Sumario:<HTML> <HEAD> <h2>Abstract</h2> </HEAD> <P> <BODY> <P> This document describes the protocol between the ALICE central trigger and each ALICE sub-detector. The protocol is the same for all sub-detectors and consists of a series of signals indicating trigger levels, sent by the central trigger, to which the sub-detector responds by sending a BUSY, which indicates that it is not ready to accept further new triggers. A generic block diagram of the sub-detector front-end electronics shows all the necessary stages of event buffering. The sub-detector groups are urged to study carefully the implications of the transfer rates and the chosen capacity of the multi-event buffers on the sub-detector dead time. </BODY> </HTML>
