The GSU is used when GPS synchronization is needed, but when the radio unit does not have
an internal GPS capability.
The GSU’s external connections are shown in Figure 4 ‐ 41 .
• Ground: Ground cable is attached to the ground lug
• Antenna: RF cable connects to the GPS antenna
• Sync: If you are not using the IDU ‐ H/HP to connect the radio units when using GPS
hub site synchronization, use this port to connect the ethernet switch. If you are
using the IDU ‐ H/HP (recommended), this port is not needed.
• Power (IDU): The IDU port provides both a power and network connection from a
PoE device via a CAT ‐ 5e cable.
• Network (IDU): The IDU port provides both a power and network connection from a
PoE device via a CAT ‐ 5e cable.
