Integrated broadband telecommunications network
The Integrated Broadband Telecommunications Network ( IBFN ) was a broadband network planned in the 1970s , similar to broadband ISDN (B-ISDN). It was included in the requirements planning at the time in the Bundestag as part of a digitization project from 1979 to 1985.
While B-ISDN was only intended to expand narrowband ISDN to include broadband individual communication services such as video telephony , the IBFN also intended to integrate the mass media broadband distribution services television and radio as a broadband distribution network . The IBFN is therefore also referred to as the universal network. The transition from narrowband telecommunication networks to the use of fiber optic-based broadband switching networks was planned by the federal government in 1992.
The first field tests took place from 1984 to 1989 as part of the BIGFON program. In view of the immense forecast costs for setting up a fiber optic network, the network was never implemented.
