A cable system for a truck trailer with connectors having a main power connection, a ground connection, and one, two, or more communication cable connections. Connectors include at least a power and ground connection for electrically connecting an individual trailer to the cable system. A master control circuit may be included in the trailer nosebox, and the master control circuit configured to send commands to slave control circuits mounted within the connectors. The slave control circuits in the connectors are configured to receive a control command sent by the master control circuit that may include an address, mode identifiers, or other indications of which connectors in the cable system should take action, and what actions should be taken.

Air conditioning related equipment includes a communication circuit that is communicably connected via at least two of a communication line through which a communication signal is transmitted, a high-voltage power source line through which high-voltage power is transmitted, and a low-voltage power source line through which low-voltage power is transmitted.

A power line-Ethernet hybrid injector is provided. The power line-Ethernet hybrid injector includes a first power line and a second power line that each transfer power supplies with opposite polarity to each other, a plurality of branch lines branching off from the first power line and the second power line, a first communication line that transfers communication data and is provided in a number corresponding to the plurality of branch lines, a first low-frequency pass filter that allows the power supplies to pass through and blocks the communication data, a first high-frequency pass filter that blocks the power supplies and allows the communication data to pass through, and a plurality of Ethernet power line communication lines that transfer power / communication data which is a combination of the power supplies that have passed through the first low-frequency pass filter and the communication data that have passed through the first high-frequency pass filter.

For reliable, failsafe monitoring of the locking of a closure device of a vehicle of a cableway is disclosed in which provision is made for an electrical connection to be established between a vehicle powerline modem on the vehicle and a station powerline modem, which is connected to the cableway controller, via a busbar in the station, with which contact is made by a current collector of the vehicle, and for the locking status of a locking unit to be transmitted from the vehicle to the cableway controller via this connection by means of powerline communication, wherein, in the event of defective locking, the vehicle is stopped in the region of a busbar in the station and the locking status is transmitted to the cableway controller again when the vehicle is at a standstill.

Systems and methods for setting a carrier-sensing mechanism in a PLC node are disclosed. In a PLC standard, coexistence is achieved by having the nodes detect a common preamble and backing off by a Coexistence InterFrame Space (cEIFS) time period to help the node to avoid interfering with the other technologies. In one embodiment, a PHY primitive is sent from the PHY to the MAC know that there has been a preamble detection. A two-level indication may be used—one indication after receiving the preamble and other indication after decoding the entire frame. The MAC sets the carrier-sensing mechanism based on the preamble detection.
