1.1 RADIO AND TV INTERFERENCE  
The Model 2156 or 2157 generate and use radio frequency energy, and  
if not installed and used properly—that is, in strict accordance with the  
manufacturer’s instructions—may cause interference to radio and televi-  
sion reception. The Models 2156 and 2157 have been tested and found  
to comply with the limits for a Class A computing device in accordance  
with specifications in Subpart B of Part 15 of FCC rules, which are  
designed to provide reasonable protection from such interference in a  
commercial installation. However, there is no guarantee that interference  
will not occur in a particular installation. If the Model 2156 or 2157 does  
cause interference to radio or television reception, which can be deter-  
mined by disconnecting the unit, the user is encouraged to try to correct  
the interference by one or more of the following measures: moving the  
computing equipment away from the receiver, re-orienting the receiving  
antenna and/or plugging the receiving equipment into a different AC out-  
let (such that the computing equipment and receiver are on different  
branches).  
1.2 CE NOTICE  
The CE symbol on your Patton Electronics equipment indicates that it is  
in compliance with the Electromagnetic Compatibility (EMC) directive  
and the Low Voltage Directive (LVD) of the European Union (EU). A Cer-  
tificate of Compliance is available by contacting Technical Support.

The Models 2156 and 2157 are not intended to be con-  
nected to the public telephone network.  
Caution  
1.3 SERVICE

2.2 DESCRIPTION  
The Patton Electronics CopperLink Ethernet Extenders provide high-  
speed LAN connections between peered Ethernet LANs, remote PCs, or  
any other network enabled 10/100Base-T device.  
Operating in pairs, a Model 2156 or 2157 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 Ether-  
net Extenders. They automatically add and delete MAC addresses, only  
passing packets across the CopperLink line that are meant for the remote  
peered LAN.

Figure 1. Typical application  
The 2157/L and 2157/R work together to create a transparent extension  
between two peered Ethernet LANs. Figure 1 shows a typical point-to-  
point application.

can be installed quickly. Installation consists of the following:  
• Connect the line interface between the units (refer to section 3.1,  
“Connecting the Twisted-Pair Line Interface” on page 7)  
Note See Figure 2 for the rear-panel connectors locations.  
• Connect the Ethernet interface (refer to section 3.2, “Line Interface—  
Connecting the 10/100Base-T Ethernet Interface” on page 8).  
• Connect the power plug (refer to section 3.3, “Connecting Power” on  
page 10).

3.1 CONNECTING THE TWISTED-PAIR LINE INTERFACE  
The Models 2156 and 2157 support communication between two peer  
Ethernet LAN sites over a distance greater than 30,000 ft (9,144 m) over  
24 AWG (0.5 mm) twisted-pair wire.  
Note The Models 2156 and 2157 use an auto-rate adaption feature to  
provide the fastest data rate possible over the wire and distance  
of each Ethernet extension. The actual distance and rate  
achieved for Ethernet extension may vary depending on the  
environment and type/gauge of the wire used.  
7
 
     
Follow the steps below to connect the CopperLink interfaces.  
Note The Model 2156 or 2157 units work in pairs. One of the units  
must be a Model 2156/L (local) or 2157/L, and the other unit  
must be a Model 2156/R (remote) or 2157/R.  
1. To function properly, the two 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 Models 2156 and 2157 are equipped with an RJ-11 interface.  
The CopperLink interfaces are a two-wire interface. Observe the sig-  
nal/pin relationships on the CopperLink interface jack.  
The RJ-11 connector on the CopperLink Ethernet Extender’s twisted pair  
interface is polarity insensitive and is wired for a two-wire interface. The  
signal/pin relationship is shown in Figure 3.  
Figure 3. CopperLink Ethernet Extender (RJ-11) twisted pair line interface.  
3.2 LINE INTERFACE—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 4 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 (100 m) long.

Connecting the 10/100Base-T Ethernet Port to a Hub or PC  
The Models 2156 and 2157 are equipped with an MDI-X switch that  
enables connections to a hub (DCE) or PC (DTE) interface, thereby  
elimininating confusion over whether a straight-through or crossover  
cable is needed.  
When using a straight-through cable for connecting to a hub, the MDI-X  
switch should be in its released (DCE mode) position (see Figure 5).  
When connecting to a PC, the MDI-X switch should be pushed in to  
engage the crossover function so you won’t have to use a crossover cable

Figure 5. MDI-X switch positions  
Note If you have difficulty achieving a working connection between  
the CopperLink Ethernet Extender’s Ethernet port and the hub  
or PC, change the position of the MDI-X switch and try again.  
In its released position, the MDI-X switch enables straight-through con-  
nections (see Figure 6) or in its inserted position the MDI-X switch per-  
forms the crossover function (see Figure 7 on page 10).

3.3 CONNECTING POWER  
An external AC or DC power supply is available separately. This connec-  
tion is made via the barrel jack on the rear panel of the Models 2156 and  
2157. No configuration is necessary for the power supply (See  
Appendix B on page 17 for domestic and international power supply and  
cord options).  
3.4 POWER INPUT CONNECTOR  
The CopperLink Ethernet Extender comes with an AC or DC power supply.  
• The supplies connection to the CopperLink Ethernet Extender is a  
2.5 mm barrel receptacle with the center conductor positive (see  
Figure 6).

4.0 OPERATION  
Once the CopperLink Ethernet Extenders are properly installed, they  
should operate transparently. No user settings required. This section  
describes reading the LED status monitors.  
4.1 FRONT PANEL LED STATUS MONITORS  
The Models 2156 and 2157 feature eight front-panel LEDs that monitor  
power, Ethernet signals, and the CopperLink connection. Figure 9 shows  
the front panel location of each LED. Table 1 describes the LED functions.
