Description / Abstract:
This Standard defines a model of the characteristics of the
Public Switched Telephone Network (PSTN) in the continental United
States of America to be used to measure modem transmission
performance. The model is intended to be a basis for performance
testing of 2-wire modems for use on the PSTN. The model includes
specifications for the configuration and setup of suitable
simulator equipment to be used in evaluations and comparisons of
such modems.
