History
Exploratory development on digital technology, common for the SL-1 (PBX) and the DMS (public switch) product lines, began in 1969 at Northern Telecom, while R&D activities related to the SL-1 started in June 1973. SL stands for Stored Logic.
It was introduced by Northern Telecom in December 1975, with an original capacity from 100 to 7,600 lines, and became the first fully digital PBX announced on the global market aimed at the smaller PBX market. In the early 1970s, most PBXs were either electromechanical (e.g. cross-bar) or based on a hybrid technology (e.g. switching matrix made from a two-dimensional array of contacts but control performed by an electronic logic). For this reason, the SL-1 enjoyed a great success on the enterprise market both in North-America and globally.
Its success went on to power the company into a leadership position in the telephony world, and led to expanded designs "up and down" to provide products at all sizes, including the DMS series high-end machines, and the Meridian Norstar for smaller installations up to 200 users. The SL-1 was gradually enhanced (peripheral hardware, packaging, etc.) and renamed Meridian-1 in the late 1980s. The Meridian-1 has evolved to support IP telephony and other next generation IP services.

Famous quotes containing the word history:
“The history of work has been, in part, the history of the worker’s body. Production depended on what the body could accomplish with strength and skill. Techniques that improve output have been driven by a general desire to decrease the pain of labor as well as by employers’ intentions to escape dependency upon that knowledge which only the sentient laboring body could provide.”
—Shoshana Zuboff (b. 1951)
“The history of the world is none other than the progress of the consciousness of freedom.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“Gossip is charming! History is merely gossip. But scandal is gossip made tedious by morality.”
—Oscar Wilde (1854–1900)
