NEW AMERITECH FIBER OPTIC DATA SERVICE CONNECTS MAINFRAME COMPUTER SYSTEMS

 NEW AMERITECH FIBER OPTIC DATA SERVICE
 CONNECTS MAINFRAME COMPUTER SYSTEMS
 CHICAGO, June 16 /PRNewswire/ -- Businesses with geographically dispersed data processing centers will find it easier to connect their IBM mainframe computers and equipment when Ameritech introduces its Host Interconnect Service for ESCON next year, it was announced today+.
 The new service meets the needs of customers with existing IBM ES/3090(A) and ES/9000(A) mainframe systems which employ the Enterprise Systems Connection(A) Architecture, known as ESCON(A). Introduced in 1990, ESCON combines the latest hardware, software and computer protocol technology to transmit data with greater speed, accuracy and security across greater distances than ever before. (See IBM ESCON fact sheet, to follow, for more details.)
 Ameritech Host Interconnect Service for ESCON will use Bell company fiber optics to link remote IBM host systems with other mainframe computers, local area networks, LANS, disk, tape or electronic storage systems, and high-speed printers -- whether they are located across the street or in a city up to 60 kilometers away.
 "This service will enable customers to extend the capabilities of their data centers to remote locations, without additional costly equipment," said David M. Friedman, vice president and general manager of product development and data strategy implementation for the five Ameritech Bell companies. "They will be able to share existing equipment more effectively, and integrate new equipment into existing systems more easily." For example, with our new service a business could print reports generated by all its centers at a single printer location. Or a company could store its data on disk drives in a remote office location, saving the cost of expensive floor space in a metropolitan office building," Friedman said. The service will also provide disaster recovery protection, by linking geographically separate host systems to one another over fiber optics.
 According to Friedman, Ameritech plans to introduce Host Interconnect Service for ESCON to its customers beginning in early 1993.
 This service will expand Ameritech's portfolio of high-speed data services to include transmission speeds of 200 megabits per second -- equivalent to sending 6,500 pages of typewritten text between systems in a single second.
 Ameritech's portfolio of data services includes ISDN, which can transmit data, voice and video across a single telephone line. Additional high-speed data services, including Switched Multi-megabit Data Service (SMDS) and Frame Relay Service are scheduled to be offered later this year.
 Ameritech is the Chicago-based parent of Bell companies serving Illinois, Indiana, Michigan, Ohio and Wisconsin, as well as several other information-related subsidiaries, both foreign and domestic, which provide mobile communications, directory publishing, audiotex services, systems integration, lease financing and voice messaging. Its 1991 revenues were $10.8 billion.
