Transformer isolated audio signal coupling path for the telephone line. Active LOW indicates an incoming ring signal. This is pulsed LOW by the AC ring signal at the ring frequency from 15-40Hz. Connected to host system ground. Driving this pin LOW asserts the off-hook condition. The hookswitch LED is current limited by an internal 470 resistor. Driving this pin LOW activates the mute relay for pulse dialing. The mute control is activated on or slightly before (tpms max.) the start of the first dial pulse, then kept active until the end (50ms max.) of the last dial pulse. The mute relay LED is current limited by an internal 470 resistor. Provides power to the hookswitch LED. Typically +5V for 8mA LED current. LED is current limited by an internal 470 resistor. VCC should not exceed 20V. Connection to telephone line Ring conductor.
