Line and Station Capacity
The numbers of jacks in Table 2-1 are the physical jacks on each module. In
most cases, the number of physical jacks indicates capacity (the number of
lines and/or stations that can be connected to the module). The exception is the
100D module with one physical jack which, because of the system’s software
capabilities, supports 24 lines.
Use the AT&T Equipment List (supplied with your communications system)
to complete page 1 of Key System Form 1, System Planning.
Planning Form Instructions:
Under the heading "Size of Processor Module" check the box describing the
size of the processor module (small or large).
Under the "Lines" heading in the "Capacity" section:
1. Fill in the number of each type of line module in the appropriate area.
2. Add the "Number of Modules" column and record the result next to the
system totals.
3. Multiply the number of each type of module by the number of lines it supports.
Write the results in the appropriate line of the "Total Lines by Module Type" column.
4. Add the "Total Lines by Module Type" column and record the total line
capacity of the system.
