Hi Michael,
Yes, I understand that. 
But, (isn't there always one of them ?), why should I have to *force* a lower 
speed connection. Why is this not negotiated in the negotiation period ??
CM>>2. I can't seem to get the ATS86? to work properly. Binkley has an

Agreed, however I am after enough info to be able to use the sum of it to get 
the line improved so that it is at least consistant. 
I will contact the Australian Hayes support on Monday.
