A lot of these "cards" are not meant for you and I.  They are meant for
casual desktop users that would never put any amount of load on them.

About 6 years ago we needed some PCMCIA modem cards and bought 100 of
them from a vendor for $25/ea.  They started failing in the field.  When
calling they just could not sync up.  Only a reboot could fix the
problem.  What we learned was that a combination of heat and other
factors caused them to drift so much the timing was off.  We replaced
those in the field with Zoom 3075 at about $65/ea.  These modems were
not meant for our solution.  They were meant for casual laptop users
that needed to dial an ISP every so often.  I was expecting them to work
in a box that would stay up 24x7.  They couldn't handle it.  I wrote a
perl program that used a TLS-4 simulator and would dial the modem
constantly.  The failures were too much.  On the Zooms we would average
10 failures per 1000 calls.
