7.
Assume that a technical controller is preparing to interconnect two
VF circuits.
The facilities he is preparing to join must be
compatible with signal characteristics, to include
a.
polarity, bandwidth, and levels.
b.
levels, information content, and polarity.
c.
bandwidth, levels, and information contents.
d.
information contents, polarity, and bandwidth.
8.
The most important factors to consider about compatibility of
terminals when interconnecting multichannel communication systems are
a.
channel matching and equipment types.
b.
signal characteristics and channel matching.
c.
equipment circuitry and signal characteristics.
d.
equipment nomenclature and signal characteristics.
9.
A technical controller should accomplish most of his circuit
interfaces at the patching panels where equipment loops appear. The
advantages gained by connecting loops rather than lines are that
a.
individual channels are involved, signal compatibility is more
easily achieved, and ordinary wire pairs can be used, and jacks
are eliminated.
b.
signal compatibility is more easily achieved,
ordinary
wire
pairs can be used, and jacks are eliminated.
c.
ordinary wire pairs can be used,
jacks
are
eliminated,
and
individual channels are involved.
d.
jacks are eliminated, individual channels are
involved,
and
signal compatibility is more easily achieved.
