The Multi-Function Module (MFM) enables you to connect tip/ring (T/R) or
supplemental alert adjuncts to an MLX telephone. The MFM is a circuit board that
mounts inside the telephone. Adjuncts plug into a modular jack on the MFM. The
MFM is the only T/R adapter used with MLX telephones. You cannot install an
MFM in an MLX-20L telephone that is set up for QCC operation.

representative about getting a different power supply. With either type of power
unit, the total cord length cannot exceed 50 feet (15 m) from the telephone.

use the Hold or Pickup features.
The MFM uses one of the two channels when it is active. A channel carries a
voice or data call between the system and the extension. This means you cannot
use Voice Announce and Speakerphone Paging when an adjunct (such as a fax
machine) and an MLX telephone are in use at the same time. When Voice
Announce is in use, a person calling an MFM extension gets a busy signal; a
person attempting to call out from an adjunct extension with an MFM does not get
a dial tone. Also, an adjunct connected by an MFM cannot provide a switchhook
flash.
