cable and the FR-3000s. The transceivers on the segments are then connected to the AUI ports on
the FR-3000s using an attachment unit interface (AUI) cable, up to 50 meters long. The link be-
tween the two
FR-3000s is made by attaching the fiber optic cable to the fiber optic ports on each FR-3000. The
repeater will transmit re-timed data packets, regenerate preambles, extend collision fragments, au-
tomatically partition problem segments, and automatically reconnect non-problem segments.
The FR-3000 also incorporates Cabletron Systems' LANVIEW diagnostic system. Should a prob-
lem arise, troubleshooting of power failures, collisions, cable faults or many other problems can be
diagnosed rapidly using a series of LEDs.
