Context

When the distance between an RRU and a remote control unit (RCU) is longer than 5 m (16.4

ft.), an AISG multi-core cable cannot connect the RR and the RCU because it is not long

enough. In this case, an AISG extension cable is used to extend the AISG multi-core cable.

Procedure



Install the AISG multi-core cable without installing the AISG extension cable.

a. Connect the waterproof DB9 connector at one end of the AISG multi-core cable to

the RET port on the bottom of the RRU, as shown in Figure 8-18.

RCU.

c. Route the cable by referring to section "Cabling Requirements". Then, use the cable

tie to secure it.

d. Label the installed cable by referring to Attaching an L-Shaped Label.
