The subject method for integrating data and non-coded information (NCI) consists in systematically inserting zeroes during NCI periods at regular 9-bit boundaries. NCI and data periods are delimited by 11-bit flags. Systematic zero insertions do not take place during the data periods, wherein asynchronous zero insertions take place after five consecutive ones. A technique to mix data and NCI e.g., non-compressed voice, without any transmission delay distortion consists in delimiting data and NCI periods by means of flags, using a zero-insertion/deletion technique within data portions and avoiding flag simulations within NCI periods. This last requirement implies that NCI patterns corresponding to the delimitation flag are modified.
