The trigger and data acquisition systems in the ALICE experiment have undergone significant changes in the last year. Thisis (i) in response to the incorporation of new detectors, (ii) the result of the use of front-end buffering schemes in theALICE sub-detectors and (iii) because of new more pessimistic estimates of the data volume generated by the TimeProjection Chamber (TPC). In this report, we review the specification for the updated ALICE CentralTrigger and examinehow it might be implemented using currently available electronics components. The User Requirement Document and theTechnical Specification for this system are being discussed by the ALICE collaboration.(Abstract only available, full text to follow
