Circuit planners in the DCA normally designate the parameters at the
time that the
a. circuits are initially activated.
b. technical controller patches the circuits.
c. subscriber requests a particular type of service.
d. circuit ends are terminated in corresponding equipment items.
9.
The DCA lists several circuit parameters in defining voice circuit
requirements. The most important circuit parameter listed is the
a. insertion loss characteristic.
b. envelope-delay distortion.
d. noise level.
SITUATION
Circuit parameters are listed in tables given in the 300-175-9
Extracts. To be a successful circuit conditioner you must be familiar with
them and be aware of their significance.
Exercises 10 through 16 are based on this situation.
10.
Three services that use circuit parameter code VI (tables 1 and 5) are
a. 066-063 IBM, facsimile, and nonsecure voice.
b. facsimile, nonsecure voice, and voice-grade AUTOVON.
c. voice-grade AUTOVON, voice-grade interswitch, and 066-063 IBM.
d. nonsecure
voice, voice-grade AUTOVON
and
voice-grade
interswitch
trunks.
