REAL-TIME TMS320C25 IMPLEMENTATION OF THE SIGNALLING CONVERSION IN THE 60-CHANNEL PCM/ADPCM TRANSCODER EQUIPMENT

摘要

This paper proposes the real-time TMS320C25 implementation of the signalling conversion in the 60-channel PCM/ADPCM transcoder equipment with two or less signalling bits per channel in the channel associated signalling considered. It is shown that this proposed conversion scheme between PCM signalling and ADPCM signalling works well.
