Plessey Co Plc’s long-running negotiations with the People’s Republic of China over its ISDX digital PABX have culminated in its successor company, GEC Plessey Telecommunications Ltd signing a technology transfer agreement for the PABX to be manufactured by newly-formed Shanghai Digital Telephone Equipment Co. The agreement is valued at UKP120m over its 15-year term. GEC Plessey will have 26% of the company, in partnership with China International Trust & Investment Co, Shanghai Telephone Equipment Factory, and Lityan Development of Singapore. Initial investment by the four is reportedly UKP8m. Technology transfer will be phased over four years, with the ISDXs initially simply assembled from kits. The target is annual output of 100,000 lines of ISDX, 20% to be exported in South East Asia. The UK government will be putting up UKP3.5m loans and UKP2.9m grants for the project.
