Abstract

PURPOSE: To reduce the size of a control circuit and the quantity of distributing wires and make it easy to alter the connection of concentrated lines by making the concentrated-line multiplexing constitution which can divide the digit pulse trains of a coding burst signal, put the divided pulses on the plural multiplexing high- ways and then return them to the original coding digit pulse trains on the output side.
CONSTITUTION: The upper 4 bits and the lower 4 bits of paralleled circuits 61, 62 and 63 are connected to high-ways 21 and 22 respectively and 24Ch of pulse count modulation (PCM) is octo-multiplexed. When the addresses of phase holding memory 48 of control circuit 17 are read out sequentially and decoded, the coding digit pulses corresponding to signal channel coding 31 to 3n are supplied to the paralleled circuit sequentially. The pulse trains transmitted in parallel on the high ways pass through gates 23 to 26, which are opened/closed by gate 27 and return to the original coding digit pulse trains. When the logic "OR" of the output terminal of paralleled circuit is altered, the number of multiplexing high-ways can be changed.
