Abstract: A radio base station (20) has an internal interface (26) connecting a radio equipment (RE) (24) and a radio equipment controller (REC) (22). The radio base station performs a pre-start-up procedure or method for the internal interface (26). The pre-start-up procedure is preformed preparatory to and/or in conjunction with a start-up procedure for the internal interface. As one of its aspects, the pre-start-up procedure involves storing one or more previously proven combinations of line bit rate and protocol as stored combination(s) for use on the internal interface. Prior to synchronization of the internal interface, the stored combination(s) are retrieved and included in a temporary available set of combinations of line bit rate and protocol. Thereafter the start-up procedure for the internal interface is initiated for the purpose of determining efficacy of the temporary available set.

Abstract: A data packet format includes an important information field in a data packet header or payload, e.g., a transport format indication field including one or more indicating the transport format for the data packet. It also includes one or more error correction bits associated with the important information field, (e.g., the transport format indication field), usable by an error correction scheme at a receiver to correct errors in the received header. An error detection field in the data packet is used at the receiver to detect such bit errors. In one example implementation, the one or more error correction bits are positioned in spare or unused bit locations in the data packet. In a further implementation, one or more unused bits in the important data field are used to carry the one or more error correction bits.

Abstract: Time-of-flight mass spectrometer with a position-sensitive detector (20) for determining energy and pulse of photodissociated ions, the detector (20-24) comprising one or a plurality of electron multipliers (21, 22) and an anode array (23) arranged behind the electron multipliers for determining the position of impringement of the ions, and the time-of-flight mass spectrometer including devices (30-33) for determining the time of flight of the ions.
