Additional Information

Other Essential Skills:

Working with Others

Telecommunications installation and repair workers typically work alone and beside other technicians doing similar tasks at work sites and service centres. Some workers, in particular those at switching centres and those who are involved in large‑scale installations, may work with partners to improve efficiency. They share information in a timely manner with co‑workers, including dispatchers, customer support staff, analysts, salespeople and supervisors, to provide telecommunication services to a wide range of customers. For example, they may review operation guidelines for telephone equipment with co‑workers or coordinate efforts to troubleshoot equipment and system faults.

Continuous Learning

Telecommunications installation and repair workers need to keep pace with the rapidly evolving technological and regulatory environment in their field. Most often, their learning objectives are set by their managers and supervisors. They learn informally by exchanging information with co‑workers during work hours and by reading information provided in bulletins and manuals. Often, their employers require them to attend and pass courses for new equipment and customer service. They may take courses on their own initiative on topics such as two‑way radios and optical data transmission systems.

Impact of Digital Technology

All essential skills are affected by the introduction of technology in the workplace. Telecommunication installation and repair workers’ ability to adapt to new technologies is strongly related to their skill levels across the essential skills, including reading, writing, thinking and communication skills. Technologies are transforming the ways in which workers obtain, process and communicate information, and the types of skills needed to perform in their jobs. In particular, telecommunication installation and repair workers require advanced digital skills to diagnose and repair telecommunications equipment. They also must be able to operate computerized tools and equipment to perform their duties. For example, workers may use diagnostic equipment (e.g. oscilloscopes) to troubleshoot system faults, or use application‑specific measurement and diagnostic software to troubleshoot and test telecommunication systems. The requirements for digital skills will likely increase as electronic technologies continue to advance.

Technology in the workplace further affects the complexity of tasks related to the essential skills required for this occupation. For example, the sophisticated electronic circuitry used in communication equipment has increased the complexity of wiring schematics and other diagrams. On the other hand, electronic databases and keyword search functions can make it easier to find information, such as specifications. Workers can also calculate costs, material requirements, conversions, electrical resistance, volumes and rates using Web‑based applications, specialized software and hand‑held devices, such as calculators and personal digital assistants (PDAs).
