AllFiber-To-The-Homearchitecturesshareafundamentalelement-theassignmentofthephysicalnetworkconnectionfromthesubscribertotheserving location.Theassignmentof thisphysicalconnectivity reliesupon thephysical inventory for information suchas subscriber locationandavailability of infrastructure. It is in support of this process that Smallworld Physical ResourceAssignment (fully integratedwith the restof theOSS\BSS)candeliversignificantbenefitswhichenable“flowthrough”provisioning–theabilitytoseamlesslyqualifyifacustomercanbeconnected,assignnetworkandinitiatefieldactivities.
SmallworldPhysicalResourceAssignmentautomates theassignmentofphysical inventory toaservicerequest–whether that is fromwithin theoperator’sownbusinessor froma thirdpartyprovider. When a request is received Smallworld Physical Resource Assignment identifies thecustomerlocation(orifthisisnotavailableyettheclosestnetworkterminal)andthendeterminesthephysicalpathupstreamfromthatpointbacktoamainservinglocation,whichcouldbeastreetcabinetoracentraloffice.

This is becoming increasingly critical in the separated operatingmodelthatisbeginningtobeadoptedinmanypartsoftheworld.Inthismodelthetraditionalincumbentserviceproviderisseparatedintodifferent companies, typically a network company and an operating company.

It is absolutely critical that the OSS are sufficiently separated toensure that all processes operate independently. For examplephysicalassignmentcannotbeentwinedwithorderhandling,logicalserviceprovisioningandserviceactivation,aswasoftenthecaseinmanylegacysolutions.
