10.2.2 Using a Single HSS Unit
Figure 10‐2: HSS Wiring schematic
The wiring for a single HSS is shown in Figure 10‐2.
The Sync signal path is as follows: If we set ODU 1 (on SYNC 1) to HSS Master, the Sync signal
path is as shown in Figure 10‐3. 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.
