External Tone Ringer
E-10
FEATURE
DESCRIPTION
The External Tone Ringer provides a common audible tone with relay contacts
for control when incoming CO/PBX calls are received in Day or 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 and
answer incoming calls. This feature provides for wide area coverage or loud
ringing for noisy locations where incoming CO/PBX calls are answered.
