2.2 MA Remote Location Elements
Service specific units located at each remote location convert the RF signals to optics and route
them to the coax antenna infrastructure. In addition, 802.11 data services may be added for
distribution at each remote location. The units are either housed in, or externally connected to, a
device or ‘enclosure’ that converges the data and voice services and provides the common
interface to the antennas.
The following types of service specific elements are available:
• Remote Units (RUs) – support two voice services
• MA 1200 Add-on – used to add an additional (third) service to the RU.
• MA 850 – converges data services from 802.11a/b/g APs
Two types of enclosures are available for the service specific elements at each remote location:
• 2000 Lite – supports up to 8 non-conflicting services
• 2000 Cabinet – supports up to 20 services from the same or different operators
NOTE: The voice services are converged by an 8x4 Combiner unit that is installed in each enclosure.
2.2.1 RU 2000
RU 2000 is a service specific module that is either housed in the MA 2000 Cabinet or connected
externally to the MA 2000 Lite.
It provides the following functions:
• Performs the optic to RF (and vice versa) conversion at the remote locations
• Supports two services – high-band and low-band
• Interfaces to the optic fiber from the BU
• Add-on ready – MA 1200 can be added to support an additional services
• Remote management - requires connection of host BU connection to a MA 410/430
