The TFC Switch 'THOR' is a programmable
patch panel located in the TTC distribution network which allows
associating sub-systems to different ODINs. The sub-systems may thus be
configured to sustain completely different timing, triggering, and
control, and can also be connected to local trigger sources. The THOR
distributes in parallel the information from the Readout Supervisors to
the Front-End electronics of the different sub-systems.
