LINE GROUP
If all of the sets have the default setting of  
LINE 4, and all the extensions in your system are 
connected to all lines, you can ignore this feature.
If there are extensions that have a private (not 
shared) telephone line connected to line 4, choose 
PRIVATE LINE. If you choose PRIVATE LINE
then call transfer, hold, call privacy, and other 
advanced features may not work correctly. Also, 
no messages can be recorded on the 1080 auto 
attendant mailbox for private lines on 1040 or 
1070 telephone sets.
If there are lines that some, but not all, sets share, 
connect them to line 4. Make sure that all those 
extensions have the same line group number, 
(
LINE 04 LINE 15).
Correctly assigning each group its own line group 
number allows the Line 4 indicator lights, hold, 
call transfer, and even ringing to work properly.
There is an example of a line group installation on 
the next page.
