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 supplanted the older, slower, copper-based Bus & Tag channel technology introduced in 1960-1970 era mainframes. The substantially faster FICON, which runs over Fibre Channel, is in turn supplanting ESCON.
