Abstract: A method and system of providing digital communications over frequencies concurrently utilized for analog communications. In one embodiment, the method (400) includes the step of establishing (410) a digital channel including two or more analog channels that are concurrently used to provide analog communications. A spread spectrum digital waveform is generated (420) having its energy spread throughout the bandwidth of the digital channel. The spread spectrum digital waveform is modulated (430) to include information to be communicated digitally and transmitted (440) over the digital channel. The transmitted modulated spread spectrum digital waveform is received (450) and demodulated (460) to obtain the information.

Abstract: Methods and systems in which vocabulary recognition enables routing of analog transmissions over digital networks are provided. In one embodiment, a method (200) of delivering analog transmissions over a digital network includes receiving (208) an analog transmission including source identifying vocabulary associated with a source of the transmission, converting (210) the received analog transmission to a digitized transmission, analyzing (214) the digitized transmission to obtain the source identifying vocabulary therefrom, retrieving (220) routing information based on the source identifying vocabulary, buffering (212) the digitized transmission during the analyzing and retrieving steps, associating (222) the routing information with the buffered digitized transmission, and delivering (224) the buffered digitized transmission over the digital network according to the routing information associated therewith.
