Patton Electronics warrants all Model 1094A components to be
free from defects, and will—at our option—repair or replace the prod­uct should it fail within one year from the first date of shipment.

This warranty is limited to defects in workmanship or materials,
and does not cover customer damage, abuse or unauthorized modifi­cation. If this product fails or does not perform as warranted, your sole
recourse shall be repair or replacement as described above. Under no
condition shall Patton Electronics be liable for any damages incurred
by the use of this product. These damages include, but are not limited
to, the following: lost profits, lost savings and incidental or consequen­tial damages arising from the use of or inability to use this product.
Patton Electronics specifically disclaims all other warranties,
expressed or implied, and the installation or use of this product shall
be deemed an acceptance of these terms by the user.

1.1 RADIO AND TV INTERFERENCE

The Model 1094A 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 1094A 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 1094A 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).

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
(EU). A Certificate of Compliance is available by contacting Technical
Support.

2.2 DESCRIPTION
The Patton Electronics

NetLinkTMHDSL

Multi-Rate DSL Modem
provides high speed 2-wire connectivity to ISPs, PTTs, and corpora­tions using HDSL (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 to1.168 Mbps, the NetLink provides “megabyte” speeds to
leased line, LAN to LAN interconnection, and WAN access networks
over 2.9 miles/4.7km (1.152Mbps on 24AWG/.5mm wire).

The

NetLink

TM

HDSL

standalone allows DTE speeds from
64kbps to 1.152Mbps in increments of 64kbps. Features include loop­back diagnostics, inband SNMP/HTTP remote management capabili­ties and externally accessible configuration switches. A high density
2U-high rack card version of the

NetLink

TM

HDSL

is also available.

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. Featuring replaceable DCE-DTE interface
modules, the NetLink HDSL can be configured for a huge range of
V.24/RS-232, V.35, RS-422/530, G.703 and X.21 applications. Line
connection is made by an RJ-45 jack. The standard Model 1094A is
powered by a 100/230VAC(Universal) supply. The DC power supply
option supports any DC input between 40-60VDC.

IMPORTANT: The Model 1094A is equipped with flash

upgrade. Please refer to Patton website, http://www.patton.com
or contact Technical Support for the latest version of the soft­ware.

NOTE: Packages received without an RMA number will not be

accepted.

The Model 1094A is equipped with three sets of eight DIP switch­es, which allow configuration of the unit for a wide variety of applica­tions. This section describes switch locations and explains all possible
configurations.

3.1 CONFIGURING THE HARDWARE DIP SWITCHES

The 24 external switches are grouped into three eight-switch sets,
and are externally accessible from the underside of the Model 1094A
(See Figure 1).

The three sets of DIP switches on the underside of the Model
1094A will be referred to as S1, S2, and S3. As Figure 2 shows, the
orientation of all DIP switches is the same with respect to “ON” and
“OFF” positions.

Once the Model 1094A is properly configured, it is ready to con­nect to the twisted pair interface, to the serial port, and to the power
source. This section tells you how to make these connections.

4.1 CONNECTING THE TWISTED PAIR INTERFACE

The Model 1094A supports communication between two DTE
devices at distances to 4 miles (8 km) over 24 AWG (.5mm) twisted
pair wire. There are two essential requirements for installing the Model
1094A:

1. These units work in pairs. Both units at the end of the twisted
pair must have the same 2-Wire connection and DTE rate.

2. To function properly, the Model 1094A needs one

twisted pair of metallic wire. This twisted pair must be
unconditioned, dry, metallic wire, between 19 (.9mm) and 26

AWG (.4mm) (the higher number gauges will limit distance).
Standard dial-up telephone circuits, or leased circuits that run
through signal equalization equipment, or standard, flat modu­lar telephone type cable, are

not acceptable

.

The RJ-45 connector on the Model 1094A’s twisted pair interface is
polarity insensitive and is wired for a two-wire interface. The signal/pin
relationships are shown in Figure 3 below.

NOTE: Based upon the chosen DTE rate, the Model 1094A

will automatically select the optimum line rate for distance. This
selection is based on the lowest line rate that will support the
DTE rate.

IMPORTANT!: The Model 1094A has been optimized for

performance at high bitrates (DTE rates greater than 512 kbps).
To ensure accurate performance at these bit rates, please use
twisted pair line interface cable that is at least 330ft (100m) in
length.
