2.2 GENERAL PRODUCT DESCRIPTION
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.
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 terminated 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 interface 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.

4.0 CONFIGURATION
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
The K Module has eight internal DIP switches (S1-1 through S1-8).
The DIP switches can be configured as either “On” or “Off.” See
Appendix D for location and orientation of the DIP switches.
Switch S1-1: Line Coding
Use Switch S1-1 to control the Network Line Coding options. Set
these options to be the same as the Line Coding that has been provided by your Service Provider.
S1-1 Line Framing & Coding
Off HDB3
On AMI
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.
S1-2 Option
Off Disabled
On Enabled
NOTE: When the data rate is set to 2048 Kbps, K Module trans-
mits user data on all 32 timeslots, ignoring framing information. In
this case, Switch S1-2 will be ignored.
9
10
Switch S1-3 : Clear Channel Mode
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 running 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.
S1-3 Option
Off Clear Channel Mode (G.703)
On Framed Mode (G.704)
Switch S1-4 Through S1-8 : Reserved
Reserved for future use and should be set to OFF.
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
).
2. For a 120 ohm connection (RJ-48C) remove JP4 - JP7.
4.3 Configuring Your Model 1095 mDSL Modem
This section describes how to configure your mDSL modem for
use with an IM1/K (Model 1095) or an IM2RC/K (Model 1095RC).
The K Module requires the 1095/1095RC to have software version 2.3.2 or later, which began shipping on 04/01/00.
If you are unsure of the software revision of your unit, please contact Patton Electronics Technical Support.
Clock Mode
The mDSL modem must be set for the External Clock mode when
a K Module is installed. The modem will always receive the clocking
from the K Module. If you are configuring a Network Extension application, 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 interface 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.
CO-CP
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.
Interface Type
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".
DTE Rate for the mDSL Modems
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.
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.

This section describes how to install the IM1/K and IM2RC/K modules into your mDSL modems. Please refer to the section in this manual 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.
5.1.1 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:
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 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 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.
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.
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 chassis.
4. Push the front card
gently
into the card-edge receptacle of the
rear card. It should “click” into place.
5. Secure the front card using the thumb screws.
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
arrow ( ) pointing toward the front panel. Please see the Model
1095RC User Manual (section 3.0 Configuration), for more information on installing the flip card.

CABLE RECOMMENDATIONS
All Patton Electronics Company Baseband Modems, CSU/DSUs
and Short Range Modem are tested to the distances published in our
Catalogs and Specification Sheets on twisted-pair cable with the following characteristics:
W
ire Gauge Capacitance Resistance
19 AWG 83nF/mi or 15.72 pF/ft. .0163 ohms/ft.
22 AWG 83nF/mi or 15.72 pF/ft. .0326 ohms/ft.
24 AWG 83nF/mi or 15.72 pF/ft. .05165 ohms/ft.
26 AWG 83nF/mi or 15.72 pF/ft. .08235 ohms/ft.
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 characteristics (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 numerous 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.
