Hardware Considerations
Programming procedures use line and extension numbers. The line number
represents the line jack on a 206 or 400 module that the outside line is
connected to. Similarly, the extension number represents the extension jack on
a 206 module that the system phone or standard device is connected to.
For each 206 module, the system assigns two lines and six extensions; for each
400 module, the system assigns four lines. The system numbers lines and
extensions consecutively. Figure 2-1 shows the numbering scheme—01
through 24—for a system with maximum lines. Figure 2-2 shows the numbering
scheme—10 through 57—for a system with maximum extensions. However,
your system can have any number of lines and extensions up to the maximum.
