Hardware Installation; Connecting An Hss Unit - Radwin WinLink 1000 User Manual

Hardware Installation

• HSS Client-Continue Transmission (HSC-CT): If the unit loses synchronization
with the HSS Master, the link remains active. However, 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 set-
ting prevents the unit from causing interference.
The remote ODUs that are not located at the hub site, are called Independent Units.
WinLink 1000 radios used as independent units do not require HSS
hardware.

Hardware Installation

Connecting an HSS Unit

A single HSS unit supports up to ten collocated ODUs. In addition to each unit being con-
nected 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 using CAT-5e
cable. Cables in 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.

Note

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.
WinLink 1000 User Manual
• For a single HSS unit, ensure that the collocated units are connected
in sequence from SYNC 1. If an ODU is removed from the hub site,
then all remaining ODUs must be reconnected to maintain the con-
nectivity.
• You may cascade (daisy-chain) two or more HSS Units with an HSS
cable. The method is described in detail below.
