Central Answering Position

Forced Camp-on/Priority Override

Forced Camp-on allows a station to "camp-on" to another party involved in
an active call regardless of whether they have an internal or external call on
hold. When used with Priority Override, the capability is called Enhanced
Override. Forced Camp-on is activated automatically (if Automatic Forced
Camp-on, AFCO, is defined for the customer) or manually using the
Enhanced Override (EOVR) key on Meridian Digital Telephone sets, or the
Enhanced Override Flexible Feature Code on analog (500/2500-type) sets.
Associated with this feature are four new station Class Of Service entries:

•

CPFD/CPFA — Forced camp-on from another set denied/allowed.

•

CPTD/CPTA — Forced camp-on to another set denied/allowed.

These are used to identify the ability of a station to invoke the camp-on
feature or to be camp-on by another station.

The Priority Override feature allows an established call to be broken into
and another call presented to the desired party. Before break-in occurs, a
warning tone is given to all parties involved in the established call. The set
performing the override must have a priority level equal to or higher than both
sets being overridden. To activate Priority Override, the user of an analog
(500/2500-type) set must invoke a recall followed by the dialing of the
Override Flexible Feature Code, while the user of a Meridian Digital
Telephone presses the Override key (OVR). Priority Override can also
be activated using the Enhanced Override Flexible Feature Code or the
Enhanced Override key (EOVR), as described in the preceding paragraph.

Associated with the Priority Override feature are seven priority levels which
can be assigned to analog (500/2500-type) and Meridian Digital Telephones.
This level defines the ability of one set to override another as follows:

•

level 0 — This set cannot override and cannot be overridden.

•

level 1 — This set cannot override but can be overridden.

•

level 2 — This set can override level 1 and 2 sets and can be overridden
by sets with priorities 2–7. (This is the default level.)

•

level 3–6 — Similar to level 2 — Can override sets of equal or lesser
priority level other than 0, and can be overridden by sets of greater or
equal priority level.

•

level 7 — Can override levels 1–7, but can only be overridden by another
set of priority 7.

Note: Camp-on is not affected by the override levels.

A new Class Of Service (COS), named Override Denied/Allowed
(OVRD/OVRA), has been introduced for stations which defines the ability of
a station to use or be overridden by the Priority Override feature.
