Abstract: An automated speech recognition system comprises a preprocessor, a speech recognizer, and a task-independent utterance verifier. The task independent utterance verifier employs a first subword acoustic Hidden Markov Model for determining a first likelihood that a speech segment contains a sound corresponding to a speech recognition hypothesis, and a second anti-subword acoustic Hidden Markov Model for determining a second likelihood that a speech segment contains a sound other than one corresponding to the speech recognition hypothesis. In operation, the utterance verifier employs the subword and anti-subword models to produce for each recognized subword in the input speech the first and second likelihoods. The utterance verifier determines a subword verification score as the log of the ratio of the first and second likelihoods.

Abstract: An NPA split management system and associated methods for receiving from a user descriptive instructions regarding an upcoming NPA split, and responsively updating components of the Intelligent Network to reflect corresponding changes in the NPA codes assigned to lines, subscribers, services, etc. A user interface operating in conjunction with a Service Management System allows the user to declare an NPA split and define its characteristics, including the old NPA code, the new NPA code, the central office codes to be “transferred” to the new NPA, and the dates of beginning and end of the permissive dialing period (PDP). The SMS contains indicia corresponding to SMS-managed databases, or tables, records, or fields thereof, which definitively specify whether the data contained therein is affected by an NPA split. The SMS determines which items require updating to the new NPA code, and on which components the affected databases or services reside.

Abstract: A system and method for measuring the approximate distance and direction of a mobile unit from a plurality of cells in order to determine whether and how to handoff the mobile unit and which cell may be the best serving cell. The CDMA timing system is used to provide an estimate of the subscriber's location to be determined by a CDMA base station. A distance calculation is made by the serving cell site sending a request for signal strength message to a mobile unit. The mobile unit measures pilot signal strength and a time offset from the expected time of such pilot signals. The signal strength and time offsets are returned to the cell site. a processor in the system can then determine if a handoff is really desirable, and with which of the cell sites is the best serving all for the mobile unit the mobile unit with a high degree of confidence that the call will be maintained.

Abstract: A circuit card face plate with an elastomeric, electrically-conductive seal that provides electromagnetic compatibility sealing and air flow control for a front panel of an electronic equipment frame. The seal gasket is in electrically-conductive contact with the face plate and an adjacent face plate, thus, with all cards in place, an air flow barrier and an electrically-conductive surface is established. To this end, an elastomeric, electrically conductive seal in a modified figure-eight cross-section provides a close fit with minimal lateral pressure being exerted on adjacent cards. Further a pin on both the top and the bottom of the face plate inserts into a hole on an upper and lower rack shelf maintain alignment of the cards when they are in the frame.

Abstract: A wireless repeater comprising a first antenna for receiving a first signal from a wireless terminal and for transmitting the first signal along a first path; a second antenna for receiving a second signal from the wireless terminal and for transmitting the second signal along a second path; a summing circuit for receiving the first signal from the first path and the second signal from the second path, for summing the first signal and the second signal to form an aggregate signal, and for outputting the aggregate signal along a third path; a delay in the second signal that makes the second signal path longer than the first signal path; and a third antenna for receiving the third signal from the third path and for transmitting the third signal.

Abstract: A system for automatically providing an incoming calling line identification (ICLID) to a paging system, so that a called party knows who called (or, at a minimum that a call was received) when he/she is away from a telephone. By this method, the calling party does not have to know any other numbers besides the called party's base number, and does not have to know PIN or other identification systems for use with a paging system. An incoming calling line ICLID is received, and the call is completed either to an answering machine on the customer premise or, alternatively, to a voice mail system. The customer premise device waits until the line has cleared and then dials a telephone number of a paging service, optionally entering any PIN number or other code number and then outpulses the received ICLID to the paging service. The paging service then pages the called party, and causes the ICLID to be displayed.
