The Patton Model IM1/K G.703/G.704 QuickConnect Module and  
IM2RC/K Rear Card Module provide E1/Fractional E1 termination and  
extension capabilities to the Patton NetLink mDSL modems  
(1095/1095RC). When used with a Patton mDSL modem, a  
G.703/G.704 line can be terminated or extended to a remote site up to  
10km away.

Figure 1. Clocking Settings in a Network Termination Application  
There are two separate applications that can be employed  
when using the K Modules; Network Termination or Network Extension.  
In a Network Termination application, the G.703/G.704 line is terminat-  
ed at the K Module and the clock and data is sent to the far end of the  
link. At the remote site, a Patton mDSL modem with a serial/Ethernet  
interface will be running the nx64 DTE rate. This application allows the  
remote user without a G.703/G.704 interface to extend the serial inter-  
face that is available to the G.703/G.704 access point without the need  
for a separate G.703/G.704 to serial converter. In the G.703/G.704  
Network Extension application, two K Modules are employed, one at  
each end of the link. This application allows the user to extend the  
G.703/G.704 network over 10km away.  
The K Module supports switch selectable AMI or HDB3 encoding,  
all nx64 kbps bit rates and both dual coaxial (75 ohm) and RJ-48C  
(120 ohm) G.703/G.704 terminations. The K Module is made in the  
USA. The K Module is CE marked and complies to applicable CTR  
standards.

3.2 NETWORK EXTENSION APPLICATION  
4.0 CONFIGURATION  
Network Extension mode is used to extend nx64 -2.048Mbps  
G.703/G.704 service across a DSL link, providing an nx64  
G.703/G.704 link at the remote site. Transmitter clocking is  
derived from the G.703/G.704 network, and transmitted over the  
baseband modem link (refer to Figure 2, below).  
The K Module features configuration capability via hardware  
switches and jumpers. Sections 4.1 and 4.2 describe all switch and  
jumper configurations for the Patton K Module. Section 4.3 describes  
the configuration required for your mDSL modem.  
4.1 DIP Switch Configuration  
K Module and

AMI  
Figure 2. Clock Settings in a Network Extension Application  
Line Coding Options:  
High Density Bipolar 3 (HDB3): In HDB3 coding, the transmitter  
deliberately inserts a bipolar violation when excessive zeros in the  
data stream are detected. The receiver recognizes these special  
violations and decodes them as zeros. This method enables the  
network to meet minimum pulse density requirements. Use HDB3  
unless AMI is required in your application .  
Alternate Mark Inversion (AMI): AMI coding does not inherently  
account for ones density. To meet this requirement, you should  
ensure that the data inherently meets pulse density requirements.  
Switch S1-2 : CRC-4 Multiframe  
CRC-4 Multiframe uses Time Slot zero to carry CRC-4 information.  
When CRC-4 is enabled (ON), the unit synchronizes to the CRC-4  
multi-frame protocol.

this case, Switch S1-2 will be ignored.

Switch S1-3 : Clear Channel Mode  
Clock Mode  
The mDSL modem must be set for the External Clock mode when  
When S1-3 is at Off position, the K Module is running in G.703  
clear channel mode. When S1-3 is at On position, the K Module is run-  
ning in G.704 framed mode. When the K Module is set to framed  
mode, channel 0 will be used to pass G.704 framing information which  
results in a maximum bandwidth of 1984kbps for user data.  
a K Module is installed. The modem will always receive the clocking  
from the K Module. If you are configuring a Network Extension applica-  
tion, set both modems for External Clock mode. If you are configuring  
a Network Termination application, please set the modem with the K  
Module for External Clock and the unit with the serial/Ethernet inter-  
face for Receive Recovered clock mode. In order to determine the  
switch settings specific to your unit, refer to the mDSL manual that was  
shipped with your unit.

