Abstract:
In a wireless digital communications system receiving a modulated wireless signal from a digital telephone, the digital telephone having a subscriber telephone number and a vocoder for compression of voice signals to generate digital vocoder voice samples in a vocoder protocol specifically adapted for the wireless digital communications system, the modulated wireless signal carrying an encoded form of the digital vocoder voice samples as encoded, digital voice samples for a destination telephone number, a system comprising:a first wireless transceiver having a demodulator demodulating the received modulated wireless signal and outputting a first data stream carrying the encoded, digital voice samples; a decoder decoding the encoded, digital voice samples and in response outputting said digital vocoder voice samples from the first data stream in said vocoder protocol; and a gateway interface sending and receiving packet data via a packet switched network, the gateway interface having a packet assembler/disassembler receiving said digital vocoder voice samples in the vocoder protocol, the packet assembler/disassembler packetizing the received digital vocoder voice samples into data packets having a destination address corresponding to said destination telephone number, the gateway interface outputting said data packets onto the packet switched network for reception by a network node corresponding to said destination address.
