Distinctive Ringing, Tones and Flash Patterns
Distinctive Ringing, Tones and Flash Patterns provide extension users with audible
and visual call status signals. This lets users tell the type of call by listening to the
ringing/tones and watching the keys. It also helps users monitor the progress of their
calls. In addition, Distinctive Ringing lets multiline terminal users customize their
Intercom and trunk call ringing. This is helpful for users that work together closely.
For example, if several co-workers set their multiline terminals to ring at different
pitches, each co-worker can always tell which calls are for them. You can also
customize the tones the system uses for splash tone, confirmation tone, trunk ring
tone, Intercom ring tone and Alarm ring tone. Refer to the UNIVERGE SV9100
Programming Manual for more details.

Door Box

The Door Box is a self-contained Intercom unit typically used to monitor an entrance
door. A visitor at the door can press the Door Box call button (like a door bell). The
Door Box then sends chime tones to all extensions programmed to receive chimes.
To answer the chime, the called extension user lifts the handset. This lets the
extension user talk to the visitor at the Door Box. The Door Box is convenient to have
at a delivery entrance, for example. It is not necessary to have company personnel
monitor the delivery entrance; they answer the Door Box chimes instead. Any
number of system extensions can receive Door Box chime tones.
Each Door Box has a pair of normally open relay contacts that can connect to an
electric door strike. Use these contacts to remotely control the entrance door. After
answering the Door Box chimes, a multiline terminal user can press Recall to
activate the Door Box contacts. This in turn releases the electric strike on the
entrance door. The device connected to the Door Box contacts cannot exceed the
contact ratings shown in the following table:
The system can have up to eight Door Boxes. Six chime tones are available.

Do Not Disturb

Do Not Disturb blocks incoming calls and Paging announcements. DND permits an
extension user to work by the telephone undisturbed by incoming calls and
announcements. The user can activate DND while their telephone is idle or while on
a call. Once activated, incoming trunk calls still flash the line keys. The user may use
the telephone in the normal manner for placing and processing calls.
