In Release 6.0 and later systems (Hybrid/PBX mode only), you may choose
non-local dial plan numbering to specify the numbering of extensions connected
to remote networked systems and allow users on your system to access those
extensions as if they were connected to your own system. You specify only ranges
of extensions.
Use the single renumbering procedure whenever the extension numbers you are
changing
from or to are not sequential.
Block renumbering is quicker, but you can use block renumbering only when the
extension numbers you are changing
from and to are sequential.
When trunk or extension modules are removed from the co ntrol unit, the
remaining modules must be rearranged so that no empty slots remain. The
system does not acknowledge any modules installed after an empty slot;
therefore, if the system is renumbered, extensions are not assigned to extension
jacks after the empty slots.
NOTE:NOTE:NOTE:
Figure 4–1, Figure 4–2, and Figure 4–3 show the default settings in the
gray spaces. Extensions can be renumbered to any number shown in the
white spaces.
