Routine upkeep and cleaning of the communication appliances devices is as important as periodic inspections of connectors, updates of software and firmware, as well as conducting various tests including, power supply and transceiver checks. Problems can be addressed proactively with preventative maintenance that is performed during quarterly or annual checkups. Predictive maintenance is aided by remote performance monitoring systems that track defined KPIs. When integrated with remote systems, parts retrieval systems streamline ordering and reduce operational lag, enabling preemptive maintenance.
