Instruction manual

Features
The numbers in Figure 34 are arranged in rows according to the first digit. The
type of equipment, jack, or feature to which they are assigned is indicated in
each block within the row.
Each of the first 58 station jacks defaults to a 2-digit extension number
beginning with 10 and ending with 67. The rest of the extensions (station jacks
68-144) are assigned the 4-digit extension numbers 6800-6885.
The extension numbers shown for Multi-Function Modules (MFM) (710-767) are
reserved for digital station jacks. These numbers are automatically assigned by
the system to MFM adjuncts (such as a data terminal, answering machine, or
fax) connected to an MLX telephone using an MFM. For the first 58 digital
station jacks (numbered 10 through 57), the extension number assigned to the
MFM adjunct is the extension number assigned to the MLX telephone preceded
by a 7. For example, if the extension assigned to an MLX telephone is 25, the
extension 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 station jacks are shown in Figure 34 as Extra Stations (6800-6885)
and additional MFMs are shown as Extra Adjuncts (6900-6985). If Extra
Stations (station jacks) 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 100. For example, if the extension assigned to an MLX telephone
is 6800, the extension for the MFM adjunct on that telephone is 6900. In this
example, a call can be made to the telephone by dialing 6800 or to the adjunct
by dialing 6900.
NOTE:
■ The extension numbers are reserved whether or not an MFM adjunct
is connected to an MLX telephone.
■ If you renumber the extension number of the telephone, the system
does not automatically change the extension number of the MFM.
