Appendix H
Hub Site Synchronization
What is Hub Site Synchronization?
When several units are collocated at a common hub site, interference may
occur from one unit to another. RADWIN ODU units support the collocation
of up to 16 units at a central site.
For WinLink™ 1000, HSS support depends on the product model.
Using a method called Hub Site Synchronization (HSS) a cable is connected
from the master ODU to all collocated ODUs; this cable carries pulses sent
to each ODU, which synchronize their transmission with each other. The
pulse synchronization ensures that transmission occurs at the same time for
all collocated units. This also results in all of the hub site units receiving
data at the same time, eliminating the possibility of interference that could
result if some units transmit while other units at the same location receive.
Figure H-1
shows interference caused by non-synchronized collocated
units.
