EthernetHSSRequirements
TheRADWINEthernetHubSiteSynchronization(HSSoE)methodprovidesintra‐site
synchronizationwithouttheneedforexternalcablesoranHSSunit.Syncsignalsare
exchangedbetweencollocatedradiosovertheregularEthernetconnection.
TheEthernetHSS(HSSoE)methodrequiresLayer2Ethernetconnectivitybetweencollocated
ODUs.Ithastworequirements:
• Collocated ODUsprovidingEthernetservicesonly,shouldbeconnectedtoanIDU‐H
insteadofregularPoEdevices.Othersimpleswitchesmayworkwithdegradedper‐
formance.Theyarenotrecommendedandproblemsarisingfromtheirusewillnot
beeligibleforanykindofsupport.
• Collocated ODUsprovidingE1/T1servicesshoulduseanIDU‐CorIDU‐Eandthenbe
connectedtoanIDU‐Hfunctioningasaswitch.OneoftheLANportsontheIDU‐Cor
IDU‐EisconnectedtoanyofthesixIDU‐HPoEportsorthetwoLANports.(Thisis
possiblebecausetheIDU‐CorIDU‐ELANcableonlyusesfourpinsfordata;the
powerpinsarenotusedsothereisnoriskofdamagetothem.)Inthisway,upto
eightsuchODUsmaybecollocated.
Note
YoumayonlyuseoneIDU‐H.Thatis,theymaynotbecascaded.
Caution
IfyouareusinganIDU‐C0(GbE)itmustbeconnectedtotheIDU‐HLANport
only.ConnectingittotheP0Eportswilldamagetheunitandinanyevent,it
willnotwork.
