摘要:
A network architecture and service platform for providing virtual private network ('VPN') over an ATM network (110). The architecture provides services for voice, video and data traffic among multiple VPN customers over a shared ATM network by implementing intelligent control devices (150a) to perform enhanced processing of ATM call set-up messages, including validations and routing translations. Hierarchical routing mechanism provided by ATM, along with customized customer addressing schemes, are used to overlay customer VPNs (115a) as higher-level networks onto the shared ATM network. The control devices translate customer ATM VPN address to internal ATM network addresses. The ATM switch (120a) network then performs lower-level network processing, using internal network addressing to set-up a virtual connection for a VPN call. The intelligent control devices may also explicitly state the end-to-end route.
摘要:
A system that processes telecommunications calls from a switch (612) to provide call services. The system supports transactional and conversational protocols. For conversational protocols, call context is maintained at a Service Control Point (603, 605, 607) during call processing. Transactional and conversational messages are mapped to and from a generic message structure to simplify the input and output interfaces of supported service applications. Service Control Points (603, 605, 607) comprise Communications Servers (602, 604, 606) and Transaction Servers (608, 610). Communications Servers (602, 604, 606) are coupled by a WAN (600) to provide distributed processing and enhance reliability and load balancing. A method processes conversational protocol messages while maintaining call context at a Communications Server (602, 604, 606). A method supports multiple-service calls by redirecting processing from one service application executing on an original Service Control Point (603, 605, 607) to another service application without communicating with the originating switch (612) between services. The other service application may execute on a separate Service Control Point (603, 605, 607) to the original Service Control Point (603, 605, 607) by a WAN (600).
摘要:
A one-number communications system (100) enables completion of calls to designated terminals by use of a single telephone number. The system includes a local wireline switch (120) and a local wireless switch (130) coupled to respective terminals (104, 106, 114, 116). A switched telephone network (140) is coupled between the switches and defines a combined switching arrangement for directing and completing calls to and from the terminals upon receiving routing instructions. A database management system (210) is coupled to a data signaling network (162) and is accessible to the switches. The management system includes a telephone number (180) assigned for use by the subscriber and routing instructions assigned to the telephone number (152, 154). The wireline switch sends a request for routing instructions from the management system for completing the call to the telephone number. The management system sends a response message to the wireline switch containing the routing instructions for completing the call to at least one of the terminals.
摘要:
A self-healing optical network carrying traffic between first and second optical linear terminals (NODE A, NODE B, NODE C, NODE D). The self-healing optical network including first, second, and third optical switching units (210, 216, 226, 232), first, second, and third spare optical channels (214, 220, 222, 228), and a working optical channel (212, 218, 224, 230). The first, second, and third optical switching units are coupled in a ring configuration using said first, second, and third spare optical channels. The first and second optical switching units are coupled by the first spare optical channel and by the working optical channel. The first and second optical switching units each direct the traffic between the first and second optical linear terminals along the working optical channel or along the second and third spare optical channels in the event the working optical channel is not available.
摘要:
An advanced intelligent network gateway (102) that allows communication between telecommunications network component that use different protocols. In one embodiment, the advanced intelligent network gateway is used to communicate between a manual operator console (122A-122N) that are processing a customer's telephone call and a service data point (128) which is a database containing information needed to process the customer's telephone call. However, the advanced intelligent network gateway may also be used to receive and transmit messages between other telecommunication components. In addition, methods for protocol conversion of a transaction capabilities application part (TCAP) message from a user data protocol/Internet protocol (UDP/IP) to a transmission control protocol/Internet protocol (TCP/IP) implementation or vice versa. Methods for receiving and transmitting transaction capabilities application part messages are also described.

A system and method for optimizing the performance, in a multichannel optical transmission system, of (100) an optical regenerator, by compensating for input signal power fluctuation and for output signal gain change, and by mildly filtering individual wavelengths (110 and 112) between gain block (140) stages. A system and method to provide amplification and refinement of a bidirectional optical signal (100) in a signal amplification and refinement stage.
摘要:
A system and method for routing telephone calls, data and other multimedia information through a hybrid network which may include transfer of information across the internet. Profile information is utilized by the system throughout the media experience for routing, billing, monitoring, reporting and other media control functions. The system can include prioritized routing. The system can also facilitate callback sessions and present a display to a caller via a web page that includes status information pertaining to the callback session. Calls and callbacks can also be routed over the hybrid network. Through use of the system, users can manage more aspects of a network than previously possible, and may control network activities from a central site.

A stable switched multifrequency source (104) is described. The stable switched multifrequency source (104) includes a narrowband reflective optical filter bank (206). This bank (206) includes a plurality of narrowband reflective optical filter devices (208). In one embodiment, the stability and precision of the reflectivity of the narrowband reflective optical filter devices (208) are further enhanced through regulation via temperature (308) and/or bias current (128) based on a comparison of the output wavelength and a precise stable wavelength reference (134). The stable switched multifrequency source (104) also includes an optical switch (202) that is coupled to each of the narrowband reflective optical filter devices (208).
摘要:
A telecommunications system includes multiple services. For example, the system provides multiple communications services with a single number for a subscriber. The subscriber can easily configure, manage and update these services via the Internet, by accessing a service or subscriber profile detailing the services specific to the subscriber. The subscriber profile specifies which communication services the subscriber wishes to provide to different people who call the subscriber's telephone number. The system provides a World Wide Web access method to the subscriber's profile. The system includes security safeguards to ensure security to the system.
