SmartLine 16 User’s Guide
Some Andrew MAUs, such as the SmartLine 16, use a technique
similar to “Phantom” voltage to determine whether they have an
active Rin/Rout connection. If “Phantom” voltage is removed, these
ports are taken off the ring.
Repeaters
A repeater regenerates and re-times the token ring signal. Repeaters
serve to extend cable distances between wiring closets. Some
repeaters also serve to extend lobe cabling to a distant workstation.
(See Andrew models TRR8416, TRx9416, and 8120 repeaters for
additional information.)
The re-timing feature of the SL8122 also helps minimize data errors
on the ring, thereby providing a more efficient network and
improving throughput. The Andrew SL8122s provide all of the
above features of a repeater in addition to acting as a copper-to-fiber
media converter.
