The American National Standards Institute has approved four SCTE standards, three of which deal with HFC outside plant status monitoring.SCTE 38-3 2012, "Hybrid Fiber/Coax Outside Plant Status Monitoring SCTE-HMS-COMMON-MIB Management Information Base (MIB) Definition," defines common information about network elements (NEs). This includes administrative information such as name, ID, model number, serial number, vendor, and location; health indicators such as status and service state; and functional information such as power level and frequency range.SCTE 38-4 2012, "Hybrid Fiber/Coax Outside Plant Status Monitoring SCTE-HMS-PS-MIB Management Information Base (MIB) Definition," defines information commonly available from HFC power supplies. Its structure is intended to permit multiple power supplies to be monitored by a single transponder.SCTE 38-6 2012, "Hybrid Fiber/Coax Outside Plant Status Monitoring SCTE-HMS-GEN-MIB Management Information Base (MIB) Definition," is intended to provide the branch object identifiers for each of the MIBs within the SCTE HMS Tree.SCTE 36 2012, "SCTE-ROOT Management Information Base (MIB) Definitions," is intended to provide the root object identifier for the SCTE as an enterprise, as assigned by the Internet Assigned Numbers Authority. Any Management Information Base (MIB) that falls under the auspices of the SCTE must be assigned object identifiers underneath this enterprise object-id.All four standards are available at http://www.scte.org/standards/Standards_Available.aspx.
