Abstract: A method of invoking and canceling voice and data service between a mobile unit and a base station. Using a standard telephone system, the connection for a voice service and a data service is the same. With the introduction of the digital wireless link, the voice connection and the data connection are different. Therefore new dialing commands which indicate the intent of the connection are created. These commands can also be used to designate the intent of the call from a mobile unit capable of data and voice service but not capable of simultaneous voice and data service. They can also be used to invoke simultaneous voice and data services.

Abstract: In a method for minimizing a data bottleneck in a Low Data Rate Network (LDRN) (34), i.e. a facsimile network having a transmission rate less than the data rate of the facsimile machines serviced by the network, the LDRN (34) has a one-dimensional image data format and a two-dimensional image data format. The method comprises 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. In the method, a first facsimile (FAX) machine (12) is set to the one-dimensional image data format; a data stream encoded in the one-dimensional image data format is sent (32) from the first FAX machine (12) to a first side of the LDRN (34); the data stream sent is uncompressed, and the uncompressed data stream is re-encoded into the two-dimensional image data format; the re-encoded data stream is transmitted from the first side of the LDRN (34) to a second side of the LDRN (34); the transmitted data stream is second uncompressed; the second uncompressed data stream is second re-encoded into the one-dimensional image data format; and the re-encoded data stream is second sent (36) from the second side of the LDRN (34) to a second FAX machine (16).
