• HSS Client-Continue Transmission (HSC-CT): If the unit loses
synchronization with the HSS Master, the link remains active. How-
ever, without synchronization pulses, it is possible that this unit will
cause interference.
• HSS Client-Disable Transmission (HSC-DT): If the unit loses
synchronization with the HSS Master, the link is dropped until the
synchronization pulses resume. This setting prevents the unit from
causing interference.
The remote ODUs that are not located at the hub site, are called Indepen-
dent Units and do not require HSS hardware.
Hardware Installation
HSS supports installation of up to sixteen collocated units. In addition to
each unit being connected to its IDU or PoE device, the collocated unit has
an additional cable that is connected to the HSS Unit. The HSS Unit is a
compact, weatherproof (IP67) connector box that is installed on the same
mast as the ODUs. All collocated units connect to this box via CAT 5e cable.
Prepared lengths are available for purchase.
The HSS unit is supplied with ten protective covers; any port not in use
must be closed with a protective cover.
Figure H-4: HSS Interconnection Unit
¾ To connect an ODU to the HSS:
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.
Note
• If you collocate more than eight radios, cascade two HSS Units with
an HSS cable.
• Ensure that the collocated units are connected in sequence from
SYNC 1. If an ODU is removed form the hub site, then all remaining
ODUs must be reconnected to maintain the connectivity.
