System Renumbering
NOTE:
Extension numbers 0 and 10 both refer to the same operator position in the
2-Digit Numbering Plan.
Each of the first 57 extension jacks defaults to a 2-digit extension number
beginning with 10 and ending with 66. The rest of the extensions (extension jacks
67–200) are assigned the 4-digit extension numbers 6700 through 6842.
The extension numbers (710–766) shown for Multi-Function Modules are
reserved for MLX extension jacks. These numbers are automatically assigned by
the system to adjuncts connected to MLX telephones either using MFMs (such as
modems, answering machines, or fax machines) or directly (for example, a
terminal adapter). For the first 57 digital extension jacks (numbered 10 through
66), the extension number assigned to the adjunct is the extension number
assigned to the MLX telephone, preceded by a 7. For example, if the extension
number assigned to an MLX telephone is 25, the extension number for the MFM
adjunct on that telephone is 725. In this example, a call can be made to the
telephone by dialing
25
or to the adjunct by dialing
725
.
Additional extension jacks are shown in
as Extra Extensions
(6700–6842), and additional MFMs are shown as Extra Adjuncts (6850–6992). If
extra extensions are assigned, the extension numbers for extra adjuncts are
assigned by the system to MFM adjuncts. The extension number assigned to the
MFM adjunct is the extension number assigned to the MLX telephone, increased
by 150. For example, if the extension number assigned to an MLX telephone is
6700, the extension number for the MFM adjunct on that telephone is 6850. In this
example, a call can be made to the telephone by dialing
6700
or to the adjunct by
dialing
6850
.
NOTES:
1.
The extension numbers are reserved whether or not adjuncts are
connected to MLX telephones.
2.
If you renumber the extension number of an MLX telephone, the
system does not automatically change the extension number of the
associated adjunct.
3.
Digital adjuncts that use the system’s 2B Data feature use both the
adjunct and the main extension number of an MLX extension jack (see
‘‘Digital Data Calls’’ on page 183
for more information).
