The fiber optic system is comprised of a transmitting system, an amplification system, and a receiving system. The amplification system is comprised of a signal processing system and a laser system. The transmitting system transmits an optical signal that includes a C-band and L-band to the signal processing system. Concurrently, the laser system receives a single laser signal and transfers the single laser signal to the signal processing system. The signal processing system receives the single laser signal and the optical signal that includes the C-band and L-band, and combines the optical signal and the single laser signal to amplify the C-band and L-band of the optical signal.

Abstract: A position determining system using a first communication network, a second communication network, and a positioning system. The system may include at least one reference station that has known position coordinates and that is operable to receive first position signals from the positioning system. The reference station further may transmit position data via the first communication network in response to the first position signals and the known position coordinates. A remote central host communicatively coupled to the reference station via the first communication network can receive and store the position data transmitted from the reference station and generate and transmit correction data via the first or second communication network to provide either real-time or archived position corrections to a rover. The rover can receive its own positioning signals and, using the correction data and the position signals, can accurately determine its position.

The interface is configured to receive the first message from the communication device, transmit the second message for the communication device, receive the third message from the communication device and transmit the fourth message for the communication device.

Abstract: A director-controlled web server comprises a processing system, an interface, and a screen. Using the screen, the director selects a web site to provide content pages to participating browsers. The interface then receives refresh messages from the participating browsers and transfers the refresh messages to the processing system. The processing system generates responses with a refresh tag and the URL for the currently selected web site. The interface transfers the responses to the participating browsers. The combination of a new web site selection by the director and a refresh by the browser results in a new content page being displayed at the browser. The director-controlled web server may be configured to automatically select web sites, and to change the selection from one web site to another over time.

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: An architecture for connecting a call comprises a call processor, a signaling interface, a call process control system (CPCS), and an interworking unit. The signaling interface receives, transmits, and processes call signaling so that call signaling is received into, or transported from, the architecture through the signaling interface. The call processor processes the call signaling to select connections for calls. The CPCS receives data fills from translations, processes the data to be in a format compatible with the call processor, and fills the data into tables in the call processor. The CPCS also interfaces through the signaling processor with other systems, such as accounting systems and operations centers. The interworking unit interworks user communications between time division multiplex and asynchronous transfer mode connections and between time division multiplex connections and other time division multiplex connections.

Abstract: A system and method for caching local number portability (LNP) information comprises an LNP cache that can be located in a signaling processor. The LNP cache is a memory cache that contains the LNP information, such as the dialed number (DN) and the location routing number (LRN) for an associated DN. The signaling processor receives and processes call signaling. If the signaling processor determines that a DN may be assigned to a portable communication device, such as a portable signaling processor, then the signaling processor accesses the LNP cache to determine the LRN for the DN, if it exists. The LNP cache returns the LRN if a match is found for the DN and if the DN has a corresponding LRN. If a match is not found, the signaling processor can be configured to query an LNP service control point (SCP). Alternately, the LNP cache can be configured to include DNs that have a corresponding DN entry or a blank entry, but not an LRN entry, to signify that the DN is not ported.

The invention can interwork ISDN signaling and SS7 signaling. The invention can also process SS7 signaling to select ISDN connections and then interwork ATM connections with the selected ISDN connections. The invention can also interwork ISDN systems with non-ISDN systems.

Abstract: A method and system using mediated service logic enables telecommunications services to be provided in a first telecommunications network, even though the service logic for the telecommunications service resides in a second telecommunications network. A first service control point (SCP), located in the first telecommunications network, has a plurality of service logic modules, including a first mediated service logic module, and a second SCP, located in the second telecommunications network has a plurality of service logic modules, including a second mediated service logic module. When a service switching point (SSP) in the first telecommunications network determines that intelligent network services are required to process the call, it transmits a query message to the first SCP. The first SCP consults the relevant customer's service profile to determine which service logic module to execute to provide the requested service, and the first SCP then executes this service logic module.

