Abstract: Electrical connectors with integral fault detection are provided. The connectors are adapted to be coupled to AC multi-phase electrical cables, and can include a plurality of phase contacts, a detector, and an indicator. The phase contacts include a first phase contact, a second phase contact, and a third phase contact to receive a first phase, a second phase, and a third phase, respectively, of the electrical cable. The detector is configured to monitor a first temperature associated with the first phase contact, a second temperature associated with the second phase contact, and a third temperature associated with the third phase contact to detect a temperature fault at any of the contacts. The indicator is operatively coupled to the detector and is configured to indicate presence of the temperature fault.

Abstract: A master repeater controls a trunked communication system having a number of communication resources. The master repeater determines (201) how many communication resources are available to the master repeater. When one control resource and one message resource are among the available communication resources (203), the master repeater suspends (211) trunked communication system operation when the number of available communication resources are less than a minimum number of resources (205), and the available communication resources fail to include all control resources (207) from the trunked communication system.
