Abstract: An electrical circuit assembly includes an electrical circuit substrate having a first side; a heat sink including a metal base plate having a first side and a second side, and a plurality of fins extending from the second side; and a thermally conductive and electrically insulating adhesive directly interconnecting at least a portion of the first side of the electrical circuit substrate with the first side of the base plate.

Abstract: An electrical circuit assembly includes a flexible electrical circuit having a first side; a heat sink including a metal base plate having a first side and a second side, and a plurality of fins extending from the second side; and a thermally conductive and electrically insulating adhesive directly interconnecting at least a portion of the first side of the flexible electrical circuit with the first side of the base plate.

Abstract: A method and device for preventing fraud in collect calls from a domestic origin point to an international terminating point through a long-distance telecommunications system is described. In the system and method, a Screening for International Calls database is added to the call processing platform. This Screening of International Calls database contains records keyed by country codes, and each record has a blocked collect call field listing destination numbers that are blocked from receiving collect calls. When a domestic-to-international collect call is made, the record corresponding to the country code of the international terminating point of the collect call is retrieved from the Screening for International Calls database. This record is checked to determine if the destination number of the collect call matches any destination numbers listed in the blocked collect call field of the country code database record. If there is a match, the call is blocked.

Abstract: A method and device for preventing fraud in international calls in a long-distance telecommunications system, where selected customers can avoid fraud control blocks and greater granularity is achieved in blocking international destinations. In the method and device, an override flag is created in the records of the Billing Number Screening (BNS) database. When a call is made using a billing number whose corresponding record has the override flag set, the call is not stopped by fraud control blocks on certain international destinations. In addition, international destinations can be blocked with greater specificity because a Country Set Logic (CSET) field is added to the International City Code Database. The addition of CSET to this database allows particular international city destinations to be blocked from certain origin points.

Abstract: An approach provides detection of unauthorized use of data services. A fraud case is created for a data call that is determined to be potentially fraudulent based on a fraud alert. A fraud score is determined for the case according to the fraud alert. The fraud score is adjusted according to adjustment criteria including an intermediate network involved with the data call, and an originating country of the data call.

Abstract: An approach provides detection of unauthorized use of data services. A determination is made as to whether connections supporting remote access to a data network are completed. The number of completed connections associated with a selected attribute is tracked over a time period. It is then determined whether the number of completed connections satisfies a connection frequency threshold. A fraud alert is generated if the connection frequency threshold is satisfied.

Abstract: An approach provides detection of unauthorized use of data services. The number of data calls for access to a data network is tracked over a predetermined time period, and the cumulative duration of the data calls is determined. Thereafter, a determination is made as to whether the number of the data calls and the cumulative duration satisfy, respectively, a first threshold and a second threshold. A potential fraudulent use of the account is determined, if the thresholds are satisfied.

Abstract: An approach provides fraud detection in support of data communication services. A threshold corresponding to a geographic location is set. The threshold corresponds to duration of a call supporting data communications. It is determined whether the call duration exceeds the threshold. A fraud alert is generated if the monitored call duration exceeds the threshold.

Abstract: An approach provides fraud detection in support of data communication services. A list of single-event attributes (e.g., hot or cold attributes) is generated and includes a network address of an end user host originating a data call or a calling party identification (e.g., Automatic Number Identification (ANI) or an originating Calling Line Identification (CLI)) for network access, wherein entries of the list specify values of the hot attributes. An attribute value associated with the data call is compared with the entries. A fraud alert is generated if the attribute value matches one of the entries.

Abstract: An approach provides fraud detection in support of data communication services. A usage pattern associated with a particular account for remote access to a data network is monitored. The usage pattern is compared with a reference pattern specified for the account. A fraud alert is selectively generated based on the comparison.
