Telecommunications Equipment Installers and Repairers, also referred to as telecom technicians either install and maintain or disconnect devices that transmit communications signals. Communication signals include Internet routers, telephone lines, and other such equipment. The installers undertake these tasks in homes, offices, and other sites that are in the construction stages. They may also install communications wiring and equipment of communication in these locations.

Technicians utilize various tools to scrutinize equipment and assess problems. They use polarity probes and spectrum analyzers to trace distortions in signals, while hand tools, such as screwdrivers and pliers, are used to repair equipment.

There are different types of installers and repairers, such as central office technicians, home installers and repairers, and headend technicians.

Central office technicians install and maintain routers, fiber-optic cables, switches, and other such equipment at switching centers, which are called central offices. From several Internet, telephone, and cable connections in these centers, data is disseminated, processed, and enhanced. Auto monitoring switches send alerts to technicians concerning equipment failure. They then have to rectify these issues remotely.

Although headend technicians work on similar tasks, their work arrives from distribution centers of cable and television companies, known as headends. They maintain and repair signals for cable networks. 

Meanwhile, home installers and repairers establish and fix telecom equipment in homes of clients at their business premises. Their tasks include setting up the phone, cable television, and Internet services.

They resolve problems at homes or offices by finding out if issues exist within buildings. If they are found within the premises, technicians resolve them. In case problems exist outside, technicians refer them to line repairers to fix them.

While some technicians operate installation and repair services within homes, others work in service centers or offices. As they may need to work at heights like roofs and top storeys, they need to climb ladders and poles.

Technicians may, at times, work in severe conditions, as the positions are constricted and uncomfortable. They may need to crouch, stoop or crawl. Technicians also may have to lift heavy contraptions enter cable vaults and manholes to set up, maintain or examine equipment.

They have to work flexible hours and so have to be available round-the-clock. Technicians need to have excellent analytical and problem-solving skills.
