Default Line quality

I just had a land line installed and there is some static on the line.

I am trying to get hyper terminal to send an AT%Q command so I can get some reading of the line quality.

Anyone know of an answer or another method ?

Thanks.

Don't you need a dial-up MoDem installed before you can use AT commands?
(Though I never heard of %Q for line quality. Is it Q for quiet?)

For dialup, you connect the modem to the dialup modem
pool, and run it long enough to train up the modem and
evaluate the frequency bins. So you must use a dialing
string, hear the "tones" coming from the modem speaker,
and connect until the ISP delivers a prompt. Wait
60 seconds (or, whatever period the ISP leaves the
unauthenticated session connected). Then, drop the connection,
and use a Hayes AT command to dump the table.

In this example, they connect to the modem pool for
15 to 60 seconds. Then disconnect. Then, manually
type an AT command.

http://www.modemhelp.net/linenoise/usr/usr.shtml

I had a worked example of this (run on my USR dialup modem),
but can't seem to find any evidence of it. It gives
some info per frequency bin, and the site I got the
info from, showed some typical curves. The ATI6 command
in the above example, is a summary of conditions,
of some sort. But it should be a summary of the
last "session", that 15 to 60 seconds of "training"
the modem got. Some other command gives the values
for the bins. But I can't even find my Hayes command
set document. I've got one somewhere, for that modem.
Just can't seem to find it.

Thanks.

I don't have an ISP, I use a wireless receiver that uses my apt. account for internet.

I know that I was using hyper terminal at one time with AT commands.

You don't they they broke it ? Just kidding.

My telco is coming out in 2 weeks to check my line.

I can fax fine, but would like some proof of the poor line quality.

I have already check the internal wiring.

The telco gives instruction on how to verify if the static is internal or external by plugging into the outside box.

When I checked, it was inaccessible.

In addition to phone wires, there were cable lines going into the box, so no telling "what's in that box."

There may be a lizard or gecko remains in there partially shorting out the phone lines. :-)

When squirrels in my "hood" venture on to the power lines, a transformer trips.

Take care.

For ADSL, there is "DMT". This is the equivalent of
one of those Hayes AT tests. You can only do this sort
of thing, right at the modem.

http://www.kitz.co.uk/routers/DMTv8.htm

With ADSL, it's the same kind of concept as dialup, only the signals
are arranged above voice band. There are more frequency bins.
(Which is why microfilters are used for a typical home installation,
to separate ADSL high frequency noises, from the voice band for a
POTS phone.)

This picture shows the frequency bins, as read out
of an ADSL modem interface. The modem records these in
real time, but it took a third party developer to write
a nice piece of software so we could actually look at them.
The modem makers won't help us with this stuff. Some modem
firmware upgrades, even break this function.

http://www.kitz.co.uk/routers/images/DMT4.gif

*******

When it comes to static, hum, clicks or other impairments,
you'd be surprised how many times it is actually the
house wiring. Back home, our problem was just "too many
goofy devices" )exceeded loading limit) connected to the
phone wiring (including a strobe light box, that flashed
when the phone would ring, for the basement area). And no,
I didn't add that crap. Other family members did.

In my own home, corrosion on the baseboard RJ-11 connector
boxes, resulted in my old dialup modem dropping to
only 33Kbit/sec operation. Disconnecting the house internal
wires, at the demarcation point, and running a brand new cable
and box to the upstairs, got the dialup modem back to 46K again
(of 53K max).

A friend had a similar issue, and for him, it was where the
cable went through the foundation of his house.

Our telco here, occasionally evaluates line quality. They set
up a table and patio umbrella a couple weeks ago, while
running tests from the CO to our remote box. They don't test
all that often, but we just had it done - they need high quality
lines for their expensive "bundled service packages" - they weren't
doing this to make my analog phone work better :-( They only
do the work, to help them make more money off premium services.

Hear, hear. For me it was a 'branch' line. Remove branch, quiet phone.
Wires were solid, 'lab quality' bench wires, inside house that sounded
like someone was wadding up a newspaper. No idea the cause of
deterioration, but telephone company wanted to charge for problem being
inside. Luckily the telephone compnay repairman was kind enough to place
total blame on exteriror wiring in a cable out in the street. rerouting
there AND removing the branch made the line absolutely DEAD quiet.

I figured out how to get a fairly good idea of my line quality using hyper terminal. My telco is taking their time coming to check out the line.

I send up a wav file recorded by Audacity of my modem dialing, if you want to hear it, it's at http://d01.megashares.com/index.php?d01=OSL4v7E

There are specs that the telco MUST meet. Demand that those be checked, i
the interim, find out what they are, if they don't meet DEMAND that you
don't pay for when they don't meet spec. Usually, in the US you are not
liable for the cost of a service you did not receive.

I already told them that I won't consider my service as being started until it actually works.

For 40 + years, I had AT#T with almost no problems, now I have Veri^o@.

All of my former residences had accessible outside phone interfaces.

My apartment does not and it has a bunch of cables coming into the phone box as well.

No telling what's in the box, might be a bunch of dead geckos, etc. that got electrocuted. :-)

I should not have to get the FCC and Texas Utility Commission involved.

I did not have to sign up from USA.
Zil may be in a country other than the USA though.

If you convert a WAV file to MP3, 128 bit rate, there is
a 10:1 compression. 6 MB file becomes 0.6 MB.

I'm intereted in hearing the .wav file, but that website doesn't work for
me and being on dial up 6MB is a bit daunting anyway.

Does the sound change, as in sweep frequencies, over time; or is it
constant? If it's weird, but constant, with approximately 1 second's worth
it can be 'reconstituted.

If the sound is NOT sweeping, could you send approx 1 second of the sound
as attachment to me?
