att 945 Manuale Utente

When you combine two or more 945/974/984/944/955/964 phones you
create an interacting system where phones share lines. If you have only
945/974/984 phones on your phone system, you can have up to 16 phones
and up to 19 telephone lines. If you have one or more 944/955/964 phones
in your phone system, you can have up to 12 phones and up to 15 telephone
lines. The system can be expanded with or without Centrex service.

NOTE: All 945 features work as described earlier in this manual.

When phones share lines, the LINE lights let users at different extensions
know when a specific line is in use. For accurate LINE lights, the same 
lines must be connected to each extension in the Line Group, and they must
have the same incoming telephone number at each extension.

The chart below shows 16 extensions, each sharing the first three lines,
but being assigned to different Line Groups based on other shared or 
private lines.
