1.1 RADIO AND TV INTERFERENCE
The Model 2155 generates and uses 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 television
reception. The Model 2155 has 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.
Howev er, there is no guarantee that interference will not occur in a particular installation. If the Model 2155 does cause interference to radio or
television reception, which can be determined 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 outlet (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 Certificate of Compliance is available by contacting Technical Support.

2.2 DESCRIPTION
The Patton Electronics CopperLink Ethernet Extenders provide highspeed LAN connections between peered Ethernet LANs, remote PC’s, or
any other network enabled 10Base-T device.
Operating in pairs, a Model 2155/L (local) located at one end of the LAN
extension and a Model 2155/R (remote) at the other end, these units can
automatically forward LAN broadcasts, multicasts, and frames across a 2wire voice-grade twisted-pair link. The data is passed transparently
(unmodified) through the Ethernet Extenders. They operate as learning
bridges and automatically add and delete MAC addresses; only passing
packets across the CopperLink line that are meant for the remote peered
LAN.
5
Figure 1.
Typical application
The 2155/L and 2155/R work together to create a transparent extension
between two peered Ethernet LANs. Figure 1 shows a typical point-topoint application.
6
3.0 INSTALLATION
Because the CopperLink Ethernet Extender requires no configuration, it 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, “Connecting
10Base-T Ethernet Port to PC (DTE)” on page 8 or section section 3.3,
“Connecting 10Base-T Ethernet Port to Hub (DCE)” on page 8).
• Connect the power plug (refer to section 3.4, “Connecting Power” on
page 9).

3.1 CONNECTING THE TWISTED-PAIR LINE INTERFACE
The Model 2155 supports communication between two peer Ethernet
LAN sites over a distance greater than 5 miles (8 km) over 24 AWG (0.5
mm) twisted-pair wire.
Follow the steps below to connect the CopperLink interfaces.
Note
Model 2155 units work in pairs. One of the units must be a
Model 2155/L (local) and the other unit must be a Model 2155/R
(remote).
7
1. To function properly, 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 2155 are equipped with an RJ-45 interface. The Copper-
Link interfaces are a two-wire interface. Observe the signal/pin relationships on the CopperLink interface jack.
The RJ-45 connector on the Model 2155’s twisted pair interface is polarity insensitive and is wired for a two-wire interface. The signal/pin relationships are shown in Figure 3 below.
Figure 3.

3.2 CONNECTING 10BASE-T ETHERNET PORT TO PC (DTE)
The 10Base-T interface is configured as DTE (Data Terminal Equipment). If the Model 2155 is to to connect to another DTE device such as
a 10Base-T network interface card, construct a 10Base-T crossover
cable and connect the wires as shown in Figure 4.

3.3 CONNECTING 10BASE-T ETHERNET PORT TO HUB (DCE)
The 10Base-T interface is configured as DTE (Data Terminal Equipment), just like a 10Base-T network interface card in a PC. Therefore, it
“expects” to connect to a 10Base-T Hub using a straight-through RJ-45
8
cable. Figure 5 shows how to construct a cable to connect the 10Base-T
interface to a 10Base-T Hub.

3.4 CONNECTING POWER
An external AC or DC power supply is available separately. This connection is made via the barrel jack on the rear panel of the Model 2155. No
configuration is necessary for the power supply (See Appendix B on
page 16 for domestic and international power supply and cord options).
3.5 POWER INPUT CONNECTOR
The
2155 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).

easy reach of the operator’s position.
Caution
Connect the equipment to a 5 VDC source that is electrically isolated from the AC source. The 5 VDC source is to
be reliably connected to earth.

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 Model 2155 features six front-panel LEDs that monitor connections on
the DSL and 10Base-T links, signaling, error and test modes. Figure 7
shows the front panel location of each LED . T ab le 1 describes the LED
functions.

LED status monitor indications
LED Description
DSL Link (Active Green) Solid green (On) indicates that the end to
end DSL Framer Link is up , signifying that the link across
the DSL span is active. The DSL Link LED is Off when the
link is down.
Status Blinks yellow from one to elev en times to indicate system
status. Each pulse pattern is separated by a 2 second “off”
period. Greater pulse patterns have higher priority (buff er
saturation has greater priority than an empty MAC table).
Valid system statuses are:
1 pulse—system status is okay
•
•
2 pulses—no MAC entries in the MAC Address Table
•
3 pulses—Clear to Send (CTS) or Carrier Detect (DCD)
from base unit are not asserted
•
4 pulses—IM1/I buffer is saturated
•
5 pulses—WAN receive frame(s) too large
6 pulses—WAN receive frame(s) not octet aligned
•
•
7 pulses—WAN receive frame(s) aborted
8 pulses—Detected WAN receive frame(s) with CRC
•
•
9 pulses—Detected LAN receive frame(s) too large
10 pulses—Detected LAN receive frame(s) not octet
•
aligned
•
11 pulses—Detected LAN receive frame(s) with bad
CRC
10BT Link (Active green) Solid green indicates that the 10Base-T
Ethernet interface has detected a valid SQE heartbeat, signifying a valid 10Base-T connection
NS (Active red) Solid red indicates that the Digital Signal Proces-
sors (DSPs) are not linked
ER (Active red) Flashing red indicates CRC errors on DSL
(framer) side if DSL Link is active or if bit errors are received
during loop/BER test
ER flashes once, to indicate a CRC error (during normal
operation) or bit errors (during Remote Loopback 511/511E
tests)
TM (Active yello w) Solid y ellow indicates an Active T est Mode .
The unit may be placed in test mode by the local user or by
the remote user.

4.2 TEST MODES
The Model 2155 has a built-in proprietary loopback test mode, plus a
built-in V.52 BER test pattern generator, for evaluating the communication link. These tests can be activated from the front panel of the
Model 2155 Ethernet Extenders.
Remote Digital Loopback (RDL)/V.52 (BER)
The Remote Digital Loopback (RDL) test checks the communication link
between two Model 2155s.
Remote 2155Local 2155
RDL initiated
Figure 8.
Remote digital loop
To use the Remote Digital Loopback tests, do the following:
1. Locate the 511/RDL toggle switch on the front panel of the 2155 and
move it DOWN. This initiates the RDL and sends a 511 pattern into
the loop. If any errors are present, the local modem’s red “ER” LED
will blink.
2. If the above test indicates no errors are present, move the toggle
switch UP, activating the 511E/RDL test (with errors present). If the
test is working properly, the local modem’s red “ER” LED will blink
approximately once per second. A successful 511E/RDL test will
confirm that the link is in place, and that the Model 2155’s built-in
“511” error generator and detector are working properly.
