This chapter describes the MA1000 system basic elements: MA remote modules (MA 100 RHU
and MA1200 Add-on) and the Base Units. Your system may include additional elements such as
MA 410/430 controllers, MA RIUs and MA850 or MA860 units; these are described in the
corresponding User Guides.
2.1 Remote Modules
The Optical to RF conversion of each service at the individual building floors is performed by
remote units corresponding to the service types. These consist of MA 1000 RHUs and in addition,
may include MA 1200 add on modules and MA 850 modules.
The configurations depend on the requirements of the site and the supported services. The
following sections describe each of the system elements.
NOTE: The connections as they relate to the MA 1000 system are described in Chapter
4 -
System Installation.
2.1.1 MA 1000 RHUs
Each RHU supports two different services (one high-band and one low-band). All RHUs are add-
on ready, meaning that their optic interface and control functionality can support a third (high-
power) service through the connections of a MA 1200 Add-on module (see section
2.1.2).
Each RHU 1000 is connected to the corresponding BU (located in the communication room)
through a fiber optic connection. Remote monitoring is provided through the BU connections to
the MA 410/430 controller (
1.4).
The RHU 1000 services, MA 1200 add-on service and data services (provided by MA 860) at each
location are combined and then transmitted over a common infrastructure to strategically placed
antennas.
