It is known as Ihe big brother of (lie phone system, capable of controlling almost all aspects Of any phone call and keeping track of calling patterns. How FSS works and what Lt is capable of has been covered previously m 2r W (February, J9&4) and will ibc covered in future issues. lL may be recalled that such a system was the specific end in view’when the project that had culminated in Ibe invention of Elte Irnosistor had been launched track in the mil's. After successful accomplishment of that planned miracle in 31*47-411, further delays were brought about by financial stringency and the need for further development of the transistor Itself, In the Gariy i95U's. a Labs team began serious work on electronic, switching. As early as [£S$ r Western Electric became involved when five engineers frusn the Hawthorne works were assigned to collabnra e with the Labs on the project. The president of AT&T in I 9; wrote confidently, “A i Bell Labs, develop] nem of 1 he new electronic swilehing system ;s going full Speed ahead . We urc su re ti ns will lead to many improvements in service ami also to greater efficiency, fhc first service trial will start in Morris, Illinois in 1959,": hurtly thereafter, Kapptdsaid that the cost of the whole project would prnhfihly be $45 mtlhon. But it grad u a lly became apparent that 1 he development of a commercially usable electronic switching system— in effect, li computerized telephone C.stchange — presented va&llv greater 1 ethnical problems thitn bad been antieipitted, and that, accordingly, Bdl Labs had vastly underesl mated both the time and the investment needed i&duthejob. S he year I9;s9 passed without tbe promised first trial at Morris, Illinois; it was finally madc.in November 10 W), and quickly showed how much more work remained to be done. As lime dragged on and costs mounted, there was concern at AT&T and something approaching panic ul Well Labs.

En November !**63, au all-cleelronic switching system WITH into use at the Brown Engineering Company aL Cocoa Beach, Florida, But this was a small insinuation, essentially another test installation, serving only a single company, K uppers cone on the subject in the 1964 annual report was, for him, an almost apologetic: ’‘Electronic switching equipment must be manufactured in volume to unprecedented slundardsof reliability.... To turn out She equipment economically and with, good speed , mass production method s must be developed; hut, at the same time, there can bo no loss of precision..,," Another year and millions of dolbira later, on May 30, 1965, the ilrst commercial electric. central office was put Into service At Succasunna, New Jersey, Liven at SuccA-Suuna, only 2(10 of the town^4 JOO subscribe rs initially had tlse benefit of electronic s witching Y added speed and additional services, such ax provision for three party cnnvci'SiUionv and automatic transfer of incoming calls. But afler that. ESS was, on Its way. In January I9titi, the second commercial installation. Ihis one .serving 2, 900 telephones, went Into service in Chase, Maryland. By Che end of 1967 there were additional PSB office! in California, Connecticut, Minnesota, Georgia, New York, Florida, and Pennsylvania; by the end of Ef*70 there wen; 130 offices serving 1,8 million cnstonSers; and by 1974 there were 475 offices serving 5.6 million customers, Lhe diffcicnec between conventional switching and electronic switching is Ibc difference between "hard ware 1 * and "software”; in the former case, ma intenance is done on the spot, with screwdriver and pliers, while in the case of electronic switch mg, i [ can he done remotely, by computer, from a central point, making it possible to have only one or two technicians on duty at a time at each switching center.

The alternate ca rriers get called pa ny supervision when the tfrtimatiim location gees equal access. I lowever, there h&i been no quick action nn else part of the alternate Long distance companies to make USe of the supervision data as they would have to get equipment for passing cbe information back to the biding computer at Lhe originating point. Thus, called party answering supervision often ends up being ignored by these earners even when Ava ilabk. The luwcr rates of alternate long distance compan ics mutt be weighed against the timeout problem as it alfecis autodialing modems, One way to circumvent this is merely to set your modem lo a shorter waiting-for-corincct tunc, but this may npl provide enough time for lhe call tu go through. You could also claim cccd it for each And every one of the calls vou get billed for that doesn't actually connect but that can be vercJ tulle "consuming.
