In Germany, ISDN also is headed for success, thanks to an incentive program for PC users and discounts for Basic Rate access. Deutsche Bundespost (DBP) Telekom expects the price-cutting incentives and growing base of ISDN applications to increase the current 14,000 ISDN customers to between 300,000 and 500,000 by 1995.
To encourage ISDN use, DBP Telekom gave a credit to any customer signing up for Basic Rate access who also bought an ISDN PC adapter card.
It provides basic rate access in a 2B+D format with two 64 kb/s B channels for audio, video, and data communication and one 16 kb/s D channel for packet mode oriented signaling, low speed data and telecommunication services.
