Wireline Simulator.
Abstract
This report discusses the design of an all digital Wireline Simulator which reproduces most of the impairments normally encountered on a 4 kHz telephone channel. The simulator comprises a programmable digital filter, a frequency offset unit, an impulse noise generators, and interfaces with a general purpose digital computer and with input and output analog signals. The report provides a complete technical discussion of the simulator design. Also included are computer programs for controlling the response of the digital filter. The capabilities of the simulator exceed all the required specifications for producing the characteristics of the telephone channel. (Author)
