Communications equipment mechanics set up and maintain equipment that transmits signals to carry information.

Communications equipment mechanics do many tasks, often depending on their specialization and where they work. The following are specific types of mechanics.

Central office technicians

Central office technicians set up and maintain switches, cables, and other equipment. They work in central offices of telephone networks and Internet connections. New switches are self-monitoring and they alert repairers to malfunctions. Some switches allow repairers to diagnose and fix central office problems from a remote location.

PBX installers and repairers

PBX installers set up private branch exchange (PBX) switchboards. PBXs relay incoming, outgoing, and interoffice calls.

Installers set up equipment and connect it to power lines. They install frames and supports. They also install power systems, alarms, and phone sets. They test the connections to be sure there is enough power. They run tests to verify that the new equipment works properly.

PBX repairers figure out if the problem is in the PBX system or in the phone lines. They use small hand tools such as pliers or screwdrivers to fix equipment. They replace defective components such as fuses or wiring.

Radio mechanics

Radio mechanics install and maintain equipment that transmits and receives radio waves. Equipment is either on radio towers or in mobile units. Mechanics check equipment for faulty components or loose or broken wires. They use hand tools and electrical measuring devices to test radio functions.

Station installers and repairers

Station installers and repairers work at customers' homes or businesses. They install phone, Internet, and cable television services. They often set up modems and other computer hardware and software.

Repairers test customers' lines if there is a problem. If repair work is in the outside service lines, repairers request help from the service center.
