Is the SC144HI obsolete? Is the MT5600SMI-32 for replacement of the SC144H1 and is it pin to pin compatible with the SC144H1?
The DSP chip on the SC series socket modems is no longer available and is being replaced by the chip set vendor with a new model. The MT5600SMI series socket modems will be drop in replacements for the SC series parts. Yes, the MT5600SMI-32 is the replacement for the SC144H1.
