new service-oriented AT&T, a newly independent NCR, and the new telecom equipment business which would later be named Lucent Technologies. On December 15, the former AT&T-CS operations were shut down, signaling the end of AT&T's involvement in designing computer systems. Three AT&T-CS employees went into the new NCR, 25 stayed with AT&T, and the rest (about 200) went to Lucent. Many former AT&T-CS employees have been employed by Schaumburg, IL-based Motorola.
