PE> Make that one of Bill's calls got 26400 too. This
PE> 26400 is a pretty popular fellow, any reason why?

BG> Only the initial connect.  It immediately shifted up to 28800, the
BG> reason being that V.34 is monitoring the line's bandwidth continuously.

RS> I dont believe that the lines really do actually

BG> I've dropped into command mode on several occasions while

RS> Sure, thats why the V34 protocol allows for quick rate

RS> From memory he is on a rather geriatric crossbar
RS> exchange, so its not surprising that its variable.

BG> I've lost the thread here.  Who were we discussing?

Your observation that the line frequency response varys thru a session.
That was in the quoting, you only kept my two line para immediately above.

RS> Doesnt explain 2400 sessions tho, particularly when I have not
RS> EVER seen it fall back from 14400 in the years I have been calling.
RS> Atleast one of the City BBS lines does that quite often when I call.

BG> Sure, and I still believe that Paul has problems at his end.

Cant see a SHRED of evidence to substantiate that belief.

BG> Who knows, maybe his serial card was also zapped.

Its certainly possible, but getting rather desperate, particularly when the
mindless retrain behaviour is seen with every other USR VE I have called. It
will be interesting to see what happens with other Viper calls to USR VEs too.

AND its a tad hard to credit that a serial card fault would produce THOSE
two particular symptoms too. Those are negotiation BETWEEN the modems.

BG> Hard to say when I'm 1000km away.

Decent engineering has to be able to resolve those too.
