Hardware Considerations - AT&T PARTNER II Release 3.1 Programming And Use Instructions

Hardware Considerations

Programming procedures use line and extension numbers. The line number
represents the line jack on a 206 or 400 module to which the outside line is
connected. Similarly, the extension number represents the extension jack on a
206 module to which the system phone or standard device is connected.
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 for a
system with maximum lines. Figure 2-2 shows the numbering scheme for a
system with maximum extensions. However, your system can have any number
of lines and extensions up to the maximum.
