I have used Group 3 Fax on M44 type T1 service.  It works, but the fax
usually drops to a lower speed.

Not recommended for lines with a lot of fax traffic, especially fine
or long faxes.  If your savings on the voice services are great
enough, consider putting your fax machines on direct outside lines
serviced by the regular 10XXX carriers.

In summary: M44 is fine for voice, but poor for data/fax.

Timeplex has done considerable research on this (so has Newbridge) and
can give you more info.
