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.
Five Do Not Disturb options are available at each extension. These options can be
accessed via multiline terminal Softkeys, DND feature key or DND system access
code.
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.
