1Introduction
Telecommunication today is more then just phone calls.
Surfing the Internet with the computer, using the resources
of the company network via remote access, sending faxes,
communicating with external employees via e-mail: electron-
ic communications are opening up ever more interesting
possibilities all over the world. For this reason a high-perfor-
mance telecommunication network is essential.
With the AVM ISDN-Controller B1 PCI v4.0 you can connect
your computer to ISDN. ISDN stands for Integrated Services
Digital Network and is a digital telecommunications network
available internationally. Three essential features make ISDN
so convincing:
High Speed
Data is transmitted on each of the two available B channels
at a speed of 64 kbit/s. In practice, this guarantees quick
connections and short transmission times. The AVM ISDN-
Controller B1 PCI v4.0 can also bundle the two B channels,
doubling transmission speeds.
Integration of Services
All telecommunications services, including telephony, fax,
data transfer and video transmission, run over a single data
network with ISDN. This means that all available services can
be used with one ISDN access, making it possible, for exam-
ple, to make a telephone call on one B channel while simul-
taneously receiving a fax on the other.
Outstanding Transmission Quality
The third important feature of ISDN is the end-to-end digital
transmission of data, the basis for high transmission quality.
ISDN makes poor connections and faulty data transmissions a
thing of the past.
