Hi all
I'm trying to get a data/telecom switch box. It runs on the telephone cable
and allows me to connect fax, modem and phone to the same line without the
drop out I get with a simple tewo-way adapter.
Given the way the telephone system works, I think that you are
describing the idea that you'd like to have one line shared over
multiple devices that are potentially talking at the same time.
If this is the case, the answer is that you cannot.
If you are talking instead about switching between devices, this is
generally a case of picking-up the line on the device you want to
switch to and then hanging up on the previous device. Of course you do
need to know that a modem connection cannot be switched like this, since
a continuous tone - called the carrier - needs to be in evidence during
the whole modem conversation.
There are modems that support voice and data at the same time, but only
to another such-equipped device. It's mainly for two gamers who are
connected to each other and want to talk.
Finally, if you have an ADSL connection, then your phone line can
support both a data and a voice or fax connection at the same time - but
an ADSL line filter is needed to plug into the line to plug the
traditional phone device into - you'll still need a splitter:
--ADSL line --+-- ADSL filter --+-- Phone
| |
| +-- Fax
|
+-- ADSL modem -- Computer
Hope this clears up your request.
