Wireless video service or "wireless cable." Came into existence when: -
correct answers Businesses used microwave frequencies to offer channels to
customers who could not receive more traditional cable services.
How can a distributor amplifier be identified in the network or on a network
designed map? - correct answers The distribution amplifier has multiple
downstream outputs.
What should you be looking for when analyzing the network design maps to
troubleshoot a problem? - correct answers The device common to those
customers affected before traveling to make signal status checks.
What is spliced into the hardline coaxial cable to combine the AC power with
the transported RF signal in a hybrid fiber/coax (HFC) network? - correct
answers A power inserter.
How can a less experience technician identify what a non-standard symbol on
the network design maps represent? - correct answers The legend at the
bottom of the network design map that defines the map symbols, cable, types,
and amplifier data.
, What is required for checking the physical network integrity when maintaining
the coaxial cable network? - correct answers Being observant and performing
some minor tasks while engaged in regularly scheduled activities.
What test instrument sends out a test signal and displays any reflections
caused by impedance mismatches in the cable that are characteristic of cable
faults? - correct answers Time domain reflectometer (TDR)

What is a common solution when congestion from modem activity and traffic
becomes unacceptable in a hybrid fiber/coax (HFC) network? - correct
answers Node splitting, the subdividing of serving areas into two or more
smaller serving areas.
In the tree-and-branch architecture, how is the downstream signal from the
trunk fed to the distribution branches? - correct answers Within each trunk
amplifier, a portion of the downstream is fed to a bridger amplifier to boost the
signal before being split and routed to the distribution branches.
