The company was founded by

dot-com boom of the 1990s, with the 1995 purchase of Telecom Analysis Systems (located in
Eatontown, New Jersey) and the 1997 purchase of businesses such as Adtech, a digital test equipment concern based in Hawaii and the company was a member of the
FTSE 100 index from time to time. It disposed of its automotive industry businesses in 1999, the same year that it bought Netcom Systems, a US
telecoms testing business which makes network equipment testers, and DLS, a Canadian
telecoms testing business. In 2000 it also bought Hekimian, a major
Operations Support Systems business, Zarak Systems, another communications software business and Net-Hopper, an access systems specialist.
