c. Technical information.
Technical information furnished by a TSO
includes the DCS technical schedule parameter code (V1, S1, N1, etc.), and
the type of operations (half-duplex, full-duplex, etc.), together with
modulation rate and signaling mode (dial, ringdown, etc.).
The TSO also
identifies the facilities to be used, including equipment, trunk, and
channel information.
The TSO further states outgoing and incoming test
levels, traffic or operating signal level in relation to the test tone level
(for example -18 dBm0), and it directs the testing procedures to be used in
accordance with DCAC 310-70-1. Related information is also included, such
as special AUTODIN, AUTOVON, or AUTOSEVOCOM technical data.
3-5. Quality Control.
a. Quality control tests. Quality control is a very important part of
the duties performed by technical controllers and circuit conditioners.
Tests are performed on a routine schedule, some daily, some weekly, still
others monthly or quarterly. Results of these routine tests are made part
of the circuit history file. Notice that some of the tests can be performed
while the circuit is in service, while others require the circuit to be
removed from service. Coordination among technical controllers is essential
in maintaining an unbroken flow of traffic during test periods. Technical
controllers usually schedule the test during periods of lightest traffic
flow. If a circuit carries a continuous flow of traffic, or if it carries
high-priority traffic, the technical controllers arrange to substitute other
facilities during the test period.
Table I lists the various tests and
their frequency.
