Abstract
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.
Claims9
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,
- wherein at least one node is provided for monitoring during the system start whether a first signal which utilizes at least one slot in a regular manner is already present in the transmission medium,
- wherein said node is designed, if a first signal is present, for testing this first signal as to its integrity, and
- wherein 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.
A method of starting 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,
- wherein at least one node is provided for monitoring during the system start whether a first signal which utilizes at least one slot in a regular manner is already present in the transmission medium,
- wherein said node is designed, if a first signal is present, for testing this first signal as to its integrity, and
- wherein 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.
A TDMA signal with a time frame which comprises at least one static time slot and at least one dynamic time slot, wherein a spare time slot is provided within the time frame which is reserved for accommodating an incorrect time slot.
