13.5 Telephone Influence Factor: The product does not exceed 25000 for any input and output
condition. Refer to paragraph 1.8.1.
1.3.6 Distortion: The peak to peak amplitude of any distortii in the to line AC voltage wave does not
exceed 20% of the RMS AC impedance produces no more than 2%
voltage when the bad. Refer to
