[GreenKeys] OT - rotary dial telephone specs

[COURYHOUSE at aol.com]

Back when I was young I had no dial at first for my lineman's butt set I  
built and used a microswitch with a lever sticking out that I could pulse and 
 dial with! Ed Sharpe _www.smecc.org_ (http://www.smecc.org/)

toggle switch in series with the line to dial...(just for  fun).  I'm sure that 
was longer than 75ms, so I also would be interested  in the limit of the 
pulse length.
 
Curious minds, etc....

So my question is what was the design standard for a dial phone's  
pulse-widths?  They both work just fine on my Centurylink landline, and  I dialed up 
my cell phone and left myself a message with each phone.   Perfect dialling 
and audio sounded good in both directions too.
