In Matrix Switchers the activation (or closure) of a crosspoint switch is performed by a microprocessor. This microprocessor may
get its commands from one of three sources.
1) From a controller manually operated
2) From an external alarm signal
3) From an internal timer (clock)
Upon receiving a command signal the microprocessor retrieves the sequence pattern, previously stored in memory, and activates
the crosspoint switches in the proper order.
For example:
-7-
