It is important to ensure transmit and receive connections are made correctly to prevent
damage or field operational problems such as:
- Damage due to transmitting into a receiver port
- Crossed over diversity receive ports
- Crossed over sectors which could disrupt RF system design/optimization
Connect the external transmission lines from the diversity antenna systems to the RU
Antenna connections as shown in Figure 7-1. External connectors are “N-Type”.
Note that transmission line (or jumpers to transmission line) type and length will impact
the overall link budget calculations for the cell site. Be sure to include these losses in the
RF system design calculations for coverage.

7.2 RU Power Supply Interconnect Wiring
Connect the power interconnect cable between the RU main assembly and the RU power
supply as shown in Figure 7-3. Use only the cable supplied with the RU system for this
purpose. Tighten connector captivating screws to prevent accidental disconnection.
Connect the RU power supply alarm interconnect cable between the RU main assembly
and the RU power supply as shown in Figure 7-3. Use only the cable supplied with the
RU system for this purpose. Tighten connector captivating screws to prevent accidental
disconnection.
7.3 Ethernet/Serial Cable Wiring
Connect RU interface cable between the AW-96 RU I/F port and the RU RU I/F port as
shown in Figure 7-3. This connection allows the AW-96 to communication with RU
system for the purposes of transferring measurements, alarms and control functions. Use
only the serial cable supplied with the RU system for this purpose. Ensure the RJ-45
connectors are properly seated (“click”) to prevent accidental disconnection.
Connect the external Ethernet connections (cable not supplied) from the local Ethernet
switch or hub at the cell site to the BTS and BSC Ethernet ports on the AW-96 as shown
in Figure 7.3. Use category 5 Ethernet cable (or better) for best performance.
