Is there anyone that know of a modem that multiplexes voice and data
in a way that 

a) normal mode is voice, ie you have a telephone and use it, telephobne
is connected through the modems on both sides.

b) when a data transfer request is done to one sides modem, it interupts
the voice traffic, send an identifying signal to the other modem, and
starts to transfer data. When data is transferred the sender modem 
send an new signal to the other modem and the voice connection is
resumed.

c) The data connection does not need to be duplex, half duplex is
ok. (perhaps ebev simplex can do)

I am in heavy need of such a modem and would be very grateful 
for any hints on where to get one.
