Off Topic - Telephone design info.

[Jon Bertrand]

     
     
     I'm not quite on the correct list for this but -
     
     Do any of you know of a good book that details how the phone systems 
     work (what's a ring, what a tip, etc).
     
     Also a book that covers what regulations are involved to gizmos that 
     connect to the phone lines in a home.
     
     Basically, if I could learn how to design a telephone I'd know what I 
     need for an upcomming project.
     
     Thanks,
