1476Ringing — Abbreviated and Delayed
20
Detailed description
Ring types fall into two categories:
Those that alert consistently and don’t change:
Ringing, in which the lamp flashes and audible ringing occurs
Silent ringing, in which the lamp flashes and audible ringing does
not occur
Those that transition from one ringing state to another:
Abbreviated ringing, in which ringing continues for as many cycles
as specified by the automatic abbreviated/delayed transition interval
and then changes to silent alerting
Delayed ringing, in which visual alerting continues for as many
cycles as specified by the automatic abbreviated/delayed transition
interval and then changes to ringing
For a station with call appearances that have either abbreviated or delayed ringing,
an abbreviated-ring button associated with that station’s extension can be assigned
on a different station. When one of those call appearances is being alerted,
pressing the button forces immediate transition of the alerting — that is, from
ringing to silence or from silence to ringing.
This feature is most useful in bridging situations in which some users want to be:
Audibly alerted to a call immediately upon its arrival
Audibly notified if the call has not been answered within a specified
number of rings or if they have indicated.
Able to stop the audible alerting if the call is not being answered by the
principal and the user is not able to answer the call.
Because ring type can be specified on a per-station basis, mixing ring-type
specifications within a station’s access to a particular extension is possible.
For Ringing — Abbreviated and Delayed, each call appearance must be:
Assigned a ring type
Administered to transition when the:
Abbreviated/delayed transition interval is reached or when the user
presses the abbreviated ring button
user presses the abbreviated ring button, regardless of the
abbreviated/delayed transition interval
