faxing ???

[Mathematics!]

Ok , I have this old Dell Dimension 8100 System from around 2003.
It has a modem card in it BCM V.92 I believe this is a soft modem that would be used for dialup back in the day. But I have Windows XP professional running on it and I just realized that their is fax software that I have just installed using the windows install components with the OS CD.

What I want to know is if I run a telephone line from the BCM V.92 modem to one of my telephone jacks and use the software to send a fax will it work without any additional hardware? In theory it should unless their is a special modem you need to send the fax down the telephone line?

I am aware that you cann't use the phone when sending a fax unless you get a second line and dedicate the fax to that line seperately.

The software say's it allows you to send and recieve fax thru your computer. The only thing that I am shake on is if I need a different modem or hardware addons to make it send the data modulated correctly on the wire. I hope not because I am not willing to buy it.

Seems that it should work
here is the link to how to use the software it is pretty straight forward.

I want to be positive all this will work before I start string telephone wire thru the walls ...etc etc.
Not any good info is on the net that talks about how these modems work do they modulate analog or digitally like PWM or analog FM or analog AM , what carry frequency ,...etc etc

Also just curious what the protocal for sending fax data down a phone line would be??

I know caller id info is send between the first/second 90volts ac 20 hz ring superimpose digitally onto the analog 20 hz wave using PWM.

I am assuming something similar with fax but maybe a little more complicated.

Realistically I am think dialup modems are just faxing the internet data over to you.
Maybe
Thanks for the help.
I will stop rambleing.

this link is almost convincing me that it will work "it say's V.92 data/fax/ on the page half way down.

I've never used the Windows fax program but I see no reason why it wouldn't work as long as the modem is a data/fax model (and most are).

Fax transmission uses the CCITT Group3 fax protocol which specifies both the coding scheme and the transmission protocol. Unfortunately CCITT charge for copies of their standards so you won't find it on line but there are numerous sites that give a potted description of the group3 standard. Do a google or take a look at http://www.appsig.com/products/tn048.htm

Is their anything I can check in device manager for you to be 100% sure it is a data/fax modem?

Second question
How are these modems working are they analog or digital modulation.
What's their carrier frequency do they get assigned a frequency by the telephone company. Like is their a special DSLAM modem or headend that gives them an upstream and downstream frequency or do all these modem's use the same frequency but sence their on seperate lines (point to point it doesn't mater if they use a standard frequency for all modems since their on seperate lines anyway not shared network like cable)

I guess I don't know how dialup works thought it was just modulating data on the voice signal 20hz to 20khz. Is it modulated digitally or just like FM or AM modulation.

Also with these modems are they full duplex mean can they recieve data at the same time they are sending data?

[AlexR]

You could try connecting to the modem using hyperterm.
Make sure you can talk to the modem by issuing a wake-up and AT command "+++AT"
The modem should respond with an "ok"
If that works issue command "AT+FCLASS=2" this puts the modem into fax mode. If the modem responds with "ok" it is capable of working in fax mode.

Data rates, carrier frequencies and modulation schemes are set by the various standards used for data transmission. During the set-up phase of a fax call the machines/modems use the V21 standard which sends data at 300bps data using FSK modulation, a binary zero is represented by 1850 Hz, and a binary one is represented by 1650 Hz. Once the set-up phase is complete and the two machines/modems have agreed on what features will be used the actual fax data is sent using the V29 standard which uses a complex form of phase and amplitude modulation and a data rate of up to 19200bps.

Where in the hyperterminal program do you do this?
And how ???

I am assuming you mean the hyperterm program under communications which is under Accessories under the startup menu.

Thanks for the help on the modulation stuff

under device manager I queried the V.92 modem
I got this in the log

Nothing was connected to the rj11 jack when I queried it
Maybe this helps ?

That looks ok, the AT+FCLASS query came back with a list of options that includes fax option (AT+FCLASS=2) so your modem should work fine with the fax program.

One further step - the fax document is an image file, not a Word document file - http://www.faqs.org/rfcs/rfc3250.html

The extended TIFF format may be overkill, but the fax standard wants a file in TIFF format, not .DOC.

[StayatHomeElectronics]

I use a fax from my Windows XP PC quite frequently. The fax software that I have, PhoneTools which came with the PC, lets you attach files and it takes care of the conversion into the faxing image. There is a huge list of documents you can attach and .DOC is definitely one of them...

[beenthere]

That's better than having to scan documents into a TIFF file...

[blueroomelectronics]

Since it's a winmodem you'll need drivers for it that support the OS. You can buy a real modem cheap enough on eBay.
