    摘要: A system and method for providing prepaid dialtone services. The system includes a prepaid dialtone service center having an applications server that maintains a prepaid dialtone subscriber database including subscriber identification and service period information. The applications server is configured to automatically remind subscribers to renew their prepaid dialtone account and communicates with a local exchange carrier to place a hold on, or cancel, an expired subscriber account. The method includes the features of determining and monitoring a service period for a prepaid dialtone subscriber, communicating a reminder to the subscriber prior to expiration of the service period, and communicating with a local exchange carrier servicing the subscriber upon expiration of the service period.

    摘要: A method of operating a virtual private network includes the steps of: (a) dialing a custom number; (b) receiving the custom number at a switch (20) of a first carrier; (c) routing the call to a switch (18) of a second carrier based on having received the custom number; and (d) when the call to the switch (18) of the second carrier includes a plain old telephone number translation of the customer number, routing the call over the second carrier to a service switching point (26) of a third carrier.

    摘要: In a particular embodiment, the disclosure is directed to a system for identifying redirected calls that includes a service switch point and a service control point. The service switch point is coupled to a communications network. The service switch point is configured to receive a call termination request that indicates call redirection. The service control point is coupled to the service switch point and is configured to direct the service switch point to utilize a distinctive ring in response to receiving the call termination request.

    摘要: A method and apparatus for laser marking a moving workpiece such as a wire or cable directs a substantially constant rapidly pulsed laser beam at a frequency of at least 15 Hz towards a low inertia, low mass rotatable mask with character apertures disposed around its periphery. The mask is driven asynchronously to present successive characters with each pulse to form a composite image.
