1.1 RADIO AND TV INTERFERENCE

The Model 1193RC 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 1193RC 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 interfer-

ence will not occur in a particular installation. If the Model 1193RC

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

2.2 DESCRIPTION

The Patton Electronics

Model 1193RC

extends E1

(G.703/G.704) service over Single-mode fiber. A pair of 1193RC

Single-Mode Fiber Modems provides G.703/G.704 network "extension"

between remote locations (See Figure 1 below).

The Model 1193RC is designed to transmit/receive G.703/G.704

data over one strand of fiber. The Model 1193RC allows transmission

over Single-mode fiber with distances up to 50km (31 miles). The

clocking options for the Model 1193RC include Internal, Network (from

G.703/G.704 Network), or Receive Recovered clock (from fiber line).

The Model 1193RC also incorporates V.54 compliant local/remote

loopbacks and V.52 compliant 511/511E test patterns. Front panel

switches activate test patterns and loopbacks. LED status indicators

monitor the fiber and G.703/G.704 links. The Model 1193RC is sup-

plied with a 1001RCM703FC (with an FC connector) or a

1001RCM703SC (with an SC fiber connector) rear card.

The Model 1193RC is equipped with eight DIP switches, which

allow configuration of the unit for a wide variety of applications. This

section describes location of the switches and explains all possible

configurations.

3.1 CONFIGURE THE HARDWARE DIP SWITCHES

The 8 external dip switches are accessible from the underside of

the Model 1193RC (See Figure 2 below).

Figure 3 shows the orientation of the DIP switches in the

“ON” and “OFF” positions.

3.1.1 Configure the Model 1193RC

Switches S1 through S8 may be used to configure clocking modes

and line coding. Default settings of the switches are shown in the table

below. A description of the switch options follows the table.

Switches S1 and S2: Clock Mode

Use switches S1 and S2 to determine clock mode of the 1193RC.

On Off Receive Recover Transmit clock derived from the Receive

data on the fiber side.

Off On Network Transmit clock derived from G.703/G.704

Off Off Internal use only

Switch S3 and S4: Line Coding Options

Use switches S3 and S4 to determine whether the G.703/G.704 line

coding is HDB3 or AMI (for older telecommunications equipment). The

line coding must be the same line coding prescribed by the NAP

(Network Access Provider). Most applications will use HDB3.

High Density Bipolar 3 (HDB3): In HDB3 coding, the transmitter

deliberately inserts a bipolar violation when excessive zeros in the

data stream are detected. The receiver recognizes these special vio-

lations and decodes them as zeros. This method enables the net-

work to meet minimum pulse density requirements. Use HDB3

unless AMI is required in your application.

Alternate Mark Inversion (AMI): AMI defines a pulse as a

“mark,” a binary one, as opposed to a zero. In an E1 Network con-

nection, signals are transmitted as a sequence of ones and zeros.

Ones are sent as pulses, and zeros are sent as spaces, i.e., no

pulse. Every other pulse is inverted from the previous pulse in

polarity, so that the signal can be effectively transmitted. This

means, however, that a long sequence of zeros in the data stream

will cause problems, since the modem receiving the signal relies

on the signal to recover the 2.048 Mbps clock.

If you must use AMI, ensure that the data terminal equipment con-

nected to the unit provides a minimally acceptable pulse density.

For this reason, there are advantages to using HDB3 instead. AMI

coding does not inherently account for ones density. To meet this

requirement, ensure that the data inherently meets pulse density

requirements.

3.2 Configure the Rear Interface Card

The Model 1193RC has two interface card options: the Model

1001RCM703SC (with SC fiber connector) and 1001RCM703FC (with

FC fiber connector). See Figure 4, at upper right. Each of these inter-

face cards support one fiber connector, two BNC and one RJ-48C line

connectors.

The interface card for the Model 1193RC is shipped configured for

use with a BNC connection to the G.703/G.704 Network. If your

Network connection is using BNC, skip this section.

NOTE: The 1193RC Series rear cards are specifically

designed to operate with the Model 1193RC function card and

must not be swapped with other Patton function cards.

Jumper Configuration

The rear interface card for the Model 1193RC has four internal

jumpers: JP2, JP3, JP4 and JP5. These jumpers are used to match

input/output impedance between the module and external line on the

G.703/G.704 Interface. The jumper settings select either a BNC (75-

ohm) or an RJ-48C (120-ohm) interface. Figure 5 below shows the top

view of the printed circuit board (PCB) and the location of the jumpers.