Abstract: A user system uses a called number to establish a telephone call over a public telephone network to a called party. In response to the telephone call, the user system transfers a video call request to a server system over a public data network. The server system uses the called telephone number to check a database to determine if the called party is ready to receive video calls. If the called party is ready and accepts the video call, the server system exchanges video between the caller and called parties over the public data network.

Abstract: The present invention includes a method, system and apparatus for processing information bits in a telecommunications system. A network element receives the information bits into a physical port and then forwards the information bits to a MUX through an internal connection. The MUX receives the information bits from the physical port and then forwards the information bits to a functionality element through an internal connection. The functionality element receives the information bits from the MUX and then forwards the information bits to the MUX through an internal connection. The MUX receives the information bits from the functionality element and then forwards the information bits to the physical port.

Abstract: A clock recovery system recovers an optical clock signal from an optical data signal that is wavelength and data rate independent. The system splits the optical data signal into a first optical data signal and a second optical data signal. The system then transmits the first optical data signal and the second optical data signal in opposite directions around a fiber loop. In the fiber loop, the system modulates and amplifies the first optical data signal to generate a modulated-amplified first optical data signal. The system then recovers the optical clock signal after the modulated-amplified first optical data signal and the second optical data signal interact in the fiber loop.

Abstract: Methods for determining at least two pre-computed paths to a destination in a communications network are provided. The two paths are maximally disjoint. Maximally disjoint paths are paths where the number of links or nodes common to the two paths is minimized. This minimization is given a priority over other path considerations, such as bandwidth or cost metrics. By pre-computing a maximally disjoint pair of paths, the probability that an inoperable link or node is in both paths is minimized. The probability that the inoperable link or node blocks a transfer of data is minimized. Additionally, a pair of maximally disjoint paths is determined even if absolutely disjoint paths are not possible. The communications network may include at least four nodes, and maximally disjoint pairs of paths are pre-computed from each node to each other node. A third path from each node to each other node may also be computed as a function of bandwidth or a cost metric.

Abstract: A system and method provide enhanced services for a call that is transported from a communication device through an asynchronous transfer mode system. The call has user communications in asynchronous transfer mode cells and call signaling. A signaling processor receives the call signaling and processes the call signaling to determine a connection to a service platform. The signaling processor transports a processor control message designating the selected connection. An asynchronous transfer mode interworking unit receives the user communications from the communication device and the processor control message from the signaling processor. The asynchronous transfer mode interworking unit converts the user communications from the asynchronous transfer mode cells to a format compatible with the service platform and dynamically transports the user communications to the service platform in real time. The service platform processes the user communications.

Abstract: A method and apparatus are disclosed for providing pre-pay and post-pay calls. After receiving a pre-pay call, an integrated service platform obtains and transfers a pre-pay destination number and a pre-pay validation parameter to a switching system. The switching system then releases the pre-pay call extension to the integrated service platform and extends the pre-pay call using the pre-pay destination number. As the pre-pay call is in progress, the switching system monitors a duration of the pre-pay call and terminates the pre-pay call if the duration meets or exceeds a pre-pay amount indicated by the pre-pay validation parameter. In this manner, integrated service platforms, as required by prior approaches, are no longer required to be connected to the pre-pay call for the entire duration of the pre-pay call. Rather, an integrated service platform can request and receive authorization and call destination information, then be released for use by other calls.

Abstract: A system and method for connecting a call processes call signaling to determine if a call is a ported call or a non-ported call. A signaling processor determines if a ported number parameter (PNP), such as a forward call indicator (FCI) bit M and/or a ported number generic address parameter (GAP), is present. If the PNP is not present and the signaling processor determines the dialed number is a member of a portable number plan area and central office code combinations (NPA-NXX), the signaling processor queries a ported number database (PNDB). The PNDB responds with the called number dialed digits if the call is not a ported call or a location routing number (LRN) if the call is a ported call. The signaling processor appends a 1 to the nature of address (NOA) subfield of the called party number (CdPN) field if the call is a ported call.
