Next year the city of Fresno, California – it’s a few miles east of Los Angeles and is regrettably, along with Bakersfield, a standing joke among Californians who don’t happen to live there will be installing a $2.9m Integrated Services Data Network system, which will work through the existing Centrex switching system to connect all city offices, the Fresno convention centre and the airport; Pacific Bell will install the system, having tested the technology at Lockheed Corp’s base in Sunnyvale, California, famous for the the fact that the company used to send microfilmed engineering drawings over the mountains to a rather inaccessible outpost via pigeon.
