Features
Note: Group Coverage can be used alone or can be set up to work with either
primary or secondary Individual Coverage, or both. This allows callers to get
personal attention from the primary and/or secondary Individual Coverage
receiver and backup from Group Coverage. For example, a receiver such as a
secretary can have a Primary Cover button to provide Individual Coverage for a
sender who is also a member of a coverage group.
Decide the interval for Coverage Delay and for Delayed Ring (the number of
rings before a receiver telephone with the Delayed Ring option begins to ring).
You can change the factory-set, three-ring Coverage Delay Interval to an interval
of from one to nine rings. The factory-set Delayed Ring Interval of two rings can
be changed to an interval of from one to six rings.
Note: The ringing pattern heard by an outside caller is shorter than the audible
ringing heard at an MLX or analog multiline telephone even though the total time
is exactly the same. An outside caller hears from one to two rings in addition to
the number of rings programmed for the Delayed Ring Interval and Coverage
Delay Interval. For example, if the Delayed Ring Interval is programmed for two
rings and the Coverage Delay Interval is programmed for one ring, an outside
caller hears four rings before the call is sent to coverage. If both intervals are set
to their maximum values, the caller will hear two additional rings.
Planning Form Instructions
Review the Employee Communication Survey analysis and determine the
senders to be grouped. Record both sender groups and receivers on PBX
System Form 6d, Group Coverage.
Note: Form 6d holds information for eight coverage groups. Duplicate the
form if more groups are planned.
Locate PBX System Form 2a, System Numbering - Station Jacks for
sender information and the specific recer forms from copies of PBX
System Forms 4a through 5b.
Under the "Coverage Delay Interval" heading at the top of Form 6d:
1 . Check "3 rings" to keep the factory-set interval.
2 . Check the second box to change the factory-set interval. Write the
number of rings in the space provided.
Under the "Dlayed Ring Interval" heading:
3 . Check "2 rings" to keep the factory-set interval.
4 . Check the second box to change the factory-set interval. Write the
number of rings in the space provided.