Reserved for future use and should be set to OFF.  
The CO/CP selection tells the units which modem will begin the  
handshaking for the link. In all applications one unit must be set for CO  
and one unit must be set for CP, they work in pairs. A mDSL modem  
set for either Internal or External clock mode will automatically default  
to the CO mode. A mDSL modem set for Receive Recovered clock  
mode will automatically default to the CP mode. If you are configuring  
a Network Extension application, you must force one of the units to  
CP mode by setting S2-1 on the mDSL modem to the ON position.  
Note that the mDSL manual refers to this switch as "Reserved". If you  
are running in the Network Termination mode, no extra configuration is  
required.  
4.2 Jumper Configuration  
The Patton K Module has four jumpers (two position headers):  
JP4, JP5, JP6, and JP7. These jumpers are used to select input and  
output impedance matching between the module and external line. See  
Appendix E for jumper locations.  
The following is a description of the jumper settings with respect  
to the front panel connectors.  
1. For a 75 ohm connection (coax) install JP4 - JP7 (default).  
Interface Type  
2. For a 120 ohm connection (RJ-48C) remove JP4 - JP7.  
The mDSL modem requires that the interface type is specified.  
Any unit that has a K Module installed must be set to G.703/G.704  
Interface. This is done by setting S2-5 on the mDSL modem to ON.  
Note that the mDSL manual refers to this switch as "Reserved".  
4.3 Configuring Your Model 1095 mDSL Modem  
DTE Rate for the mDSL Modems  
This section describes how to configure your mDSL modem for  
use with an IM1/K (Model 1095) or an IM2RC/K (Model 1095RC).  
To select the number of G.703/G.704 channels to be carried  
across the link, multiply the number of required channels by 64Kbps  
and then set the DTE rate of the mDSL modem to that number. The  
mDSL modem will then carry that number of channels from the  
G.703/G.704 line, starting with channel 1 (Note channel 0 is used for  
G.704 framing information) across the DSL link. For example, if you  
want to carry 4 channels across the DSL link, set the mDSL DTE Rate  
to 256Kbps (4 x 64Kbps = 256Kbps). The mDSL modem and the K  
Module will then carry channels 1 - 4 across the DSL link.  
The K Module requires the 1095/1095RC to have software ver-  
sion 2.3.2 or later, which began shipping on 04/01/00.  
If you are unsure of the software revision of your unit, please con-  
tact Patton Electronics Technical Support.  
If you are running in clear channel mode, set switch S1-3 on the K  
Module to "clear channel" and set the DTE Rate of your mDSL modem  
to 2048Kbps.

Installing the New QuikConnect™ Module  
5.0 INSTALLATION  
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 NetLink  
Chassis.  
3) While keeping the module’s faceplate parallel with the NetLink  
chassis 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 mod-  
erate and even pressure should be sufficient to seat the mod-  
ule. You should hear it “click” into place.  
This section describes how to install the IM1/K and IM2RC/K mod-  
ules into your mDSL modems. Please refer to the section in this manu-  
al that describes your unit.  
5.1 Installing the IM1/K  
The QuickConnect™ interface on the NetLink Modems are inter-  
changeable Modules. Each QuikConnect™ Module has a 50-pin card  
edge connector on one side and a Network interface on the other.  
Figure 3 below shows how a QuikConnect™ Module plugs into the  
back of the Model 1095.  
5) To secure the module in place, push the thumbscrews into the  
chassis and turn the screws clockwise to tighten.  
5.2 Installing the IM2RC/K and Front Fuction Card  
The Model IM2RC/K is a rear-mountable G.703/G.704 interface  
card that works with the Patton Model 1095RC function card. The two  
cards meet inside the rack chassis and plug into each other by way of  
mating 50 pin card edge connectors. Use the following steps as a  
guideline for installing each Model IM2RC/K and its function card mate  
into the rack chassis:  
1. Slide the rear card into the back of the chassis along the  
metal rails provided.  
Figure 3. Installation of Model 1095 Plug-in K Module  
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.  
5.1.1 Changing QuikConnect™ Modules  
When you purchase a NetLink™ mDSL modem, it should be  
shipped to you with the appropriate QuikConnect™ Module already  
installed. If you need to install a different QuikConnect™ Module, fol-  
low these steps:  
5. Secure the front card using the thumb screws.  
Removing the Existing QuikConnect™ Module  
The IM2RC/K is shipped with an IM1RC/K flip card. Ensure that  
the flip card is secured in the flip card socket on the 1095RC with the

We fully expect that the Baseband Modems, CSU/DSUs and Short  
Range Modems will operate on lines with specifications different from  
those tested, but to reduce the potential difficulties in the field, one  
should ensure that the cable being used has similar or better charac-  
teristics (lower capacitance or lower resistance).  
Wire with capacitance of 20pF/ft. or less is suitable for all  
Baseband Modems, CSU/DSUs and Short Range Modems. However,  
distances may vary from those published in our catalog. Resistance  
will also affect distance but not functionality. Wire should be 26 AWG  
or larger (smaller AWG#).  
Patton products are designed to withstand normal environmental  
noise and conditions; however, other environmental factors too numer-  
ous to discuss in this format may affect proper operation.  
Selection of the proper Baseband Modem, CSU/DSU or SRM for  
an application is critical to maintaining Customer Satisfaction and must  
be taken seriously. Certain models are better suited for particular  
applications and environments than others.
