3.1 Fusion Main Hub Overview
The Fusion Main Hub (shown in Figure 3-1) distributes up to three individual (Band
1, 2, or 3) downlink RF signals from a base station, repeater, or MetroReach Focus
system to up to four Expansion Hubs, which in turn distribute the signals to up to 32
Remote Access Units. The Main Hub also combines uplink signals from the associ-
ated Expansion Hubs.
Fusion is a multi-band system. One RF source (Band 1 or RF1) goes to the 35 MHz
band and the other RF source (Band 2 or RF2) goes to the 75 MHz band. Band 3 (or
RF3) goes to a 6 MHz sub-band of the 35 MHz band and is functional only with the
800/900/1900 RAU. The system installs in a 19" equipment rack and is usually
co-located with the RF source in a telecommunications closet.
