Abstract: A bidirectional chromatic dispersion system includes an optical circulator that includes four ports. A first port is coupled to a first optical transmission medium and a third port is coupled to the second optical transmission medium. A first dispersion compensating grating is coupled to a second port, and a second dispersion compensating grating is coupled to a fourth port. The first dispersion compensating grating is operative to reflect wavelengths in a first optical band, and the second dispersion compensating grating is operative to reflect wavelengths in a second optical band. The first dispersion compensating grating is substantially transparent to wavelengths in the second optical band, and the second dispersion compensating grating is substantially transparent to wavelengths in the first optical band. The first dispersion compensating grating is coupled to the second port of the optical circulator through the second dispersion compensating grating and a dispersion compensating fiber.

Abstract: A call processing platform provides the intelligence for a caller to choose a preferred dialing plan. In particular, the call processing platform includes the support for multiple dialing plans and holds information regarding which dialing plan is preferred by a caller. When the caller initiates a call, the call processing platform assumes that the caller entered the call in accordance with the preferred dialing plan of the caller. The call processing platform also includes intelligence for translating the call, if needed into a format that complies with a dialing plan for a locale from which the call was initiated. As a result, the call may be completed in the proper format. The translation is transparent to the caller. This enables a caller to use a single dialing plan even when the caller initiates calls outside of the geographical location associated with the calling plan. Hence, it is easier for the caller to place calls from outside of the native country of the caller.

Abstract: A method of optimizing a network includes a plurality of nodes interconnected by high multiplex level links, in which at least some of the links carry a number of low multiplex level remaining demands that is less than the capacity of the links, by rerouting lower multiplex level remaining demands through the network to reduce the total number of higher multiplex level links in the network. The method eliminates from consideration any bridges and spurs in the network, thereby forming one or more connected components of the network. After the spurs and bridges have been eliminated from consideration, the method reroutes remaining low multiplex level demands through each of the remaining connected components of the network to reduce the total number of high multiplex level links in each remaining portion.

Abstract: A computer security system automatically updates an access status and a level of access privilege for each user based on outside feeds related to current status of the user with respect to an organization, such as a business or school and the membership of the user in a group or department within the organization. A unique user identifier is assigned to each user across all computing systems. The computing system retains the relationship between the user and the user identifier even after the user's access to the computing system is terminated. The user may be reassigned the same user identifier should the user again be granted access to the system resources. The computing security system may be implemented as an overlay to an existing resource allocation system, such as the RACF system commonly found on many mainframe computers and may allow decentralization of certain security functions.

Abstract: A spare capacity planning tool for planning spare capacity in a transport network during a multiple-span failure following a single failure event. The spare capacity planning tool simulates restoration of a transport network regardless of the sequence of failures. The system and method utilize a permutation reducer to minimize the number of sequences to be verified during simulated or actual restoration activities. The permutation reducer reduces the number of sequences to to during simulated restoration activities to a first order function rather than a factorial function of the number of failed spans.

Abstract: A monitoring system includes multiple redundant processes for gathering and archiving information. The processes are well adapted for use within a call center which has multiple agents for processing inbound/outbound calls. The information concerns the calling activity of the agents. One of the processes is designated as a primary process for providing archived information to clients. The other processes are redundant secondary processes which assume the role of the primary process upon failure of the primary process. Once a failed process is reinitiated, a data synchronization mechanism is used to reconcile data to ensure that each of the processes has current and up-to-date information.

Abstract: A system and method is disclosed for dynamically restoring communications within a network following an outage comprising a database containing the configuration of switching elements within the network and a plurality of instructions resident on a memory device for operating a control computer, wherein the plurality of instructions includes a code segment for receiving network parameters following the outage, a code segment for selecting restoration switching elements from the database based upon the network parameters, a code segment for generating connect and disconnect commands for the restoration switching elements, and a code segment for sending the connect and disconnect commands to the restoration switching elements, thereby restoring communications within the network.

