given destination.
T
three-stage switching
Architecture used for very large switchers as
a means of reducing crosspoints needed for a
given number of inputs/outputs. An array
of relatively small matrixes is arranged in an
input stage, an intermediate stage, and an
output stage. The path taken by a given sig-
nal through these stages is determined by
software and will vary according to which
circuits are already in use. Unlike
PATH FIND -
ING between two discrete switchers, three-
stage switchers are carefully designed so that
all inputs are always available at all outputs;
i.e., the switcher cannot be blocked.
