PE> And I don't know how you know what transmit levels the PE> Courier was putting out compared to the Netcomm either. RS> Its shown in the session stats, RS> Recv/Xmit Level (-dBm) 26.6/12.9 BG> FWIW, the second figure above is the USR's Tx level, while BG> the first is the NetComm's Tx level with the total line losses BG> included (as seen by the USR). Ergo, if you know the M34F is BG> transmitting at -11dBm, you also know that there is an overall loss BG> between the modems of 15.6dB. Well, thats the theory anyway. I think that Recv figure is just as bogus when its not a USR as the db figures on the line probe table. The evidence for that is that when its a USR on the other end, and we can see what IT claims its transmitting at, and then calculate the line loss, we get a DIFFERENT line loss, 6db different in fact. Something extremely fishy going on there somewhere. Corse we dont actually KNOW that the Netcon is putting out -11dbm when it claims it is, but its unlikely to be 6db out, thats a hell of a lot. BG> And THAT would be in excess of Telstra's own BG> maximum accepted level between subscribers... But NOT with a USR/USR pair, so it cant really be true. @EOT: ---* Origin: afswlw rjfilepwq (3:711/934.2) SEEN-BY: 711/934 |
