This is pulsed LOW by the AC ring signal at the ring frequency from 15-40Hz. 4 I GND 5 I OH Driving this pin LOW asserts the off-hook condition. The hookswitch LED is current limited by an internal 470Ω resistor. 6 I MUTE 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 470Ω resistor. 7 I VCC Provides power to the hookswitch LED. Typically +5V for ≈ 8mA LED current. LED is current limited by an internal 470Ω resistor. VCC should not exceed 20V. 11 I/O RING 10 I/O TIP Top View Connected to host system ground. Connection to telephone line Ring conductor.
