ABSTRACT:
A known system having a transceiver device (such as a radiotelephone, or walkie-talkie) for the transmission and reception of speech information via a speech channel in a wireless manner is only able to transmit and receive short data messages via an organization channel, switching means present in the transceiver device determining the channel with which the transceiver device is coupled through. As a result of expanding the system with a modulator/demodulator device, it can transmit and receive large quantities of data via the speech channel, an increased efficiency of the system being obtained by triggering the switching means from the modulator/demodulator device.
