244 Understanding how the system identifies lines
N0008589 3.3
Follow these steps to use the table.
1 For each bus number, circle the module you set to that number.
2
Beside the module name, circle the group of line numbers appropriate for the offset you set on
the modules.
3
In the Line pool column, indicate a line pool name if you want to associate lines into a pool.
This enables assigned telephones to grab any free line from the pool.
4
On the far right column, list the access codes and routes associated with the lines.
