Overview of modules
3.3.2 Extension number plans of the add-on modules
The extension number plans of the add-on modules have been changed relative to that of
SW 2.0.1. The new assignment of the extension numbers and line numbers ensures consistent
numbering at all times whenever the system is expanded. Attention must be paid to the new
equipping sequence for extension and trunk modules.
