StarLAN was the first implementation of Ethernet computer networking on twisted pair wiring. Ethernet is a frame-based computer networking technology for local area networks (LANs). ...

Developed in the mid 1980s by members of the IEEE 802.3 standards committee, StarLAN ran at a speed of 1Mbit/s. This version of the standard was known as 1BASE5. It was adopted by other networking vendors such as Hewlett-Packard and Ungermann-Bass. MacGyver - 1980s hero The 1980s decade refers to the years from 1980 to 1989, inclusive. ...

The Hewlett-Packard Company (NYSE: HPQ), commonly known as HP, is a very large, global company headquartered in Palo Alto, California, United States. ... Ungermann-Bass, also known as UB, was a computer networking company in the 1980s to 1990s. ...

StarLAN provided the basis for the later standard 10BASE-T. With the addition of link beat, a feature to easily detect whether or not a cable was connected, and later full-duplex, a feature that enabled systems to transmit and receive at the same time, StarLAN's basic modulation scheme became 10BASE-T. 10BASE-T cable 10BASE-T cable and jackll 10BASE-T is an implementation of Ethernet which allows stations to be attached via twisted pair cable. ... Modulation is the process of varying a carrier signal, typically a sinusoidal signal, in order to use that signal to convey information. ...

A major design goal in the StarLAN technologies was compatibility with analog telephone signals in the same cable bundle. The signal modulation and wire pairing used by StarLAN were carefully chosen so that they would not affect or be affected by either the analog signal of a normal call or the 20Hz high-voltage analog ring signal. The telephone or phone (Greek: tele = far away and phone = voice) is a telecommunications device which is used to transmit and receive sound (most commonly voice and speech) across distance. ...

The TIA-568B wiring pinout standard was chosen, and pair 1 (blue) was left unused to accommodate an analog phone pair. Pairs 2 and 3 (orange and green) carry the StarLAN signals. This greatly simplified the installation of combined voice and data wiring in countries that used Registered jack connectors and american wiring practices for their phone service (connecting both to the same cable was a simple matter of using a pin-pin RJ45 splitter or punching down the same wires to two ports). This was considered revolutionary in 1990.
