Lesson 2/Learning Event 1
LESSON 2
CONCEPTS OF CIRCUIT CONDITIONING
TASK:
Describe the duties of technical controller, determine
circuit parameters using the Defense Communication System
(DCS) technical schedule, and if VF circuits meet selected
parameters.
CONDITIONS:
Given
information
about
the
duties
of
a
technical
controller, description of DCS technical schedule, and an
extract from DCAC 300-175-9 of a DCS Technical Schedule.
STANDARDS:
Demonstrate competency of the task skills and knowledge by
responding to the multiple-choice practice exercise; select
the ONE answer that BEST completes the statement or answers
the question, covering concepts of circuit conditioning.
(This objective supports Tasks 113-616-3018, Test Circuit for Impulse Noise,
TD-8; 113-616-3020, Test Circuit for Composite Data Transmission Level, TD-
10; 113-616-3062, Determine Test Tone Level; 113-616-3075, Test Circuit for
Basic Noise, TD-6; 113-616-3031, Perform In-Service QC Tests.)

Learning Event 1: THE THREE A'S OF CIRCUIT CONDITIONING.
The duties of a technical controller include three interrelated
operations: Analyze, apply and adjust.
Although the duties involved with
circuit activations affect the circuit conditioner, responsibility for
activation rest with the technical controller.
a. Analyze.
Using testing devices, the circuit conditioner must be
able to analyze new circuits prior to activation, and to analyze existing
circuits for troubles when called upon to do so. Further, he must analyze
telephone circuits to determine whether they can be conditioned to satisfy
the needs for expanded high-speed service.
b. Apply. The circuit conditioner must be able to determine the need
for correction, using specified test equipment items. Further, he must be
able to select the corrective items needed to achieve the circuit
requirements. He must also be able to apply circuit data furnished by the
DCA.
