ANSI Approves 4 SCTE Standards

The American National Standards Institute has approved four SCTE standards.ANSI/SCTE 197 2013, "Recommendations for Spot Check Loudness Measurements," provides recommendations for measuring content carried in a single programming channel of a program network for 24-hours as part of managing audio loudness.ANSI/SCTE 136-1 2013, "Layer 2 Virtual Private Networks for IP Cable Modem Systems," describes requirements on both CMTSs and cable modems in order to implement a DOCSIS Layer-2 Virtual Private Network (DOCSIS L2VPN) feature.ANSI/SCTE 77 2013, "Specification for Underground Enclosure Integrity," covers conformance tests and requirements for the integrity of grade-level enclosures containing telecommunication or other low voltage apparatus that may be exposed to the public.ANSI/SCTE 68 2013, "Drop Passives: Matching Transformers 75 Ohm to 300 Ohm," is intended to specify recommended mechanical and electrical standards for broadband RF devices whose primary purpose is to provide impedance and connector match between 75-ohm coaxial type F and 300-ohm twin-lead open screw connectorized devices.All four standards are available at http://www.scte.org/standards/Standards_Available.aspx.
