An O&M Engineer maintains telecom network sites, keeping base stations, power, batteries and cooling running through preventive and corrective maintenance. They keep assigned sites up, run preventive maintenance on schedule, restore faults fast, manage power backup and keep site safety and records in order.

What is preventive maintenance at a telecom site?

Preventive maintenance is planned upkeep done on a schedule to stop faults before they happen: checking and servicing power, batteries, cooling, earthing and equipment.
