2.2 DESCRIPTION
The Patton Electronics
NetLinkTMModel 1095 mDSL
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 “megabyte”speeds
to leased line, LAN to LAN interconnection, and WAN access networks
over 3.6 miles/5.8km (1.054Mbps on 24AWG/.5mm wire). The Model
1095 mDSL standalone allows DTE speeds from 64 kbps to 2.3 Mbps
in increments of 64kbps. Features include loopback diagnostics, in-band
SNMP/HTTP remote management capabilities using NetLink Plug-andPlay, and externally accessible configuration switches.
A high density 2U-high rack card version of the Model 1095 mDSL
is also available.As a symmetric DSL NTU, the Model 1095 offers the
same data rates in both directions over a single pair of voice-grade
telephone lines using Carrierless Amplitude and Phase (CAP) modulation. Featuring replaceable DCE-DTE interface modules, the NetLink
mDSL can be configured for a huge range of V.24/RS-232, V.35, RS422/530, G.703 and X.21 applications.The standard Model 1095 is
powered by a 100/230 VAC (Universal) supply. The DC power supply
option supports any DC input between 36–72 VDC.Using the NetLink
Plug-and-Play feature, the standalone unit at the Customer Premise
site will automatically configure itself to the DTE rate of the rack card
at the Central Office. Other configuration parameters fall to the default
state.This allows changes in the configuration to be handled from a
single end of the link.

3.2 CONFIGURING THE SOFTWARE SWITCHES
The Model 1095 features a menu-driven command system that
allows you to monitor and configure your Model 1095 stand alone unit.
There are two modes of operation for the Model 1095 control port:
Monitor and Configuration.These are described in more detail below.
Following the Model 1095 setup is a description of how to setup your
VT100, or equivalent, control port for use with the Model 1095.
3.2.1 Monitor
If you are configuring your Model 1095 through the dip-switches
and you wish to check your configuration or view the status of the
modem you can do so by accessing the control port. In this setup the
user is not able to make configuration changes to the unit because the
hardware dip-switch settings are controlling the configuration of the
unit. If you would like to use the control port to configure your unit see
the Configuration section below for setup information.
3.2.2 Configuration
If you plan to use the Model 1095 control port to configure your
unit, you mus set all of the DIP switches to the ON position.This will
force the 1095 into plug-and-play mode (this configuration is also
required if you intend to have the Model 1095 work in a plug-and-play
environment or use the Model 1001MC to configure the unit).
3.2.3 VT100 Terminal Setup
1) Connect the serial RS-232 port of a VT100 or similar DTE with terminal emulation to the EIA/TIA-561 port of the Model 1095. To construct
an RS-232 to EIA-561 patch cable, refer to the control port pinout diagram in Appendix F.Refer to Appendix B to order a pre-made cable.
2) Power up the terminal and set its RS-232 port as follows:
9600 Baud
8 data bits, 1 stop bit, no parity
Local echo
CR-CR/LF on inbound data
ANSI, VT-100 emulation
3) Power up the Model 1095
4) After power up, the control port displays the Main Menu screen.If the
Main Menu is not shown please review your VT100 setup as described
above.

3.4 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 automatically
configure itself to the DTE rate of the rack card. Other configuration
parameters fall to the default state. This allows changes in the configuration to be handled from a single end of the link.
When installing a CO/CP style application, the local end of the link
is comprised of a CO unit (1095RC) set to either Internal or External
clocking mode and a CP unit (1095) 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 3).
When the units are connected, the CP will come up with a predefined default configuration (Receive Recovered Clocking). During the
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 settings. If the DTE rate for the link requires a change, the change is
needed only at the CO side of the link.
The NetLink Plug and Play application will also work in the managed system using the Model 1001MC and 1095RC cards installed in
Patton’s 2U rack system. In this application, the system administrator
can configure the entire rack through the Network Management Station
(NMS) before the stand alone (CP) units are installed. For more information on the SNMP management of your rack, please refer to the
Model 1001MC Operations Manual.

4.0 INSTALLATION
Once the Model 1095 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 1095 supports communication between two DTE
devices at distances to 5 miles (8 km) over 24 AWG (.5mm) twisted
pair wire. There are two essential requirements for installing the Model
1095:
1. These units work in pairs. Both units at the end of the twisted
pair must have the same 2-Wire connection and DTE rate.
2. To function properly, the Model 1095 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 modular telephone type cable, are
not acceptable
.
The RJ-45 connector on the Model 1095’s twisted pair interface is
polarity insensitive and is wired for a two-wire interface. The signal/pin
relationships are shown in Figure 4 below.

4.2 CONNECTING THE SERIAL PORT
The serial port interface on the Model 1095 uses interchangeable
QuikConnect™
Modules. Each
QuikConnect™
Module has a 50-pin
card edge connector on one side and a serial port interface on the
other. Figure 4 below shows how a
QuikConnect™
Module plugs into
the back of the Model 1095.
4.2.1 Changing
QuikConnect™
Modules
When you purchase a particular version of the Model 1095, it
should be shipped to you with the appropriate
QuikConnect™
Module
already installed. If you need to install a different
QuikConnect™
Module, follow these steps:
Removing the Existing
QuikConnect™
Module
1) Turn the power switch off. Leave the power cord plugged into a
grounded outlet to keep the unit grounded.
2) Loosen the two thumbscrews on the module by turning them
counterclockwise.
3) Grasp the two thumbscrews and gently pull the module from
the unit. Apply equal force to the thumbscrews to keep the
module straight during the removal process
Installing the New
QuikConnect™
Module
1) Make sure the power switch is off. Leave the power cord
plugged into a grounded outlet to keep the unit grounded.

