I had the same problem. Try adding the lines:

ModemSendFillOrder:     LSB2MSB
ModemRecvFillOrder:     MSB2LSB         # opposite of earlier models

to the end of your config.tty* file.  I found this worked on some MT5634ZDX
modems (which did class 2 even though customer support said they didn't).

The 56K modems appear to use a Rockwell chipset and one of our customers
had problems with them and went back to the MT2834ZDX (The MT2834ZDXb-u
appears to have the same chipset)

Here's a sample config file for the MT5634ZDX modems:
