108434 2016.0202.007 Handset Synthetic casing keys and antenna with metal electrical contacts and screws     Unknown Unknown     1996   circa   8 Predominantly white synthetic with dark grey yellow green and translucent white buttons with dark grey markings. The handset also has a black antenna. Bell Northern Research was the research and development subsidiary of Northern Telecom (later Nortel Networks) and Bell Canada. It was built by Northern Telecom at its Trans-Canada plant in Montreal. Northern Telecom and its predecessor Northern Electric was for decades Canada¬ís largest manufacturer of telecommunications equipment. Originally a subsidiary of the AT&T-owned Western Electric for which it manufactured American-designed products for the Canadian market Northern Electric became Canadian-owned in the 1950s and in the 1960s began to design and produce equipment to meet the distinctive needs of Canadian telecommunication companies. In the 1970s through its new research subsidiary Bell Northern Research the company made a concerted shift from conventional analogue equipment into the emerging field of digital communications becoming in the 1980s the first equipment supplier to provide a complete line of fully digital switching and transmission gear. During this decade the company moved aggressively into export markets and opened manufacturing and R&D operations in several countries. The company¬ís sales soared during the internet boom of the 1990s but a combination of poor financial decisions and a failure to maintain its technological edge led eventually to its bankruptcy in 2009. The original Bell Northern facilities were designed with cutting edge telecommunications research and development in mind with the first three buildings on the campus featuring laboratories an extensive research library and an anechoic chamber. The anechoic chamber was the focal point of the Bell Northern Research acoustics research examining both the technology and placement of speakers and microphones in telecommunication devices. The anechoic chamber group was organized under the Industrial Design and working together with design were responsible for the development of the acoustic properties of most products. (From the Acquisition Proposal see Ref. 1) To receive and transmit telephone signals. According to David Cuddy former director of the Nortel Acoustics Laboratory this prototype was used to determine the acoustical properties of the intercom arrangement. To limit the acoustic interference caused by sound reflection and delay to the microphone the microphone is placed close to the surface of the table.
