employing DX, loop back or other dc signaling schemes (see Figure 4).
Normal simplex leads can also be used to apply sealing current to a metallic
facility from a local source external to the module.
2.12 The fourth sealing-current/simplex-lead option is bypassed simplex-
lead signaling.
This option provides a straight-through simplex-lead
signaling path between the module's facility and terminal sides that is
completely separate from the modules' transmit and receive transmission
paths. A switch option available when bypassed simplex-lead signaling is
selected provides either a normal straight-through signaling path (RCV IN
SX to RCV OUT SX and XMT IN SX to XMT OUT SX) or a reversed
straight-through signaling path (RCV IN SX to XMT IN SX and RCV OUT
SX to XMT OUT SX). The reversed signaling-path option is used to
compensate for polarity reversals in duplex- (DX-) signaling and ground-start
application.
3. INSTALLATION
Inspection
3.01 The 104001C Prescription Line Amplifier module should be visually
inspected upon arrival to find possible damage incurred during shipment. If
damage is noted, a claim should immediately be filed with the carrier. If
stored, the module should be visually inspected again prior to installation.
Mounting
3.02 The 104001C module mounts in one position of an Accurate Type-10
Mounting Shelf, which is available in configurations for relay-rack and
apparatus-case installation, or in one position of an Accurate 246 Resistive
Data Bridge Mounting Assembly.
electrically into a 56-pin connector at the rear of its shelf or assembly
position.
Installer Connections
3.03 Before making any connections to the mounting shelf or assembly,
ensure that power is off and modules are removed. Modules should be put
into place only after they are properly optioned and after wiring is completed.
When installing 104001C modules in 246 Assemblies, refer to the Accurate
practice on the 246 Resistive Data Bridge System for cabling instructions and
module pinout assignments.
3.04 Table 3 lists external connections to the 104001C module. All
connections are made via wire wrapping to the 56-pin connector at the rear
of the module's mounting shelf position. Pin numbers are found on the body
of the connector.

Strap Options
3.05 As shipped from Accurate, connector pin 43 is the 104001C's XMT
OUT SX lead and connector pin 3 is the RCV OUT SX lead. If an additional
(or alternative) connector-pin appearance for the XMT OUT SX lead is
desired on pin 45, install option strap JP9 where indicated on the module's
printed circuit board, as shown in Figure 6. If an additional (or alternative)
connector-pin appearance for the RCV OUT SX lead is desired on pin 1,
install option strap JP10 where indicated on the module's printed circuit
board (also shown in Figure 6). Before installing JP9 or JP10, be sure to
observe the caution below.
Switch Options
3.06 Five option switches must be set before the 104001C can be placed into
service. Locations of these switches on the module's printed circuit board
are shown in Figure 6, and instructions for setting the switches are given in
paragraphs 3.07 and 3.08.
FIGURE 6. 104001C Option Switch and Strap Locations.
CAUTION: Extreme care must be taken when soldering on printed circuit
boards to prevent damage to the delicate foil. Use a soldering iron with a
tip temperature of 800 degrees or less. Use only 60/40 or 63/37 tin / lead
rosin-core solder. Do not hold the tip of a hot iron on a soldering
connection for longer than two (2) seconds.
Note: All switches on the front panel of the 104001C are used for
alignment and are covered in paragraph 3.09 through 3.014.
Terminating Impedances
3.07 Switch S1 selects the terminating impedances at the 104001C's facility-
side ports (rcv in and xmt out). Switch S3 performs the same function for the
4001's terminal-side ports (rcv out and xmt in). Set each switch to the 1200,
600, or 150 position as required. In general, 1200-ohm impedance is used to
interface loaded cable, 600-ohm impedance is used to interface non-loaded
cable, carrier, SF or DX signaling units, terminating sets, or station apparatus,
and 150-ohm impedance is used to provide a small amount of slope
equalization through the deliberate impedance mismatch when the module
interfaces long section of non-loaded cable (see paragraph 2.07)
Facility-Side Sealing-Current/SX-Lead Options
3.08 Switch S6 conditions the 104001C to supply internally generated 25mA
sealing current, to accept externally supplied sealing current from the distant
end of the facility, or to derive normal simplex leads on the facility side.
Select the desired facility-side sealing current/SX-lead arrangement as
follows:
For normal SX-lead derivation on the facility-side, set S6 to SX.
For internally generated 25mA sealing current on the facility
side, set S6 to SOURCE.
