Abstract: An input message processor translates interface-specific input messages into a core and extended format. A message interpreter includes a core and extended set of instructions associated with a multi services application protocol for interpreting call processing records in response to input messages in the core and extended format. An output message processor receives output messages from the interpreter and uses interface-specific output message definitions to process the output messages into interface-specific output messages.

Abstract: Techniques for physically implementing fiber ring networks which achieve full mesh connectivity, such networks including a 2-fiber WDM ring network composed of a clockwise ring and counter clockwise ring, and a 4-fiber WDM Self-Healing Ring network. The number of wavelengths required is derived for both odd and even number of nodes on the ring. To physically set-up all required connections in the network, optimal wavelength assignment algorithms are devised so that the wavelength assignment between nodes on the ring is systematic and engenders full mesh connectivity while avoiding any possible violation of the color clash constraint. An illustrative algorithm uses a simple matrix approach for calculating the interconnection arrangement.

Abstract: An unitized monocoque enclosure for housing electronic equipment, as in a communications system central office, has side, top and bottom panels of corrugated metal. The panels comprise a continuous envelope for the structure and themselves constitute the structural support for electronic equipment shelves and the electronic equipment mounted thereby, which shelves are supported by screw members directly into a corrugation of the side panels. No additional, uprights, frame supports or braces are utilized. The resultant structure is both simple to fabricate and achieves improved earthquake resistance.

Abstract: A service control processor includes a plurality of service feature processors each corresponding to selected telephone service, and a plurality of call processing records, each corresponding to a customer of a service provider. The customer call processing records specify services subscribed to by the caller. A feature manager processor manages call processing and the implementation and execution of services by managing the individual service feature processors. In an alternative embodiment, multiple feature manager processors are included, and a trigger manager selects between them in response to call processing triggers.

Abstract: A queuing system and method to provide efficient and effective message communication between computers, processing devices, or network elements. The queue includes three tables. A message data table includes the message data. A message state table identifies several parameters about a message including a message time-stamp, state, and partition. The partition associates the message with a predetermined one of several message processors used to send and receive messages. Each message processor selects and sends only messages having a corresponding partition. The queue further includes a queued message table that lists all messages destined for a computer or other processing device that cannot receive messages. In this manner, failed messages in the queued table are taken out of a processing queue until the off-line computer or other processing device comes back on line.

Abstract: Radio ports (RPs) in an unlicensed personal communications system adaptively, autonomously set their interference threshold and/or transmission power levels. This may be done by the RP measuring the signal level on each of the available channels and then setting the interference threshold and/or power level according to these measurements. In a preferred method, the interference threshold is determined by measuring the signal level on each channel, ranking the channels in order of measured signal level, and using these rankings to determine the threshold. The transmission power level may be set with reference to the adaptive interference threshold level. This level is determined by using the system and FCC power limitations and current conditions to provide a satisfactory transmission level.

Abstract: Local Number Portability (LNP) includes two capabilities: Location Routing Number (LRN) and Message Relay Service (MRS). The LRN capability allows proper call routing during a normal call. MRS allows proper execution of telephone services such as voice messaging and automatic callback. The system and method of the present invention implements LRN and MRS at an ISCP.

Abstract: A heterojunction bipolar transistor based on the InP/InGaAs materials family and its method of making. An n-type collector layer, principally composed of InP is epitaxially grown on an insulating InP substrate by vapor phase epitaxy. The collector layer is then laterally defined into a stack, and semi-insulating InP is regrown around the sides of the stack to the extent that it planarizes with the stack top. The semi-insulating InP electrically isolates the collector stack. A thin base layer of p-type InGaAs, preferably lattice matched to InP, is grown over the collector stack, and an n-type emitter layer is grown over the base layer. A series of photolithographic steps then defines a small emitter stack and a base that extends outside of the area of the emitter and collector stacks. The reduced size of the interface between the base and the collector produces a lower base-collector capacitance and hence higher speed of operation for the transistor.

