Abstract: Generating oscillator signals with which selected signals may be mixed. Such oscillator signals may be generated by dividing a pilot tone, such as a 120 MHz pilot tone found on many cable TV systems. Oscillator signals for demodulating received selected signals may be similarly generated.

Abstract: Methods and apparatus for controlling and retrieving messages from multiple voice mail systems used by a single individual are described. A voice messaging retrieval and forwarding (VMRAF) system checks a subscriber's voice message systems for messages, retrieves the messages and forwards them to the subscriber as attachments to E-mail files. E-mail replay messages are used to control deleting of the messages from the original systems. Prompt messages played to callers by different voice messaging systems before they leave a message can be updated automatically. This is done by indicating to the VMRAF system when one or more prompt messages are to be updated and which messages, from a set of prerecorded messages, are to be loaded into the voice message systems to replace the existing prompt messages. Accordingly, the VMRAF system facilities message retrieval and the updating of prompt messages, e.g., on a preselected schedule or at preselected times.

Abstract: The disclosure is directed to a new software component, an enterprise application server component such as an enterprise bean, called a “functional bean,” which models a business method, and accords transactional persistence. The functional bean can be developed as a derived object from an enterprise bean class, and can call other beans to execute a transaction. A client initiates a transaction by requesting a container using an EJBObject of an appropriate functional bean type. A Service Manager bean handles an appropriate instance of a functional bean. After the Service Manager creates and returns the requested handle to the client, the client thereafter can access the functional bean directly. In this way, transactional awareness to the client is achieved. In a second embodiment, the Service Manager is implemented as a stateless session bean, and other functional beans are implemented as entity beans.

Abstract: Interfacing to and controlling POTS line conditioning devices using a Voice Interface Unit (VIU) are described. Technicians perform tests and checks while a POTS line is in a conditioned state. The VIU provides a centralized voice input/voice output interface allowing technicians to identify and request various conditioning options using speech. The VIU identifies a line conditioning unit to be used to test a line corresponding to a phone number via a database lookup. The VIU controls the identified line conditioning unit to connect to the POTS line. The VIU provides the technician with an easy to use voice input/output universal interface irrespective of the particular manufacturer/model of line conditioning device by performing conversions to the various protocols and instruction sets used by different manufactures. The VIU includes individual security controls and multiple access levels. The VIU may include load/simulator, call back, and keypad test capability.

Abstract: Techniques for generating, distributing, and using speech recognition models are described. A shared speech processing facility is used to support speech recognition for a wide variety of devices with limited capabilities including business computer systems, personal data assistants, etc., which are coupled to the speech processing facility via a communications channel, e.g., the Internet. Devices with audio capture capability record and transmit to the speech processing facility, via the Internet, digitized speech and receive speech processing services, e.g., speech recognition model generation and/or speech recognition services, in response. The Internet is used to return speech recognition models and/or information identifying recognized words or phrases. Thus, the speech processing facility can be used to provide speech recognition capabilities to devices without such capabilities and/or to augment a device's speech processing capability.

Abstract: There is provided a method for determining a topology for a network. The method comprises the steps of obtaining data that describes a requirement for a service between a first node and a second node, and searching a state space to define a solution that fulfills the requirement. The solution provides a topographic arrangement for the first node and the second node in the network. There is also provided a system for determining a topology of a network.

Abstract: There is provided a system for testing modem training of a first modem and a second modem. The system includes a line simulator interposed between the first and second modems, and a processor for (a) controlling the line simulator to simulate a line length, (b) controlling the first modem to train with the second modem, and (c) saving data related to the modem training.

Abstract: A signal acquisition device captures signals from a telecommunication line such as a local loop. The captured signals are spectrally analyzed using a signal-processing unit. The output of the signal-processing unit—in the form of a test spectrum—is provided to a signal identification system. The signal identification system comprises at least one of a plurality of spectra of known signals stored as templates. Using a matching algorithm, the spectrum of the test signal (unknown signal) is correlated with spectra of at least two known signals. The unknown signal is determined to be the same type as that of the known signal with whose spectrum the unknown signal produces the largest absolute correlation score. Alternatively, an unknown signals is determined to be that of a known signal if a correlation of both signals results in a score the absolute value of which is greater or equal to a predetermined threshold level.

Abstract: There is provided a method for specifying an operation via a graphical interface. The method comprises the steps of examining an image to distinguish a first bordered region within the image; examining the image to distinguish a second bordered region within the image; and determining a functional attribute of the second bordered region based on a position of the second bordered region relative to the first bordered region. There is also provided a system for specifying the operation via a graphical interface.

Abstract: A telecommunications system provides telephone services to subscriber locations over dedicated optical fibers which extend in a “star” configuration from a telephone central office. A transmultiplexer installed at the central office is connected between a digital switch and the optical fibers. The transmultiplexer has a plurality of FDM ports, each of which is connected to a respective one of the optical fibers. The transmultiplexer is connected by one or more TDM ports to the digital switch. Preferably, the transmultiplexer provides a concentrating function whereby the number of subscriber lines served by the transmultiplexer is greater than the total voice-grade channel capacity of the connection between the transmultiplexer and the digital switch.

Abstract: Methods and apparatus for activating telephone services in response to speech are described. A directory including names is maintained for each customer. A speaker dependent speech template and a telephone number for each name, is maintained as part of each customer's directory. Speaker independent speech templates are used for recognizing commands. The present invention has the advantage of permitting a customer to place a call by speaking a person's name which serves as a destination identifier without having to speak an additional command or steering word to place the call. This is achieved by treating the receipt of a spoken name in the absence of a command as an implicit command to place a call. Explicit speaker independent commands are used to invoke features or services other than call placement. Speaker independent and speaker dependent speech recognition are performed on a customer's speech in parallel.
