This section describes the location and orientation of the Model
1094ARC’s configuration switches and jumpers, and provides detailed
instructions for all possible settings.
3.1 CONFIGURING THE HARDWARE SWITCHES
The Model 1094ARC Series front card uses hardware switches for
configuration. There is an interface driver board strap, and three eightposition DIP switches, on the bottom side of the front card (see Figure
1, below).
Figure 2 shows the orientation of the DIP switches with respect to
the “ON” and “OFF” positions.
3.1.1 Reversible Interface Driver Board
The Model 1094ARC 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 1094ARC PC
board.
Follow the instructions below to select the correct interface for your
application:
1. With the 1094ARC front card pulled out of the rack or clusterbox chassis, locate the driver board on the top of the
1094ARC 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 side and “THIS SIDE
UP FOR V.35” on the other side . Other “single” interface
boards are marked with “FRONT” on one side of the board.
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 1094ARC PC board.
5. Push the Interface Driver Board gently onto the socket and reinstall into the rack or cluster system.

3.1.2 Connecting to a “DTE” Device
The serial port on most interface modules (all except the X.21
module) is hard-wired as a DCE. Therefore these modules “want” 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—we recommend 6 feet or less. When purchasing or constructing an interface cable, please refer to the pin diagrams in Appendix C as a guide.
3.1.3 Connecting to a “DCE” Device
If the Model 1094ARC interface module is hard-wired as a DCE
(all except the X.21 module), you must use a
null modem
cable when
connecting to a modem, multiplexer or other DCE device. This cable
should be of the shortest possible length—we recommend 6 feet or
less. When purchasing or constructing a null modem interface cable,
use the pin diagrams in Appendix C as a guide.
3.1.4 Configuring the X.21 Interface Module IM2RC/D
The serial port on the X.21 Interface Module is default wired as a
DCE, but may be switched to a DTE. This is done by reversing the orientation of the DCE/DTE strap, as described below:
To reverse DCE/DTE orientation, remove the interface module
according to the instructions in Section 3.1.1. The DCE/DTE strap is
located on the top side of the interface module’s PC board. The
arrows on the top of the strap indicate the configuration of the X.21
port (for example, if the DCE arrows are pointing toward the rear card
connector, the X.21 port is wired as a DCE). Reverse the DCE/DTE
orientation by pulling the strap out of its socket, rotating it 180º, then
plugging the strap back into the socket. You will see that the
DCE/DTE arrows now point in the opposite directions, showing the
new configuration of the X.21 port. Reinstall the module according to
the instructions in Section 3.1.1.
3.1.5 Configuration DIP Switch Set “S1” - Management Address
Switch S1 is used to set the address of the card in the NetLink
Network Management System. When the 1094ARC is installed with a
Model 1001MC, the cards and their remote units can be SNMP managed using a standard Network Management Station (NMS) or a standard web browser (i.e. Netscape, Internet Explorer, etc.). For more
information on setting the address, please see Appendix A of the
Model 1001MC Operations Manual.
NOTE: If you are not using your Model 1094ARC in an SNMP
managed environment, S1 switches should all be set to the ON
position.
3.1.6 Configuration DIP Switch Set “S2”
The configuration switches on S2 allow you to specify the Line
Rate, Clocking Mode and response to DTE Loop Enable. Default settings of S2 are shown in the table below.
Switches S2-1, S2-2, S2-3, S2-4, S2-5: Reserved for Future Use

This section describes the functions of the Model 1001R14 rack
chassis, tells how to install front and rear Model 1094ARC 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 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 extracted 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 9: Model 1001R14 Rack Chassis with power supply
WARNING! There are no user-serviceable parts in the
power supply section of the Model 1094ARC 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.
19
20
Powering the 1001R14 Rack
The power supplies that are shipped with your 1001R14 rack system are equipped with a power entry connector on the rear cards. The
power supplies are Hot-Swappable, so you are not required to remove
the cards from the rack when applying power to the system. Patton
Electronics recommends that if you wish to power OFF the rack, that
you remove the front card instead of removing the power cable from
the back of the rack. Keeping the power cable connected allows the
rack to remain grounded.
4.2 INSTALLING MODEL 1094ARC SERIES INTO THE CHASSIS
The Model 1094ARC 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 1094ARC 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 1094ARC SERIES
Each of the rear interface cards compatible with the Model
1094ARC 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 and E of this manual.
.
4.3.1 Connection to the Twisted Pair Interface
The Model 1094ARC 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
1094ARC:
1. These units work in
pairs
. Therefore, you must have one
Model 1094ARC (or a compatible model) at each end of a single twisted pair interface.
2. To function properly, the Model 1094ARC needs one twisted
pair of metallic wire. This twisted pair must be
uncondi-
tioned
, dry, metallic wire, between 19 (.9mm) and 26 AWG
(.4mm) (the higher number gauges may limit distance some
what). Standard dial-up telephone circuits, or leased circuits
that run through signal equalization equipment, or standard,
flat modular telephone type cable, are
not acceptable
.
4.3.2 Two-Wire Cable Connection Via RJ-45
1. The RJ-45 connector on the Model 1094ARC’s twisted pair
interface is polarity insensitive and is wired for a two-wire
interface.The signal/pin relationships are shown in Figure 10
below.
NOTE: Please refer to the Model 1001RP14 Series User
Manual
AC and DC Rack Mount Power Supplie
s for fuse and
power card replacement information.

