I'm sure that this has been discussed here before, so if you reply
to me, that would be fine.

Could someone give me a semi-technical explanation for those {{{{{{{{
which appear as interference at 1200 baud?  I am going round and round
with USWestComm about this.

About a month ago a new office was installed in Boulder (apparently a
DMS100 ? 3rd hand info) and ever since then I have had to re-call
numerous times to get a "clean" line.  It seems that discussions I
have seen in the past referred to something being "out-of-phase".
What exactly is out of phase?  Whose responsibility is it?  How would
be the best way to pursue this?  I have gone through several levels of
supervisors and still get "no satisfaction".  I am not the only one
with the problem, and I have pursued it from the "other" end (the
problems only happen when I call modems at the university where I
work).  Apparently the problem has been fixed for most people, but I
am served by a different central-office than most of my colleagues.

Here's some idea of the interaction from this end --

Calls 1-3: I have "data noise" (with description) on my line
response 1-3: your line checks out, must be your equipment
counter response: but I can call englewood, denver, elsewhere with no
    problems; I only get this when I call the university in boulder!

Call 4: Escalate, supervisor says he will check it out
call 5: no response so I call again this time another supervisor gives
	me a (next level) supervisor, this supervisor gives me a spiel
	about how above 300 baud they cannot guarantee anything
	without me acquiring a "conditioned line"
my response: well, let's see; a conditioned line from where to where?
answer: from your home to the central office.
resp: and don't I go through that same central office when I call
	denver, englewood, etc?
answer: yes
resp: then why do I need a conditioned line from my house to the
	central office when when I go via that path to denver,etc I
	have no problems?
answer: I don't know.  Well maybe you could turn down your bauds a
	little bit, say to a thousand or so and see if you still have
	the problem....
me: sheesh!

so HELP, can someone educate me a little bet so that I can better
communicate what the problem is AND perhaps point me to the sort of
department within the operating company which would understand the
problem and could do something about it?  I am primarily a software
person who knows enough about hardware to get my self in trouble, and
have worked at a company who was working on an integrated phone/data
network/workstation (but I was in the database group not the telecom
group) so I know some small amount of terminology related to this, but
not a lot, so too low level a description might lose me, but I don't
need a laymans explanation either.

thanks
