Abstract :
This paper presents the implementation of the timing, trigger and control (TTC) system of the CMS experiment currently under construction at CERN. The TTC system distributes the system clock for the experiment as well as the first level triggers and synchronization commands. The overall system is described, highlighting the differences from the original concept of the CERN RD-12 collaboration in terms of overall system architecture. Details are given of the two VME-format electronics boards that implement the necessary functionality required by the system design changes
