Common Administrative Procedures
System Renumbering
The procedures in this section are used to reassign extension numbers for either
the 2-digit, 3-digit, and Set Up Space numbering plans.
NOTE:
System Renumbering is called Flexible Numbering in the MERLIN
â
II
Communications System. This is
not
the same as Board Renumbering, an option
used when modules in the control unit are changed.
This section contains the following programming procedures:
■
Single Renumbering
■
Block Renumbering
To reassign the system numbering plan or DSS Page buttons see Chapter 4,
“Programming Procedures.”
Use the single renumbering procedure any time 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 control 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:
Figures 3–1, 3–2, and 3–3 show the default settings in the gray spaces.
Extensions can be renumbered to any number shown in the white spaces.
