The present invention relates to α method for controlling α remote unit (10) over α signal line (20), the remote unit (10) being switchable in-between the transmit mode and the receive mode. The remote unit (10) in transmit mode is used for transmission of useful information (26) which is input to the remote unit (10) over the signal line (20) and the remote unit (10) in receive mode is used for reception of useful information (26) which is output by the remote unit (10) over the signal line (20). The method comprises the following steps, providing an activation signal over the signal line (20) before the transmission of useful information (26) over the signal line (20), and detecting said activation signal (27) at the remote unit (10) and switching the remote unit (10) to transmit mode. The invention also relates to a controlling unit and a remote unit for performing said method.

The present invention relates to the field of base stations, in particular to multistandard base stations such as GSM/UMTS base stations. Furthermore, the present invention relates to a transmission method combining signals from two transmitters of such a base station. The transmission method according to the present invention combines signals from two transmitters by providing the signal of a first transmitter 3 to a band-pass filter 5, providing the signal of a second transmitter 2 to a notch filter 6, tuning the band-pass filter 5 and the notch filter 6 to the same frequency, and combining the outputs of the band-pass filter 5 and the notch filter 6.

Embodiments provide a connection box, a main box, and a base station transceiver. The connection box 10 of the base station transceiver 100 is operable for connecting a backhaul processing component of the base station transceiver 100 to a backhaul access system of a mobile communication system. The connection box 10 comprises a housing 12 for an electronic backhaul processing component of the base station transceiver 100 of the mobile communication system and means for mounting 14 a main box 20 with a front end processing component of the base station transceiver 100 of the mobile communication system. The main box 20 comprises a housing 22 for an electronic front end processing component of the base station transceiver 100 and means for attaching 24 the main box 20 to the connection box 10 with the backhaul processing component of the base station transceiver 100.
