Civilian Career Paths

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

Maintaining IVCS PBX switches, voice terminals, media processors, and power equipment while isolating faults through testing directly overlaps with telecommunications equipment repair.

How to prepare: Complete hands-on training on a civilian PBX platform, practicing configuration, fault isolation, and post-repair testing.

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)
