Features
adjunct is the extension number assigned to the MLX telephone increased by
200. For example, if the extension for an MLX telephone is 7125, the extension
for the MFM adjunct on that telephone is 7325. In this example, a call can be
made to the telephone by dialing 7125 or to the adjunct by dialing 7325.
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.
