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  
Internal  
}
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

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.  
4.3.2 Two-Wire Cable Connection Via RJ-45  
1.  
The RJ-45 connector on the Model 1095RC’s twisted pair  
interface is polarity insensitive and is wired for a two-wire  
interface.The signal/pin relationships are shown in Figure 11  
below.

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.  
- flashes once to indicate that a CRC error has  
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.  
TM  
glows yellow to indicate that the Model 1095RC  
has been placed in Test Mode. The unit can be  
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.

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.

glows yellow to indicate an idle condition of Binary  
“1” data on the respective terminal interface  
signals. Green indicates Binary “0” data.  
5.2.1 Overview  
Figure 12 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 13 are descriptions that show how the ele-  
ments are used during Test Modes.  
CTS  
consists of 2 LEDs, 1 yellow, 1 green. CTS glows  
green to indicate that the Clear to Send signal  
from the modem is active. Yellow indicates inac-  
tive CTS.

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.

This symbol designates the origination or the termination of a data  
path. The direction of the arrow connected dis-

there is data present it should be ignored.

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.

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.

*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.
