The Model 1089 is equipped with two sets of eight DIP switches,
which allow configuration of the unit for a wide variety of applications.
This section describes switch locations and explains all possible con-
figurations.
3.1 CONFIGURING THE HARDWARE DIP SWITCHES
The 16 external switches are grouped into two eight-switch sets,
and are externally accessible from the underside of the Model 1089
(See Figure 1).
The two sets of DIP switches on the underside of the Model 1089
will be referred to as S2 and S3. As Figure 2 shows, the orientation of
all DIP switches is the same with respect to “ON” and “OFF” positions.

Switch S2-8: Enable/Disable Loop Tests from DTE
Switch S2-8 may be used to allow Model 1089/C to enter loopback
diagnostic tests (Local or Remote) when the V.35 DTE raises the
appropriate loop request pin (LLB: Pin L or RDL: Pin N). When Switch
S2-8 is in the On position, the Model 1089/C will enter Local Loopback
or Remote Loopback at the request of the DTE. When Switch S2-8 is
in the Off position, the Model 1089/C ignores DTE loop requests. In
the Off position, loop requests may still be initiated by the front panel
switch.

Once the Model 1089 is properly configured, it is ready to connect
to the twisted pair interface, to the serial port, and to the power source.
This section tells you how to make these connections.
4.1 CONNECTING THE TWISTED PAIR INTERFACE
The Model 1089 supports communication between two DTE
devices at distances to 5 miles (8 km) over 24 AWG (.5mm) twisted
pair wire. Two things are essential:
1. These units work in pairs. Both units at the end of the twisted
pair DSL span must be set for the same DTE rate.
2. To function properly, the Model 1089 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 will limit distance).
Standard dial-up telephone circuits, or leased circuits that run
through signal equalization equipment, or standard, flat modu-
lar telephone type cable, are not acceptable.
The RJ-45 connector on the Model 1089’s twisted pair interface is
polarity insensitive and is wired for a two-wire interface. The signal/pin
relationships are shown in Figure 3 below.
NOTE: Based on the DTE rate chosen, the Model 1089 will
automatically select the optimum line rate depending on dis-
tance and line conditionsfor the distance. The line selection will
be based on the lowest line rate that will support the DTE rate.

IMPORTANT!: The Model 1089 has been optimized for per-
formance at high bitrates (DTE rates greater than 512 kbps). To
ensure accurate performance at these bit rates, please use twist-
ed pair line interface cable that is at least 330ft (100m) in length.

4.2 CONNECTING THE MODEL 1089/C (V.35) SERIAL INTERFACE
Model 1089/C supports V.35 serial port connections. This section
describes how to connect the serial ports to your V.35 equipment.
4.2.1 Connecting the Model 1089/C (V.35) to a “DTE” Device
The Model 1089/C provides a V.35 DCE (Data Circuit Terminating
Equipment) interface on an M/34 female connector. As a DCE, this
interface is designed to connect to DTE equipment, such as a router.
When connecting the V.35 interface of the Model 1089/C to your DTE
device, use a V.35 straight through cable (See Figure 4, below).
Appendix C describes pin assignments and signal sources for the
Model 1089/C V.35 interface. When purchasing or constructing an
interface cable, please refer to the pin diagrams in Appendix C as a
guide.
4.2.2 Connecting the Model 1089/C (V.35) to a “DCE” Device
The Model 1089/C provides a V.35 (Data Circuit Terminating
Equipment) interface on an M/35 female connector. As a DCE, this
interface is designed to connect to DTE equipment, such as a router.
However, tail-circuit applications require connection to another DCE
equipment, such as a multiplexer. When connecting the V.35 interface
of the Model 1089/C to your DCE device, use a V.35 null modem
cable. Some applications may also required the installation of a V.35
tail-circuit buffer to account for small differences in clock frequency
between the 1089/C and the V.35 DCE (multiplexer).
4.3 CONNECTING THE MODEL 1089/D (X.21) SERIAL INTERFACE
Model 1089/D supports X.21 serial port connections. This section
describes how to connect the serial ports to your X.21 equipment.
4.3.1 Connecting the Model 1089/D (X.21) to a “DCE” or “DTE”
Device
The Model 1089/D provides an X.21 interface on a DB-15 female
connector. The X.21 interface default configuration is DCE (Data
Circuit Terminating Equipment) for connection to DTE (Data Terminal
Equipment) such as a router. However, the X.21 interface on the
Model 1089/D may be configured as DTE (Data Terminal Equipment)
for connection to DCE such as a modem or multiplexer. When con-
necting the X.21 interface of the Model 1089/C to your DTE device,
use a X.21 straight through cable (See Figure 6, below).
To modify the DCE/DTE orientation from the default position
(DCE), you must open the Model 1089/D case.
4.3.1 Opening the Case
To open the Model 1089/D case, insert a flat head screw driver
into an open slot on both sides of the case, as in Figure 7. Twist the
screw driver head slightly and the top half of the case will separate
from the lower half, as in Figure 7, below. Take caution not to dam-
age of the pc-board mounted components.

