- I've been busy with things for awhile and haven't been keeping up with the
- newsgroup for about a week. Anyways, USR modems have the same pausing
- problems on the phone lines here that they do with a direct connection,
- but usually not *quite* as extreme. I guess Orlando phone lines are not
- attenuated enough for them. The reported receive level is usually the
- same or only 1dB lower than with a direct connection. Most other modems
- don't seem to have a problem with it. These lines do *NOT* have
- crosstalk, like my apartment does. Also, not all USR users calling here
- have this problem, only about 1/4 or 1/3. This amount has increased when
- we got more lines, so the switch the lines go thru may have changed, but
- other modems are connecting at higher speeds than they were before (more
- 28.8's and less 21.6's and 24k's).
-
- We tried adding a resistor on the line of a USR that was having this
- problem, as suggested by dhaire, and the pauses almost completely went
- away, and the modem had higher transfer rates as well, so I think it
- actually is a problem with the USR's handling of unattenuated lines.
