UM-1000, Revision 2.2
3.2.1.2 RIU Rear Panel
The rear-panel provides all the connections on the BTS side and on the BU side as
well as connections to the MobileAccess 410/430 controller and the power
connection. Two types of BTS side connections are available for each BTS
conditioner: simplex and duplex.
ATTENTION
1. The RIU is factory set to 0dB gain on the uplink and
downlink. In order to operate properly, an ADJUSTMENT
process is required in the field.
2. Any unused input and output connectors MUST be
terminated with 50 ohms – otherwise the ADJUSMENT
procedure results may be affected.
3.2.1.3 RIU Connections
1. Connect each Base Unit to the corresponding pair of RF outputs on the RIU
rear panel. Note that one uplink and one downlink RIU rear-panel connector
is used to connect one OPTM (four ports from the BU). To connect
additional BUs, refer to Connections to Additional BUs.
2. Connect the BTS/BDA connections (either simplex or duplex), the controller,
and the power connections.
