Installation
ATTENTION
Instal lation s ho uld be performed by qua l ified service perso nnel only in
accordance w it h the Na tional Electri cal Code or applicabl e local codes.
Mounting
1. Unlock the front door of the enclosure using a screwdriver by rotating the lock a quarter turn
counterc loc kwise, and open t he front d oor, which is hinged on the l e ft.
2. Disconnect the ribbon cables and the ground wire connections from the interior rear panel. Remove
the four bolts that hold the rear panel in place, and set this assemb ly and the bolts aside in a safe
location.
3. Position the enclosure on the mounting surface. The enclosure provides four 0.50-inch mounting
holes. Secure it with four 3/8-inch diameter bolts of the appropriate lengths for the mounting surface,
flat washers and nuts. To ensure proper sealing and enclosure protection rating, use the provided
sealing washers. Install the sealing washers inside the enclosure with the tapered cone against the
enclosure and then add the flat washer s. See Figure 6 for installation details.
4. Prepare the enclosure for cable entry. For example, if conduit is installed, create an access hole using
a metal hole punch that is equivalent in size to the conduit diameter.
5. Re-install the rear panel assembly using the four bolts removed previously. Re-attach the ribbon
cab le connectors and th e grou nd wires.
6. Pull the cables into the enclosure, and make connections per the wiring section.
7. Complete the installation by closing the front door and relocking the enclosure.

Wiring
The Model LE200 provides the interfaces for customer connections described below. All of the
terminations on the PCBAs support a wire size range of No. 24 AWG to 12 AWG.

Power Con nections
WARNING
The input voltage selector switch must be in the appropriate position before
power is ap plied to the Line Extender.
The Line Extender provides a double-pole circuit breaker for the input power. This input voltage may be
set to either 115 V ac at 50/60 Hz or 230 V a c at 50/60 Hz via an input selector switch, which is located
on the +48 V Power Supply.
A ground and spare terminal block are located next to the double-pole circuit breaker. The orange wire
found in GAI-Tronics system cab l e can b e terminated at t his spare terminal.

Training the Echo Cancellation
Overview
Line echo (also known as electric or hybrid echo) is created by the electrical circuitry connected to a twowire (full duplex) audio system. Echo is inherent in all full-duplex audio systems and is affected by the
audio line length and line impedance mismatches. The presence of audible echoes results in undesirable
audio qua lity. This kind of qual ity degradati on is inhere nt in t h e netw ork equip me nt an d e nd-u ser phone
devices.
To minimize echo, the Model LE200 performs an echo cancellation training sequence on party lines 1
through 5 . The echo ca ncellatio n training tak es approxi mate ly 15 seconds and is perf ormed aut omatically
one minute after power is applied to the LE200. This delay allows all power levels to stabilize prior to
perfor mi ng ech o c ancellation tra i ning. Echo cancellat i on can be manu all y initiated as described below.
OTE: Signal impulses are transmitted onto the audio lines during the echo cancellation training
N
sequence. Handset stations that are in use on a party line will hear the signa ls in the handset receiver. For
troubleshooting purposes, the one-minute delay may be disabled by closing DIP switch SW6-1.
Manual In itiation of E cho Cancelin g
Press and release push button PB1 on the main PC board three times. The push button must be pr essed
for at lea st one quarter second and no more than two seconds each time. The timing requirement is meant
to prevent accidental requests. If an error is made with the push-button timing, the sequence must be
repeated from the beginning.
The main board LEDs will indicate the progress of the echo canceling sequence. One column of LEDs
turns on after each push button press or release until the sequence is started. Once the sequence is started,
those LED s rema in on, and a c ountd own timer is disp layed on th e rema ining L EDs. The LED s return t o
normal op eration after the echo c ancellat ion training seque nce is complete.
