ESCON
From Wikipedia, the free encyclopedia
ESCON (or Enterprise Systems Connection) is an optical serial interface between IBM mainframe computers and peripheral devices such as storage and tape drives. ESCON is capable of half-duplex communication at a rate of 17 MB/second over distances of up to 43 kilometers. ESCON was introduced by IBM in 1990 to replace the older, slower, copper-based Bus & Tag channel technology of 1960-1990 era mainframes. The substantially faster FICON channel, which runs over Fibre Channel, is in turn supplanting ESCON.
