Organization: IEEE
Publication Date: 16 September 1999
Status: inactive
Page Count: 94
scope:

This standard provides the techniques for objective measurement of electroacoustic and voice switching characteristics of analog and digital HFTs. Due to the various characteristics of HFTs and the environments in which they operate, not all of the test procedures in this standard are applicable to all HFTs. Application of the test procedures to atypical HFTs should be determined on an individual basis.
