2.1.1.2 RHU 1000 Rear Panel
The RHU 1000 rear-panel provides the control, RF interface and optic interface ports that enable
connecting an MA 1200 add-on unit to the RHU 1000 module.

Add-on control Transmits the control signals from MA 1200 add-on module to the
RHU 1000 module. Connected to the MA 1200 add-on Control
From port.
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
1200 rear panel: DL to DL, UL to UL.
2.1.2 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
RHU 1000 module. The RHU 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, WLAN 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 850/860 ports.)
NOTE: The units are integrated through simple external cable connections between
corresponding ports.