Abstract: A system and method for virtual networking work at home provides the capability to bill business calls from an employee's home telephone to the business and to bill personal calls from the same telephone to the employee. Upon entry of an access code by a caller, a second dial tone is presented to the caller, who then dials the desired virtual network station number. A signaling message containing the dialed number and the ANI of the calling station is sent to a service control point which translates the dialed number and ANI to corresponding numbers. The dialed number is translated to a telephone number which allows the call to be completed to the desired virtual network station. The ANI is translated to a number which allows correct billing of the call. The call is then presented to an inter-exchange carrier network which completes and bills the call, using the translated numbers. This allows virtual network work-at-home stations to be located anywhere in the country.

Abstract: A method and an apparatus suppresses echo in telephone communication systems having a send path and a receive path. A first filter is coupled to the send path carrying a voice signal. The first filter removes a first set of frequencies but allows either fundamental frequencies or second harmonics in the voice signal to pass through. Thus, the first filter preserves the fundamental frequencies or the second harmonics in the voice signal. A complementary filter is coupled to the receive path carrying the echo. The complementary filter is used to remove the remaining frequencies that are present in the echo. By operating jointly in a complementary way, the first filter and the complementary filter removes the echo.

Abstract: A method of and a system for transmitting a serial stream of electrical data bits by substantially simultaneously converting each bit of the serial stream of electrical data bits, or a selected subset of bits of the serial stream, into an optical bit, each optical bit having a different wavelength, and multiplexing each optical bit into a single multiwavelength optical pulse.

Abstract: A system and method for processing performance metric data and converting the data from Universal/Uniform Data Format (UDF) to a form readable by data analysis/reporting tools such as SAS IT Service Vision. Performance metric data is collected by collection agents in UDF files. Universal/Uniform Data Format files produced by the same type of collection agent are reformatted and mapped to a dataset having a number of records or observations. The datasets are sorted by grouping the records according to a characteristic such as an attribute and performance data tables are constructed from the sorted datasets in the form of SAS datasets. The SAS datasets may be read by data analysis/reporting tools that use the datasets to produce charts and graphs of computer system performance for display.

Abstract: A system and method for translating special dialing strings and/or mobile feature codes in a wireless telecommunications network. Upon receipt of a special dialing string ("SDS") or mobile feature code ("MFC"), a mobile switching center passes the SDS or MFC to a centralized processing center. The centralized processing center includes a home location register (HLR) containing an SDS lookup table and/or an MFC lookup table. The SDS lookup table includes information pertaining to the dialed string, a subscriber group number, the mobile switching center group number, and a number to be dialed (translated number). The MFC lookup tables include information pertaining to the dialed string, the subscriber group number, and feature action to be invoked. Using the SDS lookup table in the HLR, an SDS can be translated into a number to be dialed. Using the MFC lookup table, an MFC can be processed to change the mobile subscriber's profile.

Abstract: A system and method for confirming the receipt of a message by a messaging unit or pager. The system allows a caller to request page confirmation from the service provider. The system uses a caller identifier, entered by the caller at an input source, and a sequential index to store and locate data relating to the page confirmation request in a data structure. A page confirmation message is sent to the pager and the pager immediately sends a confirmation reply message back to service provider. At this point the service provider indicates in the data structure that the page was successful. At any time, the caller can then access the service provider to determine if his message was received by the pager.

Abstract: A system that processes telecommunications calls from a switch to provide call services. The system supports transactional and conversational protocols. For conversational protocols, call context is maintained at a service control point 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 comprise Communications Servers and Transaction Servers. Communications Servers are coupled by a WAN to provide distributed processing and enhance reliability and load balancing. A method processes conversational protocol messages while maintaining call context at a Communications Server. A method supports multiple-service calls by redirecting processing from one Service Application executing on an original service control point to another Service Application without communicating with the originating switch between services.

Abstract: A signaling network management system (SNMS) collects network topology, traffic, performance and fault information, correlates that information and displays the information to system operators. It includes a distributed client/server platform that receives and processes information relating to network events that is generated by various signaling network elements. Each network event is parsed and formatted to a standardized format to allow processing of events generated by any type of element. The formatted events are correlated and displayed to system operators. Correlation of the different types of events is performed using programmable analysis rules. The system also correlates signaling network events with transmission alarms and network maintenance schedule information. This allows the system operators to account for outages due to transmission events, such as fiber cuts, and to network maintenance. It also allows operator to worn maintenance personnel of maintenance impacting events.