Figure 5: Top view of 1193RC circuit board and location of jumpers

Note: Electronic equipment is sensitive to ESD (electrostatic dis-

charge). When you change the internal jumpers on the

1001RCM703XX, use a grounding strap to avoid damages. For more

information call Patton Technical Support (301) 975-1007.

Powering Up Your 1001R14 Rack

The power supplies that come with your 1001R14 rack system are

equipped with a power entry connector on the rear card. The power

supplies are Hot-Swappable, so you are not required to remove the

cards from the rack while applying power to the system.

4.1.2 Installing Model 1193RC Series Into the Rack Chassis

The Model 1193RC 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 1193RC 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 chas-

sis.

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.

This section describes the functions of the Model 1001R14 rack

chassis, tells how to install front and rear Model 1193RC Series cards

into the chassis, and how to connect to the G.703/G.704 Network and

to fiber optic cable.

4.1 THE MODEL 1001R14 RACK CHASSIS

The Model 1001R14 Rack Chassis (Figure 6, below) has fourteen

short range modem 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 extract-

ed and transported conveniently.

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.

Figure 6: Model 1001R14 Rack Chassis with power supply

WARNING! There are no user-serviceable parts in the

power supply section of the Model 1193RC Series.

Voltage setting changes and fuse replacement should

only be performed by qualified service personnel.

1007 for more information.

4.3 CONNECTING THE FIBER INTERFACE

The Model 1193RC is designed to be connected to another Model

1193RC or 1193. The Model 1193RC supports communication

between G.703/G.704 equipment over Single-mode fiber at distances

up to 50 km (31 miles). One modem can connect to another on the

end of a single string of fiber optic cable.

To connect two Model 1193RCs, use one strand of 9/125 micron

Single-mode fiber. The fiber connects to each Model 1193RC using

either an FC or SC connector.

Figure 9 below shows a close-up of FC and SC connector types.

Figure 9. Single-mode fiber connectors (FC and SC)

WARNING: Model 1193RC uses a Laser Diode to transmit invisible light into the fiber.

Exposing eyes to this light can cause permanent damage. To prevent eye damage, DO NOT

DIRECT DISCONNECTED FIBER OR FIBER CONNECTOR OF THE MODEM IN THE

DIRECTION OF THE EYES.

4.2 CONNECTING TO THE G.703/G.704 NETWORK

There are two ways to connect to the G.703/G.704 Network. This

section describes both options. After selecting the appropriate connec-

tion, set the internal jumpers as described in section 3.2 of this manual.

4.2.1 Connecting theTwisted Pair (120 Ohm) to G.703/G.704 Network

The rear interface card for the Model 1193RC is equipped with a

single RJ-48C jack option for connections to a G.703/G.704 Network. If

your G.703/G.704 Network terminates via an RJ-48C, use the diagram

below (Figure 7).

4.2.2

Connecting the Coax Cable to the G.703/G.704 Network

The rear interface card for the Model 1193RC is also equipped with

dual female BNCs (TX and RX) for connection to a 75 ohm dual coax

G.703/G.704 Network interface. If your G.703/G.704 Network terminates

via dual coaxial cable, use the diagram below to make the proper con-

nections. The connector pinout and signals are shown in Figure 8,

below.

Once the Model 1193RC is properly configured and installed, it should

operate transparently. This sections describes power-up, LED status moni-

tors, and the built-in loopback test modes.

5.1 LED STATUS MONITORS

The Model 1193RC features six front panel status LEDs that indicate

the condition of the modem and communication link. Figure 10 below

shows the front panel location of each LED.

Functions of LEDs are as follows:

Fiber The green Fiber LED indicates reliable data on the fiber side.

E1 The green E1 LED indicates reliable data on the G.703/G.704

side.

LOS The red LOS indicates that syncronization between modems

has not been established. Blinking red LOS LED indicates the

presence of coding errors.

NS The red NS LED indicates that the signal on the fiber side is

too weak to be detected. That could be due to any of the following

reasons:

- break in the fiber optic cable

- length of the fiber optic cable exceeds the maximum distance

- problem with Fiber LED.

