2.8 Modem and ISDN card
MODEM
Modem is an abbreviation for "
MOD
ulator/
DEM
odulator". The
modem is a remote data transmission device, which
•
establishes a connection to a remote station,
•
converts (modulates) signals coming from the computer into
sounds,
•
sends these to the remote station,
•
and, used on the other end of the line, reconverts
(demodulates) the sounds received into machine-recognisable
signals.
There are countless standards – protocols – for modems to ensure
that they can communicate with one another. These standards are
defined by the CCITT (
C
omité
C
onsultatif
I
nternational
T
élégraphique et
T
éléphonique).
The most recent analog modem standard V.92 was confirmed by
the ITU (
I
nternational
T
elecommunication
U
nion). Downstream
communication is unchanged at 56 kbit/s. The three most
important improvements compared to the V.90 standard that is
widely used today are:
•
Upload at up to 48 kbit/s possible (only 33 kbit/s with V.90)
•
Faster connection setup
•
Supports
the
"
modem on hold
" function. This means that
when you receive a telephone call while online, you will be
notified. The modem function will be "parked" and you will be
able to return to your Internet function once you have
completed your phone conversation.
If you want to use this standard and your modem is compatible
with this standard, then find out from your provider whether they
support V.92.
