Note: The recommended DAA (see the TDK 73M2901 Reference Manual) will result in approximately 8dB loss from the transmit pins to the

phone line. This includes the loss through the line matching impedance (475Ω resistor), transformer, and solid state off-hook relay.

¹dBm0 refers to the TDK recommended DAA ( 8dB loss from Transmit pins to the line and 5dB loss from the line to the Receive pin). Results

may vary depending on selected DAA. 0dBm = 0.775V_rms. dBm = 10log {Vrms²/[(1mW)(600Ω)]}
