Abstract: An approach for providing a quality indicator in support of a communication session between a near end station and a far end station over a data network. The quality of the communication session in a direction of the near end station sending to the far end station is determined. A message containing statistics associated with the communication session is transmitted according to a prescribed protocol to the near end station to notify the near end station of the quality of the communication session. The prescribed protocol supports real-time data exchange. The present invention has particular applicability to SIP (Session Initiation Protocol) IP (Internet Protocol) telephony services.

Abstract: An approach for providing instant messaging (IM) services is disclosed. A request is received from a source client to establish communication with a destination client associated with a subscriber over a first IM environment, wherein the request specifies a first user name derived from a unique identifier of the subscriber. A unique identifier is determined from the first user name. Further, a profile of the subscriber is accessed based on the unique identifier to determine a second user name corresponding to a second IM environment. An IM session is established between the source client and the destination client over the first and second IM environments using the respective first user name and second user name.

Abstract: A method and device for preventing fraud in collect calls from a domestic origin point to an international terminating point through a long-distance telecommunications system is described. In the system and method, a Screening for International Calls database is added to the call processing platform. This Screening of International Calls database contains records keyed by country codes, and each record has a blocked collect call field listing destination numbers that are blocked from receiving collect calls. When a domestic-to-international collect call is made, the record corresponding to the country code of the international terminating point of the collect call is retrieved from the Screening for International Calls database. This record is checked to determine if the destination number of the collect call matches any destination numbers listed in the blocked collect call field of the country code database record. If there is a match, the call is blocked.

Abstract: The invention provides a highly resilient network infrastructure that provides connectivity between a main network such as the Internet and a subnetwork such as a server-based (e.g., web server) local area network. In accordance with the invention, a network interface incorporated into a server hosting center provides a resilient architecture that achieves redundancy in each of three different layers of the Open System Interconnect (OSI) stack protocol (i.e., physical interface, data link, and network layers). For every network device that is active as a primary communication tool for a group of subnetworks, the same device is a backup for another group of subnetworks. Based on the same connection-oriented switching technology (e.g., asynchronous transfer mode (ATM)) found in high-speed, broadband Internet backbones such as that provided by InternetMCI, the network interface architecture provides a high degree of resiliency, reliability and scalability.

Abstract: A method for predicting polarization mode dispersion (PMD) in an installed optical fiber. Values of PMD are measured for a first optical fiber at various points in time during the manufacture and installation of the first optical fiber. Values of PMD are identified that correspond to sensitive ones of the various points in time. A set of correlation coefficients is calculated based on the values of PMD corresponding to the sensitive ones of the various points in time. An installed value of PMD for a second optical fiber is predicted based on the set of correlation coefficients.

The method includes generating an input ATM setup message at the calling party CPE that includes a VToA designator and a called party phone number, extracting information from the input ATM setup message, analyzing the information, designating an ATM address of a called pany CPE to be stored in the first parameter of an output ATM setup message, determining if private address translation is needed, designating the ATM address of the called party CPE to be stored in a first instance of the second parameter of the output ATM setup message, designating an ATM address of an egress ATM edge switch to be stored in the first parameter of the output ATM setup message, and generating an output ATM setup message.

Abstract: Methods and systems are provided that use resources more efficiently for calls originating and terminating in a first address space that use services in an IP address space. A call is established from an originator in a first address space to an IP device within an IP address space. The IP device sends a message to a switch in the first address space indicating a new destination in the first address space. The established call is released and a second call is established from the originator in the first address space to the new destination in the first address space. In another implementation, a first leg of a call is established to an IP device from a first address space. The IP device establishes a second leg of a call to a destination in the first address space. The calls are bridged and resources released.

Abstract: An integration component assists in the integration of information distribution systems (IDSs). The integration component may help to identify the scope of the systems that are to be integrated using a multi-level top-down approach. The multi-level top-down approach may include five levels: a system software level, a business process level, a business rule level, an interface function level, and a data level. A fault detection component may then check the identified systems to identify potential faults. This check can be performed by representing the business rules as a Transition-Directed-Graph (TDG) and then processing the TDG using generic depth-first search (DFS)-based algorithms.

Abstract: Apparatus and method for providing a termination point for service emulation instances in an access network is provided. In an embodiment, the service emulation instances are implemented utilizing, for example, pseudowires. Communications to and from the access network are aggregated and transmitted via one or more pseudowires to a service emulation instance terminator. The service emulation instance terminator converts the traffic to its native form and, if necessary, converts the traffic to a different type of format or service. The service emulation instance terminator then frames the traffic for the appropriate type of service and transmits the traffic to the service edge. Traffic received from the service is removed prepended with a pseudowire label and aggregated with other traffic. The aggregated traffic is transmitted to the customer via the access network. If necessary, an interworking function may convert the traffic from one type of service to another type of service.
