Function
Transformer isolated winding connection 1.
Transformer isolated winding connection 2.
Active low indicates incoming ring signal. This is pulsed low by the AC ring signal, and is not a steady-state low during
ringing.
Return path for V_CC.
Driving this pin low asserts the off-hook condition. The hook switch LED is current limited by an internal 470Ω resistor.
Mute relay activation, active low. LED current is limited by an internal 470Ω resistor.
Provides power to the hook switch LED. Voltage is usually +5V (for 8mA LED current), but can be higher if an external
resistor is placed in series with the internal 470Ω resistor.
Connection to telephone line Ring conductor.
Connection to telephone line Tip conductor.