The DCE/DTE strap is located on the top side of the 1089/D pc
board (See Figure 8, below). The arrows on the top of the strap indi-
cate the configuration of the X.21 port (for example, if the DCE arrows
are pointing toward the DB-15 connector, the X.21 port is wired as a
DCE). Change 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 direc-
tions, showing the new configuration of the X.21 port. To close the
case, fit the 2 halves together snugly and snap them back in place.
4.4 CONNECTING POWER
The Model 1089 (all versions) are available with Universal AC
(100-240VAC), 120VAC, 230VAC or -48VDC power options. This sec-
tion describes these options.
4.4.1 Universal AC Power (100-240VAC)
The Model 1089 uses a 5VDC, 2A universal input 100-240VAC,
power supply (center pin is +5V). The universal input power supply
has a male IEC-320 power entry connector. This power supply con-
nects to the Model 1089 by means of a barrel jack on the rear panel.
Many international power cords are available for the universal power
supply (Please refer to Appendix B for country-specific power cords.
The Model 1089 powers up as soon as it is plugged into an AC
outlet--there is no power switch.
13
4.4.2 120 VAC Power (US)
The 100-132 VAC adapter supplied with the U.S. version of the
Model 1089 is a wall mount type and may be plugged into any

ing the LED status monitors, and using the built-in loopback test
modes.
5.1 POWER-UP
To apply power to the Model 1089, first be sure that you have
read Section 4.4. The unit powers up when it is plugged into the
power source.
5.2 LED STATUS MONITORS
The Model 1089 features six 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. See also, section

Figure 11: Block Diagram Model 1089
Framer The framer is used to determine the status of
the line. In normal operation the framer trans-
mits 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 con-
nection is made (cable disconnect, poor cable
quality, etc). In normal Data Mode, if the Model
1089 receives 4 seconds of unframed packets it
will restart 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 transmit-
ting 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.
17
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 rea-
son 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.

5.3.2 Loops and Patterns
The following section describes the Test Modes used in the Model
1089. 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 in 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 7.
When the Local Loop is initiated, either by the
front panel switch or the DTE interface, the loop
will be activated within the local Processor. 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 inter-
face is invalid. The remote unit will remain in the
StartUP mode, NS LED on, CTS LED yellow,
and CD LED yellow, until the local unit is taken
out of the Local Loop 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 8.
When the Local Loop is initiated, either by the
front panel switch or the DTE interface, two sep-
arate 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
and 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
re-established.

Figure 13. 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 send-
ing 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 discon-
nection (this would cause the units' Restart pro-
cedure to start). What we have done to allow
this mode to work is to add time outs for the pat-
tern 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 dur-
ing a local loop, the restart procedure is set to
one minute, but the 511/511E pattern will time
out after 45 seconds, allowing the framer to
begin seeing framed packets (and not restart
the box).

Local Loop After the 511/511E pattern times out, the ER led
with 511/511E will begin flashing. It will remain this way until
(continued) the pattern generator switch is turned off. Note
that the data at the 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 11, the 511/511E pattern
generator has no data path connections avail-
able. The 511/511E pattern generator is still
available on the remote unit. For more informa-
tion on the proper operation of this pattern gen-
erator 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
PROCESSOR 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 explain in the
RDL with 511/511E section). If the line is discon-
nected, the local unit will Restart (NS led activat-
ed) 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.

Remote Digital The Remote Digital Loop with 511/511E is
Loop with shown above. 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 discon-
nected so the Restart Timer has been length-
ened 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 Processor 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
Generators both 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 sec-
onds of each other, both units will be transmit-
ting and receiving the 511/511E pattern. Both
framers are now receiving unframed data and
will restart after one minute. The 511/511E pat-
tern generators will TimeOut after 45 seconds
re-enabling the normal data path. The ER led
will begin flashing until the user terminates the
test.

5.3.3 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
1089 and move it UP. 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 DOWN, 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
1095’s built-in “511” generator and detector are working
properly.

of the Remote Digital Loopback tests. This requires two opera-
tors: (1) to initiate and monitor the tests at the local Model 1089,
and (2) to do the same at the remote Model 1089. In this case,
the test pattern sent by each Model 1089 will not be looped back,
but will be transmitted down the line to the other Model 1089.
While one operator initiates test, the other monitors for errors.
