which are designed to provide reasonable protection from such interfer-
ence in a commercial installation. However, there is no guarantee that
interference will not occur in a particular installation. If the CopperLink
Ethernet Extender does cause interference to radio or television recep-
tion, which can be determined by disconnecting the unit, the user is
encouraged to try to correct the interference by one or more of the follow-
ing measures: moving the computing equipment away from the receiver,
re-orienting the receiving antenna and/or plugging the receiving equip-
ment into a different AC outlet (such that the computing equipment and
receiver are on different branches).

2.2 DESCRIPTION
The Patton Electronics CopperLink/L and CopperLink/R Ethernet
Extenders provide high-speed LAN connections between peered Ether-
net LANs, remote PCs, or any other network enabled 10/100Base-T
device.
Operating in pairs, a CopperLink/L (local) located at one end of the LAN
extension and a CopperLink/R (remote) at the other end, 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 CopperLink Ethernet Extenders.The CopperLink
Ethernet Extenders automatically add and delete MAC addresses, only

7
passing packets across the CopperLink link that are meant for the remote
peered LAN.
Figure 1. Typical application
The CopperLink/L modem and CopperLink/R modem work together to
create a transparent extension between two peered Ethernet LANs.
Figure 1 shows a typical point-to-point application.

3.0 INSTALLATION
Because the CopperLink Ethernet Extender requires no configuration, it can
be installed quickly.If you are installing a standalone unit, refer to section 3.1
“Standalone unit installation”.Otherwise, refer to section 3.2 “Rack card
installation”.
Note If asymmetric transmission or line rates other than 12.5 Mbps
are required (Model 2168 only), refer to section 4.0, “Configura-
tion (Model 2168 Only)” on page 14.
3.1 STANDALONE UNIT INSTALLATION
Do the following:
1. Connect the line interface between the units (refer to section 3.3,
“Connecting the Twisted-Pair Line Interface” on page 10)
Note See Figure 2 for the standalone unit’s rear panel arrangements.
2. Connect the Ethernet interface (refer to section 3.4, “Connecting the
10/100Base-T Ethernet Interface” on page 11).
3. Connect the power plug (refer to section 3.5, “Connecting Power”on
page 12).
Figure 2. CopperLink Ethernet Extender standalone rear panel

3.2 RACK CARD INSTALLATION
The CopperLink Ethernet Extender rack card comprised a front card and
a rear card.Do the following to install the cards into the rack chassis:
1. Slide the rear card into the back of the chassis along the metal rails.
2. Secure the rear card using the supplied metal screws.
3. Slide the front card into the chassis until you feel resistance as the
front card engages the rear card.When that happens,
gently push
the front card forward until it is fully seated in the card-edge recepta-
cle of the rear card (it should
click into place).
4. Secure the front card using the captive fasteners.
Note The Model 1001R14 chassis supports “hot swapping” of cards,
so it is not necessary to power down the rack when you install or
remove a CopperLink Ethernet Extender rack card.
Figure 3. CopperLink Ethernet Extender rack cards
5. Connect the line interface between the units (refer to section 3.3,
“Connecting the Twisted-Pair Line Interface” on page 10)
Note See Figure 3 for the rack card’s panel arrangements.

6. Connect the Ethernet interface (refer to section 3.4, “Connecting the
10/100Base-T Ethernet Interface” on page 11).
3.3 CONNECTING THE TWISTED-PAIR LINE INTERFACE
The CopperLink Ethernet Extender supports communication between
two peer Ethernet LAN sites over a distance of up to 6,000 ft (1.83 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 CopperLink Ethernet Extenders
interfaces.
Note The CopperLink units work in pairs.One of the CopperLink units
must be an L (local), and the other unit must be an R (remote).It
does not matter which end is the L and which is the R.The link is
always initiated by the R. As long as the L is powered on, the R
can establish a link by being powered on or by having its power
reset.
1. To function properly, the two CopperLink 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 CopperLink Ethernet Extenders are equipped with two interface
jacks that can be used on the CopperLink interface, an RJ-45 or a ter-
minal block.These CopperLink interfaces are a two-wire interface.
Observe the signal/pin relationships on the CopperLink Ethernet
Extender's CopperLink interface jacks.
The RJ-45 connector on the CopperLink Ethernet Extender's twisted
pair interface is polarity insensitive and is wired for a two-wire inter-
face.The signal/pin relationship is shown in Figure 4.

3.4 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 6 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 long.

Connecting the 10/100Base-T Ethernet Port to a Hub
The CopperLink Ethernet Extender 10/100Base-T interface is configured
as DTE (Data Terminal Equipment), just like a 10/100Base-T network
interface card in a PC.Therefore, it “expects” to connect to a
10/100Base-T Hub using a straight-through RJ-45 cable.Figure 7 dia-
grams the cable wiring for connecting the CopperLink Ethernet Extender
to a 10/100Base-T hub.
Figure 7. Wiring diagram for connecting the CopperLink Ethernet Extender to a 10/100Base-
T hub
Connecting the 10/100Base-T Ethernet Port to a PC (DTE)
The CopperLink Ethernet Extender 10/100Base-T interface is configured
as DTE (Data Terminal Equipment).If you wish to connect the Copper-
Link Ethernet Extender to another DTE devices such as 10/100Base-T
network interface card in a PC (or CopperLink Ethernet Extenders in a
back-to-back arrangement), you must construct a 10/100Base-T cross-
over cable as shown in Figure 8.

4.2 CONFIGURING DIP SWITCH S1
DIP switch S1 is where you configure the CopperLink line rate, symmet-
ric or asymmetric, Ethernet full auto negotiation capability (100Base-T
full or half duplex, 10Base-T full or half duplex) or limited auto sense
(only 100Base-T half duplex, 10Base-T full or half duplex).
Switch S1-1: Ethernet Auto Sense
Use switch S1-1 to configure the unit for full auto sense capability or lim-
ited auto sense capability.Full Auto sense capability consists of standard
Ethernet Auto sensing (100BaseT full duplex, 100BaseT half duplex,
10BaseT full duplex, and 10BaseT half duplex). Limited Auto sensing
capability consists on only auto sensing for 100BaseT half duplex,
10BaseT full duplex, and 10BaseT half duplex.The limited auto negotia-
tion feature is used when an Ethernet device does not comply with IEEE
802.3x (back pressure flow control) at 100M full duplex.
Switches S1-2 and S1-4: Data Rate
Use switches S1-2 and S1-4 to configure the CopperLink line rates.
