Abstract
The PBX system includes an analog to digital, and digital to analog, (A/D) conversion where the sample size and the sample rate are selectively adjustable. The A/D structure includes registers which hold values indicating the sample size and the sample rate for the conversion. When the A/D structure is configured, the A/D structure reads the values in the register and configures itself to the sample rate and sample size indicated by the registers. When the sample size and sample rate is to be changed, the values in the registers are changed and the A/D structure is reconfigured.
