Publication number: 20110239120Abstract: A feature activation system provides a mixed computing environment that includes a server and cloud computing. The hybrid model splits the execution of a communication feature between the cloud and the enterprise server installed at or with the enterprise. Service activation is linked to a portal that can communicate with either an intermediary system or directly with an entity executing computer programs in the cloud. When the customer desires to use a feature, the customer accesses the portal and activates the feature the enterprise desires. In the background, the portal instantiates a virtual machine, on any cloud platform, and then installs the feature with virtual machine on that cloud server. To execute feature, the enterprise server and the virtual machine exchange information between the server and the cloud and allow the feature to access the enterprise server or enterprise data.Type: ApplicationFiled: March 26, 2010Publication date: September 29, 2011Applicant: AVAYA, INC.Inventors: Anjur S.

Patent number: 5636247Abstract: A system for transmitting information over an OFDM channel using phase shift keying encoding employs a bit mapping encoder to reduce the crest factor (ratio of peak voltage to RMS voltage). For a 16 subchannel OFDM system using QPSK encoding, a first set of four symmetrically positioned pairs of subchannels is used to encode two bits of information on each subchannel. A second set of four symmetrically positioned pairs of subchannels is used to encode only one bit of information on each subchannel, with the resultant phasor for each pair of the second set of pairs of subchannels being orthogonal to the resultant phasor for one of the pairs of the first set of subchannels. With this arrangement, the crest factor is reduced.Type: GrantFiled: March 21, 1995Date of Patent: June 3, 1997Assignee: Lucent Technologies Inc.Inventors: Adriaan Kamerman, Anjur S. Krishnakumar

Patent number: 5513122Abstract: The present invention provides a method and apparatus for more efficiently validating high-level specifications of sequential digital systems, and in particular, those represented by hybrid models. According to the present invention, the high-level representation of a system is converted into a direct sum EFSM. An operator or a data file then provides an initial configuration or set of initial configurations of states and variable values. The method of the present invention then determines the set of configuration reachable from the initial configuration through symbolic execution of the direct sum EFSM. By representing the transitional relations of the machine as the and-product of Boolean expressions and arithmetic expressions, each class of expressions may be processed separately. When complete, the symbolic execution produces a cover of the set of reachable states. The results may then be reviewed to determine if the given specification produces unexpected or incompatible results.Type: GrantFiled: June 6, 1994Date of Patent: April 30, 1996Assignee: AT&T Corp.Inventors: Kwang-Ting Cheng, Anjur S.
