LESSON 3
PRACTICE EXERCISE
In each of the following exercises, select the ONE answer that BEST
completes the statement or answers the question.
Indicate your solution
by circling the letter opposite the correct answer in the subcourse
booklet.
1.
The AN/MSQ-73 is an air-transportable communications
technical
control center whose primary function is to
a.
terminate 4-kHz VF circuits.
b.
terminate DC and VF circuits.
c.
interconnect communication systems.
d.
test circuits passing through the van.
2.
Assume that you are asked to comment on a proposed operation which
calls for wideband circuits from telephone carrier terminals to be
interconnected through the AN/MSQ-73.
Your comment will state that
the maximum bandwidth of channels which can be interconnected through
the AN/MSQ-73 is
a.
1 kHz.
b.
4 kHz.
c.
20 kHz.
b.
140 kHz.
3.
Wire pairs are used to connect tactical teletypewriters to circuits
in the AN/MSQ-73. How is a wire pair connected in the van?
a.
Both wires in the pair are isolated from ground.
b.
One wire is grounded at the CDF and the other wire goes to a
patching circuit.
c.
Each wire pair and its associated teletypewriter are connected
together at the CDF, thus eliminating the need for patching.
d.
One wire of each pair connects directly to a patching panel,
eliminating the need for wiring at the CDF.
