Lanstar
LANStar (Lanstar) was a 2.56 Mbit/s twisted-pair local area network created by Northern Telecom in the mid '80s. Because NT's PBX systems already owned a building's twisted pair plant (for voice), it made sense to use the same wiring for data as well. LANStar was originally to be a component of NT's PTE (Packet Transport Equipment) product, which was a sort of minicomputer arrangement with dumb (VT220) terminals on the desktop and the CPUs in an intelligent rack (the PTE) in the PBX room (alongside the PBX). The PTE was to have several basic office automation apps: word processing, database, etc. Just as NT was doing Beta testing of the PTE, PCs and PC networking took off, effectively killing the PTE before it completed Beta. Given the investment already sunk into the product, NT attempted to repackage the PTE as a small (dorm-room-refrigerator sized) cabinet (the PTE-S, 'S' for 'small') containing only LANStar controllers and supporting up to 112 nodes. LANStar had cards for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meridian Mail
Meridian Mail is one of the early all-digital voicemail systems, running on Meridian1 / SL-1 digital PBX systems from Northern Telecom (later known as Nortel). In the early 1980s Northern Telecom introduced the Norstar. The Norstar was the first all-digital system suitable for small-sized offices (up to 192 lines), and became one of their major product lines. The Norstar is powered by a 16 MHz Motorola 68000, and uses only a fraction of the CPU's power. Nortel executives were interested in finding ways to use that excess power, as long as their customers paid for the privilege. Nortel asked their research arm, Bell Northern Research (BNR), to look for ways to spend those cycles. Meridian Mail was developed as a result. Meridian Mail was discontinued by Nortel, Discontinued [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

StarLAN
StarLAN was the first IEEE 802.3 standard for Ethernet over twisted pair wiring. It was standardized by the standards association of the Institute of Electrical and Electronics Engineers (IEEE) as 802.3e in 1986, as the 1BASE5 version of Ethernet. The StarLAN Task Force was chaired by Bob Galin. Description An early version of StarLAN was developed by Tim Rock and Bill Aranguren at AT&T Information Systems as an experimental system in 1983. The name StarLAN was coined by the IEEE task force based on the fact that it used a star topology from a central hub in contrast to the bus network of the shared cable 10BASE5 and 10BASE2 networks that had been based on ALOHANET. The standard known as 1BASE5 was adopted as 802.3e in 1986 by members of the IEEE 802.3 standards committee as the Twisted Pair Medium Access Control sublayer and Physical Signalling sublayer specification in section 12. The original StarLAN ran at a speed of 1 Mbit/s. A major design goal in StarLAN was reductio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
