Figure 1-7 shows an HDSL data modem application where a CPU processor  
delivers PCM data directly to the RS8953B. Alternately, a multichannel  
communications controller such as the Bt8071A can be used to manage the  
transfer of data between the CPU and PCM channel through a local shared  
memory.
