Switching any input channel to an output channel
timeslot is possible by merely writing the address of
the input channel in the Connection Memory location
corresponding to the output channel timeslot. For
example, to switch channel 1 to output channel 5 and
enable output drivers during channel 5, the
Connection Memory location corresponding to
channel 5 should be loaded with Hex 2001. This
word will be clocked out of the Connection Memory
during timeslot 4 and will cause the Data Memory to
clock out contents of the memory corresponding to
channel 1 during the channel 5 timeslot. The 16 bit
word clocked out by the Connection Memory will also
enable Data Memory output drivers, and, external
drivers.
2048 Channel Switch Matrix
A
interchange switch can be constructed with three
SMXs as shown in Figure 18. SMX#1 and SMX#2
are used to store data and switch it in time, while the
third SMX functions as a Connection Memory.

SMX#1 and 2 are operated in the Counter Mode and
External Mode alternatively in consecutive frames. In
any specific frame, one of the two is in Counter mode
while the other is in External mode. The functions
are reversed in the successive frame. The SMX in
counter mode is programmed to write data
