Abstract
PURPOSE:To transfer a secured operation control command from a distribution stage control part to a line concentration controller by sending repeatedly information, consisting of more than one bit, in series by more than one frame at a time to specific bit positions in each frame of a PCM circuit which couples the line concentration stage with each channel device of the distribution stage. CONSTITUTION:An operation control command for a line concentration stage controller transmitted from central processor CP at a distribution stage is sent to a PCM circuit, extending to line concentration channel device LCM, via a distribution stage channel device by using a specific bit in specific time slot TS16 of the PCM circuit as operation control bit SC for the line concentration stage controller and then by varying the operation control bit from zero to one corresponding to control items of six bits SC0-SC5 in one multiple frame consisting of six frames.
