1.1RADIO AND TV INTERFERENCE

The Model 1092ARC 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 1092ARC has been tested and found
to comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J 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
1092ARC 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). In the event the user
detects intermittent or continuous product malfunction due to nearby
high power transmitting radio frequency equipment, the user is strongly
advised to take the following steps: use only data cables with an
external outer shield bonded to a metal or metalized connector; and,
configure the rear card as shown in section 3.3 of this manual.

2.2 DESCRIPTION

The Patton Model 1092ARC KiloModem 2W/4WTMbaseband

modem allows synchronous or asynchronous data to be transmitted up
to 11 miles (17.6 km) over one or two twisted pair (2 or 4 Wire).
Supporting synchronous speeds up to 128 kbps and asynchronous
speeds up to 38.4 kbps, the 1092ARC is perfect for LAN
interconnection or high speed internet links.

To compensate for poor line quality, the Model 1092ARC
supports 2B1Q encoding, Automatic Equalization, and Auto Gain
Control. The 1092ARC is fully SNMP manageable using Patton’s Model
1001MC Management Card. Software configuration is performed via
the VT100 screens. Swappable interface driver boards and interface
cards allow the user to easily change applications between RS-232,
V.35, X.21, G.703, RS-530, 10Base-T, or Ethernet. The Model
1092ARC also features convenient front panel diagnostic switches and
LEDs that allow for easy setup, configuration and testing.

The Model 1092ARC is designed to fit into Patton’s 1001 2U
(3.5”) high rack chassis. This chassis uses a mid-plane architecture
allowing front cards to be plugged into different rear cards. Please see
the Model 1001RP14 manual for more information on the power supply
options.

3.1.3 Configuration Switch Set “S2” - Management Port Address

If the address is 0 (all ON positions ON S2), then the unit will run
completely from its' dip-switch configuration. This can be useful for
testing circuits independently of the management system.

In order to use the SNMP or control port management, an address
is required. If an address is placed on the switch, the unit will boot from
its stored flash configuration. It begins looking for POLL commands
from the Model 1001MC (SNMPmanagement mode).

Switch S2 allows an 7 bit address to be assigned to a link. The
following rules apply to setting the address. Bit S2-1 is the least
significant bit. A bit set to "ON" is considered a "0". A bit set to "OFF" is
considered a "1". Patton Electronics suggests that you set your
addresses starting with address 1 at the far left of your rack (farthest
away from the power supplies) and increment the numbers by one as
you go from left to right. Setting the addresses in this manner will make
configuration easier as you start using the web page management. An

example of this is shown in table A-1.

This section describes the functions of the Model 1001R14 rack
chassis, tells how to install front and rear Model 1092ARC Series cards
into the chassis, and how to connect to the twisted pair interface and
the serial interface.

4.1 THE MODEL 1001R14 RACK CHASSIS

The Model 1001R14 Rack Chassis (Figure 9, below) has 16 card
slots, plus its own power supply. Measuring only 3.5” high, the Model
1001R14 is designed to occupy only 2U in a 19” rack. Sturdy front
handles allow the Model 1001R14 to be extracted and transported
conveniently.

Figure 9: Model 1001R14 Rack Chassis with power supply

25

4.1.1 The Rack Power Supply

The power supply included in the Model 1001R14 rack uses the
same mid-plane architecture as the modem cards. The front card of
the power supply slides in from the front, and the rear card slides in
from the rear. They plug into one another in the middle of the rack.
The front card is then secured by thumb screws and the rear card by
conventional metal screws.

WARNING!There are no user-serviceable parts in the

power supply section of the Model 1092RC Series.Voltage
setting changes and fuse replacement should only be
performed by qualified service personnel. Contact Patton
Electronics’ Technical support at

for more information.

4.2 INSTALL THE MODEL 1092ARC SERIES INTO THE CHASSIS

4.3.2 Connect to a “DCE” Device

The Model 1092ARC Series is comprised of a front card and a rear
card. The two cards meet inside the rack chassis and plug into each
other by way of mating 50 pin card edge connectors. Use the following
steps as a guideline for installing each Model 1092ARC Series into the
rack chassis:

1. Slide the rear card into the back of the chassis along the metal
rails provided.

2. Secure the rear card using the metal screws provided.

3. Slide the front card into the front of the chassis. It should
meet the rear card when it’s almost all the way into the
chassis.

4. Push the front card gentlyinto the card-edge receptacle of the
rear card. It should “click” into place.

5. Secure the front card using the thumb screws.

4.3 WIRE THE MODEL 1092ARC SERIES

Each of the rear interface cards compatible with the Model
1092ARC Series has one terminal interface port and one 2-wire/4-wire
(twisted pair) port. For specific interface pin-outs, refer to the diagrams
in the Appendix of this manual.

.

Since the Model 1092ARC’s serial port is always wired as a DCE,
you must use a null modem cable when connecting to another DCE
device such as a CSU/DSU, modem or multiplexer. This cable should
be of the shortest possible length that is appropriate to the interface you
are using. When purchasing or constructing a null modem interface
cable, use the pin diagrams in Appendix Bas a guide.

4.3.3 Connect the Twisted Pair Interface

The Model 1092ARC supports communication between two DTE
devices at distances to 5 miles (8 km) over 24AWG (.5mm) twisted pair
wire. There are two essential requirements for installing the Model
1092ARC:

1. These units work in pairs. Both units at the end of the twisted
pair must have the same two-wire/four-wire setting. For
instance, if you are operating in two-wire mode, both units
must be in the two-wire setting. Similarly, if you are operating
in four-wire mode, both units must be in the four-wire setting.

