線。 In a voice meeting telephone line for mutual communication between a plurality of N stations connected to a loop-type transmission line, one time slot of the loop-type transmission line is used as a line, and data on the transmission line is multiplexed into N channels for each station. a multiplexing/demultiplexing section that separates data other than the own station from the source and inserts the own station data; a digital addition section that digitally adds the data for the separated (N-1) channels; and the added data. What is claimed is: 1. A voice meeting telephone line in a loop-type transmission line, characterized in that it is provided with an encoding section that performs digital-to-analog conversion of the signal and analog-to-digital conversion of the analog signal from the connected terminal.
