    摘要： A wireless telephone (302) digitizes the voice of the user in response to the depression of a push-to-talk button (110), either physical or virtual. It sends the digitized voice, in data mode, to a base station (308). The base station places the data, through the Internet, or an Intranet or Extranet, on a server (312). Other wireless phones (304)-(306) recover the data from the server through the same (308) or different (310) base station, through the Internet, Intranet, or Extranet, and convert the data back to digitized voice. The base stations transmit the digitized voice to other wireless telephones (306), which convert them back to voice in response to the recognition of voice frames on the data channel by the CODEC manager software. Networked computers (314) may be configured to emulate a combined base station and wireless telephone. The server can dynamically designate any wireless telephone (or landline emulation) as the broadcaster, and can dynamically configure any set of telephones/emulations as the receivers of the broadcast.

    摘要： System and method for minimizing data bottlenecks in Low Data Rate Networks (LDRNs) that communicate facsimile transmissions. An LDRN is a facsimile network having a transmission data rate less than the data rate of the FAX machines serviced by the network. The system and method can be implemented in any type of LDRN, including analog and digital wired LDRNs, as well as analog and digital wireless (e.g., cellular) LDRNs. The system and method involve processing the facsimile transmissions in order to make the data rates of the LDRN and the FAX machines compatible, thereby minimizing any potential facsimile data bottlenecks that may occur in the LDRN due to its slower data rate. Lines of data are transferred by the LDRN only when the amount of data they contain is less than or equal to a line threshold value, which is adjusted according to the amount of data bottleneck experienced by the LDRN.
