MT88E39 FSK input gain
*1: Recommended by TIA/EIA-716. Bellcore has agreed to the values and will incorporate them into its future standards.
*2: ETS 300 778-1 (On-hook) Sep 97, ETS 300 778-2 (Off-hook) Jan 97.
*3: dBm = Decibels above or below a reference power of 1 mW into 600 ohms. 0 dBm = 0.7746 Vrms.
*4: dBV = Decibels above or below a reference voltage of 1 Vrms. 0 dBV = 1 Vrms.
*5: On-hook signal range. The Off-hook signal levels are inside this range: -30.78 to -7.78 dBm.
