Forgive me if this is off topic but this is actually about circuitry design:
My understanding is that electromechanical Strowger SxS switches have 10 "steps". What would happen if 11 pulses were dialed, either from a phone that happened to have 11 holes in the dial and could send 11 pulses or by tapping and depressing the switchhook/hookswitch rapidly 11 times in succession?
Similarly, what about 12, 13, etc. pulses in succession?
I'm not sure if 11 pulses would dial 10+1 or simply 10 and then stop listening.
I've tried and failed to test this out, even though I have 2 PBX systems at home. I can dial the lower five digits easily using the switchhook but I fail more than half the time simply dialing 0 using the switchhook. And because the PBXs are electronic, they may automatically recognize 11 as invalid and default to a reorder signal.
If there is a difference between how electromechanical switches and electronic switches would respond, please contrast them. (I don't know how many people just have a SxS switch at home to test with though...)
