1.1 RADIO AND TV INTERFERENCE

The Model 1094ARC generates and uses radio frequency energy,
and if not installed and used properly—that is, in strict accordance with
the manufacturer's instructions—may cause interference to radio and
television reception. The Model 1094ARC has been tested and found
to comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that interfer­ence will not occur in a particular installation. If the Model 1094ARC
does cause interference to radio or television reception, which can be
determined by disconnecting the unit, the user is encouraged to try to
correct the interference by one or more of the following measures:
moving the computing equipment away from the receiver, re-orienting
the receiving antenna and/or plugging the receiving equipment into a
different AC outlet (such that the computing equipment and receiver
are on different branches). In the event the user detects intermittent or
continuous product malfunction due to nearby high power transmitting
radio frequency equipment, the user is strongly advised to take the fol­lowing steps: use only data cables with an external outer shield bond­ed to a metal or metalized connector; and, configure the rear card as
shown in section 3.2 of this manual.

1.2 CE NOTICE

The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the European Union.

2.2 DESCRIPTION
The Patton Electronics

NetLinkTMHDSL

Model 1094ARC Multi-

Rate DSL Modem provides high speed 2-wire connectivity to ISPs,
PTTs, and corporations using HDSL technology. HDSL offers the abili­ty to deliver the maximum bit rate that a twisted pair line can accom­modate. Supporting

multiple line

rates from 144kbps to 1168Mbps, the
NetLink provides “megabit” speeds to leased line, LAN to LAN inter­connection, and WAN access networks over 2.9 miles/4.7 km
(1.152Mbps on 24AWG/.5mm wire).

The

NetLink

TM

HDSL

rack card allows

DTE speeds

from 64kbps
to 1.152Mbps in increments of 64kbps. Features include loopback
diagnostics, out-of-band SNMP/HTTP remote management capabili­ties, using Model 1000MC, and externally accessible configuration
switches.

As a symmetric DSL NTU,

NetLink

TM

HDSL

offers the same data
rates in both directions over a single pair of regular telephone lines
using 2B1Q modulation. The Model 1094ARC 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.

IMPORTANT: The Model 1094ARC is equipped with flash

upgrade. Refer to Patton website http://www.patton.com or

This section describes the location and orientation of the Model
1094ARC’s configuration switches and jumpers, and provides detailed
instructions for all possible settings.

3.1 CONFIGURING THE HARDWARE SWITCHES

The Model 1094ARC Series front card uses hardware switches for
configuration. There is an interface driver board strap, and three eight­position DIP switches, on the bottom side of the front card (see Figure
1, below).

Figure 2 shows the orientation of the DIP switches with respect to

the “ON” and “OFF” positions.

3.1.1 Reversible Interface Driver Board

The Model 1094ARC 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 1094ARC PC
board.

Follow the instructions below to select the correct interface for your
application:

1. With the 1094ARC front card pulled out of the rack or cluster­box chassis, locate the driver board on the top of the
1094ARC front card.

2. Lift the interface board gently off of the PC board.

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.

4. Re-orient the interface board into the socket with the appropri­ate interface pointed UP and with the arrow pointing toward
the front panel of the Model 1094ARC PC board.

5. Push the Interface Driver Board gently onto the socket and re­install into the rack or cluster system.

3.1.2 Connecting to a “DTE” Device

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 pur­chasing or constructing an interface cable, please refer to the pin dia­grams in Appendix C as a guide.

3.1.3 Connecting to a “DCE” Device

If the Model 1094ARC 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.

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 ori­entation of the DCE/DTE strap, as described below:

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.

3.1.5 Configuration DIP Switch Set “S1” - Management Address

Switch S1 is used to set the address of the card in the NetLink
Network Management System. When the 1094ARC is installed with a
Model 1001MC, the cards and their remote units can be SNMP man­aged using a standard Network Management Station (NMS) or a stan­dard web browser (i.e. Netscape, Internet Explorer, etc.). For more
information on setting the address, please see Appendix A of the
Model 1001MC Operations Manual.

NOTE: If you are not using your Model 1094ARC in an SNMP
managed environment, S1 switches should all be set to the ON
position.

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 set­tings of S2 are shown in the table below.

Switches S2-1, S2-2, S2-3, S2-4, S2-5: Reserved for Future Use
