External Tone Ringer

FEATURE
DESCRIPTION
The External Tone Ringer provides a common audible tone signal with relay
contacts for control when incoming CO/PBX calls are received in Day and
Night Mode. The relay contact closures may be used for external bells or
chimes. When an Attendant is not available, station users may respond to
the external ring signal and answer incoming calls. This feature provides for
wide area coverage or loud ringing for noisy locations when there are
incoming CO/PBX calls to be answered.
