Introduction strategies towards B-ISDN for business and residential subscribers based on ATM

It is argued that introduction strategies for B-ISDN with a clear evolutionary path to the future must be worked out. Two strategies are described, along with their early application. The first is mainly intended for business customers and offers an initial-phase asynchronous transfer mode (ATM) cross-connect functionality. The second is for residential users and initially offers POTS (plain old telephone service) and narrowband ISDN and analog TV services. Both solutions can easily be upgraded step by step to a full ATM-based B-ISDN.<
