Abstract: The invention relates to a method for detecting errors in communication connections having a plurality of physical connections (V1-V3) between two stations (BS or BSC). Data divided between at least two bundled physical connections (V1-V3) is transmitted, the individual connections being respectively monitored in the stations (BS or BSC) for errors. In the event of a connection error, the defective connection (V1) is deactivated. The aim of the invention is to enable an individual connection to be deactivated without large signalling costs and delays. To this end, the deactivation is autonomously carried out in relation to the two stations (BS or BSC), independently from each other and independently from other system devices.

Abstract: A base station for a radio communications systems contains at least one carrier-related transceiver device and at least one central unit for controlling the base station. The transceiver device and the central unit each contain at least one interface device which are connected by at least one individual line in accordance with a point-to-point connection for transmitting traffic data. Therefore, point-to-point connections with individual lines for each transceiver device that do not need to satisfy the requirements of identical lengths are used instead of a bus structure. In this way, an essentially more cost-effective implementation of the transmission of traffic data between the central unit and transceiver device is possible because the data rate can also be increased in accordance with the length of the individual line. A logic bus structure is mapped onto physical point-to-point connections. Traffic data, o&m data and also synchronization data are transmitted using the bus structure.

Abstract: During the transmission of signals using differential transmission methods a direct voltage portion of the signal is used downstream. The direct voltage portion is used on the receiver side to provide information concerning the operational state of the transmitter. To do this, a pair of serially arranged resistors may be connected in parallel with the receiver. A detector may be connected between the resistors.
