Matrix Switching
Basics
An
obvious advantage
of a
partial
matrix
is
that
fewer
matrix
cards are
needed. Another reason
to
use a
par-
tial
matrix
is
to
keep
specific
devices
from
being
con-
nected
directly to
other
devices.
For
example^, a
source
connected
to
rows
5, 6,
7
or 8 (Figure 2-12)
cannot be
connected
to
a
column
of
Model
7012
#1
with one
"ac-
ddentai"
crosspoint
closure.
Three
specific
crosspoints
must
be
closed
in
order
to
route the source signal
to
a
column
of
card
#1.
