2.2 DESCRIPTION
The Patton Electronics Model 2172A CopperLink modems provide high-
speed LAN connections between peered Ethernet LANs, remote PC’s, or
any other network enabled 10/100Base-T device.
Operating in pairs, one Model 2172A is configured as the (L) Local unit
located at one end of the LAN extension and the other Model 2172A is
configured as the (R) Remote unit at the other end. The Model 2172A is
configured as a L or R via the switch on the bottom of the unit.These units
can automatically forward LAN broadcasts, multicasts, and frames across
a 2-wire voice-grade twisted-pair link. The data is passed transparently
(unmodified) through the 2172As. The 2172As automatically add and
delete MAC addresses, only passing packets across the CopperLINK link
that are meant for the remote peered LAN.

Figure 1. Typical application
The pair of 2172A models work together to create a transparent extension
between two peered Ethernet LANs. Figure 1 shows a typical point-to-
point application.

perature, flammability, and mechanical serviceability.
The Model 2172A supports communication between two peer Ethernet
LAN sites over a distance of up to 4,250 ft (1.3 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 Model 2172A CopperLINK Inter-
faces.
Note The Model 2172A units work in pairs. One of the units must be
configured as a (L) Local unit, and the other unit must be config-
ured as a (R) Remote unit. It does not matter which end is the L
and which is the R. The link is always initiated by the R unit. As
long as the L unit is powered on, the R unit can establish a link
by being powered on or by having its power reset.

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