I am using a 1200 baud modem over a voice grade line and
am getting a LOT of static.  At first the line was completely
unusable, but a guy came out and adjusted the "level" (he said it
was "hot" at my end - the origninate end) and now I'm down to
an error about every 10-15 seconds.  

I've tried to get AT&T to look at it, but they say the line is
up to "voice-grade" specs and refuse to do anything more (I was
going to order a "data-grade" line but was told it would take 6
months to install).

Is there anything I can do myself.  What does adjusting the "level"
mean and can I do it myself ?  I have the feeling that another 
adjustment might be all it would take to fix the problem. One anomaly 
is that while I get almost continual errors in transmission from 
the mainframe to my terminal, there are absolutely no errors 
in the other direction (I dial up to the mainframe so the
frequency is higher coming back, but it's hard to believe that
the difference is just the difference in frequency - or is it ?)

If there are answers to these questions in a book, please point
me towards it.

Thanks,
