The ARRIS OLL1000 (Offline Loader) is a specialized carousel server that provides the capability to rapidly load numerous code objects on various set-top box types in a warehouse environment or other staging area independent of the production system. The OLL1000 uses broadcast functions to clear stale code and/or configure mixed set-top types, so that no individual set-top addressing/configuration is required.The OLL1000 provides the warehouse with more control over code suites. It does so by keeping the loading independent, which has the added benefit of pre-loading set-tops in anticipation of planned code upgrades to support field installations on the day of the code upgrade. It is possible to create the code assignments for the new code a day or two in advance, providing the warehouse with more control over the code suites being pre-loaded.As shown in the figure below, the OLL1000 system consists of an OLL server, an OM1000/2000, and a population of set-tops. The OLL provides a canned OOB transport stream, necessary configuration messages, code download control messages, and a DCII-compliant code download object carousel to allow a set-top or host to download the desired suite of code objects for a particular warehouse or region.
