The invention relates to a communication system with at least two communication nodes for the transmission of information via a common transmission medium in a time division multiplex process. During the system start, at least one node is provided for monitoring whether a first signal which utilizes at least one slot in a regular manner is already present in the transmission medium. If a first signal is present, said node is designed for testing this first signal as to its integrity and said node is designed for sending a second signal in the case of an incorrect integrity of the first signal, and a programmable position within the time frame given by the second signal is allocated to the time slot utilized by the first signal. |
