Features
See "Personal Lines" in Chapter 2 of
System Reference.
Group Coverage
Assign secondary Individual Coverage for senders whose calls need less
frequent coverage—for example, users who provide backup only during peak
calling periods.
Calls received on personal lines programmed for immediate or delayed ring are
eligible for coverage. Calls on personal lines programmed for no ring are not
covered.
If a principal user is assigned, all calls are sent to the principal's receivers only.
If the principal user has Remote Call Forward, calls are sent to an outside
number rather than the coverage receivers.
Planning Form Instructions
Review the Employee Communication Survey analysis and determine
which users (senders) need Individual Coverage.
To set up Individual Coverage, program Cover buttons on the receivers'
telephones. Locate the specific receiver telephone forms from copies of
PBX System Form 4a, Analog Multiline Telephone
PBX System Form 4b, DIgital/ISDN (MLX) Telephone
PBX System Form 4c, Tip/Ring Equipement
PBX System Form 5a, Direct-Line Console (DLC) - Analog
PBX System Form 5b, Direct-Line Console (DLC) - Digital/ISDN
Use PBX System Form 2a, System Numbering - Station Jacks for
sender information. Use Form 4a, 4b, 4c, 5a, or 5b to record this information.
1 . On the forms for the sender telephone(s), under the "Individual Coverage
Receivers" heading, write the extension number for each primary and
secondary receiver in the spaces provided.
2 . On the forms for the receir telephone(s), locate an available button on
the "Button Diagram" and write "Ind Cover" and the sender's extension
number. Write "P" to indicate primary or "S" to indicate secondary
Individual Coverage.
Note: Single-line telephones cannot be receives, and QCCs cannot be
senders or receivers.
In Group Coverage, senders are organized into groups and calls received by
any member of the group are sent to a receiver.
Any type of telephone (excluding QCCs) can be a member of a coverage
group; however, no individual sender can be a member of more than one group.
A maximum of 30 coverage groups can be set up, and there is no limit to the
number of senders in each group.