2. To function properly, the Model 1092ARC needs one or two
twistedpair of metallic wire. This twisted pair must be
unconditioned, dry, metallic wire, between 19 (.9mm) and 26
AWG (.4mm) (the higher number gauges may limit distance
somewhat). Standard dial-up telephone circuits, or leased
circuits that run through signal equalization equipment, or
standard, flat modular telephone type cable, are not
acceptable.

4.3.1 Connect to a “DTE” Device

Regardless of the interface module you choose, the Model
1092ARC’s serial port is always wired as a DCE. Therefore it “wants”
to plug into a DTE such as a terminal, PC or host. When making the
connection to your DTE device, use a straight throughcable of the
shortest possible length that is appropriate to the interface you are
using. When purchasing or constructing an interface cable, please
refer to the pin diagrams in Appendix Bas a guide.

28

The RJ-45 connector on the Model 1092ARC’s twisted pair interface
is polarity insensitive and is wired for a two-wire interface. The
signal/pin relationships are shown in Figure 9 below.

5.0 OPERATION

Once the Model 1092ARC is properly configured and installed, it
should operate transparently. This sections describes functions of the
LED status indicators, and the use of the built-in loopback test modes.

5.1 LED STATUS INDICATORS

The Model 1092ARC features twelve front panel LEDs that monitor
power, the DTE signals, network connection and test modes. Figure
11(below) shows the front panel location of each LED. Following Figure
11 is a description of each LED function.

cable requirements of the Control Port Interface.

Model 1092ARC

Figure 11.The Model 1092ARC Series' front panel LEDs

Note: LEDs described as yellow are red in earlier
versions of the 1092ARC.

TD & RD glow yellow to indicate an idle condition of Binary

“1” data on the respective terminal interface
signals. Green indicates Binary “0” data.

CTS consists of 2 LEDs, 1 yellow, 1 green. CTS glows

green to indicate that the Clear to Send signal from
the modem is active. Yellow indicates inactive
CTS.

CD consists of 2 LEDs, 1 yellow, 1 green. CD glows

yellow if no carrier signal is being received from the
remote modem. Green indicates that the remote
modem’s carrier is being received.

DTR glows green to indicate that the Data Terminal

Ready signal from the terminal is active.

29

30

ER glows red to indicate the likelihood of a Bit Error

in the received signal. During the 511 or 511/E
test, ER flashes to indicate that the Test Pattern
Detector has detected a bit error.

TM glows yellow to indicate that the Model 1092ARC

has been placed in Test Mode. The unit can be
placed in test mode by the local user or by the
remote user.

NS (No Signal) glows red to indicate that the local

Model 1092ARC has not yet connected with the
remote Model 1092ARC.

5.2 TEST MODES

The Model 1092ARC offers two proprietary loopback test modes,
plus a built-in V.52 BER test pattern generator, to evaluate the condition
of the modems and the communication link. These tests can be
activated physically from the front panel, or via the interface.

5.2.1 Local Line Loopback (LLB)

The Local Line Loopback (LLB) test checks the operation of the
local Model 1092ARC, and is performed separately on each unit. Any
data sent to the local Model 1092ARC in this test mode will be echoed
(returned) back to the user device (see Figure 12, below). For
example, characters typed on the keyboard of a terminal will appear on
the terminal screen.

To perform an LLB test, follow these steps:

1. Activate LLB. This may be done in one of three ways:

- Move the front panel toggle switch to the right to
“Local”.

- Raise the LLB signal on the interface (see Appendix B).

- Set Local Loop from the VT100 screen.

Once LLB is activated, the Model 1092ARC transmitter output is
connected to its own receiver. Data is also looped back to the line. The
“TM” LED should be lit.

2. Verify that the data terminal equipment is operating properly
and can be used for a test.

3. Perform a V.52 BER(bit error rate) test as described in
Section5.2.3. If the BER test equipment indicates no faults,
but the data terminal indicates a fault, follow the
manufacturer’s checkout procedures for the data terminal.
Also, check the interface cable between the terminal and the
Model 1092ARC.

5.2.2 Remote Digital Loopback (RDL)

The Remote Digital Loopback (RDL) test checks the performance
of both the local and remote Model 1092ARCs, and the communication
link between them. Any characters sent to the remote Model 1092ARC
in this test mode will be returned back to the originating device (see
Figure 13, below). For example, characters typed on the keyboard of
the local terminal will appear on the local terminal screen after having
been passed to the remote Model 1092ARC and looped back.

Important!Do notsend a 511 test pattern from the test
equipment when you connect external test equipment to the
1092ARC .

To perform an RDL test, follow these steps:

32

1. Activate RDL. This may be done in three ways:

APPENDIX A

- Move the front panel toggle switch to the Left to “Remote”.

- Raise the RDL signal on the interface (see Appendix C).

- Set Remote Loopback from the VT100 screen.

Note: Remote Loopback cannot be activated until
approximately 45 seconds after the two modems have
linked to each other.

2. Perform a V.52 BER test as described in Section 5.2.3. If the
BER test equipment indicates a fault, and the Local Line
Loopback test was successful for both Model 1092ARCs, you
may have a problem with the twisted pair line between the
modems. You should then check the twisted pair line for
proper connections and continuity.

5.2.3 V.52 (BER) Test Pattern Generator

To use the V.52 BER tests in conjunction with the Remote Digital
Loopback tests* (or with Local Line Loopback tests), follow these
instructions:

1. Locate the “511/511E” toggle switch on the front panel of the
1092ARC and move it to the left. This activates the V.52 BER
test mode and transmits a “511” test pattern into the loop. If
any errors are present, the local modem’s red “ER” LED will
blink sporadically.

2. If the above test indicates no errors are present, move the
V.52 toggle switch to the right, activating the “511/E” 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 “511/E” test will confirm that the link is
in place, and that the Model 1092ARC’s built-in “511”
generator and detector are working properly.
