    摘要: A method of and apparatus for the simultaneous transmission of voice and data information over the same PCM transmission channel. During periods when only voice information is to be transmitted, the analog voice information is sampled at a first sampling rate, thus providing a digitized voice rate equal to the transmission rate capability of the transmission channel. During periods when both voice and data are to be transmitted, the analog voice information is sampled at a second sampling rate less than the first sampling rate, thus allowing the merged voice and data information to have a total digitized transmission rate equal to the transmission rate capability of the transmission channel.
