Abstract :
This paper presents data characterizing the household phone line in the 1-60 MHz band. Two types of measurements were performed: transmission and noise sampling. The transmission measurements were done by using the impulse channel sounding method, so both the line attenuation and the delay spread were obtained. The noise measurements include: phone line background noise, phone noise, and noise sampled over a 24 hour period. Statistical characteristics of the delay spread, frequency response and noise can be extracted from the data and used in the design of phone line based communications systems
