Digital Host Unit
The DHU provides the input interface for RF
signals from a base transceiver station (BTS), or a
bi-directional amplifier (BDA). The DHU converts
the RF signal into a digital format and distributes
the digitized signal over fiber to multiple output
ports, either Digital Expansion Units or Digital Re-
mote Units. The DHU also performs power and
alarming functions for the system. Alarms are
accessible via dry contact closures. The DHU also
has alarm status LEDs. The DHU is typically wall-
or rack-mounted in a basement or other point of
entry within a building requiring coverage.
Digital Expansion Unit
The DEU is used when more than six remotes are
required to serve a building. The DEU receives
the digitized signals from the DHU and distri-
butes them over fiber to multiple digital outputs.
These outputs can be Digital Remote Units or
additional Digital Expansion Units. The DEU has
alarm LED indicators. The DEU is typically wall-
or rack-mounted in a wiring closet within the
building requiring coverage.
Digital Remote Unit
The DRU receives the digitized signals from the
DHU or intermediate DEU, converts the signals
back into RF, and interfaces with the antennas to
amplify the RF signals throughout the building.
The Digital Remote Unit is a compact module
that is typically mounted above ceiling tile.
