Fax, DSL, Windows XP question

[Linkmeister]

Re: Fax, DSL, Windows XP question

Helen has my setup described accurately.

What passes through this cable is whenever he wants to send a fax (I suppose recieve an incoming fax as well).

Or, potentially, my dial-up access in case of DSL failure. I think.

Re: Fax, DSL, Windows XP question

No, you don't plug the fax to the DSL modem.

In Linkmeister's setup where he has a three way splitter connected to the telephone jack. From that splitter the following lines are connected to it:

1. DSL modem (no DSL filter used)
2. telephone (DSL filter)
3. line to the modem on the PC (DSL filter)

In essence there will be two lines running into his PC. One cable runs from the DSL modem to the Ethernet port on his computer. If one looks at the end of this cable you would notice that it has 8 connectors to it. This cable all of the networking traffic goes through it.

The second cable runs between the wall splitter (position #3) to the computer's dial up modem port. The ends of this cable would have 4 connectors to it. What passes through this cable is whenever he wants to send a fax (I suppose recieve an incoming fax as well).

Re: Fax, DSL, Windows XP question

On some PCI fax cards, there is a line in and a TEL RJ-11 jacks (two jacks). The line in provides the connection to the TELCO while the TEL jack gives the fax user another jack to plug their analog phone into. If you have jacks like that simply plug the fax card into the DSL filter going to your wall jack and the DSL modem into the TEL jack on your fax card. That jack is simply an extension RJ-11 and functions like the second split on a two-way splitter.

I'm trying to make a picture in my brain from this description, and it's not working (the picture, not my brain).

If the wall jack leads to a DSL filter, and the DSL filter is plugged into the fax card, and the DSL modem is plugged into the fax card's TEL jack, then wouldn't the DSL filter keep the DSL freqs from reaching the DSL modem?

Re: Fax, DSL, Windows XP question

Not to be confused with this Radio Shack product. BTW even the web designer for RS made this mistake as this product is the RJ-14 to RJ-11 adapter.

The one you showed is okay as it's a simple three way adapter

Well, I'm holding the product in its package, and the product number is 279-435, and the name is 3-way modular jack, so I think I'm ok.

You know what's annoying? The price on the web is $2 cheaper than it was at Pearlridge.

Addendum: I went ahead and replaced the old splitter with the new one. I've got dial tones all three places and the fax I wanted to send apparently made it through to Senator Inouye's local office.

Good. Although that wall jack now looks like a picture you see in all electrical installation diagrams that says "Don't do this!"

Well, Craig, here's what I bought. It looks like I can do what I want, but if you think otherwise...

Re: Fax, DSL, Windows XP question

And don't forget a DSL filter.

If you need to send out a fax in the meantime, you can use this free site to push it out over the web or via e-mail. Just remember that when borrowing someone else's fax server, your data becomes theirs for the reading.

That's an interesting service. Thanks.

I have about six extra DSL filters; not a problem.

Re: Fax, DSL, Windows XP question

Whoa there partner...make sure that three way is in fact a three way splitter.

Sometimes what looks like a three way isn't.

Telephone jacks can be configured for either two or single line. The red/green (two center connections) is the tip/ring connections for line one or a single line. If the jack is configured for single line use then it's called an RJ-11 jack.

If you have two lines on that jack where not only are you using the red/green wires, but also the two outer connections (yellow/black) then that jack is called an RJ-14.

On some two line phones they use either two single RJ-11 jacks or a single RJ-14 connection on the back of the phone If the wall jack is configured as an RJ-14 jack then a four-connector telephone cord is all that's necessary if the phone has a single RJ-14 jack it. If it has however two RJ-11 jacks (each one labelled L1 and L2) then you need to split that RJ-14 wall jack into two separate RJ-11 outlets and run two telephone cords from each split to the L1 and L2 jacks on the phone.

On what looks like a three-way telephone splitter is actually three jacks lablled L1, L2 and L1+L2 for your three jacks. Basically this splitter converts an RJ-14 wall jack into two RJ-11 and a single RJ-14 jacks.

If you have a single-line phone and use an RJ-11 outlet, it'll give you dial tone on the jacks labelled L1 and L1+L2 but you will have a dead phone if you plug it into the splitter jack labelled L2.

Basically that three way splitter is actually an RJ-14 converter so be aware when you go to the store and grab what "looks like" a three way splitter.

Re: Fax, DSL, Windows XP question

At the wall I've got a two-jack splitter, one for the DSL modem and one for my main phone. I just picked up a three-jack splitter to replace it, and I'm gonna try plugging the PC internal modem into the third jack on the splitter and see what that does. Lord knows I've got enough extra phone wire to wrap around the house twice.

Re: Fax, DSL, Windows XP question

I haven't used my fax in a while, but I run XP and was able to use Windows Fax. At the telephone jack, I inserted a simple two-way phone line splitter from Longs. Now I have two jacks. Jack 1 goes directly to my DSL modem. Jack 2 has a DSL line filter connected then is connected to the fax port in the back of my computer.

Re: Windows XP question

The short story is that the electronics involved in Ethernet communications which DSL uses makes use of direct current (DC) signals, like 0 or 1, 0 volts or +5 volts.

Electronics involved in standard telephone communications makes use of alternating current (AC) signals, like -15 volts to 0 volts to 15 volts (and I am guessing on the voltage limits). Also the electronics involved do not pass DC signals so one needs to have a device called a modulator-demodulator that will convert those signals back and forth. The modulator-demodulator also goes by the name of modem.

Re: Windows XP question

I found an article from a MS writer elsewhere on the MS site, and it clearly states "you can't fax using DSL." No explanation as to why, but thinking about it, I'll bet it has something to do with "handshake" protocols between fax modems.