Abstract: A method and system for estimating the actual demand on a resource in a computer or communication network is taught using patterns of the traffic volume carried by the resource. Monitors on network resources periodically measure queue size and average transmission occupancy over the period. The monitors also mark times of queue overflow. Data transmission populations within the system are estimated between queue overflows and the resulting pattern is used to distinguish actual user demand that may be camouflaged by a reduction in traffic caused by the transport protocol response to lost or corrupted data transmissions.

Abstract: A novel video object extraction has a first object 12, such as a foreground object, illuminated with visible light 16 and a second object 14, such as a background object, illuminated with a combination of infrared 18 and visible light 16. A novel camera system observes the scene. The novel camera system includes an infrared light camera 24 and a visible light camera 20. The infrared light camera output 24 contains bright images of the second object 14, with relatively little brightness of the first object 12. The signal from this infrared light camera 20, once thresholded, serves as a key to remove the second object 14 from the video image captured by the visible light camera 20.

Abstract: An apparatus and method for handling international telephone numbers even in the presence of conflicting national numbering plans wherein the telephone numbers are parsed according to the nature of address of the number, such as international, national, or other. Based on this determination the remainder of telephone number is processed, including parsing the telephone number and executing error handling procedures.

Abstract: A method for broadcasting movies within channels of a wide band network by breaking the communications path into a number of logical channels and breaking each movie up into a number of segments of increasing size. The first segment of each movie is the smallest segment is transmitted in sequence over the first logical channel and repeated. The second segment of each movie which is proportionately larger than the first segment of each movie is transmitted in sequence over the second logical channel and repeated. This is repeated for the total number of segments which equals the total number of logical channels. The segments are broadcast in such a way that, once the first segment is received at a client location, the subsequent segments are also received in time, so that the movie can be viewed continuously.

Abstract: To support local number portability and service portability in a telephone network, a method and apparatus handle subscription and administrative service requests in a local service management system to maintain records at a service control point. The subscription requests include create, modify, and delete requests of records in the service control point. The administrative service requests include Numbering Plan Area (NPA) code split, mass change, and query and resend requests. The records at the service control point are accessible by switches via respective signal transfer points to determine the network addresses of the switches handling services and calls corresponding to a particular telephone number.

The system includes a graphical user interface (GUI) which is accessible through the subscriber's personal digital assistant (200), a Network Interface (304), a service control module (306), and a database (308). The system and method allow a subscriber to have all of his incoming telephone calls screened in order to identify those that are of the high importance to the subscriber. The subscriber controls this system by user-friendly interfaces to a name and telephone number database and an appointment calendar database.

Abstract: A wide area information system includes a client and at least one server on which audio data is stored. Audio data is selectively transferred to the client from the server by at least occasionally establishing a transfer connection between the server and the client. The transfer of audio data is controlled by user-selected commands and inputs that are entered via an input interface provided on the client. These commands and inputs are also transferred to the server via the at least occasionally established transfer connection between the client and the server. The audio data on the server is organized in page units that are cross-linked by way of hyperaudio links. The page units are characteristically searchable with the use of cyclically repeating directory pages of audible directory information. Finally, a data protocol is defined for enabling such an audio-based system.

Abstract: A system for connecting fiber optic telecommunications and video services to individual homes using a single twisted pair or coaxial cable line between the optical network unit and each service location. The single twisted pair or coaxial cable line connects to a broadband gateway located at the home, from which both telephone lines and other services may be delivered. Under this invention, the optical network units serve solely as connection and routing points for the drop lines, with telephone, video, and other services derived through the broadband gateway.

Abstract: Method and system for preventing copying of textual images during display on a screen. The method includes randomly adding bits to the bitmapped background of the textual image to produce two random bitmapped textual images. The random bitmapped images are then alternately displayed on the screen so that the instantaneous display of the on screen textual images is unreadable. By a second method, the bits that form the bitmapped image of the text bits are randomly modified to produce a pair of random bitmapped texts. The random bit mapped text pairs are then alternately flickered on the display screen. Again, by this second method, the instantaneous display of the on screen textual images is unreadable. Although in both cases the instantaneous display is unreadable, the human eye averages the two different bitmapped images as they alternate on screen so that the text is human readable.
