General Description
The Multichannel Programmable Codec Chip Set is
comprised of the T8531 16-channel line card signal
processor and one or two custom T8532 octal A/D
and D/A converters. A ROM-coded tone plant is
included on the signal processor. Together these
devices achieve a highly integrated and highly pro-
grammable multichannel voice codec solution.
Software is provided to compute the gain and filter
coefficients required to program the codec.
