3.3.1.2 Multiplexer
The multiplexer separates the various band frequencies respectively. The duplexer is used to make the
bi-directional signals into simplex signals and provides sufficient isolation.
3.3.1.3 Mounting
The BCM enclosure is installing on the 19’’ rack.
3.3.1.4 RF Connection
The RF signal connections with the antenna combiner are supported through 10 N-type female connectors.
These ten N-type connectors are used for coaxial cable connection to the Antenna ports of the single-band
RUM enclosures. Two 7/16 DIN connector is used to interface the combined multi-band RF signal to the
service antenna.
3.3.1.5 User Interface
The BCM enclosure interface consists of the two kinds of connectors that are provided on the front panel.
The BCM enclosure user interface is described in Table 6 and indicated in Figure 12.

3.3.2 Single-band RUM Enclosure
The Single-band Remote Unit (RU) enclosure provides forward and reverse amplification of the RF signals
within the specified band. Its enclosure accommodates the remote single-band modules and protects them
from the environment. The enclosure consists of the housing, mounting brackets, and enclosed MCPA
(Multi-Carrier Power Amplifier), controller unit, duplexer modules. Figure 13 shows the single-band
enclosure dimensions.
