product should it fail within one year from the first date of shipment.

This warranty is limited to defects in workmanship or materials, and
does not cover customer damage, abuse or unauthorized modification.
If this product fails or does not perform as warranted, your sole
recourse shall be repair or replacement as described above. Under no
condition shallPatton Electronicsbe liable for any damages incurred
by the use of this product. These damages include, but are not limited
to, the following: lost profits, lost savings and incidental or
consequential damages arising from the use of or inability to use this
product. Patton Electronicsspecifically disclaims all other warranties,
expressed or implied, and the installation or use of this product shall be
deemed an acceptance of these terms by the user.

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.

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 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.

3.0 CONFIGURATION

This section describes the hardware and software configuration
switches and jumpers, and provides detailed instructions for all possible
settings. Refer to the Model 1001MC SNMP Management Card User
Manual for SNMP options.

3.1 Configure the Hardware Switches

The Model 1092ARC Series front card defaults

to the use of
hardware switches for configuration. The Model 1092ARC has an
interface driver board, two eight-position DIP Switches, and one 4­position DIP Switch on the front card (see Figure 1, below).
Figure 2 shows the orientation of the DIP switches with respect to the
“ON” and “OFF” positions.

2.3 1092A SNMP MANAGEMENT SOLUTIONS

Model 1092A is SNMP manageablewhen it is connected to a
rack-mounted Model 1092ARC . SNMP management is enabled
through a 1001MC rack management card located in the Patton
Electronics Rack System.

2.3.1 HTTP/HTML Management

The 1001MC maintains HTML pages that can be viewed through a
web browser. You can display remote statistics and configure Model
1092A parameters simply by entering the 1001MC’s IP address into the

3.1.2 Configuration Switch Set “S1”

The configuration switches on S1 allow you to specify the data
rate, async/sync data format, transmit clock source and response to
RDL request. Default settings of S1 are shown in the table below.

Switches S1-1 and S1-2: Data Rate

Use Switches S1-1 and S1-2 with Switch S5-1to determine the
operable Sync or Async bit rate for Model 1092ARC. The settings
shown below are the only applicable bit rate settings.

3.1.1 Reversible Interface Driver Board

The Model 1092ARC Series features switchable interface driver
boards that allow a wide range of DTE interface connections. Figure 3
shows the Interface Driver Board on the top of the 1092ARC PC board.

Follow the instructions below to select the correct interface for your

application:

1. With the 1092ARC pulled out of the rack or clusterbox chassis,
locate the driver board on the top of the 1092ARC front card.

2. Lift the interface board gently off of the PC board.

3. Locate the correct interface on the bottom of the driver board.
For example, the RS-232/V.35 interface board is marked

“THIS SIDE UP FOR RS-232”on one sideand “THIS SIDE
UP FOR V.35”on the other side.

4. Re-orient the interface board into the socket with the
appropriate interface pointed UP and with the arrow pointing
toward the front panel of the Model 1092ARC PC board.

5. Push the Interface Driver Board gently onto the socket and re­install into the rack or cluster system.

Switch S1-8: Response to Remote LoopRequest

Use Switch S1-8 to allow the Model 1092ARC to enter the Remote
Digital Loopback diagnostic test when requested to do so by the far end
modem. For example, when Switch S1-8 is set to “ON”, it will enter
RDL mode (See Section 5.2.2) when requested to do so by the remote
modem.

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.

Switch S1-3: Data Set Ready During Local Line Loopback Test

Use Switch S1-3 to control the behavior of the DSR signal at the

EIA interface during the local line loopback test.

S1-3

Setting Description

On Enabled DSR is on during local

line loop (default)

Off Disabled DSR is off during local

Switches S1-4: Management Setting

When setting the SNMP Management, the DTE rate switches (S1­1, S1-2, and S2-1) are also needed to be at the ON position. Therefore,
to set a 1092A unit SNMP management mode, the following switches
have to be at the ON position, S1-1, S1-2, S2-1, and S1-4.

Use Switch S1-4 to configure the 1092ARC’s management setting.
