ANSI, SCTE Busy on the Standards Front

The SCTE and the American National Standards Institute have been busy on the standards front, approving seven standards in the last week. The recently approved standards include:





  • SCTE 58 2012, "AM Cross Modulation Measurements," which describes a test procedure for the laboratory and production measurement of amplitude modulation cross modulation (AM-XMOD) that is present in broadband systems that carry frequency division multiplexed (FDM), amplitude modulated, analog video channels.


  • SCTE 62 2012, "Measurement Procedure for Noise Figure," which defines a method of measurement for noise figure of active cable equipment. It is intended for measurement of 75-ohm devices having type "F" or 5/8-24 KS connectors, and for the measurement of true broadband noise as opposed to narrowband disturbances.


  • SCTE 73 2012, "Test Method for Axial Load Temperature Cycling of Drop Cable/Connector Interface," is intended to evaluate the connection between the connector and the coaxial drop cable when it is subjected to a continuously varying environmental cycle.


  • ANSI/SCTE 24-21 2012, "BV16 Speech Codec Specification for Voice over IP Applications in Cable Telephony," contains the description of the BV16 speech codec. BV16 compresses 8 kHz sampled narrowband speech to a bit rate of 16 kbps by employing a speech coding algorithm called two-stage noise feedback coding (TSNFC), developed by Broadcom.


  • ANSI/SCTE 24-23 2012, "BV32 Speech Codec Specification for Voice over IP Applications in Cable Telephony," contains the description of the BV32 speech codec. BV32 compresses 16 kHz sampled wideband speech to a bit rate of 32 kbps by employing the TSNFC speech coding algorithm.


  • ANSI/SCTE 75 2012, "Test Point Accuracy," describes a procedure for evaluating the accuracy of internal and external RF test points as used to monitor input and output ports of cable equipment.


  • ANSI/SCTE 122 2012, "SCTE Recommended Optical Fiber Cable Types for Outside Plant Drop Applications," is intended to provide guidance in selection of a suitable outside plant (OSP) optical drop cable with respect to different application environments.
