Patton Electronics warrants all Model 2073 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 2073 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 2073 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 2073 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.

22..00 GGEENNEERRAALL IINNFFOORRMMAATTIIOONN

Thank you for your purchase of this Patton Electronics product.
This product has been thoroughly inspected and tested and is warrant­ed for One Year parts and labor. If any questions or problems arise
during installation or use of this product, please do not hesitate to con­tact Patton Electronics Technical Support at [phone].

2.1 FEATURES

• Bi-directionally converts V.24, X.21,V.35 or 10 BaseT to co-direc­tional G.703

• LED indicators monitor Test Mode and Synchronization

• Internal, external or network clocking options

• Test Mode controlled by switch or by local DTE (V.24 and V.35
Versions Only)

• Complies with CCITT/ITU G.823 Jitter Control Specifications

• Built-in surge protection and transfor mer isolation

• Point-to-Point distance up to 5250 ft (1600m) on 24 AWG twisted
pair

• 120 ohm (twisted pair) network termination

2.2 DESCRIPTION

The Patton Model 2073 standalone interface converter/rate

adapter allow a synchronous V.24, V.35, X.21 or ether net device to

communicate bi-directionally over the G.703 co-directional PCM net­work. Supporting internal, external DTE timing or G.703 network gen­erated timing, the Model 2073 is perfect for networking applications
that require speeds of 9600 bps to 64 kbps. The Quick-Connect style
of interchangeable interface modules for the 2073 allow var ious physi­cal and electrical interfaces to connect to the 64K synchronous G.703
network.

A 120 ohm twisted pair telephone port provides the interface for

the G.703 network. Additionally, 75 ohm terminations can be made
using the Patton Model 460 (G.703 balun).

Diagnostics include Local Loopback and G.703 Loopback testing.

Synchronous clock jitter is attenuated in accordance with the G.823
specification.

33..00 CCOONNFFIIGGUURRAATTIIOONN

The Model 2073 is equipped with two 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 16 external switches are grouped into two eight-switch sets,
and are externally accessible from the underside of the Model 2073.

The two sets of DIP switches on the underside of the Model 2073
will be referred to as S1 and S2. As Figure 2 shows, the orientation of
all DIP switches is the same with respect to “ON” and “OFF” positions.

3.1.1 Configuration DIP Switch Set “S1”

Switches S1-1 thru S1-4: DTE Data Rates

The DTE synchronous and asynchronous data are determined by
the combined switch settings of S1-1,S1-2,S1-3, and S1-4. The follow­ing table lists all the possible switch combinations and the correspon­ding DTE data rates:

NOTE1: The four data rate configuraton switches are ignored when Octet

Timing Mode is selected (S2-1 is set to the “On” position, D8=1). In Octet

Timing Mode, the data rate defaults to 128kbps.

NOTE2: Asynchronous rates are 9600, 14,400, and 19,200. To run in asynchro-

nous mode, set the 2073 for 64K synchronous to over sample the data bits.
