 120 ohm RJ-48C or a dual 75 ohm coax (BNC). The
Patton K Module rear panels and the location of these connectors are
show below in Figure 4.
The Patton K Module is equipped with a single RJ-48C jack for
connections to a 120 ohm twisted pair G.703/G.704 network interface.
If your G.703/G.704 network terminates via RJ-48C, use the diagram
below and the table on the following page to make the proper connec-
tions. The connector pinout and signals are shown in Figure 5, below.
Use the following connection diagram to connect the 120 ohm
G.703/G.704 network channel.

The Patton K Module is also equipped with dual female BNCs (TX
and RX) for connection to a 75 ohm dual coax G.703/G.704 network
interface. If your G.703/G.704 network terminates via dual coaxial
cable, use the diagram below to make the proper connections. The
connector pinout and signals are shown in Figure 6, below.
NOTE: The outer conductor of the coax cables are isolated
from system earth ground.