IMPORTANT!: The Model 1094ARC has been optimized for
performance at high bitrates (DTE rates greater than 512 kbps).
To ensure accurate performance at these bit rates, please use
twisted pair line interface cable that is at least 330ft (100m) in
length.
21
22
4.3.3 Two-Wire Cable Connection Via Terminal Block
The two pin terminal block connector on the Model 1094ARC’s twisted
pair interface (TB rear card option) is polarity sensitive. Connection to the terminal block is made by connecting your two-wire cable to the connector supplied with your unit. For replacement parts please see Appendix B.

Once the Model 1094ARC is properly configured and installed, it
should operate transparently. These 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 1094ARC 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 10 is a description of each LEDs function.
TD & RD glows yellow to indicate an idle condition of Binary

5.2 TEST MODES
The Model 1094ARC 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 Overview
Figure 12 below shows the major elements used in the loop-back
and pattern tests available in the Model 1094ARC. Each block has
several functions. Following Figure 12 are descriptions that show how
the elements are used during Test Modes.
Figure 12: Block Diagram Model 1094ARC
Framer The framer is used to determine the status of
the line. In normal operation the framer transmits
and expects to receive framed packets from the
far end. If the framer receives framed packets
from the far end, CTS and CD will be active. If
framed packets are not received, CTS and CD
will be inactive. The restart procedure uses this
information to determine if a valid connection is
made (cable disconnect, poor cable quality, etc).
In normal Data Mode, if the box receives 4 seconds of unframed packets it will restart the box
and begin trying to re-establish a connection
with the far end. The distinction between framed
packets and unframed packets becomes important when we discuss the Pattern Generator.
Pattern Gen/Det This part of the Processor generates and
detects the 511/511E patterns. When transmitting 511 patterns, the information is unframed
(because it originates after the framer) and is
intended to be evaluated only by another
Processor. If the units are in Data Mode and the
pattern generator is enabled on one end of the
link, the far end will begin receiving unframed
packets and assume that the line has gone
down. During test modes, we force the pattern
generator to time out before it can cause the link
to be killed.
Loop Control This part of the Processor is used to control
loop-backs. In a Local Loop, the data is looped
back towards the local DTE. In a Remote Loop,
the data is looped back to the line, but it is also
allowed to pass through to the framer and to the
remote DTE.

Restart Procedure The restart procedure is in place to allow the
and Time Outs units to re-establish a connection after the
framer begins seeing unframed packets. The
Test Model Timing Chart below shows the
amount of time the framer must see consecutive
unframed packets before the unit will restart and
try to establish a new line connection. The reason that there are different Restart Times will
become apparent after reading the rest of the
document. The 511/511E Time Out shown refers
to the amount of time the 511/511E pattern will
be valid. At the end of this time the pattern will
automatically turn itself off and the normal data
path will be re-established. The ER led will flash
indicating to the user that the test has timed out.
The ER led will stop flashing once the 511/511E
switch is placed into the normal position.
Symbol Indicators
This symbol designates the origination or the
termination of a data path. The direction of the
arrow connected distinguish the two data paths.
This symbol designates an invalid data path. If
there is data present it should be ignored.
5.2.2 Loops and Patterns
The following section describes the Test Modes used in the Model
1094ARC. At the bottom of each Test Mode, a figure is included to
show the data path.
Local Loop There are two different modes of operation for a
Local Loop depending on the status of the units
at the time that the Local Loop is initiated. If the
units are not linked (NS LED on) and the Local
Loop is initiated, either by the front panel switch
or the DTE interface, the unit will enter mode 1.
If the units are linked, NS LED off, then the unit
will enter a mode 2 Local Loop.
A Mode 1 Local Loop is shown in Figure 13.
When the Local Loop is initiated, either by the
front panel switch or the DTE interface, the loop
will be activated within the local DSP. The data
present at the local DTE interface will be looped
back to the local DTE by the Loop Control block
within the Processor. Any data present on the
line or at the far end DTE interface is invalid.
The remote unit will remain in the StartUP
mode, NS LED off, CTS LED yellow, and CD
LED yellow, until the local unit is taken out of the
LocalLoop mode. After the Local Loop is deselected, the units will both be in StartUP mode
and the link will be established.
A mode 2 Local Loop is shown in Figure 14.
When the Local Loop is initiated, either by the
front panel switch or the DTE interface, two separate loop paths will be started. In the first path,
data presented to the local DTE interface will be
looped back to the local DTE within the framer.
In the second path data presented at the far end
DTE will be transmitted to the local DTE then
looped back within the local DTE Loop Control
block with the Processor. After the Local Loop is
deselected, the units will be placed back into
DataMode and the normal data paths will be reestablished.

