2.2 DESCRIPTION

The Patton Model 1092RC

KiloModem 2W

baseband modem allows synchronous or asynchronous data to be transmitted up to 5 miles (8 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 1092RC is perfect for LAN interconnection or high speed internet links.

Supporting 2B1Q encoding, Automatic Equalization and Auto Gain Control, the Model 1092RC compensates for poor line quality. Swappable interface driver boards and interface cards allow the user to easily change applications between RS-232 and V.35. Future driver boards and interface cards will include X.21, G.703, and RS-530. The Model 1092RC also features convenient front panel diagnostic switches and LEDs that allow for easy setup, configuration and testing.

The Model 1092RC is designed to fit into Patton’s 2U (3.5”) high rack chassis

. This 16-card chassis has a switchable 120/240 VAC

power supply (optional 48 VDC) and mounts cards in a mid-plane architecture: The front card can be plugged into different rear cards.

The power switch is located on the front panel. When plugged in and switched on, a red front panel LED will glow. Since the Model 1000R16 is a "hot swappable" rack,

it is not necessary for any cards to

be installed before switching on the power supply

. The power supply

may be switched off at any time without harming the installed cards.

NOTE: Please refer to the Model 1000RP Series User Manual

and DC Rack Mount Power Supplie

s for fuse and power card

replacement information.

4.2 INSTALLING THE MODEL 1092RC SERIES INTO THE CHASSIS

The Model 1092RC 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 1092RC 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

gently

into the card-edge receptacle of the

rear card. It should “click” into place.

5. Secure the front card using the thumb screws.

4.3 WIRING THE MODEL 1092RC SERIES

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

4.3.1 Connection to a “DTE” Device

Regardless of the interface module you choose, the Model 1092RC’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 C as a guide.

4.3.2 Connection to a “DCE” Device

Since the Model 1092RC’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 C as a guide.

4.3.3 Connection to the Twisted Pair Interface

The Model 1092RC 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 1092RC:

1. These units work in

pairs

. Therefore, you must have one Model 1092RC (or a compatible model) at each end of a single twisted pair interface.

2. To function properly, the Model 1092RC needs one 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

Notice! Any terminal cable connected to the Model

1092RC must be shielded cable, and the outer shield must be 360 degree bonded–at both ends–to a metal or metalized backshell.

4.3.4 Two-Wire Cable Connection Via RJ-45

1. The RJ-45 connector on the Model 1092RC’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.

2. Proper wiring of pairs between the two modems is as follows:

PIN# PIN# SIGNAL

TIP 4--------------------------------------------- 4 TIP RING 5--------------------------------------------- 5 RING

4.3.5 Connection to the Control Port Interface

Please refer to the Model 1000CC Control Card user manual for

cable requirements of the Control Port Interface.

Notice! Any modular twisted pair cable connected to

the Model 1092RC must be shielded cable, and the outer shield must be properly terminated to a shielded modular plug on both ends of the cable.

5.0 OPERATION

Once the Model 1092RC 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 1092RC features twelve front panel LEDs that monitor power, the DTE signals, network connection and test modes. Figure 10 (below) shows the front panel location of each LED. Following Figure 10 is a description of each LEDs function.

TD & RD glow red 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 red, 1 green. CTS glows

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

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

red 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.

511

511ER

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 red to indicate that the Model 1092RC

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

5.2 TEST MODES

The Model 1092RC 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 Using Local Line Loopback (LLB)

The Local Line Loopback (LLB) test checks the operation of the local Model 1092RC, and is performed separately on each unit. Any data sent to the local Model 1092RC in this test mode will be echoed (returned) back to the user device (see Figure 11, 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 two ways: First, by moving the front panel toggle switch to the right to “Local”. Second, by raising the LLB signal on the interface (see Appendix C). Once LLB is activated, the Model 1092RC transmitter output is connected to its own receiver. The “TM” LED should be lit.

Figure 11 Local Line Loopback

1092RC

1090

NOTE: Switch S1-8 must be in the “ON” position).

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 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 1092RC.

5.2.2 Using Remote Digital Loopback (RDL)

The Remote Digital Loopback (RDL) test checks the performance of both the local and remote Model 1092RCs, and the communication link between them. Any characters sent to the remote Model 1092RC in this test mode will be returned back to the originating device (see Figure 12, 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 1092RC and looped back.

To perform an RDL test, follow these steps:

1. Activate RDL. This may be done in two ways: first, by moving the front panel toggle switch to the Left to “Remote”. Second, by raising the RDL signal on the interface (see Appendix C). NOTE: Switch S1-8 must be in the “ON” position.

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 1092RCs, 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 Using the 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 1092RC 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 glow. A successful “511/E” test will confirm that the link is in place, and that the Model 1092RC’s built-in “511” generator and detector are working properly.

*NOTE: The above V.52 BER tests can be used independently of the Remote Digital Loopback tests. This requires two operators: one to initiate and monitor the tests at the local Model 1092RC, and one to do the same at the remote Model 1092RC. In this case, the test pattern sent by each Model 1092RC will not be looped back, but will be transmitted down the line to the other Model 1092RC.
