Abstract: A call party profile presentation system and method for use in a multimedia-capable network for delivering a party's presentation profile to a subscriber at call setup or during the call in order to uniquely identify the party. A multimedia session engine is operable to launch a call treatment application for the subscriber with respect to a call between a call party and the subscriber. Logic associated with the call treatment application determines an appropriate portion of the call party's presentation profile to be provided to the subscriber based on subscriber selection, call party presentation restrictions, or both. A multimedia interface operable with the subscriber's terminal is actuated for delivering an indicium associated with the selected portion of the call party's presentation profile to the subscriber.

Abstract: STS-n with enhanced granularity is achieved by using an ATM cell framer which includes a plurality of cell delineators and cell assemblers for conversions between broadband STS-n which occupies at least a portion of a bandwidth of a synchronous payload envelope (SPE), such as a synchronous optical network (SONET) bandwidth, and asynchronous transfer mode (ATM) cells. The SONET bandwidth is flexibly and efficiently allocated for transporting the broadband STS-n which carries ATM data, wherein n can be varied in small increments to allow the SONET bandwidth to be shared with narrowband STS if the broadband STS-n does not occupy the entire SONET bandwidth.

Abstract: A congestion control mechanism for use with a receiver in a telecommunications network using the Service Specific Connection Oriented Protocol (SSCOP). The receiver is disposed in an access network portion of the telecommunications network such that it receives messages from an aggregate portion of the network over an Access Network Interface (ANI) and from a plurality of users over User-Network Interfaces (UNIs) in a distribution network portion. Credit windows granted by the receiver to the transmitters for transmission of message frames are managed by the receiver when it experiences congestion. The congestion control method monitors buffer usage for ANI-based traffic and UNI-based traffic in the receiver by setting appropriate buffer use counters and timers. When the number of available buffers reaches certain predetermined threshold values, the receiver sends an indication to the transmitter to restrict its message transmit window, thereby throttling the message flow therefrom.

Abstract: A system and method for enhancing reliability in a communication system. In the system and method, redundant signal paths are continuously tested to determine if any faults are present while the operating signal paths are in use. If any faults are present in the redundant signal paths, they can be addressed while the operating circuits are still in use. This minimizes the chance that a switch from an operating signal path to a redundant signal path because of a fault in the operating circuit will result in downtime.

Abstract: A multi-stage clock distribution scheme for use in a signaling server organized into a plurality of uniquely addressable shelves. The signaling server includes a system timing generator, one or more clock distribution modules arranged in a nested hierarchical manner, and a plurality of bus control modules, wherein each bus control module interfaces with at least a portion of line cards disposed in a shelf. The system timing generator provides a framed serial control signal, SFI, for controlling the operation of the multi-stage clock distribution scheme. The SFI signal encodes the IDs of the clock distribution modules and bus control modules whereby a system clock generated by the system timing generator based on a select reference input is successively fanned-out by the intermediate clock distribution modules based on address and ID information encoded in select fields of the SFI frames until the fanned-out system clocks are received by the bus control modules.

Abstract: A storage card module having a front panel card component and a rear panel transition module disposed on a backplane in accordance with the Compact Peripheral Component Interconnect (CPCI) bus standard, wherein the front panel card component is provided with at least one Small Computer System Interface (SCSI) storage medium drive. Power is supplied to the SCSI drive from a CPCI bus connector on the backplane, whereas a user-defined I/O connector on the backplane provides interconnection between the drive and the SCSI bus that is coupled to an I/O controller via an interface formed on the real panel transition module. Bus cabling coupled via the user-defined I/O connector may be used to daisy-chain other SCSI-based cards, mass storage devices, or may be terminated. A power cable deriving power from the CPCI bus connector provides auxiliary power output via a rear panel power connector to such daisy-chained mass storage devices.

Abstract: A signal transfer point (STP) includes a plurality of control and sense points that enable the STP to collect sensory information of all types and to provide control of individual pieces of equipment.

The sense points are operable to detect either a low voltage condition or a high voltage condition. The sense points are operable to monitor up to 60-volt signals and thus may monitor telecom voltage levels for US (48 volts) as well as European systems (60 volts). The sense points are optically isolated to eliminate the possibility of unwanted current flows. The control points are relays capable of handling up to a 60-volt difference in potential in its switching operations.

Abstract: In a telecommunications network (1), a signal transfer point (10) receives an Initial Address Message (IAM) generated by an originating service switching point (12) according to a call from an originating subscriber (20). The IAM includes a destination number associated with a destination subscriber (22). If the destination number has not been ported, the signal transfer point (10) sends a return message to the originating service switching point (12) indicating that no changes are to be made to the IAM. As a result, the originating service switching point (12) forwards the IAM to a destination service switching point (13) for processing of the call. If the destination number has been ported, the signal transfer point (10) performs a local number portability look-up in a database (24). The signal transfer point (10) obtains a redirection number from the database (24) for transfer in a return message to the originating service switching point (16).

Abstract: A method of auditing a first local number portability database (31) associated with a first signal transfer point (22) includes sending, by a first audit manager (26), a request to the first signal transfer point (22), the request specifying at least one ported telephone number. A first audit agent (30) receives the request at the first signal transfer point (22), looks up the specified at least one ported telephone number in the first local number portability database (31), and obtains at least one corresponding local routing number. The first audit agent (30) then sends the at least one corresponding local routing number to the first audit manage (26). The audit manager (26) then compares the received at least one corresponding local routing number to data local to the first audit manager (26). The audit manager (26) then reports the result of the comparison.
