What telecom and field service teams do
Field technicians and engineers install new connections or equipment, attend breakdown calls, carry out preventive maintenance visits and close each job card with photos and customer sign-off. In telecom networks, O&M engineers keep tower sites, fibre routes and exchanges running, with rapid response teams for fibre cuts and site outages. A network operations team monitors alarms and dispatches field staff. Service coordinators assign tickets, track service levels and chase spare parts. Supervisors check work quality, train new technicians and handle escalations from key customers. Spares teams issue parts against tickets, and safety staff manage work at height and electrical safety for tower and site work.
Field teams at 50, 500 and 5,000 employees
A 50-person service company, such as a CCTV, broadband or AC service provider in one city, usually has a service manager, a coordinator who takes calls and assigns jobs on WhatsApp, and technicians and helpers who travel by two-wheeler across the city. With about 500 employees, the company covers several cities with a service head, city or area service managers, supervisors, technicians grouped by product or network, a call desk and a spares store in each city.
At 5,000 employees, typical of a telecom infrastructure or national field service company, the business is organized by circle or region, each with a circle head, cluster managers, O&M managers, field engineers and technicians, supported by a central network operations team that works round the clock. Specialist teams handle fibre rollouts, tower installation and enterprise customers, and many technicians work in shifts or stay on call for outages at night.
How field teams work with the network desk, stores and HR
The network operations or service desk decides where each technician goes next, so field teams and the desk must agree on travel time, priority rules and when a job can be closed. Stores must keep the right spares at the right hub, or first-time fix rates fall. Sales hands over new installations with complete customer details. Finance handles travel allowances, fuel reimbursement and vendor bills for subcontracted work. HR manages field attendance, on-call and night allowances, safety training certificates, and the transfers that come with network expansion. Mobile app punches that record GPS location suit technicians who start the day at a customer site instead of an office.
Job approvals and reporting lines
Technicians report to a supervisor or team leader, who reports to an area or cluster service manager, then the circle or regional head and the head of service or operations, who reports to the COO. Job completion is approved by the supervisor after checking the job card and photos, and repeat complaints within a set period go back to the supervisor for review. Spare parts above a set value, for example ₹20,000, need the area manager's approval, and subcontractor bills are certified by the cluster manager. Leave and weekly offs are approved by the supervisor so each territory keeps enough technicians on duty, and HR records them.

What is the hierarchy in a telecom field team?
Field technicians and helpers sit at the base of a telecom team, with senior technicians, O&M supervisors or team leaders, O&M or cluster managers, the circle operations head and the head of network operations above them. Network operations desk engineers, planners and spares staff support the field line and report to their own managers.
What does a field service engineer do?
A field service engineer installs, maintains and repairs equipment at customer sites or network locations. They receive jobs from the service desk, travel to the site, diagnose faults, replace parts, test the system, update the job card with photos and customer sign-off, and report recurring problems. They also carry out preventive maintenance visits on a schedule.
How do field service companies track technician attendance?
Technicians often start the day at a customer site, so companies use mobile app punches with GPS location at the first and last job, alongside job cards that show where they worked. In ZeniaHR, a company can restrict punches to its approved check-in spots and to each technician's approved phone, and supervisors approve missed punch corrections before HR.
Do telecom technicians work night shifts?
Many do. Network operations desks run around the clock, and rapid response teams for fibre cuts and site outages work in shifts or on call at night, while installation and preventive maintenance usually happen by day. Companies pay night or on-call allowances as per their policy, and hours beyond the normal working day count as overtime at double the ordinary rate.
