Cable technicians typically start out as cable system installers. Installers prepare a subscriber's home for cable reception by connecting the cable system to one or more televisions or to one or more computers for high-speed Internet services. Installers explain to subscribers how to operate the cable system and how to update or downgrade their services. If a customer no longer wants the cable system, the installers remove it. Installers may also be responsible for maintaining the power lines that connect the main cable to small groups of houses and downpipes that are the direct lines of the cable to a subscriber's house. In general, installers do some troubleshooting if customers have minor problems with their cable assemblies.
Start-up technicians must have more advanced technical skills than installers. Start-up engineers continuously maintain the main or connecting line of the cable system. This work is very important because the external line is the main artery of a cable system and a malfunction can interrupt operation in a large area. Start-up technicians are responsible for correcting technical errors in the external line, in the power amplifier or in the booster.
Service technicians respond to problems reported by a subscriber. These technicians generally repair amplifiers, cables, or wires. You can also fix electrical errors in the cable system. They carry out preventive maintenance work by regularly scanning the cable system electronically. By identifying minor problems in advance, they can prevent serious cable failures later.
Not all cable television and telecommunications technicians work on site. The desk technicians, highly specialized electronics engineers, manage the repair structure of the cable system. They examine defective and faulty devices, repair them, record repairs and bring devices back into the field.
