{ DFE - Digital Front-End Boards } { Collector Boards (OCTANT)} { L1 boards }
Block diagram of the CTT system from the DFE boards to the triggers. The larger rectangular boxes are all DFE mother boards. This same board is used throughout the digital FE and the broadcaster. In each of its various uses it is teamed up with either of two types of daughter boards or three types of transition modules (plugged in behind the back plane).
