EXPANDING THE PHONE SYSTEM

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.

Line Groups

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 12 extensions, each sharing the first three lines, but being assigned to different Line Groups based on other shared or private lines.
