Sounds like it might be the same problem biting Dave Hatch
currently. Do you know what phone exchange technology and
stuff like fibre to the pillar you have on your line ?

JL> Symptoms show a narrowing of line bandwidth for some obscure reason.

Are you saying you have MEASURED a reduction in bandwidth or you think
the symptoms indicate that ?  V34 is supposed to auto compensate for that.

I'm not convinced, V34 is a hell of a lot more practical way to handle
that that a half duplex protocol. The only exception is where the session
has some massive problem with echo cancellation characteristics varying,
in which case a half duplex protocol has real advantages.

JL> However since Paul's M34F doesn't implement half-duplex

If you really are just seeing a bandwidth
reduction, full duplex V34 should handle it fine.
