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

Line Framing & Coding

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.

NOTE: When the data rate is set to 2048 Kbps, K Module trans-

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

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.
