Starlan

[Fact 1]: Reuse of existing wires was critical in many building where rewire was cost prohibitive, or where running new wire would disturb asbestos of the building infrastructure.The TIA-568B wiring pinout standard was chosen, and pair 1 .

[Fact 2]: StarLAN provided the basis for the later standard 10BASE-T.A major design goal in StarLAN was the reuse of existing telephony wiring and compatibility with analog telephone signals in the same cable bundle.

[Fact 3]: Was the first implementation of Ethernet over twisted pair telephone wiring.The standard known as was developed as in the mid 1980s by members of the IEEE 802.3 standards committee.

[Fact 4]: Patented by AT&T, it was adopted by other networking vendors such as Hewlett-Packard and Ungermann-Bass.

[Fact 5]: This was considered revolutionary in 1984..

[Fact 6]: 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, on hook and off hook transients, or the 20 Hz high-voltage analog ring signal.

[Fact 7]: StarLAN ran at a speed of 1 Mbit/s.
