2.2 DESCRIPTION  
The Patton Model 1092ARC KiloModem 2W/4WTM baseband  
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.

Switches S1-4: Management Setting  
When setting the SNMP Management, the DTE rate switches (S1-  
1, 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.  
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.  
Use Switch S1-4 to configure the 1092ARC’s management setting.

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 (SNMP management mode).

Control Port Management  
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

4.1 THE MODEL 1001R14 RACK CHASSIS  
Position 2&3 = SGND (Pin 8) and FRGND directly connected  
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  
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 (301)975-1007  
for more information.

4.2 INSTALL THE MODEL 1092ARC SERIES INTO THE CHASSIS  
4.3.2 Connect to a “DCE” Device  
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 B as a guide.  
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.  
4.3.3 Connect the Twisted Pair Interface  
2. Secure the rear card using the metal screws provided.  
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:  
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.  
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.  
4. Push the front card gently into the card-edge receptacle of the  
rear card. It should “click” into place.  
5. Secure the front card using the thumb screws.  
2. To function properly, the Model 1092ARC needs one or two  
twisted pair 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 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.  
.
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 through cable 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 B as a guide.

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.

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.  
glows yellow to indicate that the Model 1092ARC

placed in test mode by the local user or by the  
remote user.  
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.  
NS  
(No Signal) glows red to indicate that the local  
Model 1092ARC has not yet connected with the  
remote Model 1092ARC.  
2. Verify that the data terminal equipment is operating properly  
and can be used for a test.  
5.2 TEST MODES  
3. Perform a V.52 BER (bit error rate) test as described in  
Section 5.2.3. 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.  
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)  
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.  
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.
