Abstract
PURPOSE:To contrive the increase of the line number in response to the frequency of communication by applying high efficiency coding in response to the decision of propriety of a coding/decoding function and applying the channel assignment so as to send the result together with a time slot assignment signal and alarm information of decoding function. CONSTITUTION:A channel assignment circuit 9 uses a time slot assignment signal so as to apply proper arrangement and conversion to a coded data from a PCM/ADPCM conversion circuit 6 of each channel in the operating state, or a uncoded data from PCM signal input terminals 1, 2 and a signaling from a signaling extraction circuit 3. Moreover, a time slot assignment signal insertion circuit 10 inserts the time slot assignment signal from an assignment signal generating circuit 8 in a generated data string. Moreover, a reception side alarm information insertion circuit 11 inserts fault detection information outputted from the fault detection circuit 18 into a data string outputted from a time slot assignment signal insertion circuit 10. Thus, the increase in the line number is attained in term of frequent communication.
