Lesson 1/Learning Event 4
c. Repair Service.
The technical controller is not responsible for
performing the repairs; his initial responsibility is satisfied when he
notifies the authorities and reroutes circuits to maintain service.
Equipment
specialist
repair
malfunctioning
equipment,
and
circuit
conditioners restore normality to interconnecting long lines and cables.
However, good service to the user is not measured by how quickly the
technical controller can restore service; it is measured by the number of
times service is interrupted to the users.
(1) If the technical controller maintains a tight
schedule of inservice
test, he will have first-hand knowledge of circuits
that are nearing the
limits of tolerance. By taking preventive action he
can forestall trouble
before it occurs and provide the best possible service
to the users.
(2) If the first indication of trouble is a complaint by the user, the
technical controller may have failed in his duty.
If the technical
controller performs his duties well he will know about the developing
problem before it occurs and take preventive action. However, it is to be
expected that equipment and circuit breakdowns do occur without notice, and
these incidents are not considered to be the fault of the technical
controller. His final responsibility to the user is satisfied only when the
user accepts the circuit and verifies that it meets requirements.
(3) The technical controller performs many tasks in addition to his
major duty of control. He is responsible, among other things for adequacy
and accuracy of operating records, for housekeeping in his area of work, and
for operator's maintenance of the patch cords and test equipment that he
uses. However, none of these duties are as important as the single duty of
providing reliable service to system users.
Learning Event 4.
PATCHING ARRANGEMENTS
The Defense Communication Agency has developed a standardized
arrangement for technical control facilities (188-310 concept), which most
stations in DCS follow.
However, local situations may dictate variations
from the master plan. Figure 1-2 is a simple block diagram (floor plan) of
a typical TCF showing the patching and test bays.
The VF primary patch
bays, equal level patch bays, and usually, the Quality Assurance Testing
Center (QATC) make up the VF circuit area in the TCF.
The TCF interface
equipment associated with this area is part of the TCF.
