Abstract
A facility is provided for measuring the signal-to-noise ratio of a transmission channel using the results obtained by transmitting over the channel a pseudorandom noise signal, in which the value of the signal-to-noise ratio may be used to determine whether the channel contains various types of pulse code modulation equipment.