ER Flashing red ER LED indicates errors in 511 test pattern

TM The yellow TM LED indicates that the modem is in a test mode

(Local/Remote Loopback or 511/511E test pattern). Opaque LED

indicates normal operation.

5.2 POWER-UP

After both the local and remote Model 1193RCs are powered

up, a synchronization process will occur to establish a link. The synchro-

nization process should take approximately 5 seconds. Any time one of

the Model 1193RCs lose power (i.e., in a lightning storm), the local and

remote units will re-synchronize before they can resume data transmis-

sion.

When the local and remote Models 1193RC have established a link

and are passing reliable data, the following LED conditions will exsit:

· Fiber = GREEN

· E1 = GREEN

· LOS = OFF

· NS = OFF

· ER = OFF

· TM = OFF

5.2 TEST MODES

The following section describes the test patterns and loopbacks

used in the Model 1193RC. The Model 1193RC offers V.54 compliant

local/remote loopback tests, plus a built-in V.52 BER test pattern gener-

ator to evaluate the condition of the modems and the communication

link. These tests can be activated physically from the front panel.

5.2.1 Local Loopback

The local loopback test checks the operation of the local Model

1193RC, and is performed separately on each unit. The following sec-

tion describes how to perform a local loopback test between the

Network and a local connection.

Any data sent to the local Model 1193RC in this test mode will be

echoed (returned) to the user (see Figure 11 below). If two Model

1193RC units are linked when the LAL is activated, data sent from the

remote modem will also be looped back to the remote terminal equip-

ment.

To test the local connection, follow these steps:

1. Activate LAL by moving the front panel toggle switch RIGHT to

"Local". Once the Local Loopback is activated, the Model 1193RC trans-

Figure 11. Local loopback diagram

G.703/G.704

Network

Figure 10. Front Panel of 1193RC

mit output will be connected to its own receiver. The TM LED will light

up.

2. Perform a BER (Bit Error Rate) test on each unit using a separate

BER tester. If the BER test equipment indicates no faults but the data

indicates a fault, follow the manufacturer's checkout procedures for the

data terminal. Also check the interface cable between the terminal and

the Model 1193RC. The BER test can also be performed using a built-

in 511/511E pattern generator. (See section 5.2.3 on how to use the

built-in 511/511E pattern generator.)

3. Upon completion of the LAL test, return the front panel switch to

NORMAL position. The TM LED should turn off.

5.2.2. Remote Digital Loopback (RDL)

The Remote Digital Loopback test checks the performance of both

the local and remote Models 1193RC, and the communication link

between them. In this test, any characters sent from the originating

device to the remote unit will be returned (see figure 12). Any data

sent to the remote unit from the remote DTE wil be ignored.

To perform a RDL test, follow these steps:

1. Activate RDL by moving front panel toggle switch LEFT to

"Remote". The TM LED on both local and remote units will light up.

2. Perform a BER (Bit Error Rate) test on the system, using BER tester

on the local end. BER test can also be performed using built-in

511/511E pattern generator. (See section 5.2.3 on how to use the built-

in 511/511E pattern generator.)

3. If the BER test equipment indicates a fault and the Local Analog

Loopback test was successful for both Model 1193RCs, there may be

a problem with the line between the units.

4. Upon completion of the RDL test, return the front panel switch to

NORMAL position. The TM LED should turn off on both local and

remote units.

5.2.3. The V.52 Test Pattern Generator

To use the V.52 BER test in conjunction with the Local or Remote

Loopbacks, follow these instructions:

1. Locate the "511/511E" toggle switch on the front panel of the Model

1193RC and move it RIGHT. This activates the V.52 BER test mode

and transmits a "511" test pattern into the loop. If any errors are pres-

ent, the local modem's red "ER" LED will blink intermittently.

2. If the above test indicates no errors, move the V.52 toggle switch

LEFT, activating the "511/E" test with errors present. If the test is work-

ing properly, the local modem's red "ER" LED will blink approximately

once every 2 seconds. A succesful "511/E" test will confirm that the

link is in place, and that the Model 1193RC’s built-in "511" generator

and detector are working properly.

Figure 12. Remote loopback diagram.

G.703/G.704

Network

Note: When set for Network Clock Mode, the unit will derive its timing

from the G.703/G.704 interface. It expects its clock will come from the

G.703/G.704 interface. Failure to connect to the G.703/G.704 may

result in bit errors during a 511 or 511/E test.
