im curious as to what the line;
"Workaround used : V90Phase2Escape"
means...

this is the first time ive seen it... also the first time ive seen upload speeds faster than 24000bps... if even just briefly... has my isp finally implemented v.pcm upstream? or was that just a fluke (touch of luck?)

the full diagnostic is here;

No, there's no pcm upstream - V.34, provides for rates up to 33.6kbps. There isn't any successful implementation of V.92-pcm upstream anywhere, and there's not likely to be.

I don't know what the 'workaround used' line really means, but if you search that term, you'll find other postings of user diags with it - and some of those connections are V.34 both ways.

Aloha! Richard.
