-
- I have a US Robotics 28.8, which will ,after ti is connected, report the
- Frequency Response Characteristics on a phoneline by giving it the ATY11
- command.
-
- I can dial in to all of our pops, and the Frequency Response numbers will
- be 20dB and up, with the high numbers in the beginning and end as one
- would expect. Except for one POP.
-
- In this POP, the numbers are in the 13-14 range (ie. at least 6dB lower),
- and in this POP it is nearly impossible to get connected at any decent
- speed.
-
- And now comes the weirdest part: When I dial into this pop Long DIstance,
- the numbers are back in the 20+ range, and everything works fine and
- Dandy.
-
- We have swapped out working equipment, etc etc etc, and of course nothing
- changed. We suspect the phonecompany has made an 'improvement' that has
- caused this problem to start occuring. Has anyone seen something like
- this before? If so, what was the problem and how was it fixed?
-
- Or, does anyone know a place to get test-equipment to actually test the
- wuality of dialup telephone connections?
-
- Any help greatly appreicated, we are stomped!
