GEC Plessey Telecommunications (GPT) of Edge Lane, Liverpool

1986 The General Electric Company (GEC) attempted a takeover of Plessey in 1986 but was barred by regulatory authorities.

1st April 1988 GEC and Plessey Co merged their telecommunications businesses as GEC Plessey Telecommunications, commonly known as GPT. GPT was a world leader in many fields, for example Synchronous Digital Hierarchy (SDH) technology, and this brought the two companies responsible for developing and building the System X telephone exchange together, which was supposed to make selling System X simpler.

1989 GEC and Siemens acquired the Plessey Co through the joint company GEC Siemens plc. While most of Plessey was divided between the companies GPT remained a joint venture, with a 60/40 shareholding between GEC and Siemens respectively. GEC Plessey Telecommunications officially renamed itself GPT (no longer standing for anything) because Plessey no longer existed (except Plessey Semiconductors retained its name).

1996 GEC and Siemens AG agreed to form a JV to address the private network communication systems market; the new venture would takeover GPT's private network equipment, leaving GPT to concentrate on public networks[1]

1997 The name GPT disappeared from the market place on the formation of the new unit which was called SGCS (Siemens GEC Communication Systems); it was a JV of GEC and Siemens AG combining GPT Communication Systems with Siemens Business Communication Systems[2][3]

August 1998 GEC acquired Siemens' 40% stake in the remainder of GPT and merged with the telecoms units of its Italian subsidiary Marconi SpA, GEC Hong Kong and ATC South Africa to form Marconi Communications.
