Trouble with EQMs tho is that they are AT the particular speed in use, they ARENT a measure of the line itself but essentially a measure of the error rate at the particular speed, measuring the error in the real constellation bits compared with where they should be in the constellation. PE> I was thinking that this might be a substitute for the old occurrence PE> of a failed connect to the Spirit, but instead, the Netcomm succeeds PE> in stepping down to a more reasonable speed rather than failing. I doubt it. It looks more like a massive brain fart given I never did get anything remotely like that with any other system I ever called at a high freq for mail. PE> Or would you expect V32bis modems to always connect at 14400? Certainly not at 7200, thats extremely low. I would expect that if the line at your end or mine was marginal, we would occasionally see a 12000 connect and in fact I did with one particular line with the City BBS which I called daily for mail for a long time. He is on one of the most decrepit exchanges in Sydney apparently and doesnt have his lines in a rotary group, and you could see one line being a bit down performance wise. It always connected fine, sometimes at 12000 and normally did manage to fall forward up to 14400 thru the session. Occasionally it connected at 14400 and fell back to 12000 for a bit and back up to 14400 too. And this one is unlikely to be due to the voice call dialing coz once the modems have fallen forward up to 14400, the thruput is fine. @EOT: ---* Origin: afswlw rjfilepwq (3:711/934.2) SEEN-BY: 711/934 @PATH: 711/934 |
