Lesson 1/Learning Event 2
b. Substituting
Equipment.
When
equipment
failure
occurs
on
operational circuits, technical control personnel must make equipment
substitutions after removing defective items from service. Generally, user
service can be restored more rapidly by equipment substitution than by
attempting immediate repairs on faulty equipment.
Equipment substitution
also provides the opportunity for effecting any maintenance, schedule or
unscheduled, that might otherwise be impractical because of operational
requirements.
c. Circuit Routing.
During extended outages, individual circuits are
restored by rerouting the circuits over other facilities in accordance with
their restoration priority.
Every circuit is assigned a restoration
priority in accordance with DCS policy.
To assist personnel at the
technical control facility in visualizing the possible reroute paths
available, records must be available to them for immediate reference. These
records include circuit data cards, block diagrams, and circuit restoration
plans. Such records are designed to show trunks between connected stations
and appropriate extensions that would permit a reroute to be made.
d. Circuit Activations.
The technical controller activates circuits
upon order of the Defense Communications Agency (DCA) to satisfy
requirements of the military departments (and other government agencies).
It is the responsibility of the technical controller to carry out the orders
of the DCA and to insure that all units involved in the activation do their
part. If other units do not complete their portion of the required work,
the technical controller must see that the matter is brought to the
attention of higher authority.
In like manner the technical controller
deactivates and rearranges circuits, as directed by DCA.
As a follow up
action, each technical controller must make certain that the records are
modified to reflect the latest changes.
