Abstract

The present invention relates to a system for transmitting information-carrying signals that occur as light-pulses. The system includes a signal-transmitting and/or signal-receiving central unit (1), at least one light-pulse-emitting and/or receiving device (2, 2') and at least one signal-transmitting and/or signal-receiving remote unit (3, 3') wherein the devices (2, 2') are in contact with one another through the medium of a conductor (14). Signals are transmitted between the devices (2, 2') and a remote unit (3, 3') situated in the close proximity thereof via light-pulses in free space, wherein the light-pulses are adapted to convey digital information-carrying signals structured into time frames (4, 4', 4''). Each time frame is divided into a plurality of time slots (50, 51, 52...5n) which, in turn, include a plurality of bit positions. A first type of time slot (50, 51, 52) includes information-carrying bit positions and at least one identification bit position intended for mutually distinguishing first types of time slots in a time frame, and a second type of time slot (5n) intended to synchronize the time frames. This second type of time slot differs unequivocally from the first type of time slots, partly because it lacks the identification bit position/bit positions. The sum of the number of bit positions in the time slots (50, 51, 52...5n) of the first and the second type corresponds to the number of bit positions in a time frame (4).
