Voice and data multiplexer system
First Claim
1. A system in which two stations are respectively provided with telephones and data terminal means such that a voice and data are multiplexed for communication between said two stations, each said station comprising:
- means for converting voice signals inputted from said telephone into a plurality of kinds of predetermined voice parameters;
means connected to said converting means for outputting a signal representing a transmission mode determined on the basis of a predetermined parameter of said voice signals;
means for extracting from data to be transmitted from said data terminal data having a length according to said transmission mode signal;
means connected to said converting means for selecting at least one of said plurality of voice parameters according to said transmission mode signal; and
means connected to said extracting means and said selecting means for editing a mode indicator indicating said transmission mode, the selected voice parameter, and the extracted data into a transmission block format accordion to said transmission mode signal.

Abstract
A system in which two stations are respectively provided with telephones and data terminals such that a voice and data are multiplexed for communication between the two stations. Each station has a circuit to convert voice signals inputted from the telephone into a plurality of kinds of predetermined voice parameters, a circuit to determine a transmission mode depending on a predetermined parameter of the voice signals, a circuit to extract data having a length corresponding to the transmission mode from data to be transmitted from the data terminal, a circuit to select one of the plurality of voice parameters depending on the transmission mode, and a unit to edit a mode indicator indicating the transmission mode, the selected voice parameter, and the extracted data into a transmission block format corresponding to the transmission mode. The transmission block includes only voice information containing all voice parameters in the first mode; voice information and data information in the second mode, and voice information containing the minimum voice parameters and data information in the third mode.
