Embodiments described herein may relate to power-line communication (PLC) systems that are suitable for high-voltage and electrically noisy applications. In one example system, PLC technology is used to carry data on at least one pair of conductors of a high-voltage (e.g., kilovolt) transmission line that is simultaneously used for power transmission. Further, in some instances, the transmission line may be part of a tether that connects an aerial vehicle to a ground station.

A cable assembly configured to electrically connect an active loudspeaker to a source device that comprises a source of electrical power and audio signals. The cable assembly includes a primary sheath, a group of power conductors within the primary sheath and configured to carry electrical power, a group of audio signal conductors within the primary sheath and configured to carry audio signals, a cable-mount connector male plug comprising a first plurality of power pins that terminate a first end of each power conductor and a second plurality of audio signal pins that terminate a first end of each audio signal conductor, wherein the cable-mount connector plug is configured to be coupled to a panel mount connector female socket of the source device, and a cable-mount connector female socket comprising a first plurality of power receptacles that terminate a second end of each power conductor and a second plurality of audio signal receptacles that terminate a second end of each audio signal conductor, wherein the cable-mount connector socket is configured to be coupled to a panel mount connector male plug of the active loudspeaker.

The method is used for transmitting signals and data within at least one first and one second transmission phase (TP1, TP2), which follow one another synchronously or asynchronously, between a first communication unit (L) and at least one second communication unit (Z), which comprises a central processor unit (CPU), a memory unit (M), in which an operating program (OP) is stored, and at least one first event generator (EG1), which monitors signal sequences (SL, SZ) transmitted via a transmission line (W) between the two communication units (L, Z) independently of the central processor unit (CPU) and generates event notifications (e1, e2) for events during the data transmission, which occur in accordance with the applied transmission protocol, which event notifications are transmitted to the central processor unit (CPU) and/or to at least one event user (EU1).
