Patton Electronics warrants all Model 1186 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 1186 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 1186 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 1186 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

Model 1186 offers the ability to extend E1
(G.703/G.704) service over Multi-Mode fiber. A pair of 1186 Multi-Mode
Fiber Modems provides G.703/G.704 Network "extension" between remote
locations (Figure 1).

The Model 1186 is designed to transmit/receive G.703/G.704 data
over one string of fiber. The Model 1186 allows transmission over Multi­Mode fiber with distances up to 2.5 km (1.5 miles). The clocking options for
the Model 1186 include Internal, Network (from G.703/G.704 Network) or
Receive Recovered clock (from fiber line).

The Model 1186 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 1186 is available with an AC or DC
power supply and is supported by a wide range of applications and power
supply environments.

The Model 1186 is equipped with eight DIP switches, which allow
configuration of the unit for a wide variety of applications. This section
describes the switch location and explains all possible configurations.

3.1 CONFIGURE THE HARDWARE DIP SWITCHES

The 8 external dip switches are accessible from the underside of
the Model 1186 (See Figure 2, below).

Figure 3 shows the orientation of the DIP switches in the “ON” and
“OFF” positions.

3.1.1 Configuration of Model 1186

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 1186.

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 Not Used 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 1186 units are intended to work in pairs. When setting
the clock modes for the Model 1186 units, one end of the link must be set
for Receive Recover and the other end must be set for either Internal or
Network.
