ABSTRACT:
In a TASI system using dynamic subband allocation and BCPCM (Block Companded PCM), losses due to freeze-out or delay are avoided by use of a multi-rate macro-frame format, wherein switching to a lower rate (24, 16, or 8 Kbs) for one or more of the input channels is accommodated by simply dropping one or more sections of each signal frame, since the lower rate bits are distributed over the entire frame.
