it means v.34 at 2400 bps
i have a dataplex dpx-224 whic sings very accurate v.22 bis tones .. my
courier sings very accurate (i believe) v.8 and v.34 tones eventually the
dataplex connects with v.34 at 2400 .. this is not what the recomendations
say should happen. also v.34 at 2400 is far less reliable that v.22 bis at
2400.
the courier even when locked at 2400 doesn't sing the v.22 bis tones at the
incoming modems
v.32 bis is a differnet protocol and not that far removed from v.22 bis in
basic structure .. it also had the required 'technicals' to swithch the
protocols .. i am asking if the same exists in the v.34 and now v.90 because
based on my experience this seems to not be the case.
you are correct in your assumptions and short of spending some $30k on buying
a hp spectrum analyser i am not going to find out directly what is going on,
but using the ears god gave me i can detect serious protocol violations.
this is why i am interested .. also i have several disabled people on my
system that cannot afford to upgrade thier hardware, they use the v.22 bis
modems i gave them for thier ibm xt clones on which they run rbcomm (thank
you mr r. brown). i too am a disabled person but i used to be a systems
analyst in a previous life and had garbage bags of hardware left over when i
was forecably retired from my working career by a part of my brain that
decided to go out to lunch and not come back .. we don't where it went, but
we are still looking for it.
thank you for your post, it is most appreciated.
ps, sorry if i sounded a little sarcastic .. this is how i am on a good day,
on the bad days i don't post, well i try to say as little as is possible if i
really need the information. i am not very well socialised, yet, it is only 7
years since i had a complete brain shutdown.
