摘要:
The invention relates to a method for establishing a telephone connection between subscribers of a first telephone net (P) to subscribers of a second telephone net (T1, T2, T3). A calling private branch exchange (N1, N2) of the first telephone net communicates a subscriber's number to a central control unit (C). Said central control unit determines the private branch exchange (N1, N2) from which the second telephone net is accessed. Subsequently, the connection to the subscriber of the second telephone net is established.

A signal processor programmed with a set of instructions to perform a data transfer encoding method. The encoding method permits communication from the signal processor to a subscriber, where the subscriber is connected to a digital network by an analog loop. The signal processor may be connected through a digital connection to the digital network. The signal processor selects a digital codeword from a set of digital network codewords. The digital network codewords may correspond to a set of quantization values applied at a line interface which couples said digital network to said analog loop. The signal processor converts the data stream into a sequence of digital codewords from the set of digital codewords. The digital codewords may then be sampled and transmitted through the digital connection to the digital network. A signal processor performing a decoder method is also provided. The signal processor receives an analog signal representing the sequence of codewords. The signal processor converts the analog signal into the sequence of codewords.

A locator system has a plurality of locator transmitters, each transmitter transmitting a unique locator signal. Paging devices are carried by each user of the locator system and each paging device includes: (i) a receiver responsive to signals broadcast from the locator transmitters, (ii) a unique identification code stored therein, and (iii) a signal transmitter and controller for controlling the signal transmitter, the controller causing the transmitter to transmit location and identification signals based upon the locator signal received by the receiver and the unique identification code. A receiver is responsive to the signals transmitted by the signal transmitters in the paging devices and a control system handles communications from other parties to the users. The control system is coupled with the receiver and responsive to received location and identification signals to determine where to direct communications from other parties intended for a user.

A method of selecting a PCM codeword set. A communication system includes an encoder and a decoder. The encoder has a digital connection to the digital portion of the telephone network. The digital portion of the telephone network is connected by an analog loop to the decoder. The method includes transmitting sequence of PCM codewords from the encoder and receiving the sequence as a sequence of analog voltages. A noise level it determined and a minimum separation value is selected in response to the noise level. A set of PCM codewords is selected such that no two PCM codewords within the set are separated by less than minimum separation value.

A paging system wherein each user carries a paging device adapted to receive radio frequency signals broadcast from a central paging system with a unique identification code assigned to each paging device. Each paging device includes a radio frequency transmitter and controller for controlling the radio frequency transmitter, the controller being operable in two distinct user selectable modes, the first such mode being responsive to receiving a signal broadcast by the central paging system and responding by transmitting predetermined data back to said central paging system.

A teleworking facility is provided with a Computer/Telephony Integration ontroller connected to a private automatic branch exchange (PABX) and arranged to select an available one of a set of terminals to receive the identity of a teleworking agent requesting work (or select the identity of a teleworking agent to be offered work), and to command an automatic call distribution (ACD) system to record the teleworking agent's identity in association with the identity of the selected terminal. When the controller detects that the ACD system has connected an incoming call to the selected terminal, it commands the PABX to make an outgoing external call to the teleworking agent at the recorded remote terminal and to join the two calls in conference mode.

A telephone system for providing enhanced telephone services. The system includes a telephone switch servicing a plurality of telephone subscribers via communication facilities of the switch, which facilities hande both voice and data communications. A telephone switch controller is coupled to the switch for controlling the switch to provide an enhanced service not otherwise available in the switch. The controller communicates with the switch using data in the form of switch functions. The controller includes a memory for storing a sequence of switch functions, swhich sequence defines the enhanced service. The controller communicates a prompt to a caller in response to a telephone call placed by the caller to a predetermined telephone address associated with a subscriber and communicates the sequence of switch functions stored in the memory to the switching system in response to a command received from the caller to provide the enhanced service.

A network call center hosted by a network service provider has equipment and software for providing call center services to customers of the network service provider. In a preferred embodiment internal connection points in a telephony switching apparatus at the network call center are provided and assigned to agents of customer call centers. The connection points are characterized in that a remote agent, dialing one of the connection points, is connected to the network call center until the agent intentionally disconnects. The network center tracks remote agents by the fact of connection, and provides call center services to groups of agents associated with the remote call centers. Different services may be provided to different remote call centers, and the network center tracks activities and bills the local call centers.
