Telephone wiring: a conduit for networking standards

The author discusses emerging standards for local area networks (LANs) on unshielded copper wires that are expected to make it cheaper and easier for computers to communicate in offices, factories, and laboratories. He describes two twisted-pair standards developed by the IEEE 802.3 working group, one, already approved, designed for data transmission at 1 Mb/s, the other at 10 Mb/s. The official designation of the 1 Mb/s network is 1BASE5, but it is known as StarLAN after the AT&T network from which it is adapted.<
