Using a Single HSS Unit

To connect an ODU to an HSS unit:
1. Unscrew the protective cover from the port marked SYNC 1.
2. Connect the RJ‐45 connector from one end of the prepared CAT‐5e cable to SYNC 1.
3. Connect the other end of the CAT‐5e cable to the ODU connector labeled SYNC.
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.

Figure 10‐5: 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 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,
terminating at both ODUs 1 and 5.
