Abstract
The Interim Broadband Network (IBM) of Deutsche Bun-despost Telekom (DBP TELEKOM) is a logical step in the development from the innovative optical-fibre technology to a network for individual broadband communication. Having established a total of 16 broadband exchanges connected by an extensive, supraregional optical-fibre trunk network and having implemented optical-fibre lines in many local net works, DBP TELEKOM put into operation the world's largest switched optical-fibre networkfor broadband applications in the field of individual communications in 1989. According to the present technical concept the IBN has a capacity of about 1000 to 1500 subscribers.
