During the ring burst signals of an incoming call,
the ringer output connects to ground (open
collector output). This 0V can be used to activate a
relay coil to drive a horn and/or lamp. This output
can sink a maximum of 100mA.
The audio system mute signal also sinks to ground
(0V), and can be connected to audio mute input of
a sound system. This signal is asserted during a call.
