7.8 Installing an RRU AISG Multi-Wire Cable and AISG
Extension Cable
This section describes the procedures for installing an RRU AISG multi-wire cable and AISG
extension cable.
Context
When the distance between an RRU and a Remote Control Unit (RCU) is longer than 5 m (16.4
ft.), an AISG multi-wire cable is not long enough to connect the RRU and the RCU. In this case,
an AISG extension cable is used to extend the AISG multi-wire cable.
Procedure
l Install an AISG multi-wire cable that is not configured with an AISG extension cable.
1. Link the waterproofed DB9 connector at one end the AISG multi-wire cable to the
RET port on the RRU bottom, as shown in Figure 7-12.
