2.2 DESCRIPTION
The Patton Electronics NetLinkTM mDSL Model 1095RC Multi-
Rate DSL Modem provides high speed 2-wire connectivity to ISPs,
PTTs, and corporations using mDSL (Multi-rate Digital Subscriber Line)
technology. Multi-rate DSL offers the ability to deliver the maximum bit
rate that a twisted pair line can accommodate. Supporting multiple line
rates from 144kbps to 2.320Mbps, the NetLink provides “megabit”
speeds to leased line, LAN to LAN interconnection, and WAN access
networks over 3.6 miles/5.8km (1.054Mbps on 24AWG/.5mm wire).
IMPORTANT: The Model 1095RC is equipped with flash
upgrade. Please refer to Patton website, or contact Technical
Support for the latest version of the software.
The NetLinkTM mDSL rack card allows DTE speeds from 64kbps
to 2.3Mbps in increments of 64kbps. Features include loopback diag-
nostics, out-of-band SNMP/HTTP remote management capabilities,
using Model 1000MC, and externally accessible configuration switch-
es.
As a symmetric DSL NTU, NetLinkTM mDSL offers the same data
rates in both directions over a single pair of regular telephone lines
using Carrierless Amplitude and Phase (CAP) modulation. The Model
1095RC is designed to fit into Patton’s 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 that are
available.
The NetLink Plug-and-Play feature allows the user to configure the
DTE rate for the link from the rack card at the Central Office. The
stand alone unit at the Customer Premise site will automatically config-
ure itself to the DTE rate of the rack card. Other configuration parame-
ters fall to the default state. This allows changes in the configuration
to be handled from a single end of the link.

3.0 CONFIGURATION
3.1.1 Reversible Interface Driver Board
This section describes the location and orientation of the Model
1095RC’s configuration switches and jumpers, and provides detailed
instructions for all possible settings.
The Model 1095RC 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 1095RC PC board.
3.1 CONFIGURING THE HARDWARE SWITCHES
The Model 1095RC Series front card uses hardware switches for
configuration. There is an interface driver board strap, and three eight-
position DIP switches, on the bottom side of the front card (see Figure
1, below).

Follow the instructions below to select the correct interface for your
application:
1. With the 1095RC front card pulled out of the rack or cluster-
box chassis, locate the driver board on the top of the 1095RC
front card.
Figure 1. Model 1095RC, showing configuration switches and interface board
2. Lift the interface board gently off of the PC board.
Figure 2 shows the orientation of the DIP switches with respect to
the “ON” and “OFF” positions.
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.
ON
4. Re-orient the interface board into the socket with the appropri-
ate interface pointed UP and with the arrow pointing toward
the front panel of the Model 1095RC PC board.
OFF

3.1.2 Connecting to a “DTE” Device
3.1.5 Configuration DIP Switch Set “S1” - Management Address
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 pur-
chasing or constructing an interface cable, please refer to the pin dia-
grams in Appendix C as a guide.
Switch S1 is used to set the address of the card in the NetLink
Network Management System. When the 1095Rc is installed with a
Model 1001MC, the cards and their remote units can be SNMP man-
aged using a standard Network Management Station (NMS) or a stan-
dard web browser (Netscape, Internet Explorer). For more information
about setting the address, refer to Appendix a of the Model 1001
Operations Manual.
NOTE: If you are not using your Model 1095RC in a Network
Managed environment, please set all Switch Set S1 switches
to the ON position
3.1.3 Connecting to a “DCE” Device
If the Model 1095RC interface module is hard-wired as a DCE (all
except the X.21 module), you must use a null modem cable when con-
necting 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.
3.1.6 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 set-
tings of S2 are shown in the table below.
NOTE: Pin-out requirements for null modem applications vary

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 ori-
entation of the DCE/DTE strap, as described below:
On
On

}
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.

3.2 NETLINK PLUG-AND-PLAY
The NetLink Plug-and-Play application allows ISPs and PTTs to
quickly upgrade the link speed for a customer without re-configuring
the Customer Premise (CP) Model 1095. It will also allow ISPs and
PTTs to set up all of the configurations at the Central Office (on the
rack cards) before installation of the stand alone units, thus saving
time spent configuring and re-configuring DIP switch settings.
The NetLink Plug-and-Play feature allows the user to configure
the DTE rate for the link from the rack card at the Central Office (CO).
The stand alone unit at the Customer Premise (CP) site will automati-
cally configure itself to the DTE rate of the rack card. Other configura-
tion parameters fall to the default state. This allows changes in the
configuration to be handled from a single end of the link.
NOTE: Based on the DTE rate chosen, the Model 1095RC will
automatically select the optimum line rate for the distance. This
selection is based on the lowest line rate that will support the
DTE rate.
When installing a CO/CP style application, the local end of the link
is comprised of a CO unit (1095 or 1095RC) set to either Internal or
External clocking mode and a CP unit (1095 or 1095RC) set as a
NetLink Plug-and-Play CP. The NetLink Plug-and-Play CP stand
alone will have all of its DIP switches set to the ON position (as
indicated below in Figure 4).
Switch S3-7: Reset Software Defaults
Switch S3-7 allows the user to reset the software configured facto-
ry defaults. This will only be needed when using the Model 1001MC to
SNMP manage your units. For more information, please refer to the
Model 1001MC Operations Manual.

handshaking process between the units, the CO unit will set the DTE
rate/line rate of the CP unit to match its DIP switch configuration set-
tings. If the DTE rate for the link requires a change, the change is
needed only at the CO side of the link.

