Planning your system
Continued from previous page
• All extensions that share the same line should share the same line group
number (4-15).
• You can connect fax machines or other non-system devices to AUXL3 or
AUXL4 on the back of the telephone (also called data ports), so they can
access line 3 or 4.
• See Optional spare battery, page 84 for information about installing spare
batteries to maintain basic telephone features in case of a power failure.
• Refer to the Feature menu section, page 18, to customize each system
telephone.
• The chart on the following page will help you plan your system.
- List the extension number, location, and model for each phone.
- For each 1080, decide whether you want it to be an auto attendant.
- Decide which phone numbers each extension should have.
- Plan your line groups. This is necessary only if all telephone lines are not
attached to all telephones. See LINE GROUP, page 43, for more information.
- Decide which 1070 and 1040 extensions will be assigned to which 1080
system extension mailbox (see the Forwarding to DTAD mailbox section
on the 1070 or 1040 user’s manual).
- Decide if any phones will have private lines. A private line only appears on
one set.
- Write your phone numbers in the spaces at the top of the chart.
You may want to make copies of this chart, in case your needs change.
