Abstract: A code division multiple access (CDMA) communication system reduces system self-interference and enhances system capacity by making rate selection decisions for individual speech encoders in concert with other speech encoders. The system utilizes perceptually weighted error metrics (401) as input into a rate controller (404) which determines and provides selected rates (402) back to the encoders (105). The system provides optimum voice quality and system capacity in that it allows specific encoders to decrease their rate, which improves capacity, as necessary while allowing other encoders to maintain their rates. This prevents needless degradation in voice quality at those times when system capacity needs to be temporarily increased.

Le procédé comprend les étapes de: connexion de l'enroulement primaire d'un transformateur en série avec la susceptance; dérivation depuis les réseaux à courant alternatif, d'une tension d'excitation ayant un angle de phase par rapport à une tension de phase fournie par la ligne de phase du premier réseau à courant alternatif; et application de la tension d'excitation à l'enroulement secondaire du transformateur, de sorte que la tension d'excitation se combine à travers le transformateur avec la tension de phase pour provoquer le déphasage de la tension appliquée à la susceptance. Le procédé est mis en oeuvre avec un appareil d'interconnexion à déphasage comprenant des arrangements de transformateurs en série ayant des enroulements primaires en série avec des susceptances capacitive et inductive, et des enroulements secondaires pour recevoir les tensions d'excitation dérivées des tensions de phase du premier réseau à courant alternatif. Les angles de déphasage produits par les arrangements de transformateurs en série, peuvent être modifiés soit en changeant une partie des enroulements primaires connectés en série avec les susceptances, soit en modulant les amplitudes des tensions d'excitation.

Abstract: A method for automatically transferring customer data among a plurality of central office switches comprises receiving a work order message from a central provisioning system at a message directing switch. The message directing switch is in communication with at least one message receiving switch in a local telecommunication network. Upon determining that a particular work order message received from a central provisioning system requires a coordinated data exchange, a data query is formulated in the message directing switch to retrieve specific data, such as data relating to a customer directory number from a message receiving switch. Once the data is received in the message directing switch, the data is processed and retained in the message directing switch or delivered to another switch in the telecommunications network. The method and system alleviates the need for manual retrieval and installation of specific customer line data when a directory number is moved from one central office switch to another.
