Define System access

This command determines the directory number to be used for system access. Any number can be defined for system access.

There is no direct procedure for changing to a new number being in conflict with the existing one. In such cases we must first change to an arbitrary, vacant number and then change that number to the desired one.

The references to the previous numbers will remain and should either be deleted or replaced by the new number. See description of command group 56 listing commands referring to directory numbers.
