Request for Question Clarification by lot-ga on 05 Aug 2002 16:16 PDT

Hello,
are you wanting to use the computer for analog modem internet/fax at
the same time as a voice call? - this isn't technically possible.

Only DSL technology will allow you to use the phone line for voice
calls at the same time as internet access. This option means you need
to take up broadband subscription.

Or are you just seeking a telephone line spliter so your computer
modem and telephone can be connected to the same telephone socket?

thanks

Thanks for the repley- There was a device on tv that allowed you to
use the computer and the phone at the same time. Have a great day
thank you for your time.

Hi spiderjohn, and thanks for the question. 

I must admit, I didn't think this was possible when I first read your
quesion as I had thought that simultaneous us of a single phone line
for both voice and data needed to multiplex the data digitally and
required DSL service, a DSL modem and a splitter.

However, my search for  simultaneous voice data +analog  produced
interesting results.

http://www.multitech.com/DOCUMENTS/datasheets/403.asp shows a product
from MultiTech Systems called the MultiModemDSVD. This product claims
"Patented simultaneous data and voice over a single analog phone
line...and Cost-effective with universally available standard phone
lines". It provides V.70 DSVD (digital simultaneous voice and data)
transmission,
V.90/56K downloads and 33.6K data rates for uploads or peer-to-peer
transfers. It will fax at 14.4K and is supported by Windows 3.1, 95,
98, NT and 2000 as well as Linux and other operating systems. It
retails for $179 US and the above mentioned page has links to find
their dealers as well as distributors.

At http://www.lucent.com/press/0596/960513.mea.html, you will find a
press release from 1996 approving the V70 standard that allows
simultaneous voice and data over analog modems, so the technology has
been available longer than I might have thought.Some of the
manufacturers that were original supporters of this technology include
Cirrus Logic, Inc., Compaq Computer Corp., IBM, Intel Corporation, the
Microelectronics Group of Lucent Technologies, Motorola, MultiTech
Systems and Sierra Semiconductor.

As a matter of fact, AT&T demonstrated this technology two years
earlier at Comdex '94 (http://www.att.com/news/1194/941109.gba.html).

Continuing to press on, I found that Creative Labs has a product
called the Modem Blaster V.90 that is an  "External Modem, V.90 &
K56flex, 56K, PnP, Caller ID, Simultaneous Voice/Data (SVD), Serial
Interface (up to 115Kbps), De5625, win3x/95/98/NT4/2000", as well as
an internal PCI bus version called the Modem Blaster 56K V.90 PCI.
Both of these are available at Micro Warehouse (www.warehouse.com) as
well as many other vendors, I'm sure. The external sells for about $70
(http://www.warehouse.com/product.asp?sourceid=00238151494435283054&pf_id=VW75202)
while the internal is less than $40
(http://www.warehouse.com/product.asp?sourceid=00238151495942799647&pf_id=VW12928).

Although it appears that these modems were manufactured by other
vendors such as US Robotics, I could not find current product listings
of this type. The key in locating a modem like this is to be sure it
supports SVD (Simultaneous Voice and Data) or DSVD (Digital
Simultaneous Voice and Data),

I hope this has been helpful.

Thanks to all of you ;-)

although this Question has expired i think i should add. DSVD did not
mean Simulatneus Voice and data per se. what DSVD did* was that one
could have a sumultaneus Voice and data (data being the Video
component)over the internet.it was implemented back when
k56flex(1997-98) was the rage (as opposed to 56K from US Robotics). u
could hold a normal telephone conversation.
http://www.agere.com/client/docs/BC99052.pdf
and 
http://www.56k.com   might provide more info on that 
that being said.. the newer V.92 Standard Does provide some sort of
share capability IF both your modem and your ISP support the standard.
u can use your modem normally and when a call comes in it tempreroly
puts your computer modem on hold for a limited time(upto 12 seconds)
which should be enough for u to decide if u want to take the call or
tell the person to call another time.
atleast upto the end of last year there was some disagreement between
the major vendors as to what was the standard defined as.So what might
work with one ISP might not work with another they might have worked
it out by now.but it would be better to check with your ISP.
that being said. as for the Ad on TV. I too have seen some ads on TV.
might be a different Ad than what u saw. but what i saw advertised was
a simple Switch over device.for shareing a fax a phone or a computer.
it answered the phone call . and based on the signal it heard on the
line switches the phone to your computer.. or fax. or if there is no
dats signal it rang the phone.. which U really don't need these days
unless u recieve incoming data calls on your computer.u can just plug
in your phone and if u have a fax attached it should answer if u set
it to recieve after the appropriate number of rings..
