Stromberg-Carlson was a telecommunications equipment and electronics manufacturing company in the United States.
By 1980 General Dynamics was undergoing a significant change and in 1982, General Dynamics sold the Stromberg-Carlson operations in several parts. The Stromberg key-systems was sold to ComDial, the PBX/DBX division was sold to United Technologies and the Central Office division was sold to Plessey of the UK. Plessey eventually sold “Stromberg Carlson,” the DCO business unit, to Siemens AG in 1991.
The new company, Siemens Stromberg-Carlson, became the third largest vendor of central office switches in the United States—with a combined installed base of 5 million access lines. They continued to manufacture the Siemens DCO as well as the Siemens EWSD out of the Lake Mary facility, moving production of the EWSD from New York to Florida.
In 2006 the DCO line of Siemens Stromberg-Carlson was sold to GENBAND, a Next Generation Networking company based in Texas.
