Using a Single HSS Unit Chapter 10

4. Tighten the protective seal that is on the prepared cable over the RJ-45 connector.
5. Repeat for all ODUs that are to be collocated at the hub site. The next ODU to be
connected is inserted in SYNC 1, SYNC 2, followed by SYNC 3 and so on.
Using a Single HSS Unit
Figure 10-5: HSS Wiring schematic
The wiring, as shown in Figure 10-5 is self explanatory. The Sync signal path is less self evi-
dent. If we set ODU 1 (on SYNC 1) to HSS Master, then the Sync signal path is as shown in
Figure 10-6. 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, termi-
nating at both ODUs 1 and 5.
