  • a feature of the present invention that is related to the flexibility of the assigning or associating telephony services with a service card is the Open Language Assignment capability of the present invention. This feature allows a telephony service card to be issued to a user without a preferred user language being specified.
  • the present invention requests the user to choose a preferred language that is to be used in all further system responses.
  • this feature is particularly useful for third party telephony service card providers that transition to using the present invention with an existing clientele of telephony card users. That is, if the card users from this existing clientele include speakers of a number of languages, then introductory greetings on first activation of the present invention by each of these card users may be in each of these languages, requesting that the card user indicate the language of choice for subsequent system responses. Note that since this is an automatic procedure involving only the card users, there is a substantial cost savings over other language data gathering techniques wherein there are one or more manual operations, such as mailing user request forms and/or manually updating system databases.

  • call me forwarding number(s) This aspect of the call me service allows a card user or purchaser to program the service card.
  • the card user may define a single telephone number which will be speed dialed upon subsequent activations of the card's telephony services.
  • the card may be programmed to speed dial a telephone number related to a menu of telephone numbers input, for example, by the card purchaser. That is, upon initial activation of the card, the card user enters the telephone numbers desired to be accessible with the card. Note that to provide this capability, upon initial activation, the card user (e.g.

Subsequently, when the card is used to dial one of these numbers, a menu of the recorded options is provided to a card user, thereby allowing the card user to select any of the menu options for speed dialing.

Thus, for example, when a CPU 520 receives a menu response from a DSP 524, the CPU 520 accesses a corresponding resident data table entry and depending on the entry may:
  • the CPU 520 may require further data tables to be loaded from the hard disk 348. In such a case, the CPU 520 provides a request to the CPU 516 for the additional data and the data is requested and retrieved from the hard disk 348 as herein above discussed.
  • the CPU 520 may also request program elements and/or data tables to be downloaded from the hard disk 348 to a DSP 524 so that the next step in processing the service request can be perfor ed by this DSP 524. It is an aspect of the present invention that for substantially all service request processing done by a DSP 524 that there are generic program elements loaded at boot time that can continue processing the service request for subsequent steps by providing the DSP 524 with different data from the hard disk 348. That is, each DSP 524 is substantially data driven. However, for certain service requests, new program elements may be downloaded from the hard disk 348 to one or more DSP 524. In particular, there is a service request requiring the transfer of modem generated data, a set of different program elements are downloaded from the hard disk 348.
