Technical Details for Allied Telesyn AT 480

Allied Telesyn AT 480 ... managers with additional Attachment Unit Interface (AUI) ports from a single port transceiver that is currently installed on the Ethernet coaxial cable.

These multiport fanouts are transparent to the installed user hardware, thereby permitting support of the IEEE 802.3 standard, as well as being compatible with Ethernet Version 1.0 and 2.0. The AT-280 expands existing transceiver installations to two AUI ports while the AT-480 supports four AUI ports. Both fanout units can be installed with any existing standards-based transceiver used in thicknet (10BASE5), thinnet (10BASE2), fiber optic (FOIRL) and twisted pair (10BASE-T) installations.

The CentreCOM Multiport Fanouts feature four LEDs which simplify installation and assist in fault isolation. Each unit is equipped with LEDs for "Power," packet "Transmit," "Receive" and "Collision" detection.
