Numeris-ISDN in France

The development of Numeris, a nationwide integrated services digital network (ISDN) in France, and the accompanying repertoire of ISDN products is discussed. Numeris was commercially opened in France on December 21, 1987 and was made available nationwide three years later in December 1990. Numeris' growth exploded in 1991, increasing from 25000 sold B-channels at the end of 1990 to 150000 at the end of 1991; the goal is one million for 1995. The ISDN markets are reviewed, and the three needs that Numeris satisfies-application, computer networking, and PABX renewal-are described. A market forecast is presented
