Cable technicians usually start out as cable system installers. Installers prepare a registrar'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 service. Installers explain to subscribers how to operate the cable system and how to upgrade or downgrade their services. If a customer no longer wants the cable system, installers will remove it. Installers can also rely on servicing feed lines, which connect the main cable to small groups of households, and droplines, which are cable lines directly to a registrar's home. Installers usually have mild problems when customers have minor problems with their cable units.
Stock technicians need to have more advanced technical skills than installers. Stock technicians maintain the main line, or main line, of the cable system on an ongoing basis. This work is very important as the main artery cable is a cable system and can seriously damage service in a large area. Stock technicians are responsible for any technical failures in the mains, feed amplifier, or upgrade.
Service technicians deal with problems reported by a registrar. These technicians usually repair amplifiers, cable poles, or lines. They can also correct electrical damage in the cable system. They use protection maintenance by periodically scanning the cable system electronically. By catching small problems early, they can prevent a major cable service disruption later on.
