Abstract: Apparatus and a method for serving telecommunications customers, using the transmission capabilities of a Packet Network. A customer having Customer Premises Equipment (CPE) that includes a Customer Premises Equipment (CPE)/Gateway for communicating with a Packet Network, is connected to a port of the Packet Network. The customer is connected to the Gateway of a Home Switch via the Packet Network, and is also connected to Gateways of one or more Guest Switches. The customer has telephone numbers in the Home Switch and each of the Guest Switches. Callers can call the customer as if that customer were directly served by the Home Switch or any of the Guest Switches. Advantageously, the customer and callers to that customer are billed only for the short, usually local, call rate from the selected Home or Guest Switch. Advantageously, the customer can make outgoing calls dynamically via any of the Guest Switches.

Abstract: Wireless communications for frequency-selective fading channels is realized by employing a system including orthogonal frequency division multiplexing (OFDM) in combination with an at least two antenna transmit diversity arrangement. Specifically, OFDM converts a multipath channel into a plurality of narrowband subchannels each having flat fading. Then, the signals on the same frequency subchannels of the at least two antennas are grouped together. Considering a first frequency subchannel, during a first OFDM time interval, a first signal and a second signal are transmitted on the first frequency subchannel from a first antenna (0) and from a second antenna (1), respectively. During a second OFDM time interval, a reverse sign (?) complex conjugate of the second signal and a complex conjugate of the first signal are transmitted from the first antenna and the second antenna, respectively.

Abstract: A wireless telecommunication system receives information from a wireless mobile unit and determines that the wireless mobile unit is within a designated region. Information specific to the designated region is received at a centrally located location-based message server. As the traveler enters the designated region, the wireless mobile unit then receives information specific to the designated region such as information relating to traffic problems or desired locations within the region. Alternatively, a problem is identified and designated as relating to a particular region, and wireless mobile units within the designated region are then identified so that information relating to the problem can be output thereto. As such, information specific to a region occupied to a traveler is received.

Abstract: A method and apparatus are disclosed for analyzing the operation of one or more network gateways, such as firewalls or routers, that perform a packet filtering function in a network environment. Given a user query, the disclosed firewall analysis tool simulates the behavior of the various firewalls, taking into account the topology of the network environment, and determines which portions of the services or machines specified in the original query would manage to reach from the source to the destination. The relevant packet-filtering configuration files are collected and an internal representation of the implied security policy is derived. A graph data structure is used to represent the network topology. A gateway-zone graph permits the firewall analysis tool to determine where given packets will travel in the network, and which gateways will be encountered along those paths.

Abstract: A single-stage all-pass optical filter is disclosed that may be applied to generate a large tunable delay of an optical pulse train. The all-pass optical filter includes an input port for receiving an input optical pulse having a regular repetition rate; an output port; a splitter/combiner; and one feedback path. A plurality of frequency-dependent time delay periods are applied to the input optical pulse so that the filter is characterized by a time-delay spectrum having a plurality of delay peaks. The free-spectral range (FSR) of the filter, i.e., the spacing between the delay peaks, is matched to the regular repetition rate of the input optical pulse. This matching is accomplished by the FSR being equal to the repetition rate or offset from the repetition rate to a sufficiently small degree that each frequency of the pulse train will fall within the bandwidth of one of the plurality of delay peaks.

Abstract: A system and method for processing an unsolicited error message is disclosed. Generally, a first computer is utilized comprising a transceiver, software stored within the first computer defining functions to be performed, and a processor configured by the software to perform the steps of: parsing an error message to determine an identification number that represents a most significant meaning of the error message; and, determining a description of the error message after parsing. The identification number is determined by dividing the error message into an identifier portion and a series of properties portion, wherein the identifier portion provides a general description of a cause of the error message, and the series of properties portion provides specific attributes of the error message. The identification number is then processed in accordance rules provided to the system for processing the error message.

Abstract: In an event monitor associated with an information processing system, data values corresponding to monitored events are processed using a set of parameters characterizing a reference distribution of the data values. From a given one of the data values a corresponding probability value is computed utilizing the set of parameters. A thresholding operation is then performed on the probability value, and alarm information is generated based on the result of the thresholding operation. The set of parameters are periodically updated to take into account one or more of the data values.

Abstract: A method and apparatus are provided for transferring an ATM call. A first ATM call (124) is established between a first party (120) and a second party (116) and a second ATM call (128) is established between the second party (116) and a third party (118). The first and second ATM calls both include a plurality of segments (124a–d, 128a–d) or connections that are coupled to a plurality of ATM switches (208, 210, 212, 214) over ATM facilities to provide virtual connections. The transfer is accomplished by sending a message to the ATM switch over the ATM facility (109) to request the transfer of the first party to the third party. The message identifies the first ATM call and the second ATM call. The switch makes a new connection (220) between the first ATM call and the second ATM call and releases the segments of the first and second ATM calls that connect the ATM switch to the second party. As a result, the first party and the third party are connected for communication.
