3.1.2.2 RF Ports
3.1.2.2.1 DL IN/UL OUT & DPX ports
DL IN/UL OUT & DPX Ports (refer to Figure 3-7) are located at the back of RFU and can be connected directly to
the BTS. The RFU can support incoming signal strength from 0 to 25dBm(in case of BT and VU, -15~37dBm).
BT RFU does not have DL IN port because of TDD(Time division duplex) system.
VU RFU does not have DPX port because there is externally optional Duplexer customized by user requirement
for VHF/UHF system.
3.1.2.2.2 DL OUT/UL IN
DL OUT/UL IN Ports (refer to Figure 3-7) are located at the front of the RFU and connect directly to the HE
Channel Combiner (ADX-H-CHC).
3.1.2.3 Communication Port
The ADX-H-NMS monitors and controls the RFU via this port. DC Power is also provided to the RFU via this port.