2) Hold the module with the faceplate toward you and align the
module with the guide slots in the rear panel of the Model
1095.
3) While keeping the module’s faceplate parallel with the Model
1095 rear panel, slide the module straight in – so that the card
edge contacts line up with the socket inside the chassis.
4) With the card edge contacts aligned with the socket, firmly seat
the module by using your thumbs to apply pressure directly to
the right and left edges of the module faceplate. Applying moderate and
even
pressure should be sufficient to seat the mod-
ule. You should hear it “click” into place.
5) To secure the module in place, push the thumbscrews into the
chassis and turn the screws clockwise to tighten.
4.2.2 Connecting to a “DTE”Device
The serial port on most
QuikConnect™
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 ter minal, 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.
4.2.3 Connecting to a “DCE”Device
If the Model 1095’s QuikConnect™ 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.
NOTE: The card edge connector should meet the socket when
it is almost all the way into the chassis. If you encounter a lot of
resistance, remove the module and repeat steps 2 & 3.
NOTE: Pin-out requirements for null modem applications vary
widely between manufacturers. If you have any questions about
a specific application, contact Patton Electronics Technical
Support.
4.2.4 Configuring the X.21
QuikConnect™
Module
The serial port on the X.21
QuikConnect™
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 module according to
the instructions in Section 4.2.1. The DCE/DTE strap is located on the
bottom side of the 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 DB-15 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 4.2.1.
4.3 CONNECTING POWER
The Model 1095 is available with two power supply options:
Universal Interface AC Power Supply option (Model 1095-UI)
operates in environments ranging from 100 to 253 VAC, with no reconfiguration necessary (see Appendix B for available domestic and
international power cords).
DC Power Supply option (Model 1095-DC) operates in 48 VDC
environments and is equipped with a 3-pin “terminal strip” style connector.
4.3.1 Connecting to an AC Power Source
The Universal Interface AC Supply is equipped with a male IEC-
320 power connection. A domestic (US) power supply cord is supplied with the unit at no extra charge. To connect the standard or universal power supply, follow these steps:
1) Attach the power cord (supplied) to the shrouded male IEC320 connector on the rear of the Model 1095.
2) Plug the power cord into a nearby AC power outlet.
3) Turn the rear power switch ON.
19
20
4.3.2 Connecting to a DC Power Source
The 48 VDC power supply option uses a 3-pin terminal block with
spring-type connectors. Please refer to the Model 1090 Series Service

5.0 OPERATION
Once the Model 1095 is properly configured and installed, it
should operate transparently. This sections describes power-up, reading the LED status monitors, and using the built-in loopback test
modes.
5.1 POWER-UP
To apply power to the Model 1095, first be sure that you have read
Section 4.3, and that the unit is connected to the appropriate power
source. Then power-up the unit using the rear power switch.
5.2 LED STATUS MONITORS
The Model 1095 features eight front panel LEDs that monitor
power, the DTE signals, network connection and test modes. Figure 6
(below) shows the front panel location of each LED. Following Figure
5 is a description of each LEDs function. (See also, Appendix E.)
TD & RD Glows yellow to indicate an idle condition of Binary
“1” data on the respective terminal interface signals. Green indicates Binary “0” data
CTS Glows green to indicate that the Clear to Send sig-
nal from the modem is active.
CD Glows yellow 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.

placed in test mode by the local user or by the
remote user. The TM LED will flash for 400msec
when a valid packet is received from the Model
1001MC.
NS (No Signal) glows red to indicate that the local
Model 1095 is not connected with the remote
Model 1095.
5.3 TEST MODES
The Model 1095 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 DTE interface.
5.3.1 Overview
Figure 6 below shows the major elements used in the loop-back
and pattern tests available in the Model 1095.Each block has several
functions. Following Figure 7 are descriptions that show how the elements are used during Test Modes.

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 par t 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 patter n 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.

termination of a data path. The direction of the

5.3.2 Loops and Patterns
The following section describes the Test Modes used in the Model
1095. 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 interface 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 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
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 8. Block Diagram Local Loop Mode 1
Figure 9. 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
activated, 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
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 impor tant 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 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
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 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.

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 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
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 tur n on the 511/511E patter n 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 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.

5.3.3 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
1095 and move it DOWN. 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 UP, activating the “511/E” test with
errors present. If the test is working properly, the local
modem's red “ER” LED will blink. 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.
NOTE:The above V.52 BER tests can be used independently of
the Remote Digital Loopback tests. This requires two operators:
(1) to initiate and monitor the tests at the local Model 1095, and
(2) to do the same at the remote Model 1095. In this case, the
test pattern sent by each Model 1095 will not be looped back, but
will be transmitted down the line to the other Model 1095. While
one operator initiates test, the other monitors for errors.
