The scope of this project is objective test methods for determining the transmission characteristics of analog and digital telephone sets, handsets and headsets. (Original scope -- not changed) The purpose is to provide practical methods for making laboratory measurements of the transmission characteristics of analog and digital telephone sets so that their performance may be evaluated on a standardized basis. Revision is necessary to cover application to types of telephone sets not in common use and to measurements not required at the 1992 publication of the current standard. It also incorporates the content of IEEE 1206-1994 relative to handsets and headsets. (Original purpose -- not changed.) Amendment Standard - Superseded. This document amends IEEE Std 269-2002.
