To be perfectly frank, I don't know.  However, some phone line
conditions fluctuate enough to initially 'fool' the modem into thinking
that the line can support a higher carrier speed than it actually can.
Conditions may change in such a manner as to throw the modem for a loop
with renegotiations, etc. as to cause an eventual lost carrier.
This might be what is happening in your case. Forcing the modem to a
lower initial carrier speed often solves the problem.
