The MBS uses a two second tone (or splash tone) to identify certain
types of calls.
For example:
A second incoming call if off-hook
An intercom call
The "ring again" feature
Sometimes this tone is not loud enough. The DSI can be configured to
provide a louder tone through its own speaker. When the DSI's internal
speaker rings, contacts will close to power auxiliary equipment
connected to the AUX EQPT jack on the DSI. Auxiliary equipment is
optional. Examples of auxiliary equipment are loud ringers or beehive
lamps.