Figure 14. Block Diagram Local Loop Mode 2
Local Loop When the unit is placed into a Mode 1 Local
with 511/511E Loop and the 511/511E pattern generator is acti-
vated, the local pattern generator begins sending out a 511/511E pattern to the Loop Control
block. The Loop Control block will loop this data
back to the 511/511E pattern detector block,
which will evaluate the data for errors. Because
the 511/511E pattern generator is contained
within the Processor the data is unframed so the
framer will begin seeing unframed packets. The
framer receives this unframed data and can not
distinguish this information from a line disconnection (this would cause the units' Restart procedure to start). What we have done to allow
this mode to work is to add time outs for the pattern generators. When the 511/511E is initiated
the line restart procedure is changed to one
minute. The 511/511E pattern will timeout after
45 seconds. So if the 511/511E is turned on during a local loop, the restart procedure is set to
one minute, but the 511/511E pattern will timeout after 45 seconds, allowing the framer to
begin seeing framed packets (and not restart the
box). After the 511/511E pattern times out, the
ER led will begin flashing.
Local Loop It will remain this way until the pattern generator
with 511/511E switch is turned off. Note that the data at the
(continued) local DTE and the remote DTE are not valid.
Because the data is unframed there is no way
for the framer to send this data out to the DTE.
This is an important distinction because other
Patton units will send out the 511 pattern.
When the unit is placed into a Mode 2 Local
Loop, the 511/511E pattern generator on the
local unit is unavailable for transmission. As can
be seen from Figure 14, the 511/511E pattern
generator has no data path connections available. The 511/511E pattern generator is still
available on the remote unit. For more information on the proper operation of this pattern generator please refer to the "Remote Digital Loop
with 511/511E" section.

Remote Digital The Remote Loop uses the EOC channel (an
Loop out-of-band signaling channel) to establish the
remote link. Upon the RDL switch being thrown
or DTE initiation, a RDL_ON Request signal is
sent to the remote unit. The Remote unit then
responds with an RDL Acknowledge command
and the link is established. Data originates at the
local DTE and is looped at the Remote DSP
back to the Local DTE. Note that the data is also
passed through to the Remote DTE and is not
squelched. When a Remote unit enters RDL, it
changes its' Restart timeout to one minute (the
reason will be explained in the RDL with
511/511E section). If the line is disconnected,
the local unit will Restart (NS led activated) after
4 - 6 seconds, but the Remote unit will wait for
one minute before it Restarts. Note that the
transmit data at the Remote DTE is ignored.
When the switch is thrown or the DTE removes
the RDL request, the local unit will transmit an
RDL_OFF Request to the Remote unit. The
local unit will keep its' TM led active until this
request has been completely sent out. If the
switch is thrown again before the completion of
the termination phase the switch will be ignored
until it is placed back into the normal position.
Figure 17. Block Diagram Remote Loop
Remote Digital The Remote Digital Loop with 511/511E is
Loop with shown below. After RDL is established the
511/511E Remote units' Restart Timer is set to one
minute. This has been done because when the
511/511E generator is started on the local unit,
the Remote framer begins seeing unframed
packets. The Remote unit can not distinguish
the 511/511E pattern from the line being disconnected so the Restart Timer has been lengthened to allow the pattern generator to function.
Once the 511/511E test is started, the Local unit
changes its' Restart Timer to one minute. The
pattern originates within the DSP and is sent to
the Remote unit. It is then looped back to the
Local unit where it is evaluated for errors. After
45 seconds, the Pattern Generator will timeout
and stops sending the pattern. The ER led will
begin blinking until the user turns off the
511/511E switch.

Data Mode with When the units enter DataMode it is possible to
511/511E Pattern turn on the 511/511E pattern generators on both
Generators ends of the link. Once a 511/511E pattern is
selected on one end of the link, the pattern generator will begin transmitting unframed 511/511E
through the line to the Remote end. A possible
problem with this test can occur due to the
Restart procedure. Once the Local 511/511E is
turned on, the Remote unit begins receiving an
unframed 511 pattern. If the Remote unit does
not turn on the 511/511E-pattern generator within 4 seconds, the Remote unit will Restart and
enter the StartUp mode. Note that once the
511/511E-pattern generator is started the
Restart timer is changed to one minute (only on
the unit which has the pattern enabled). If both
units enable the 511/511E pattern within 4 seconds of each other, both units will be transmitting and receiving the 511/511E pattern. Both
framers are now receiving unframed data and
will restart after one minute. The 511/511E pattern generators will TimeOut after 45 seconds
re-enabling the normal data path. The ER led
will begin flashing until the user terminates the
test.

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
1094ARC 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
1094ARC’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
1094ARC, and one to do the same at the remote Model 1094ARC.
In this case, the test pattern sent by each Model 1094ARC will
not be looped back, but will be transmitted down the line to the
other Model 1094ARC.
