Telecommunications Technician Job Description

What Does a Telecommunications Technician Do?

Above the ceiling tiles of offices and hospitals, telecommunications technicians pull and label the copper and fiber cable that carries phone calls, alarms and video links. They also install and program VoIP (internet phone) systems, test each circuit and restore service when a line goes down, for universities, hospitals, phone carriers and large employers. Emergency phones depend on that work.

Also known as: Principal Telecommunications Technician, Senior Telecommunications Technician

Telecommunications Technician Duties and Responsibilities

The primary responsibilities of a telecommunications technician include:

• Install and configure VoIP phones, voicemail and call routing for new users and departments.
• Pull, terminate and label copper and fiber optic cable in telecom rooms and ceilings.
• Test circuits and fiber runs with cable certifiers, toners and OTDR equipment.
• Diagnose outages and restore phone, data and wireless service with as little downtime as possible.
• Program PBX and VoIP systems for the moves, adds and changes that departments request.
• Keep records of cable paths, patch panel assignments and equipment locations current.
• Inspect emergency phones, elevator phone lines and alarm circuits on a regular schedule.
• Mount wireless access points, antennas and network switches in ceilings and equipment racks.
• Coordinate with contractors and carriers on new building wiring and service cutovers.
• Train staff to use new handsets, conference room systems and voicemail features.

Required Skills and Qualifications

To succeed as a telecommunications technician, you will need the following skills and qualifications:

• Structured cabling standards and fiber optic termination
• VoIP, PBX and basic IP networking
• Cable certifiers, multimeters and OTDR testers
• BICSI or fiber optic installer certification, valued by many employers
• Comfort on ladders, in crawl spaces and in cramped equipment rooms
• Methodical fault finding under time pressure
• Accurate records of every cable run and change
• Patient, courteous service for staff whose phones are down

Education and Training

A certificate program in electronics, networking or telecommunications is the most common route, which fits the postsecondary award BLS reports as typical for the trade. Pulling cable for a contractor is another way in, with the rest learned on the job. Fiber optic and VoIP certifications strengthen an application, and senior and principal technicians go on to plan projects and lead installation crews.

Salary and Job Outlook

BLS projects employment of telecommunications equipment installers and repairers to decline about 3 percent from 2025 to 2035. Even so, the group should see roughly 11,300 openings a year as workers retire or change careers. While older phone switches are being retired, technicians who handle VoIP, fiber and wireless are more likely to find steady work.
