SyncFrames
SyncframesareexchangedbetweencollocatedODUsusingLayer‐2broadcasting.
Domain
Topreventnetworkflooding,eachgroupofcollocatedODUsisconfiguredwithaninternal
“domainname”. Thedefaultnamemustbechangedtopreventsyncframesbeingreceived
overtheLANbyanotherODU,whichcouldbethenmistakenlyconfiguredasaclientofan
HSMatthewronglocation.
Discovery
DiscoverybytheHSMandHSCsisprovidedusingthefollowingchoiceoffilters:
UsingdiscoveryattheHSM,youcanselectonlythoseHSCsintheHSM’sdomain;when
configuringanewHSCyoumayusediscoverytopickthecorrectHSM.
VLAN
VLANisusedtoseparatesyncframesfromtrafficsoastogivesyncframeshighestpriority.If
youhavecollocatedODUsrunningclosetofullcapacity,failuretodoso,wouldresultin
excessivejitteranddroppedtrafficframes.
Bydefault,theVLANID1997andpriority7arereservedforHSS.YoumaychangetheVLANID
butnotthepriority.
InstallingCollocatedHSSoEODUs
EthernetServicesOnly
UseanIDU‐HforthecollocatedODUsinsteadofseparatePoEdevices.TheIDU‐Hhastwo
LANports,oneofwhichwillbeconnectedtoaswitch.
EthernetandTDMServices
ToattainLayer2connectivityforuptotwosuchODUs,youshouldconnectoneofthetwo
theIDU‐C(orIDU‐E)LANportstotheIDU‐HLANports.YoumayusethesecondIDU‐C(or
Caution
VLANTaggingshouldnotusetheVLANIDusedbyHSSoEandviceversa.
