How does a grade crossing supervised circuit work?
A grade crossing supervised circuit operates by using sensors to detect the presence of trains approaching the crossing. When a train is detected, the system activates warning signals, such as flashing lights and gates, to alert motorists and pedestrians of the oncoming train. The circuit continuously monitors the crossing area, ensuring that the warning signals remain active until the train has cleared the crossing. This system enhances safety by preventing accidents at railway crossings.

What is the functions of utp crossover cable?
The crossover cable switches the signals between one end of the cable to the other. This causes the transmit signal on one end to be the receive signal on the other end.The reason for crossing over is to allow a transmitting system to send signals to a receiving system. Without crossing over the signals a transmit signal would arrive at a transmit signal, which is equivalent to a person talking to another person without ever listening (i.e. it won't work for a conversation).
