4.
The most serious effect caused by improperly
connecting
two
communication systems is the introduction of
a.
loss.
b.
inversion.
c.
d.
distortion.
5.
Technical controllers routinely interconnect communication systems as
part of their duties. To effectively perform these duties they must
at least know the characteristics of the
a.
transmission medium, signals to be transferred, and terminating
devices.
b.
signals
to
be
transferred,
terminating
devices,
and
patching
cords.
c.
reproducing devices, patching cords, and jacks.
d.
patching cords, jacks, and transmission medium.
6.
Assume that a technical controller is preparing to interconnect two
teletypewriter communication systems.
He must assure himself that
both systems include teletypewriter which
a.
use current flow in the same direction, operate at the same
transmission speed and have similar printing mechanisms.
b.
operate at the same transmission speed, have similar printing
mechanisms, and are equipped with transmitter distributors.
c.
have similar printing mechanisms, are equipped with transmitter
distributors, and accept similar types of signals.
d.
accept similar types of signals, use current flow in the same
direction, and operate at the same transmission speed.