3.3 CONFIGURING THE REAR INTERFACE CARD
Prior to installation, you will need to examine the rear card you have
selected and make sure it is properly configured for your application.
Each rear card is configured by setting straps located on the PC board.
To configure the rear cards, you must set the configuration straps.
Figure 6 below shows the orientation of these straps. Each strap can
either be on pegs 1 and 2, or on pegs 2 and 3.
The Model 1095RC Series has six interface card options: the
Model 1001RCM12545 (DB-25/RJ-45), the Model 1001RCM13445
(M/34/RJ-45), the Model 1001RCM125TB (DB25/TB), the Model
1001RCM134TB (M/34/TB), the Model 1001RCM11545, and the Model
1001RCM115TB. Each of these options supports one DTE interface
connection and one 2-wire line connection. Figure 5 below illustrates
the six different interface options for the Model 1095RC Series.

4.0 INSTALLATION
Powering Up Your 1001R14 Rack
This section describes the functions of the Model 1001R14 rack
chassis, tells how to install front and rear Model 1095RC Series cards
into the chassis, and how to connect to the twisted pair interface and
the serial interface.
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 sys-
tem.
4.1 THE MODEL 1001R14 RACK CHASSIS
The Model 1001R14 Rack Chassis (Figure 10, below) has four-
teenshort 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.
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
1001R14 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 1001RP14 Series User
Manual AC & DC Rack Mount Power Supplies for fuse and
power card replacement information.
4.2 INSTALLING MODEL 1095RC SERIES INTO THE CHASSIS
The Model 1095RC 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 follow-
ing steps as a guideline for installing each Model 1095RC Series into
the rack chassis:
Figure 10: Model 1001R14 Rack Chassis with power supply
1. Slide the rear card into the back of the chassis along the
metal rails provided.
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.
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.
WARNING! There are no user-serviceable parts in the
power supply section of the Model 1095RC 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.
5. Secure the front card using the thumb screws.
4.3 WIRING THE MODEL 1095RC SERIES
Each of the rear interface cards compatible with the Model
1095RC 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
4.3.3 Two-Wire Cable Connection Via Terminal Block
The Model 1095RC 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 1095RC:
The two pin terminal block connector on the Model 1095RC’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.
1. These units work in pairs. Therefore, you must have one
Model 1095RC (or a compatible model) at each end of a sin-
gle twisted pair interface.
Notice! Any modular twisted pair cable connected to
the Model 1095RC must be shielded cable, and the outer
shield must be properly terminated to a shielded modular
plug on both ends of the cable.
2. To function properly, the Model 1095RC 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.

5.0 OPERATION
ER
- blinks ON/OFF after a 511/511E test has timed
out. See Section 5.2.3 (Test Pattern Generator) for
more information.
Once the Model 1095RC 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.

occurred (during normal operation) or bit errors
have occurred (during 511/511E test).
5.1 LED STATUS INDICATORS
- Only at power up, blinks once every 200 ms if
the DTE Rate is set to an unsupported setting.
The Model 1095RC features twelve front panel LEDs that monitor
power, the DTE signals, network connection and test modes. Figure
12 (below) shows the front panel location of each LED. Following
Figure 10 is a description of each LEDs function.

5.2 TEST MODES
The Model 1095RC 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 acti-
vated physically from the front panel or via the interface.

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 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.
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.
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.

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 dese-
lected, the units will both be in StartUP mode
and the link will be established.

Local Loop
with 511/511E
When the unit is placed into a Mode 1 Local
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). After the 511/511E pattern times out, the
ER led will begin flashing.
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 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 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.

Local Loop
with 511/511E
(continued)
It will remain this way until 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.
Remote Digital
Loop
The Remote Loop uses the EOC channel (an
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.
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 15, 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
Loop with
511/511E
The Remote Digital Loop with 511/511E is
shown below. After RDL is established the
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 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
511/511E Pattern
Generators
When the units enter DataMode it is possible to
turn on the 511/511E pattern generators on both
ends of the link. Once a 511/511E pattern is
selected on one end of the link, the pattern gen-
erator 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 with-
in 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.

1. Locate the “511/511E” toggle switch on the front panel of the
1095RC 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.

DTE Rates:
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
1095RC’s built-in “511” generator and detector are working
properly.
Diagnostics:
*NOTE: The above V.52 BER tests can be used independently
of the Remote Digital Loopback tests. This requires two opera-
tors: (1) to initiate and monitor the tests at the local Model
1095RC, and (2) to do the same at the remote Model 1095RC. In
this case, the test pattern sent by each Model 1095RC will not be
looped back, but will be transmitted down the line to the other
Model 1095RC.
