Logica Plc forecasts that the value of the European PABX market will grow by 39% to $3,050m in 1991 from $2,190m in 1986 in a report called PBX markets in Europe, part of the firm’s Telematica service. Growth will come from the replacement and expansion of Europe’s existing PABX base, spurred by the advent of Integrated Services Digital Networks, ISDN, in Europe, which promises the combined use of voice, data, text and video information. The consultancy predicts that the number of PABXs connected to ISDN in Europe will see its sharpest rise from 1989 to reach 37,000 by 1992. West Germany, the biggest market in Europe with 9.9m extensions in 1986 will see a 54% growth in value to $827m in 1991 from $534m in 1986. Details of the report, which was not received for review, can be had from Logica at 64, Newman Street, London W1A 4SE.
