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.
