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 it is the main artery cable of 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 imbalances in the cable system. They use protection maintenance by
periodically scanning the cable system electronically. By capturing minor
problems early, they can prevent major cable service disruptions later on.
