Abstract:

REPORT DESCRIBES A DIGITAL DATA RATE REDUCTION TECHNIQUE DESIGNATED AS Time Assignment Speech Interpolation TASI and the corresponding development of an experimental digital TASI equipment. The Digital TASI technique was used to demonstrate a reduction in the transmission rate for a digital multi-channel communications system. The TASI system takes advantage of the idle or silent periods on each one-way channel to interpolate additional conversations. Thus, many incoming channels can be connected into one outgoing channel in a time division manner. The input signal for the experimental TASI equipment is a 48 voice channel PCMTDM signal using standard 6 bit per sample PCM. The output is 19 channels of 6 bit PCM plus 1 13 channels for overhead information. Author
