Abstract: A routing system provides internet service providers with internet routing support for internet communications. The routing system receives a query from an internet service provider and responds with the appropriate internet address to transport communications over the internet. The internet address may direct the communications to an internet gateway or to the routing system itself. The routing system can forward the communications to a destination over the public telephone system. The routing system may process a telephone number to identify the proper internet address for the communication. The routing system may also provide internet gateways for use by the service providers.

Abstract: A system and method connects a call in a broadband system using the asynchronous transfer mode protocol for switching. Calls are connected over a SONET ring that has SONET multiplexers coupled by SONET paths. The SONET multiplexers are adapted to add calls to, and drop calls from, the SONET ring. An ATM cross connect system that has ATM cross connect devices is coupled to the SONET ring. The ATM cross connect devices provide provisioned ATM connections over the SONET ring. ATM interworking units are coupled to the ATM cross connect system. The ATM interworking units interwork calls with selected ATM connections in response to control messages. The selected ATM connections are provisioned between the ATM interworking units by the ATM cross connect system over the SONET ring. A signaling processor system receives call signaling for the calls, processes the call signaling to select the ATM connections for the calls, and sends the control messages to the selected ATM interworking units.

Abstract: A method and system for Connection Admission Control (CAC) in a communications network, such as an ATM formatted B-ISDN network, is provided. Using end-to-end virtual path structures and class-of-service separation, various network virtual connections may be administered using a connection server based on a weighted round robin or similar connection-serving algorithm. Network users aware of the network structure and the means by which queue lengths are determined may easily calculate a Sustainable Cell Rate (SCR) for the traffic they wish to introduce into the network path for transmission to a given destination. The user declared SCR, in addition to other user declared traffic parameters, determines the queue lengths allocated in the network switches, such that a required level of Quality of Service is maintained.

Abstract: A polarization scrambler and a polarization mode dispersion (PMD) compensation system compensate for PMD on an active optic fiber. The polarization scrambler scrambles a state of polarization of an optical signal that carries user information. The PMD compensation system then receives the optical signal over the active optic fiber. The PMD compensation system measuring a differential group delay and principal states of polarization of the PMD in the active optic fiber. The PMD compensation system then determines a modification of the optical signal based on the differential group delay and the principal states of polarization of the PMD. The PMD compensation system modifies the optical signal in the active optic fiber to compensate for PMD based on the determination of the modification. The PMD compensation system then transmits the optical signal.

Abstract: The invention provides a call processing system to handle calls to a call center by obtaining absolute address for a call center resource from a call center resource processor prior to directing the call to the call center resource. The invention includes a call center resource processor that receives an address query from a communications system for an absolute address of a call center resource. The call center resource processor processes the address query to identify the absolute address. After identifying the absolute address, the call center resource processor generates an address response with the absolute address for the call center resource. The call center resource processor transmits the address response with the absolute address from the call center resource processor for the communications system to route the call using the absolute address.

The system uses self-healing rings which are interconnected. Some of the rings are stacked within the same physical routes in order to minimize the number of ring terminals on each ring.

Abstract: The invention is a system for providing virtual connections through an ATM interworking multiplexer on a call-by-call basis. A signaling processor receives signaling for a call and selects the virtual connection for the call. The signaling processor generates new signaling that identifies the selection and transfers the new signaling to the ATM interworking multiplexer that accepted the access connection for the call. The multiplexer converts user information from the access connection into ATM cells for transmission over the virtual connection in accord with the new signaling.

Abstract: A system for reducing the influence of polarization mode dispersion (PMD) in high speed fiber optical transmission channels. A signal is forward error correction (FEC) encoded according to an FEC code that defines a specified error tolerance per codeword. The invention then effectively randomizes the input polarization of the signal before transmission, in order to reduce the likelihood that PMD will distort one or more codewords beyond the allowed error tolerance. The invention will thereby increase the PMD-limited transmission distance in an optical transmission system.

Abstract: A system and method for replicating temporary data created by a server is provided. Temporary data for a local server is replicated periodically to a remote server. Temporary data for the remote server is also periodically replicated to the local server. If a server fails, another server begins processing user requests not responded to by the failed server. The user requests are processed with the benefit of the replicated temporary data. Repetitive user input and processing to create and process the temporary data is not required.
