Assume that you are visiting a technical control facility and observe
a large number of patch cords being used. This indicates that the
traffic load is very heavy.
normal-through feature is being used.
technical control center is operating in a normal manner.
operator is experiencing equipment or circuit difficulties.
Group patch panels are usually located between the multiplex terminal
output and the input of the wideband radio terminal.
panels use coaxial cable connectors rather than the normal patch cords
baseband frequencies extend into the lower radio frequency range.
connections must be frequently disconnected by the radio terminal
radio terminal is usually
power output of the multiplexer
capability of normal patch cords.
Four types of test instruments which can be found in most technical
control facilities include a decibel meter, DC milliammeter, signal
generator, and harmonic analyzer.
Three basic test instruments used
by the technical controller for routine operations are the
signal generator, DC milliammeter, and dB meter.
DC milliammeter, VU indicator, and harmonic analyzer.
