Figure 14‐2: HSS Wiring schematic
The wiring, as shown in Figure
evident. If we set ODU 1 (on SYNC 1) to HSS Master, then the Sync signal path is as shown in
Figure 14‐3. The signal travels from ODU 1 to SYNC 1, from SYNC 1 to SYNC 2, from SYNC 2 to
ODU 2 and back again. The back and forth paths repeat for the second to fourth ODU, from
left to right. The signal exits the HSS unit at SYNC 5 and terminates in ODU 5.
The choice of the ODU on SYNC 1 as HSS master is not mandatory, but is good practice. If for
example we were to use ODU 3 as HSS master, the Sync signal path would be ODU 3 to SYNC
3, then left and right to SYNC 2 and SYNC 4. It would then propagate to ODUs 2 and 4,
terminating at both ODUs 1 and 5.

Using More than One HSS Unit
In a large collocation site, several HSS units may be cascaded (daisy‐chained) subject to the
following conditions:
