Contents • • • • • • • • • • • • 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 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 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 series high-end machines, and the 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. Impact [ ] The Meridian has 43 million installed users worldwide, making it the most widely used. The Meridian was one of the few PBXs still available from a major communications supplier that can be configured as non- PBX and could be upgraded to a hybrid system with VoIP added. Current 1140E IP set for use on BCM and CS1000/2100 Nortel/Avaya systems The Nortel Meridian 1 can be upgraded to support in two forms: • VoIP Trunking, the Meridian 1 can have ITG-Trunk cards added to it to support PBX-to-PBX voice trunking using H.323 • VoIP Line (VoIP Sets), the Meridian 1 can have IP Line cards added to it to support VoIP sets.

Nortel Meridian 1 PBX. Use the phrase 'Meridian Option' to refer to the Meridian 1 range, to distinguish it from the smaller and larger Norstar and SL-100. Norstar Integrated Communications System (ICS) Although many Norstar's have been replaced, there are still a huge number in the field. The notes and PDF's here should be enough to help with most programming issues.
