Hardware Installation Appendix HWinLink™ 1000 User Manual Release 1.9 H-3• HSS Client-Continue Transmission (HSC-CT): If the unit losessynchronization with the HSS Master, the link remains active. How-ever, without synchronization pulses, it is possible that this unit willcause interference.• HSS Client-Disable Transmission (HSC-DT): If the unit losessynchronization with the HSS Master, the link is dropped until thesynchronization pulses resume. This setting prevents the unit fromcausing interference.The remote ODUs that are not located at the hub site, are called Indepen-dent Units and do not require HSS hardware.Hardware InstallationHSS supports installation of up to sixteen collocated units. In addition toeach unit being connected to its IDU or PoE device, the collocated unit hasan additional cable that is connected to the HSS Unit. The HSS Unit is acompact, weatherproof (IP67) connector box that is installed on the samemast 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 usemust be closed with a protective cover.Figure H-4: HSS Interconnection Unit¾To 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 cableto SYNC 1.3. Connect the other end of the CAT 5e cable to the ODU connector labeledSYNC.Note• If you collocate more than eight radios, cascade two HSS Units withan HSS cable.• Ensure that the collocated units are connected in sequence fromSYNC 1. If an ODU is removed form the hub site, then all remainingODUs must be reconnected to maintain the connectivity.
