B. Channel-associated signaling utilizes a separate TDM channel for transmitting control signals.
C. Common channel signaling transmits control signals in band and therefore reduces the bandwidth available for the voice data stream.
D. Common channel signaling uses one of the TDM channels to transmit control information reducing the number of channels available for voice.
