Chapter 14:
Serial Hub Site Synchronization
RADWIN Serial HSS
The RADWIN Serial Hub Site Synchronization (SHSS) method uses a CAT 5e cable connected
from the master ODU to all collocated ODUs; this cable carries pulses sent to each ODU,
which synchronize their transmission with each other.
Since the SHSS unit is still shown in the RADWIN Catalog as an "HSS unit", in the remainder of
this chapter we will continue with this convention on the clear understanding that we are
dealing only with SHSS.
Hardware Installation
Connecting an HSS Unit
A single HSS unit supports up to ten collocated ODUs. In addition to each unit being
connected to its IDU or 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.
