Patton Electronics warrants all Model 1193 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 1193 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 1193 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 1193 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).

WARNING: This device utilizes a class IIIB laser device which emits
invisible light. There is potential for eye damage if proper caution is not
taken. The laser port output is classified as class IIIA due to attenua­tion in the fiber cable. Eye protection should be worn at all times when
the unit is operational and the laser port is not connected. The laser
assembly should not be modified in any way. The fiber cable should
never be disconnected from the laser device for any reason. The
laser's wavelength is specified in the range of 1280 nm to 1330 nm
with a maximum power output of 800 uw. Eye protection should be
specified to handle the stated wavelength. Never look directly into to
the laser port.

1.3 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.

1.3 SERVICE

All warranty and non-warranty repairs must be returned freight
prepaid and insured to Patton Electronics. All returns must have a
Return Materials Authorization number on the outside of the shipping
container. This number may be obtained from Patton Electronics

2.2 DESCRIPTION

The Patton Electronics

Model 1193 extends E1 (G.703/G.704)
service over Single-mode fiber. A pair of 1193 Single-Mode Fiber
Modems provides G.703/G.704 network "extension" between remote
locations (See Figure 1 below).

The Model 1193 is designed to transmit/receive G.703/G.704 data
over one string of fiber. The Model 1193 allows transmission over
Single-mode fiber with distances up to 50km (31 miles). The clocking
options for the Model 1193 include Internal, Network (from
G.703/G.704 Network), or Receive Recovered clock (from fiber line).

The Model 1193 also incorporates V.54 compliant local/remote
loopbacks and V.52 compliant 511/511E test patterns. Front panel
switches activate test patterns and loopbacks. LED status indicators
monitor the fiber and G.703/G.704 links. The Model 1193 is available
with either an AC or DC power supply and is supported by a wide
range of applications and power supply environments.

The Model 1193 is equipped with eight DIP switches, which allow
configuration of the unit for a wide variety of applications. This section
describes location of the switches and explains all possible configura­tions.

3.1 CONFIGURING THE HARDWARE DIP SWITCHES

The 8 external dip switches are accessible from the underside of
the Model 1193 (See Figure 2 below).

Figure 3 shows the orientation of the DIP switches in the

“ON” and “OFF” positions.

3.1.1 Configure the Model 1193

Switches S1 through S8 may be used to configure clocking modes
and line coding. Default settings of the switches are shown in the table
below. A description of the switch options follows the table.

Switches S1 and S2: Clock Mode

Use switches S1 and S2 to determine clock mode of the 1193.

S1 S2 Setting Description

On On Internal Transmit clock generated internally

On Off Receive Recover Transmit clock derived from the line

Off On Network Transmit clock derived from G.703/G.704

equipment interface

Off Off Internal use only

Switch S3 and S4: Line Coding Options

Use switches S3 and S4 to determine whether the G.703/G.704 line
coding is HDB3 or AMI (for older telecommunications equipment). The
line coding must be the same line coding prescribed by the NAP
(Network Access Provider). Most applications will use HDB3.

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 vio-

Note: The Model 1193 units are intended to work in pairs. Set the clock
modes for the Model 1193 units with one end of the link set for receive
recover and the other end set for either internal or network.
