Alignment Tone—Technical Details
The alignment tone output from a module is available on Pin 5 of the RJ-11 connector, and ground
is available on Pin 6. Thus the load at the listening device should be between Pins 5 and 6. The
listening device may be a headset, earpiece, or battery-powered speaker.
