AMERITECH NAMES SIEMENS STROMBERG-CARLSON SUPPLIER FOR SMDS SWITCHING
 BOCA RATON, Fla., Oct. 26 /PRNewswire/ -- Siemens Stromberg-Carlson and Ameritech Advanced Data Services have reached an agreement naming Siemens Stromberg-Carlson a key supplier for high-speed cell switching systems to be used throughout the Ameritech network for switched multimegabit data services (SMDS) and frame relay. Value of the contract was not disclosed.
 Under the agreement, which is in effect through 1994, Ameritech will deploy Siemens Stromberg-Carlson EWSM Cell Switching Systems to provide local-area network (LAN)-to-LAN connectivity and other high-speed data services to its customers. The announcement follows a successful field trial with Ann Arbor, Mich.-based CICNet, a data network firm that is providing access to the global data network internet to computer users at the University of Illinois-Chicago, Argonne National Laboratory and the University of Chicago.
 With SMDS, users access high-speed data services in the public network on an as-needed basis, eliminating the need for costly leased lines in private networks and providing connectionless access over a metropolitan or wide area. The Siemens Stromberg-Carlson EWSM system can transmit data at speeds of up to 140 megabits per second (Mbps) (equivalent to almost 10,000 pages of text per second) today, and will be upgraded to Synchronous Optical Network (SONET) speed in timeframes required by the Bell Operating Companies in the U.S. The EWSM also incorporates an interface that allows it to support frame relay services.
 "Our belief that the public network is the most efficient carrier for data services is reflected in this project to provide frame relay and SMDS services to businesses throughout our five-state region," said Michael Framer, president of Ameritech Advanced Data Services. "We recognize the strong growth potential for this area, and are committed to providing high-speed data services as competitive solutions for our customers."
 "This contract is particularly significant for Siemens Stromberg- Carlson in that Ameritech is now the second Regional Bell Operating Company to move toward commercial SMDS service based on our EWSM Cell Switching System," said Daryl Elgen, regional vice president for Siemens Stromberg-Carlson. "By providing compatibility with today's frame relay services and permiting SMDS over a wide area, the EWSM cost-effectively meets today's network challenges with a path to the future."
 The EWSM Cell Switching System is based on the IEEE 802.6 standard, and provides an evolutionary path to broadband Asynchronous Transfer Mode (ATM) service. It is an integral part of Siemens Stromberg- Carlson's Vision O.N.E. strategy, which gives carriers the ability to deploy broadband services that take advantage of immediate revenue opportunities, while maintaining compatibility with the future ATM network.
 Ameritech Advanced Data Services is a subsidiary of Ameritech Information Systems, a company formed in January 1989 to provide comprehensive, integrated systems solutions to meet the communications and information needs of large business customers. Ameritech is also the Chicago-based parent of the Bell companies serving Illinois, Indiana, Michigan, Ohio and Wisconsin, and several other information- related subsidiaries providing mobile communications, directory publishing, audiotex services and voice messaging. Its 1991 revenues were $10.8 billion.
 Siemens Stromberg-Carlson provides telephone operating companies with advanced, high-quality public telecommunications networks. The company designs, develops and manufactures central office digital switching systems, broadband switching systems, packet switching systems and transmission equipment. Based in Boca Raton, the company has manufacturing and other functional groups in Lake Mary, Fla., and Albuquerque, N.M. Siemens Stromberg-Carlson is the third-largest equipment supplier to the U.S. public telecommunications networks.
