1.1 RADIO AND TV INTERFERENCE
The Model 1186RC 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 1186RC 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 1186RC
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).

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

Modem
The Model 1186RC is designed to transmit/receive G.703/G.704 data
over one string of fiber. The Model 1186RC allows transmission over MultiMode fiber with distances up to 2.5 km (1.5 miles). The clocking options
for the Model 1186RC include Internal, Network (from G.703/G.704
Network) or Receive Recovered clock (from fiber line).
The Model 1186RC 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 1186RC is supplied with a
1001RCM703ST (with an ST fiber connector) or a 1001RCM703SMA (with
an SMA fiber connector) rear card.

3.0 CONFIGURATION3.0 CONFIGURATION
3.1.1 Configuration of Model 1186RC
The Model 1186RC 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 1186RC (See Figure 2, below).

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

Note: The Model 1186RC units are intended to work in pairs. When setting the clock modes for the Model 1186RC units, one end of the link
must be set for Receive Recover and the other end must be set for either
Internal or Network.
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.
