Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Telecommunications Equipment Installers and Repairers, Except Line Installers

ITR experience isolating communications equipment malfunctions, repairing cables and components, and calibrating equipment directly supports telecommunications maintenance.

How to prepare: Complete a hands-on commercial telecommunications equipment lab that covers circuit fault isolation and post-repair testing against specifications.

What the civilian work involves
  • Test circuits and components of malfunctioning telecommunications equipment to isolate sources of malfunctions, using test meters, circuit diagrams, polarity probes, and other hand tools.
  • Test repaired, newly installed, or updated equipment to ensure that it functions properly and conforms to specifications, using test equipment and observation.
  • Assemble and install communication equipment such as data and telephone communication lines, wiring, switching equipment, wiring frames, power apparatus, computer systems, and networks.
Civilian tools and software (examples)
  • Cisco IOS
