1.1 Introduction
Thismanualprovidesdescriptionsandinstructionsforoperatorsresponsibleforconfiguring,
managing,andmonitoringtheMEOLinkModem.
1.1.1 MEOLinkModemOverview
TheMEOLinkModemisahigh‐performancemulti‐Ethernetportmulti‐channelpercarrier
(MCPC)satellitemodulator/demodulatorthatconvertsEthernetinputsignalsintomultiple
waveformintermediatefrequencies(IF)andviceversa.TheMEOLinkprovidesDVB‐S2
waveformbackwardcompatibilitywithfieldedmodemtechnology,whileaddingdual
receiverstosupportMEOsatelliteswithlosslesshandover.TheMEOLinkoperatesatspeeds
between5Mbpsand800Mbpswithsymbolratesfrom10to180Msps.Modulation
waveformsincludeQ‐/8‐/16A‐/32A‐PSK.AdaptiveCodingandModulation(ACM)and
AdvancedUplinkPowerControl(AUPC)featureshelpconservesatelliteresources.
TheMEOLinkishousedina2U‐high,19‐inch,rack‐mountenclosure.Themodemisusedin
fixedgatewayapplicationswithDopplerrateanduniqueantennahandoverfeatures
allowingforseamlessMEOoperation.MEOLinksupportsL‐bandIFsforeasyintegrationwith
standardterminalequipment.
Theunitstatusmaybemonitoredusingfrontpanelindicatorsandmaybeoperatedusing
theControlPlaneEthernet(1GigE)interface.Eitheraninternalorexternalreference
providesthenecessarytimingsignalsforthecircuits.Ifamalfunctionoccurs,alarm
indicationsaredisplayedviathefrontpanelindicatorsandtheControlPlaneEthernet
interfaceviaSNMPandHTTP.

1.1.6 MEOLinkModemWebandSNMPInterface
TheMEOLinkModemmaybefullycontrolledthroughtheWebinterface,theSNMP
Interface,orboth.TheWebinterfaceprovidesmodemcontrolfunctionsandservesasan
operator’sgraphicaluserinterfacetothemodem.HigherlevelM&Csystemsmayinteract
withthemodemthroughthemodem’sSimpleNetworkManagementProtocol(SNMP)
interface.
BothinterfacesareavailablethroughtheControlports(J12,J13).

TheMEOLinkModemisonecomponentofalargersystem.Figure4depictsabasicMEOLink
Modemsetup.

2.1 Setup
TheMEOLinkmodemControlPlaneEthernetsupportsthreetypesofM&Ccomponents—
theTFTPServer,theWebbrowser,andtheSNMPManager.TheTFTPServerallowsthe
modemtobootfromfilesontheserverratherthanfromflash.TheWebbrowserallowsfor
controlthroughmodem’sHTTP(GUI)interface.TheSNMPManagerallowsforcontrol
throughthemodem’sSNMPagent.
Note,notallinstallationswillutilizeallthreeM&Ccomponents.InstallationswithoutaTFTP
serverbootfromflashsincetheMEOLinkattemptstofirstbootfromaTFTPserverandthen
fromflash.InstallationswithoutanSNMPmanagerwilluseabrowsertomanagethemodem
throughtheHTTP(webGUI)Interface.
Thedatasource/sinkconnectstothemodemthroughdualredundantGigabitEthernet
ports.Notethattheseportsdonotsupport10/100Base‐T.
ThetransmitIFportconnectstoappropriatetransmitRFequipment,includingupconverter,
amplifier,andantenna.ThereceiveIFportsaresimilarlyconnectedtoreceiveRFequipment.
