shows an example of a DV-33512 router with a pair of pro-
tected paths.(Depending on system requirements, the upstream splitter
may or may not be needed.) The signal detector monitors the primary
path and if necessary will disable the primary path output driver and
enable the secondary path output driver. Notice that the two paths use
independent sets of hardware.
