4-16 Group Assigned Features
Coverage allows calls to users (called senders) to be covered by one or more
telephones (called receivers). Coverage can be individual or group assigned.
These instructions are for both Individual and Group Coverage.
Individual Coverage allows a one-on-one arrangement in which calls from one
sender are covered by one or more receivers.
A sender can have calls covered by up to eight receivers, and a receiver (such
as a secretary) can provide Individual Coverage for more than one sender. Any
type of telephone can be a sender; only a multiline telephone with
programmable buttons available can be a receiver.
Individual Coverage is set up by programming a Cover button on a receiver's
telephone. The receiver must have a programmed Cover button for each sender
whose calls are being covered.
When a sender's telephone rings, the call is immediately sent to the receivers
and the lights next to the Cover buttons flash. The telephones ring depending on
the type of coverage and the ringing option set for each receiver telephone.
A receiver can provide
Primary Individual Coverage with the following ringing options:
Immediate Ring. The receiver's telephone rings at the same time the
sender's telephone rings.
Delayed Ring. The receiver's telephone rings after the Delayed Ring
Interval programmed for the system.
No Ring. The receiver's telephone does not ring.
Secondary Individual Coverage with the following ringing options:
Immediate Ring. The receiver's telephone rings after the sender's
telephone rings twice. This two-ring Secondary Delay Interval is fixed and
cannot be changed.
Delayed Ring. The receiver's telephone rings after the sender's telephone
rings twice plus the Delayed Ring Interval programmed for the system.
For example, if the Delayed Ring Interval is set to 2 rings, the receiver's
telephone rings after the sender's telephone rings four times.
No Ring. The receiver's telephone does not ring.
Both primary and secondary Individual Cover buttons can be programmed for
each individual sender as long as the maximum does not exceed eight
receivers.
Assign primary Individual Coverage when coverage is needed between two
users—for example, an executive who wants calls answered by a secretary, or a
DLC operator who routinely covers calls for another operator.
