ADCP-75-136 • Issue 1 • November 2002 1 SYSTEM FUNCTIONAL OVERVIEW The Digivance ICS is a digitally distributed antenna system that provides in-building coverage for wireless phone systems operating within the 800 MHz frequency bands used for SMR and NPSPAC (SMR+) communications. Large buildings typically interfere with the transmission or reception of cellular phone system signals by imposing high attenuation losses on RF signals.

System Overview Functional Block Diagram 1.4 Digital Fiber Optic Transport The DHU is connected to each DRU unit over a pair of either multi-mode or single-mode (depending on the type of optical transceiver specified) optical fibers. One fiber is used to transport the forward path optical signal.
ADCP-75-136 • Issue 1 • November 2002 optical transport connection. With 62.5 micron core multi-mode fiber , the optical path may be up to 500 meters in length. With 50 micron core multi-mode fiber, the optical path may be up to 750 meters in length. With 9 micron core single-mode fiber, the optical path may be up to 10 kilometers in length. Single- and multi-mode fibers may be used in the same system.
ADCP-75-136 • Issue 1 • November 2002 2 DIGTAL UNIT DESCRIPTION This section provides a description of the functions and features provided by the units that comprise the ICS system, a listing of terms used and their definition, and a table of specifications. 2.1 Digital Host Unit Description The DHU, shown in Figure 2, serves as the BTS servicing unit for the Digivance ICS.
ADCP-75-136 • Issue 1 • November 2002 2.1.2 Mounting The DHU may be used in both rack-mount and wall-mount applications. For rack mount applications, a pair of reversible mounting brackets is provided that allow the DHU to be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. When rack-mounted, the front panel of the DHU is flush with the front of the rack and the cable management tray extends 3.9 inches (99 mm) beyond the front panel.
ADCP-75-136 • Issue 1 • November 2002 2.1.7 Cooling Continuous air flow for cooling is provided by dual fans mounted on the right side of the housing. A minimum of 3 inches (76 mm) of clearance space must be provided on both the left and right sides of the DHU for air intake and exhaust. An alarm is provided that indicates if a high temperature condition (>50º C/122º F) occurs. The fans may be field-replaced if either fan fails. 2.1.
