• Operational Modes: Full or Half Duplex, Auto Dial, Auto Answer, Auto Redial, Tone or Pulse

• Line Equalization: Fixed compromised equalization in the transmitter, adaptive equalization in the receiver

• Transmit Level: -10 dBm ±1 dB at Tip and Ring. Can be attenuated.

• Transmit Tones: Answer Tone – an answer tone of 2100 Hz (V.22 bis, V.22 or T.30) or (2225 Hz Bell 212A or 103) is generated. Guard Tone: an 1800 Hz guard tone can be generated in all data modes. Calling Tone: an 1100 Hz (0.5 seconds on, 3 seconds off) calling tone (T.30) is generated in the originate fax mode.

• Receive Level: The receiver satisfies performance requirements for a received signal from -10 dBm to -43 dBm. The carrier detect is ON at -43 dBm and OFF at -48 dBm with a minimum of 2 dB hysteris.

• Transmit Frequency Tolerance (Hz): Less than ±0.01% at all frequencies
