CoreBuilder 5000 Token Rings Media Modules are equipped with:
Automatic, hardware-based beacon recovery on each module.
Beacon Recovery allows the modules to remove beaconing stations
from both backplane (hub-wide) and isolated (module-level) rings.
Beacon recovery software and the CoreBuilder 5000 Beacon
Recovery ASIC, which aids in the removal of beaconing stations.
Beacon recovery functions even in the absence of a management
module in the hub.
CoreBuilder 5000 Token Ring Media Modules provide accurate,
hardware-based address-to-port mapping, capable of mapping multiple
stations per port, even for networks that incorporate fan-out devices
and MAC-less stations (for example, network analyzers).
