    4 Configuration and Operation 4.7.1 Switching Model The basic switching model assumes that at system initialization all incoming T1/E1 timeslots and all resource board output timeslots are connected up to channels on the CT bus and that these connections are never changed. This has the advantage that once the on-board CT bus drivers have been set up they are never changed so the chances of inadvertently causing CT bus conflict is minimized.
