PREDICTING PERFORMANCE OF TELEPHONE LINES FOR DATA SERVICES

摘要

A method characterizes a customer line for data transmission. The method includes measuring electrical properties of the customer line from a central location, identifying a line model from the measurements, and identifying a modem model for a modem selected for use with the customer line. The modem model gives performance data for the selected modem. The method also predict s performance data for the customer line when operated with the selected modem by combining the line and modem models.
