A cell assembly apparatus is provided for a voice band signal used in ATM. A discriminating section (5) determines whether a voice band signal is "voice" or "data". When the voice band signal is voice, a voice detector (11) detects the presence or absence of voice in the signal. If silence is detected, a cell assembly section (13) prohibits transmission of cells. When the voice band signal is "data", a carrier detector (15) detects the presence or absence of a carrier. A cell assembly section (14) sends out a cell in response to the presence of the carrier in the input signal, while prohibiting the cell transmission when no carrier is detected in the input signal. <IMAGE> |
