3-Digit Numbering Plan
NOTE:
Extension numbers 0 and 100 both refer to the same operator position in
the 3-digit numbering plan.
Extensions default to 3-digit extension numbers beginning with 100 and ending
with 299.
The extension numbers (300–499) shown for adjuncts 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). The extension number assigned to an MFM (Multi-Function Module) or
direct adjunct is the extension number assigned to the MLX telephone, increased
by 200. For example, if the extension number assigned for an MLX telephone is
125, the extension number for the adjunct on that telephone is 325. In this
example, a call can be made to the telephone by dialing
125
or to the adjunct by
dialing
325
.
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.
