Abstract (en)
[origin: WO9934591A1] The invention relates to a method for connecting a peripheral unit to an information transmission system. Said unit is remotely powered by a central location via a transmission line. In a first step, the peripheral unit is connected to the transmission line with a remote power voltage. In a second step, a test voltage which is smaller than the remote power voltage of the unit, said remote power voltage being provided for the operation, is applied to the central location end of the transmission line, and the connection state pertaining to the peripheral ends of the transmission line is established by a measurement of the quantity of electricity flowing in the transmission line which is conducted at the central location end. In a third step, the remote power voltage is increased on the operating remote voltage when the correct connection state of the transmission line is established.
