STEP-BY-STEP SWITCHING SYSTEMS:
First automated, then variant. Patented an undertaker: rumor has it to have destination. And to have without intervention. But no, an undertaker in Kansas City, Missouri, USA. A rumor has it diverting, to have from without his business an undertaker. Rumored diversion from an undertaker. Want some way, routed clear to a destination. To undertake. But no, routed to an operator intervention.
Invention changed throughout; conceptually, the same. Rotating selectors choose a level. Pulses on a line make a level. A level one of many. Diversions. The number of pulses changed conceptually throughout. To instruct a solenoid, what’s a solenoid, to move this wiper, a wiper’s a selector. A line, a pulse, a level. A level one of many. This is all by mechanical movement, move this wiper, routed clear to a subscriber destination. Mechanical movement like an upward cascade. Rotating change of selection levels.
A level is a digit, an upward cascade. A digit is a number a figure a finger a plug—a grommet and a plug. The tone plant results from additional circuitry. To come back around, to undertake an upward cascade. And again around. Tone plant to provide progress—progress is information: does anyone remember ringback tones? To divert business from the undertaker, maybe a circuit can bounce.
