When Alexander Graham Bell invented telephone, that time which switching system was used?
point to point network...as far as i know..
well they used and and or gates i belive and i think the first switch system was the 1ESS
you know what i did some more research and actauly the first switched telephone network arrived in Britain when The Telephone Company Ltd which opened its first public telephone exchange at its offices in Coleman Street, London BELL was the first patoned telephone service, but the Ltd was in effect an exclusive club, to which members paid a subscription - hence the origin of the term 'subscriber'. The exchange served just eight subscribers with a two-panel switchboard.
Congrats! Its Correct!
