Abstract

This invention offers a vastly improved protocol to monitor and diagnose faults, in a real time fashion, within the local area network that supports Smart Repeater trunked systems. By having all repeaters take turns in broadcasting their status, between adjacent Word Frame Interrupt synchronization pulses, every repeater in the network is kept abreast of problems as they occur. The protocol can handle broken cables as well as malfunc- tioning repeaters. With this invention, whenever a net- work fault occurs, all active. repeaters know instantly (within 23.3 m ) h s t e nature of the fault, its location, and the IDS of other repeaters that can be communicated to.
