Features
Do Not Disturb (Programmable)
The Do Not Disturb (DND) feature is used to stop all calls to a station. System
programming can allow or deny use of the DND feature for each station. Parties calling a
station in DND will receive reorder tone. A keyset without a DND key can activate DND
via the feature access code. The ANS/ALS key will flash at 112 ipm (rapidly) when DND is
set. There is a programmable option to allow a C.O. line to override DND at its ring
destination if that destination is a single station.
Door Lock Release
Stations programmed to receive calls from a door phone can dial a code to activate a contact
closure for control of a customer-provided electronic door lock.
Exclusive Hold
Pressing the HOLD key twice will hold a call exclusively at a station so no other station
can pick up that call. Intercom calls are automatically placed on exclusive hold.
Group Listening
This feature allows users to turn on the speaker while using the handset. This allows a
group of people to listen to the distant party over the speaker without the microphone
turned on.
Headset Operation
Every keyset can be programmed to allow for the use of a headset. In the headset mode,
the hookswitch is disabled and the ANS/RLS key is used to answer calls. ANS/RLS key
lights steady red when the keyset is in headset mode.
Headset operation can also be achieved using a third-party supplied headset adapter.
Hearing Aid Compatible
All keysets are hearing aid compatible.
Line Queuing with Callback
When the desired outside is busy, the user can press the CALLBACK key or dial the access
code to place his/her station in a queue. The user will be called back when the line is
available (a maximum of 30 callbacks are allowed system-wide at one time including busy
station and busy trunk).
