Note
Receiver performance in ITU-T V.34, V.32 bis, and V.32 modes may be degraded when transmitting above
-6 dBm.
Note
ITU-T V.34/V.32/V.32 bis, being echo canceling protocols, use signal quality as criteria for maintaining
connection. They also provide for self-training detection to force disconnect.
