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

High Band
Connects to the

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.
Low Band
Connects to the Add-on Low 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 Add-on module. These
ports are connected to the corresponding ports on the ADD-ON
rear panel: DL to DL, UL to UL.
2.1.2 Add-on
The MobileAccess 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 RHU module. The 1000 RHU
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 Add-on and 1000 RHU services. (However,
in this type of configuration the combined services interface to the coax infrastructure through
the 860 ports.)
NOTE:
The units are integrated through simple external cable connections between
corresponding ports.
