2.1.1.1 RHU 1000 Front Panel

The RHU 1000 front panel contains the fiber optic connections to the BU, four coax connections
to the antennas, power connections and status indicators.

If RHU 1000 and MA 1200 add-on units are installed, then the combined services are fed to the
coax infrastructure through the
the combined

antenna ports

NOTE: To provide alarms, the antenna must supply a DC resistance of up to 5K ohms.

High Band Connects to the 1200 Add-on High Band port. Provides the

interface to the Add-on RF service which is combined with the RHU
services and distributed through the common coax infrastructure.

DL, UL Transmit the RF signals to- and from- the MA 1200 add-on module.

These ports are connected to the corresponding ports on the MA

2.1.3 MA 1200 Add-on

The MobileAccess 1200 Add-on module is a high power module, supporting a single frequency
band (low or high). It is designed to be integrated with a host
1000 module provides the following functionality for both units:

• Optical interface (to the BU) and conversion

• RF interface (to antennas) and conversion

• Control signals

In addition, MA 850 services can also be combined with MA 1200 add-on and RHU 1000
services. (However, in this type of configuration the combined services interface to the coax
infrastructure through the MA 850 ports.)

NOTE: The units are integrated through simple external cable connections between
corresponding ports.
