This monitoring system eliminates the need for separate latch/sense circuits presently being used in electromagnetic telephone switches. It also replaces the extra relay contact currently being used to signal the latch/sense circuits. A key feature of this monitoring system is the way it insures that both of the silicon-controlled rectifiers SCR1 and SCR2 are triggered upon computer command.
