3.2 73M1x22 Data Module
The 73M1x22 Data Module is responsible for providing the proper translation of data samples from the
73M1x22 (as transferred over the MAFE interface and through the 73M1x22 Hardware Interface module)
into a usable form for the User Application Module. Different applications may require different variations
of the 72M1x22 Data Module (i.e. high or low speed fax or modem).
