T1 8-Port Line Module Description
TheT18‐PortLineModuleprovideseightindependentoutsideplantconventionalT1inter‐
facestoacustomerorbetweenTotalAccess5000systemswithorwithoutspanpower.Each
interfaceconsistsofafour‐wireT1interfacebetweenaTimeDivisionMultiplex(TDM)
networkandanIPnetwork.
TheT1
8‐PortLineModuleconvertsEthernetpacketstoaTDMstream.TheT1interfacesare
usedtotransporttheEthernetpacketsfromoneTotalAccess5000shelftoanother.The
moduleimplementstheEthernetFirstMile(EFM)protocoltofragmentanddefragmentthe
packetsintobondedT1channelsofvariousbandwidths.
Withaspansupplydaughterboard,eachT1cansupply–130VDCor±130VDC(260VDC

includesaGroundFaultInterrupt(GFI).Thespansupplycanbeconfiguredasopen,source,
orloopbackforthe
spansupplycurrent.
TheT18‐PortLineModulecanoperateinredundantmodewheretheleft‐mostmoduleinthe
