Installing Multi-Function Modules
The Multi-Function Module (MFM) is an optional adapter that provides a
modular jack connection to MLX telephones for the two classes of
adjuncts listed below:
■ Tip/ring (T/R) devices such as single-line telephones, fax
machines, modems, and credit card verification terminals. Once
connected, the MLX telephone and adjunct work independently of
each other. This means both can send or receive calls at the same
time. The MFM is the only T/R adapter you can use with MLX
telephones.
■ Supplemental alerts such as bells, chimes, horns, and strobes.
These alerts notify people in noisy areas of incoming calls.
Considerations
Review the following items before you begin the procedure.
■ If you install an MFM, do so
before
you assemble the MLX
telephone.
■ You
must
connect the KS 22911 power supply to an electrical
outlet within 50 ft. (15 m) of cord length of the MLX telephone.
■ If you connect an MFM and two DSSs to a telephone, you
must
install a 406743419 power unit.
■ If a wall jack is more than 7 ft. (213 cm) from an MLX telephone,
you must use a longer D8W cord.
■ The MFM uses one of the two channels when it is active. This
means that when an adjunct, such as a fax machine, and the MLX
telephone are in use at the same time, Voice Announce to Busy is
not possible. (Voice Announce to Busy is a feature that allows
users to be paged on the speakerphone even if they are on a call.)
■ The MFM has two jumper blocks that are factory-set for T/R
operation. The MFM is packaged with the following items, shown
in Figure 3–1:
