I just reread every word mommy had to say and don't see this info. Are you guys also sharing info via PM or e-mail? In any case I think she is asking for a download that will pop up a message on her computer. Reread her first post, isn't that what she is asking about?

[KISS]

These are scenerios, that could be and would not work:

A line splitter at the wall and a coupler between the line splitter and the modem.

Two filters.

One dual filter using the wrong port.

Filter on the modem and not the phone.

Bb:

Post #6. Last sentence. DSL 10 words from the end.

[KISS]

Bb:

I'll agree. The subject and the content don't match for the first post. Later she states that she has to unplug one to use the other. Therefore, she is missing calls. Caller ID, is not free. The root of the problem which seems to be she can't be on the computer and using or hearing the phone ring while on line.

KISS you were right I did miss that one line but had my mind on we were answering somethiung she had not asked. I think AOPL offers the feature she needs but its not free. I think this is what she is looking for Call Alert! - Free Caller ID Software

I read, "she is missing calls while she is online". Seeing number on Computer was not an option for me, I wanted her to be able to go Online AND Full use of phone.
I currently think there are only 2 possibilities if she has DSL, Whole house splitter(doesn't make sense) or Bad or Wrong DSL Filter(The filter that plugs into the wall)this DSL splitter has a place to plug in phone and a place for computer.

[KISS]

I do believe if she buys one of these:
DSL Filters, Splitters and Phone Accessories Excelsus Technologies: : Z-330P2J ANSI Single-Line DSL Filter

Puts it into the jack on the wall.

Plugs the phone into the filtered side and the modem into the non-filtered side (I have no idea how they are labeled) she would be set. Agreeing with Strat.

A picture of what you have would be greatly appreciated.

Strat:
What's the possibility of having a whole house filter and a regular filter? I think the DSL modem would not work at all.

[Stratmando]

Kiss, I was Grasping for any posibility at this point, I have to agree with you that a DSL filter may solve this(with the current information).
Kiss, I never need to, and am curious of the Voltage on the DSL side, Were you saying it is 20 volts? I know the voltages for On/Off hook and Ringing on the Voice side. Thanks

[KISS]

This data sheet is a bit hard to digest: http://www.intersil.com/data/fn/fn7014.pdf

But it looks like it puts about 20 V p-p on the phone line. I was looking at another reference design and the answer was similar. It's just that the modems do better with +-12 Volt supplies internally. This would be about 7 V rms.

DSL can be provided naked, without dial tone. In that case it may not have any DC voltages associated with POTS service on it.

I saw the Plus and Minus for the Power, and figured OP amps(differential amps). 30 Years ago I used to Router out Fender Stratocasters, Install a dual Humbucker for the Lead pickup and Install home made circuit boards that used Op Amps for Amplification, Low, High, and Banpass filter, Extremely Low noise due to CMRR. I still think they offer the most gain and lowest noise, anything new better?

[KISS]

OP amps are not quite a differential amp. It takes 3 OP amps to make a differential amplifier. An Instrumentation Amplifier has differential inputs and differential outputs.
Audiophiles are very picky which OP amplifiers they use. (A-B) * (some big number) is not the same as (A-B) * ( a known number).

Op amps have gotten a whole lot better in 30 years.

My Audio amp is based on this design: Leach Amp Plans - Part 1
Which was describe in Audio Magazine in about 1976.

It boasts about 100 W/Ch with a 100 V/us slew rate and about a 0 to 1 Megahertz bandwidth, intentionally rolled off to 0.5 Hz to 44 KHz. Needless to say in 1980, about when I built mine, nothing came close. It boasts low Transient Intermodulation Distortion.
Almost all metal film resistors, 4 independent supplies of 50 volts and 40,000 uF of capacitance. It still rocks.

Comes close to a tube amp in listening tests. Tubes drive horns better and the Leach has better bass performance. Tube and classical go together and so does the Leach, dome tweeters and Folk music.

I always thought Op amps were Differential amps, that amplify the difference between the inverting and noninverting inputs, Thanks for the good info, In the seventy's I was building circuits to put in guitars, needed 2 9 volt batteries to power them(+9 and -9 volts),
I wanted to make them best I could, and I saw 2% Flame proof resistors, I just had to use them, The major manufacturers use 5%(gold band), I coul afford the extra dime. The resistances were not critical, but thought they sounded better anyway. Take Care

[KISS]

I know, getting lost in the technicalities:

Differential amplifier - Wikipedia, the free encyclopedia

Flame proof are typically metal oxide. Metal film and metal oxide definitely sound better than carbon composition resistors.

PS: Did you clean out your inbox yet?

When you say "sounds better" or do you mean "Sounds better".
Made room for some messages.
Hope mommy has her DSL working, and will post back with results. Later
