with power for the ODU. The PoE device is extremely
compact, having one Ethernet port, one ODU port and
a standard 3 pin male AC power socket. The unit is
supplied with a standard three pin power cable.
It may be used for both the HBS and the HSUs. It will

Hub Site Synchronization (HSS) Unit
The HSS unit synchronizes collocated ODUs to prevent self interference. It is particularly use-
ful at a multi-sector base station employing several HBSs.
A single HSS unit supports up to ten collocated ODUs. In addition to each unit being con-
nected to its PoE device, the collocated unit has an additional cable that is connected to the
HSS Unit. The HSS Unit is a compact, weatherproof (IP67) connector box that is installed on
the same mast as the ODUs. All collocated units connect to this box using CAT-5e cable.
Cables in prepared lengths are available for purchase.
The HSS unit is supplied with ten protective covers; any port not in use must be closed with a
protective cover.
