Fig. 1 Computer with AVM ISDN-Controller B1 USB

The AVM ISDN-Controller B1 USB is completely

software driven. It is equipped with a flash-ROM BIOS that

permits a firmware update by means of a simple software

download. The ISDN software is also downloaded to the

Controller. This concept permits maximum flexibility and

makes it simple to adapt the ISDN-Controller hardware to

new technical developments.

Supported Protocols

The ISDN-Controller’s driver software is loaded from the

host computer’s hard disk. This software handles the

communications protocols and the data transmission.

The Controller software supports the international D

channel protocol DSS1 (”Euro-ISDN”) and the national

protocols 5ESS and NI-1 for the USA, Austel for Australia,

and 1TR6 for Germany.

The driver files for the D channel protocols used in

Germany, DSS1 and 1TR6, are included in the ISDN-

Controller package. The drivers for the other protocols

can be downloaded from the AVM Data Call Center by
