be individually alarmed and controlled. The optical path to each of the Microcell
Units may be up to 20 kilometers in length.

down link RF signals. The up link and down link signals are duplexed to a single
radiating antenna via a coaxial cable. Access to alarms and controls for the hub
and other Microcell Units are available via the control module.
