Ima dosta interesantnih fakata, recimo: Citat: In Great Britain, the first Strowger exchange opened at Epsom in Surrey in 1912. The last Strowger switch was not removed from the British Telecom (BT) service network until June 23, 1995, when it was removed from Crawford, Scotland. Ako ste mislili da je 802.11b ruter iz 2003-ce koga ste nasli u podrumu mator :-) Ili... Citat: Almon B. Strowger was a schoolteacher and part-time undertaker. His reportedly constant feuds with manual switchboard operators inspired him to develop an automatic switching system and the dial telephone so he could bypass manual switchboard operators [102]. One reported feud concerned an alleged business loss resulting from the complete lack of privacy offered by a manual exchange. Strowger claimed that an operator at the new manual exchange in Connecticut had intentionally directed a call to a competitor Automatska telefonska centrala je posledica paranoje coveka koji je istu izmislio :-) Ili... Citat: Strowger sold his patents to his associates for $1,800 in 1896 and sold his share in the company for $10,000 in 1898. He died in 1902. In 1916, his patents were sold to Bell Systems for $2.5 million dollars. |
