Abstract: In accordance with the principles of this invention, Pulse Code Modulation (PCM) signal streams are converted into Asynchronous Transfer Mode (ATM) cells for switching and transmission across a telecommunications network. Each cell carries one PCM sample of up to 48 different voice connections, the voice connections selected from the PCM data streams because they have a common destination. The cells are transmitted over ATM virtual circuits, each circuit transmitting one cell every 125 mu s. Advantageously, ATM transmission systems interface with PCM systems without adding appreciable delay and without requiring additional buffering. Advantageously, new voice paths can be established most of the time by using available slots in the cells of existing virtual paths. This invention can also be used for implementing a large switching system or a cluster of highly interconnected smaller systems.

Abstract: An arrangement for obtaining directory assistance automatically and without the assistance of an operator. A customer (40, 42) requesting directory assistance is connected to an automatic speech recognition unit (ASRU 14) and is prompted to speak commands for identifying the requested directory number. The ASRU converts received speech signals from the customer into data signals for searching a directory number data base (57). If a directory listing is located, the number of that listing is announced to the customer and the customer is automatically prompted to speak a command indicating whether a call to that number should be automatically established. The telecommunications switching network (12) responds to a positive command by automatically establishing such a connection. Advantageously, such an arrangement provides directory assistance service automatically without requiring special customer equipment.

Abstract: A method and apparatus for setting up a telecommunications call from a calling customer (caller) terminal (1) to one of a plurality of call destinations (25) through an interconnection network (15). The caller dials an 800 number. This number is identified in a first data base (9) as indicating a plurality of possible services, each of which is associated with one or more call destinations. A second data base (13) provides the identification of a switch (17) for generating an announcement to the customer and for the identification of an announcement in that switch. The call is connected to that announcement and an automatic speech and tone recognition unit (19), and the announcement (21) prompts the caller to speak a command or key a dual tone multifrequency (DTMF) signal in order to select one of the possible destinations. Based on the number dialed by the caller, the Numbering Plan Area (NPA) code of the caller plus the command keyed or spoken by the caller and recognized by the recognition unit, one of a plurality of POTS (plain old telephone service) telephone numbers is selected by the second data base and the call is routed to a destination identified by that POTS telephone number. Advantageously, such an arrangement permits a business to use a single directory number for serving a plurality of services of the business, to select among these services on the basis of a command spoken or a DTMF signal keyed by a caller in response to an announcement of that business, and permits the business to receive the call at an appropriate destination for processing that call.

Abstract: A vendor information service is offered utilizing the services of attendants for identifying customer requests and for taking orders, utilizing a voice processing unit (14) for announcing prerecorded information to customers and for recognizing voice commands or keyed requests. Such commands or requests may be to announce another message to a customer, to set up a connection to a telephone operator, or to connect the customer directly to a vendor. A customer is initially connected to a telephone operator (24, 25) who ascertains the basic customer request. In response to that request, the operator sets up an announcement (13) for the customer. A voice processing unit then monitors (15) the customer for voice commands or keyed requests in order to play another announcement or to set up a connection from the customer to another telephone operator or a vendor attendant (46). Advantageously, such an arrangement utilizes operator and vendor attendant time efficiently and permits advertising announcements to be played only to those customers who specifically request them.

Abstract: An electronic tone ringer responds to ringing signals on a telephone line (101, 102) while being unresponsive to dialing pulses or other signals on the line. Powered directly from the telephone line or alternatively from an external DC supply, the ringer distinguishes between valid and invalid ringing signals. A distinctive ringing capability for the tone ringer is also available through the use of two oscillators (631, 644) which allow selection of four frequencies and four modulation rates.

Abstract: A membrane is supported at its edge by an annular, tapered skirt structure. The skirt strengthens the attachment of the membrane to the support ring (55) and reinforces the edge region where the membrane would otherwise tend to fail. Stress concentrations are reduced by providing a skirt or featheredge, on the interior side of the skirt, that meets the membrane at a relatively small effective contact angle. In a preferred embodiment, the membrane is made by depositing a polysilicon layer (20) on the surface of a substrate of silica-based glass (10). A portion of the polysilicon layer (20) remains as a free-standing, tensile film supported by a remaining portion of the substrate (50).

Abstract: Methods and apparatus for automatically connecting a calling customer (40, 42) to the customer (46) identified by the directory number requested by the calling customer from a directory assistance operator (24). The calling customer need not disconnect and reoriginate a call; instead, the directory assistance system uses the directory number information located (57) in response to the calling customer's request to control (10) the establishment of a connection (12) directly. The request for such a connection is detected by the operator (24) or by a voice processing unit (14) used to monitor (15) a connection for announcing (13) the directory number to the calling customer.

Abstract: In the disclosed coded telephone ringing signal method and circuitry, audibly distinguishable ringing codes are generated by alternately shifting between at least a pair of single frequency tone at different modulation rates. Other distinguishable ringing codes are generated by changing both the modulation rates and tone frequencies utilized.

Abstract: A method and apparatus for flexibly interconnecting the nodes (9, 10, n) of a local data network to achieve reliable internodal data transmission while minimizing the extra data processing load on the host processors of each node. An interface processor (100) is provided at each node which controls transmission and reception of data packets and the communication of data from and to the location in node storage associated with the program processes which generate and receive the data. Different protocols are provided for different types of messages and are controlled by the interface processor in order to provide high reliability data transmission where needed. Destination addresses are associated with each data packet to provide flexible routing of data.
